	-+ GNU LESSER GENERAL PUBLIC LICENSE
	-+ Version 2.1, February 1999
	-+
	-+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
	-+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
	-+ Everyone is permitted to copy and distribute verbatim copies
	-+ of this license document, but changing it is not allowed.
	-+
	-+[This is the first released version of the Lesser GPL. It also counts
	-+ as the successor of the GNU Library Public License, version 2, hence
	-+ the version number 2.1.]
	-+
	-+ Preamble
	-+
	-+ The licenses for most software are designed to take away your
	-+freedom to share and change it. By contrast, the GNU General Public
	-+Licenses are intended to guarantee your freedom to share and change
	-+free software--to make sure the software is free for all its users.
	-+
	-+ This license, the Lesser General Public License, applies to some
	-+specially designated software packages--typically libraries--of the
	-+Free Software Foundation and other authors who decide to use it. You
	-+can use it too, but we suggest you first think carefully about whether
	-+this license or the ordinary General Public License is the better
	-+strategy to use in any particular case, based on the explanations below.
	-+
	-+ When we speak of free software, we are referring to freedom of use,
	-+not price. Our General Public Licenses are designed to make sure that
	-+you have the freedom to distribute copies of free software (and charge
	-+for this service if you wish); that you receive source code or can get
	-+it if you want it; that you can change the software and use pieces of
	-+it in new free programs; and that you are informed that you can do
	-+these things.
	-+
	-+ To protect your rights, we need to make restrictions that forbid
	-+distributors to deny you these rights or to ask you to surrender these
	-+rights. These restrictions translate to certain responsibilities for
	-+you if you distribute copies of the library or if you modify it.
	-+
	-+ For example, if you distribute copies of the library, whether gratis
	-+or for a fee, you must give the recipients all the rights that we gave
	-+you. You must make sure that they, too, receive or can get the source
	-+code. If you link other code with the library, you must provide
	-+complete object files to the recipients, so that they can relink them
	-+with the library after making changes to the library and recompiling
	-+it. And you must show them these terms so they know their rights.
	-+
	-+ We protect your rights with a two-step method: (1) we copyright the
	-+library, and (2) we offer you this license, which gives you legal
	-+permission to copy, distribute and/or modify the library.
	-+
	-+ To protect each distributor, we want to make it very clear that
	-+there is no warranty for the free library. Also, if the library is
	-+modified by someone else and passed on, the recipients should know
	-+that what they have is not the original version, so that the original
	-+author's reputation will not be affected by problems that might be
	-+introduced by others.
	-+
	-+ Finally, software patents pose a constant threat to the existence of
	-+any free program. We wish to make sure that a company cannot
	-+effectively restrict the users of a free program by obtaining a
	-+restrictive license from a patent holder. Therefore, we insist that
	-+any patent license obtained for a version of the library must be
	-+consistent with the full freedom of use specified in this license.
	-+
	-+ Most GNU software, including some libraries, is covered by the
	-+ordinary GNU General Public License. This license, the GNU Lesser
	-+General Public License, applies to certain designated libraries, and
	-+is quite different from the ordinary General Public License. We use
	-+this license for certain libraries in order to permit linking those
	-+libraries into non-free programs.
	-+
	-+ When a program is linked with a library, whether statically or using
	-+a shared library, the combination of the two is legally speaking a
	-+combined work, a derivative of the original library. The ordinary
	-+General Public License therefore permits such linking only if the
	-+entire combination fits its criteria of freedom. The Lesser General
	-+Public License permits more lax criteria for linking other code with
	-+the library.
	-+
	-+ We call this license the "Lesser" General Public License because it
	-+does Less to protect the user's freedom than the ordinary General
	-+Public License. It also provides other free software developers Less
	-+of an advantage over competing non-free programs. These disadvantages
	-+are the reason we use the ordinary General Public License for many
	-+libraries. However, the Lesser license provides advantages in certain
	-+special circumstances.
	-+
	-+ For example, on rare occasions, there may be a special need to
	-+encourage the widest possible use of a certain library, so that it becomes
	-+a de-facto standard. To achieve this, non-free programs must be
	-+allowed to use the library. A more frequent case is that a free
	-+library does the same job as widely used non-free libraries. In this
	-+case, there is little to gain by limiting the free library to free
	-+software only, so we use the Lesser General Public License.
	-+
	-+ In other cases, permission to use a particular library in non-free
	-+programs enables a greater number of people to use a large body of
	-+free software. For example, permission to use the GNU C Library in
	-+non-free programs enables many more people to use the whole GNU
	-+operating system, as well as its variant, the GNU/Linux operating
	-+system.
	-+
	-+ Although the Lesser General Public License is Less protective of the
	-+users' freedom, it does ensure that the user of a program that is
	-+linked with the Library has the freedom and the wherewithal to run
	-+that program using a modified version of the Library.
	-+
	-+ The precise terms and conditions for copying, distribution and
	-+modification follow. Pay close attention to the difference between a
	-+"work based on the library" and a "work that uses the library". The
	-+former contains code derived from the library, whereas the latter must
	-+be combined with the library in order to run.
	-+
	-+ GNU LESSER GENERAL PUBLIC LICENSE
	-+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
	-+
	-+ 0. This License Agreement applies to any software library or other
	-+program which contains a notice placed by the copyright holder or
	-+other authorized party saying it may be distributed under the terms of
	-+this Lesser General Public License (also called "this License").
	-+Each licensee is addressed as "you".
	-+
	-+ A "library" means a collection of software functions and/or data
	-+prepared so as to be conveniently linked with application programs
	-+(which use some of those functions and data) to form executables.
	-+
	-+ The "Library", below, refers to any such software library or work
	-+which has been distributed under these terms. A "work based on the
	-+Library" means either the Library or any derivative work under
	-+copyright law: that is to say, a work containing the Library or a
	-+portion of it, either verbatim or with modifications and/or translated
	-+straightforwardly into another language. (Hereinafter, translation is
	-+included without limitation in the term "modification".)
	-+
	-+ "Source code" for a work means the preferred form of the work for
	-+making modifications to it. For a library, complete source code means
	-+all the source code for all modules it contains, plus any associated
	-+interface definition files, plus the scripts used to control compilation
	-+and installation of the library.
	-+
	-+ Activities other than copying, distribution and modification are not
	-+covered by this License; they are outside its scope. The act of
	-+running a program using the Library is not restricted, and output from
	-+such a program is covered only if its contents constitute a work based
	-+on the Library (independent of the use of the Library in a tool for
	-+writing it). Whether that is true depends on what the Library does
	-+and what the program that uses the Library does.
	-+
	-+ 1. You may copy and distribute verbatim copies of the Library's
	-+complete source code as you receive it, in any medium, provided that
	-+you conspicuously and appropriately publish on each copy an
	-+appropriate copyright notice and disclaimer of warranty; keep intact
	-+all the notices that refer to this License and to the absence of any
	-+warranty; and distribute a copy of this License along with the
	-+Library.
	-+
	-+ You may charge a fee for the physical act of transferring a copy,
	-+and you may at your option offer warranty protection in exchange for a
	-+fee.
	-+
	-+ 2. You may modify your copy or copies of the Library or any portion
	-+of it, thus forming a work based on the Library, and copy and
	-+distribute such modifications or work under the terms of Section 1
	-+above, provided that you also meet all of these conditions:
	-+
	-+ a) The modified work must itself be a software library.
	-+
	-+ b) You must cause the files modified to carry prominent notices
	-+ stating that you changed the files and the date of any change.
	-+
	-+ c) You must cause the whole of the work to be licensed at no
	-+ charge to all third parties under the terms of this License.
	-+
	-+ d) If a facility in the modified Library refers to a function or a
	-+ table of data to be supplied by an application program that uses
	-+ the facility, other than as an argument passed when the facility
	-+ is invoked, then you must make a good faith effort to ensure that,
	-+ in the event an application does not supply such function or
	-+ table, the facility still operates, and performs whatever part of
	-+ its purpose remains meaningful.
	-+
	-+ (For example, a function in a library to compute square roots has
	-+ a purpose that is entirely well-defined independent of the
	-+ application. Therefore, Subsection 2d requires that any
	-+ application-supplied function or table used by this function must
	-+ be optional: if the application does not supply it, the square
	-+ root function must still compute square roots.)
	-+
	-+These requirements apply to the modified work as a whole. If
	-+identifiable sections of that work are not derived from the Library,
	-+and can be reasonably considered independent and separate works in
	-+themselves, then this License, and its terms, do not apply to those
	-+sections when you distribute them as separate works. But when you
	-+distribute the same sections as part of a whole which is a work based
	-+on the Library, the distribution of the whole must be on the terms of
	-+this License, whose permissions for other licensees extend to the
	-+entire whole, and thus to each and every part regardless of who wrote
	-+it.
	-+
	-+Thus, it is not the intent of this section to claim rights or contest
	-+your rights to work written entirely by you; rather, the intent is to
	-+exercise the right to control the distribution of derivative or
	-+collective works based on the Library.
	-+
	-+In addition, mere aggregation of another work not based on the Library
	-+with the Library (or with a work based on the Library) on a volume of
	-+a storage or distribution medium does not bring the other work under
	-+the scope of this License.
	-+
	-+ 3. You may opt to apply the terms of the ordinary GNU General Public
	-+License instead of this License to a given copy of the Library. To do
	-+this, you must alter all the notices that refer to this License, so
	-+that they refer to the ordinary GNU General Public License, version 2,
	-+instead of to this License. (If a newer version than version 2 of the
	-+ordinary GNU General Public License has appeared, then you can specify
	-+that version instead if you wish.) Do not make any other change in
	-+these notices.
	-+
	-+ Once this change is made in a given copy, it is irreversible for
	-+that copy, so the ordinary GNU General Public License applies to all
	-+subsequent copies and derivative works made from that copy.
	-+
	-+ This option is useful when you wish to copy part of the code of
	-+the Library into a program that is not a library.
	-+
	-+ 4. You may copy and distribute the Library (or a portion or
	-+derivative of it, under Section 2) in object code or executable form
	-+under the terms of Sections 1 and 2 above provided that you accompany
	-+it with the complete corresponding machine-readable source code, which
	-+must be distributed under the terms of Sections 1 and 2 above on a
	-+medium customarily used for software interchange.
	-+
	-+ If distribution of object code is made by offering access to copy
	-+from a designated place, then offering equivalent access to copy the
	-+source code from the same place satisfies the requirement to
	-+distribute the source code, even though third parties are not
	-+compelled to copy the source along with the object code.
	-+
	-+ 5. A program that contains no derivative of any portion of the
	-+Library, but is designed to work with the Library by being compiled or
	-+linked with it, is called a "work that uses the Library". Such a
	-+work, in isolation, is not a derivative work of the Library, and
	-+therefore falls outside the scope of this License.
	-+
	-+ However, linking a "work that uses the Library" with the Library
	-+creates an executable that is a derivative of the Library (because it
	-+contains portions of the Library), rather than a "work that uses the
	-+library". The executable is therefore covered by this License.
	-+Section 6 states terms for distribution of such executables.
	-+
	-+ When a "work that uses the Library" uses material from a header file
	-+that is part of the Library, the object code for the work may be a
	-+derivative work of the Library even though the source code is not.
	-+Whether this is true is especially significant if the work can be
	-+linked without the Library, or if the work is itself a library. The
	-+threshold for this to be true is not precisely defined by law.
	-+
	-+ If such an object file uses only numerical parameters, data
	-+structure layouts and accessors, and small macros and small inline
	-+functions (ten lines or less in length), then the use of the object
	-+file is unrestricted, regardless of whether it is legally a derivative
	-+work. (Executables containing this object code plus portions of the
	-+Library will still fall under Section 6.)
	-+
	-+ Otherwise, if the work is a derivative of the Library, you may
	-+distribute the object code for the work under the terms of Section 6.
	-+Any executables containing that work also fall under Section 6,
	-+whether or not they are linked directly with the Library itself.
	-+
	-+ 6. As an exception to the Sections above, you may also combine or
	-+link a "work that uses the Library" with the Library to produce a
	-+work containing portions of the Library, and distribute that work
	-+under terms of your choice, provided that the terms permit
	-+modification of the work for the customer's own use and reverse
	-+engineering for debugging such modifications.
	-+
	-+ You must give prominent notice with each copy of the work that the
	-+Library is used in it and that the Library and its use are covered by
	-+this License. You must supply a copy of this License. If the work
	-+during execution displays copyright notices, you must include the
	-+copyright notice for the Library among them, as well as a reference
	-+directing the user to the copy of this License. Also, you must do one
	-+of these things:
	-+
	-+ a) Accompany the work with the complete corresponding
	-+ machine-readable source code for the Library including whatever
	-+ changes were used in the work (which must be distributed under
	-+ Sections 1 and 2 above); and, if the work is an executable linked
	-+ with the Library, with the complete machine-readable "work that
	-+ uses the Library", as object code and/or source code, so that the
	-+ user can modify the Library and then relink to produce a modified
	-+ executable containing the modified Library. (It is understood
	-+ that the user who changes the contents of definitions files in the
	-+ Library will not necessarily be able to recompile the application
	-+ to use the modified definitions.)
	-+
	-+ b) Use a suitable shared library mechanism for linking with the
	-+ Library. A suitable mechanism is one that (1) uses at run time a
	-+ copy of the library already present on the user's computer system,
	-+ rather than copying library functions into the executable, and (2)
	-+ will operate properly with a modified version of the library, if
	-+ the user installs one, as long as the modified version is
	-+ interface-compatible with the version that the work was made with.
	-+
	-+ c) Accompany the work with a written offer, valid for at
	-+ least three years, to give the same user the materials
	-+ specified in Subsection 6a, above, for a charge no more
	-+ than the cost of performing this distribution.
	-+
	-+ d) If distribution of the work is made by offering access to copy
	-+ from a designated place, offer equivalent access to copy the above
	-+ specified materials from the same place.
	-+
	-+ e) Verify that the user has already received a copy of these
	-+ materials or that you have already sent this user a copy.
	-+
	-+ For an executable, the required form of the "work that uses the
	-+Library" must include any data and utility programs needed for
	-+reproducing the executable from it. However, as a special exception,
	-+the materials to be distributed need not include anything that is
	-+normally distributed (in either source or binary form) with the major
	-+components (compiler, kernel, and so on) of the operating system on
	-+which the executable runs, unless that component itself accompanies
	-+the executable.
	-+
	-+ It may happen that this requirement contradicts the license
	-+restrictions of other proprietary libraries that do not normally
	-+accompany the operating system. Such a contradiction means you cannot
	-+use both them and the Library together in an executable that you
	-+distribute.
	-+
	-+ 7. You may place library facilities that are a work based on the
	-+Library side-by-side in a single library together with other library
	-+facilities not covered by this License, and distribute such a combined
	-+library, provided that the separate distribution of the work based on
	-+the Library and of the other library facilities is otherwise
	-+permitted, and provided that you do these two things:
	-+
	-+ a) Accompany the combined library with a copy of the same work
	-+ based on the Library, uncombined with any other library
	-+ facilities. This must be distributed under the terms of the
	-+ Sections above.
	-+
	-+ b) Give prominent notice with the combined library of the fact
	-+ that part of it is a work based on the Library, and explaining
	-+ where to find the accompanying uncombined form of the same work.
	-+
	-+ 8. You may not copy, modify, sublicense, link with, or distribute
	-+the Library except as expressly provided under this License. Any
	-+attempt otherwise to copy, modify, sublicense, link with, or
	-+distribute the Library is void, and will automatically terminate your
	-+rights under this License. However, parties who have received copies,
	-+or rights, from you under this License will not have their licenses
	-+terminated so long as such parties remain in full compliance.
	-+
	-+ 9. You are not required to accept this License, since you have not
	-+signed it. However, nothing else grants you permission to modify or
	-+distribute the Library or its derivative works. These actions are
	-+prohibited by law if you do not accept this License. Therefore, by
	-+modifying or distributing the Library (or any work based on the
	-+Library), you indicate your acceptance of this License to do so, and
	-+all its terms and conditions for copying, distributing or modifying
	-+the Library or works based on it.
	-+
	-+ 10. Each time you redistribute the Library (or any work based on the
	-+Library), the recipient automatically receives a license from the
	-+original licensor to copy, distribute, link with or modify the Library
	-+subject to these terms and conditions. You may not impose any further
	-+restrictions on the recipients' exercise of the rights granted herein.
	-+You are not responsible for enforcing compliance by third parties with
	-+this License.
	-+
	-+ 11. If, as a consequence of a court judgment or allegation of patent
	-+infringement or for any other reason (not limited to patent issues),
	-+conditions are imposed on you (whether by court order, agreement or
	-+otherwise) that contradict the conditions of this License, they do not
	-+excuse you from the conditions of this License. If you cannot
	-+distribute so as to satisfy simultaneously your obligations under this
	-+License and any other pertinent obligations, then as a consequence you
	-+may not distribute the Library at all. For example, if a patent
	-+license would not permit royalty-free redistribution of the Library by
	-+all those who receive copies directly or indirectly through you, then
	-+the only way you could satisfy both it and this License would be to
	-+refrain entirely from distribution of the Library.
	-+
	-+If any portion of this section is held invalid or unenforceable under any
	-+particular circumstance, the balance of the section is intended to apply,
	-+and the section as a whole is intended to apply in other circumstances.
	-+
	-+It is not the purpose of this section to induce you to infringe any
	-+patents or other property right claims or to contest validity of any
	-+such claims; this section has the sole purpose of protecting the
	-+integrity of the free software distribution system which is
	-+implemented by public license practices. Many people have made
	-+generous contributions to the wide range of software distributed
	-+through that system in reliance on consistent application of that
	-+system; it is up to the author/donor to decide if he or she is willing
	-+to distribute software through any other system and a licensee cannot
	-+impose that choice.
	-+
	-+This section is intended to make thoroughly clear what is believed to
	-+be a consequence of the rest of this License.
	-+
	-+ 12. If the distribution and/or use of the Library is restricted in
	-+certain countries either by patents or by copyrighted interfaces, the
	-+original copyright holder who places the Library under this License may add
	-+an explicit geographical distribution limitation excluding those countries,
	-+so that distribution is permitted only in or among countries not thus
	-+excluded. In such case, this License incorporates the limitation as if
	-+written in the body of this License.
	-+
	-+ 13. The Free Software Foundation may publish revised and/or new
	-+versions of the Lesser General Public License from time to time.
	-+Such new versions will be similar in spirit to the present version,
	-+but may differ in detail to address new problems or concerns.
	-+
	-+Each version is given a distinguishing version number. If the Library
	-+specifies a version number of this License which applies to it and
	-+"any later version", you have the option of following the terms and
	-+conditions either of that version or of any later version published by
	-+the Free Software Foundation. If the Library does not specify a
	-+license version number, you may choose any version ever published by
	-+the Free Software Foundation.
	-+
	-+ 14. If you wish to incorporate parts of the Library into other free
	-+programs whose distribution conditions are incompatible with these,
	-+write to the author to ask for permission. For software which is
	-+copyrighted by the Free Software Foundation, write to the Free
	-+Software Foundation; we sometimes make exceptions for this. Our
	-+decision will be guided by the two goals of preserving the free status
	-+of all derivatives of our free software and of promoting the sharing
	-+and reuse of software generally.
	-+
	-+ NO WARRANTY
	-+
	-+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
	-+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
	-+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
	-+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
	-+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
	-+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
	-+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
	-+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
	-+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
	-+
	-+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
	-+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
	-+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
	-+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
	-+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
	-+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
	-+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
	-+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
	-+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
	-+DAMAGES.
	-+
	-+ END OF TERMS AND CONDITIONS
	-+
	-+ How to Apply These Terms to Your New Libraries
	-+
	-+ If you develop a new library, and you want it to be of the greatest
	-+possible use to the public, we recommend making it free software that
	-+everyone can redistribute and change. You can do so by permitting
	-+redistribution under these terms (or, alternatively, under the terms of the
	-+ordinary General Public License).
	-+
	-+ To apply these terms, attach the following notices to the library. It is
	-+safest to attach them to the start of each source file to most effectively
	-+convey the exclusion of warranty; and each file should have at least the
	-+"copyright" line and a pointer to where the full notice is found.
	-+
	-+ <one line to give the library's name and a brief idea of what it does.>

	-+/**
	-+ * @ingroup libavc
	-+ * @defgroup lavc_encdec send/receive encoding and decoding API overview
	-+ * @{
	-+ *
	-+ * The avcodec_send_packet()/avcodec_receive_frame()/avcodec_send_frame()/
	-+ * avcodec_receive_packet() functions provide an encode/decode API, which
	-+ * decouples input and output.
	-+ *
	-+ * The API is very similar for encoding/decoding and audio/video, and works as
	-+ * follows:
	-+ * - Set up and open the AVCodecContext as usual.
	-+ * - Send valid input:
	-+ * - For decoding, call avcodec_send_packet() to give the decoder raw
	-+ * compressed data in an AVPacket.
	-+ * - For encoding, call avcodec_send_frame() to give the encoder an AVFrame
	-+ * containing uncompressed audio or video.
	-+ * In both cases, it is recommended that AVPackets and AVFrames are
	-+ * refcounted, or libavcodec might have to copy the input data. (libavformat
	-+ * always returns refcounted AVPackets, and av_frame_get_buffer() allocates
	-+ * refcounted AVFrames.)
	-+ * - Receive output in a loop. Periodically call one of the avcodec_receive_*()
	-+ * functions and process their output:
	-+ * - For decoding, call avcodec_receive_frame(). On success, it will return
	-+ * an AVFrame containing uncompressed audio or video data.
	-+ * - For encoding, call avcodec_receive_packet(). On success, it will return
	-+ * an AVPacket with a compressed frame.
	-+ * Repeat this call until it returns AVERROR(EAGAIN) or an error. The
	-+ * AVERROR(EAGAIN) return value means that new input data is required to
	-+ * return new output. In this case, continue with sending input. For each
	-+ * input frame/packet, the codec will typically return 1 output frame/packet,
	-+ * but it can also be 0 or more than 1.
	-+ *
	-+ * At the beginning of decoding or encoding, the codec might accept multiple
	-+ * input frames/packets without returning a frame, until its internal buffers
	-+ * are filled. This situation is handled transparently if you follow the steps
	-+ * outlined above.
	-+ *
	-+ * In theory, sending input can result in EAGAIN - this should happen only if
	-+ * not all output was received. You can use this to structure alternative decode
	-+ * or encode loops other than the one suggested above. For example, you could
	-+ * try sending new input on each iteration, and try to receive output if that
	-+ * returns EAGAIN.
	-+ *
	-+ * End of stream situations. These require "flushing" (aka draining) the codec,
	-+ * as the codec might buffer multiple frames or packets internally for
	-+ * performance or out of necessity (consider B-frames).
	-+ * This is handled as follows:
	-+ * - Instead of valid input, send NULL to the avcodec_send_packet() (decoding)
	-+ * or avcodec_send_frame() (encoding) functions. This will enter draining
	-+ * mode.
	-+ * - Call avcodec_receive_frame() (decoding) or avcodec_receive_packet()
	-+ * (encoding) in a loop until AVERROR_EOF is returned. The functions will
	-+ * not return AVERROR(EAGAIN), unless you forgot to enter draining mode.
	-+ * - Before decoding can be resumed again, the codec has to be reset with
	-+ * avcodec_flush_buffers().
	-+ *
	-+ * Using the API as outlined above is highly recommended. But it is also
	-+ * possible to call functions outside of this rigid schema. For example, you can
	-+ * call avcodec_send_packet() repeatedly without calling
	-+ * avcodec_receive_frame(). In this case, avcodec_send_packet() will succeed
	-+ * until the codec's internal buffer has been filled up (which is typically of
	-+ * size 1 per output frame, after initial input), and then reject input with
	-+ * AVERROR(EAGAIN). Once it starts rejecting input, you have no choice but to
	-+ * read at least some output.
	-+ *
	-+ * Not all codecs will follow a rigid and predictable dataflow; the only
	-+ * guarantee is that an AVERROR(EAGAIN) return value on a send/receive call on
	-+ * one end implies that a receive/send call on the other end will succeed, or
	-+ * at least will not fail with AVERROR(EAGAIN). In general, no codec will
	-+ * permit unlimited buffering of input or output.
	-+ *
	-+ * This API replaces the following legacy functions:
	-+ * - avcodec_decode_video2() and avcodec_decode_audio4():
	-+ * Use avcodec_send_packet() to feed input to the decoder, then use
	-+ * avcodec_receive_frame() to receive decoded frames after each packet.
	-+ * Unlike with the old video decoding API, multiple frames might result from
	-+ * a packet. For audio, splitting the input packet into frames by partially
	-+ * decoding packets becomes transparent to the API user. You never need to
	-+ * feed an AVPacket to the API twice (unless it is rejected with AVERROR(EAGAIN) - then
	-+ * no data was read from the packet).
	-+ * Additionally, sending a flush/draining packet is required only once.
	-+ * - avcodec_encode_video2()/avcodec_encode_audio2():
	-+ * Use avcodec_send_frame() to feed input to the encoder, then use
	-+ * avcodec_receive_packet() to receive encoded packets.
	-+ * Providing user-allocated buffers for avcodec_receive_packet() is not
	-+ * possible.
	-+ * - The new API does not handle subtitles yet.
	-+ *
	-+ * Mixing new and old function calls on the same AVCodecContext is not allowed,
	-+ * and will result in undefined behavior.
	-+ *
	-+ * Some codecs might require using the new API; using the old API will return
	-+ * an error when calling it. All codecs support the new API.
	-+ *
	-+ * A codec is not allowed to return AVERROR(EAGAIN) for both sending and receiving. This
	-+ * would be an invalid state, which could put the codec user into an endless
	-+ * loop. The API has no concept of time either: it cannot happen that trying to
	-+ * do avcodec_send_packet() results in AVERROR(EAGAIN), but a repeated call 1 second
	-+ * later accepts the packet (with no other receive/flush API calls involved).
	-+ * The API is a strict state machine, and the passage of time is not supposed
	-+ * to influence it. Some timing-dependent behavior might still be deemed
	-+ * acceptable in certain cases. But it must never result in both send/receive
	-+ * returning EAGAIN at the same time at any point. It must also absolutely be
	-+ * avoided that the current state is "unstable" and can "flip-flop" between
	-+ * the send/receive APIs allowing progress. For example, it's not allowed that
	-+ * the codec randomly decides that it actually wants to consume a packet now
	-+ * instead of returning a frame, after it just returned AVERROR(EAGAIN) on an
	-+ * avcodec_send_packet() call.

	-+ * there may be a buffer per each data plane or anything in between. What
	-+ * this means is, you may set however many entries in buf[] you feel necessary.
	-+ * Each buffer must be reference-counted using the AVBuffer API (see description
	-+ * of buf[] below).
	-+ *
	-+ * The following fields will be set in the frame before this callback is
	-+ * called:
	-+ * - format
	-+ * - width, height (video only)
	-+ * - sample_rate, channel_layout, nb_samples (audio only)
	-+ * Their values may differ from the corresponding values in
	-+ * AVCodecContext. This callback must use the frame values, not the codec
	-+ * context values, to calculate the required buffer size.
	-+ *
	-+ * This callback must fill the following fields in the frame:
	-+ * - data[]
	-+ * - linesize[]
	-+ * - extended_data:
	-+ * * if the data is planar audio with more than 8 channels, then this
	-+ * callback must allocate and fill extended_data to contain all pointers
	-+ * to all data planes. data[] must hold as many pointers as it can.
	-+ * extended_data must be allocated with av_malloc() and will be freed in
	-+ * av_frame_unref().
	-+ * * otherwise extended_data must point to data
	-+ * - buf[] must contain one or more pointers to AVBufferRef structures. Each of
	-+ * the frame's data and extended_data pointers must be contained in these. That
	-+ * is, one AVBufferRef for each allocated chunk of memory, not necessarily one
	-+ * AVBufferRef per data[] entry. See: av_buffer_create(), av_buffer_alloc(),
	-+ * and av_buffer_ref().
	-+ * - extended_buf and nb_extended_buf must be allocated with av_malloc() by
	-+ * this callback and filled with the extra buffers if there are more
	-+ * buffers than buf[] can hold. extended_buf will be freed in
	-+ * av_frame_unref().
	-+ *
	-+ * If AV_CODEC_CAP_DR1 is not set then get_buffer2() must call
	-+ * avcodec_default_get_buffer2() instead of providing buffers allocated by
	-+ * some other means.
	-+ *
	-+ * Each data plane must be aligned to the maximum required by the target
	-+ * CPU.
	-+ *
	-+ * @see avcodec_default_get_buffer2()
	-+ *
	-+ * Video:
	-+ *
	-+ * If AV_GET_BUFFER_FLAG_REF is set in flags then the frame may be reused
	-+ * (read and/or written to if it is writable) later by libavcodec.
	-+ *
	-+ * avcodec_align_dimensions2() should be used to find the required width and
	-+ * height, as they normally need to be rounded up to the next multiple of 16.
	-+ *
	-+ * Some decoders do not support linesizes changing between frames.
	-+ *
	-+ * If frame multithreading is used and thread_safe_callbacks is set,
	-+ * this callback may be called from a different thread, but not from more
	-+ * than one at once. Does not need to be reentrant.

	-+ * AVFrame.nb_samples prior to calling get_buffer2(). The decoder may,
	-+ * however, utilize only part of the buffer by setting AVFrame.nb_samples
	-+ * to a smaller value in the output frame.
	-+ *
	-+ * As a convenience, av_samples_get_buffer_size() and
	-+ * av_samples_fill_arrays() in libavutil may be used by custom get_buffer2()
	-+ * functions to find the required data size and to fill data pointers and
	-+ * linesize. In AVFrame.linesize, only linesize[0] may be set for audio
	-+ * since all planes must be the same size.

	-+ * Create and return a AVHWFramesContext with values adequate for hardware
	-+ * decoding. This is meant to get called from the get_format callback, and is
	-+ * a helper for preparing a AVHWFramesContext for AVCodecContext.hw_frames_ctx.
	-+ * This API is for decoding with certain hardware acceleration modes/APIs only.
	-+ *
	-+ * The returned AVHWFramesContext is not initialized. The caller must do this
	-+ * with av_hwframe_ctx_init().
	-+ *
	-+ * Calling this function is not a requirement, but makes it simpler to avoid
	-+ * codec or hardware API specific details when manually allocating frames.
	-+ *
	-+ * Alternatively to this, an API user can set AVCodecContext.hw_device_ctx,
	-+ * which sets up AVCodecContext.hw_frames_ctx fully automatically, and makes
	-+ * it unnecessary to call this function or having to care about
	-+ * AVHWFramesContext initialization at all.
	-+ *
	-+ * There are a number of requirements for calling this function:
	-+ *
	-+ * - It must be called from get_format with the same avctx parameter that was
	-+ * passed to get_format. Calling it outside of get_format is not allowed, and
	-+ * can trigger undefined behavior.
	-+ * - The function is not always supported (see description of return values).
	-+ * Even if this function returns successfully, hwaccel initialization could
	-+ * fail later. (The degree to which implementations check whether the stream
	-+ * is actually supported varies. Some do this check only after the user's
	-+ * get_format callback returns.)
	-+ * - The hw_pix_fmt must be one of the choices suggested by get_format. If the
	-+ * user decides to use a AVHWFramesContext prepared with this API function,
	-+ * the user must return the same hw_pix_fmt from get_format.
	-+ * - The device_ref passed to this function must support the given hw_pix_fmt.
	-+ * - After calling this API function, it is the user's responsibility to
	-+ * initialize the AVHWFramesContext (returned by the out_frames_ref parameter),
	-+ * and to set AVCodecContext.hw_frames_ctx to it. If done, this must be done
	-+ * before returning from get_format (this is implied by the normal
	-+ * AVCodecContext.hw_frames_ctx API rules).
	-+ * - The AVHWFramesContext parameters may change every time time get_format is
	-+ * called. Also, AVCodecContext.hw_frames_ctx is reset before get_format. So
	-+ * you are inherently required to go through this process again on every
	-+ * get_format call.
	-+ * - It is perfectly possible to call this function without actually using
	-+ * the resulting AVHWFramesContext. One use-case might be trying to reuse a
	-+ * previously initialized AVHWFramesContext, and calling this API function
	-+ * only to test whether the required frame parameters have changed.
	-+ * - Fields that use dynamically allocated values of any kind must not be set
	-+ * by the user unless setting them is explicitly allowed by the documentation.
	-+ * If the user sets AVHWFramesContext.free and AVHWFramesContext.user_opaque,
	-+ * the new free callback must call the potentially set previous free callback.
	-+ * This API call may set any dynamically allocated fields, including the free
	-+ * callback.
	-+ *
	-+ * The function will set at least the following fields on AVHWFramesContext
	-+ * (potentially more, depending on hwaccel API):
	-+ *
	-+ * - All fields set by av_hwframe_ctx_alloc().
	-+ * - Set the format field to hw_pix_fmt.
	-+ * - Set the sw_format field to the most suited and most versatile format. (An
	-+ * implication is that this will prefer generic formats over opaque formats
	-+ * with arbitrary restrictions, if possible.)
	-+ * - Set the width/height fields to the coded frame size, rounded up to the
	-+ * API-specific minimum alignment.
	-+ * - Only _if_ the hwaccel requires a pre-allocated pool: set the initial_pool_size
	-+ * field to the number of maximum reference surfaces possible with the codec,
	-+ * plus 1 surface for the user to work (meaning the user can safely reference
	-+ * at most 1 decoded surface at a time), plus additional buffering introduced
	-+ * by frame threading. If the hwaccel does not require pre-allocation, the
	-+ * field is left to 0, and the decoder will allocate new surfaces on demand
	-+ * during decoding.
	-+ * - Possibly AVHWFramesContext.hwctx fields, depending on the underlying
	-+ * hardware API.
	-+ *
	-+ * Essentially, out_frames_ref returns the same as av_hwframe_ctx_alloc(), but
	-+ * with basic frame parameters set.
	-+ *
	-+ * The function is stateless, and does not change the AVCodecContext or the
	-+ * device_ref AVHWDeviceContext.
	-+ *
	-+ * @param avctx The context which is currently calling get_format, and which
	-+ * implicitly contains all state needed for filling the returned
	-+ * AVHWFramesContext properly.
	-+ * @param device_ref A reference to the AVHWDeviceContext describing the device
	-+ * which will be used by the hardware decoder.
	-+ * @param hw_pix_fmt The hwaccel format you are going to return from get_format.
	-+ * @param out_frames_ref On success, set to a reference to an _uninitialized_
	-+ * AVHWFramesContext, created from the given device_ref.
	-+ * Fields will be set to values required for decoding.
	-+ * Not changed if an error is returned.
	-+ * @return zero on success, a negative value on error. The following error codes
	-+ * have special semantics:
	-+ * AVERROR(ENOENT): the decoder does not support this functionality. Setup
	-+ * is always manual, or it is a decoder which does not
	-+ * support setting AVCodecContext.hw_frames_ctx at all,
	-+ * or it is a software format.
	-+ * AVERROR(EINVAL): it is known that hardware decoding is not supported for
	-+ * this configuration, or the device_ref is not supported
	-+ * for the hwaccel referenced by hw_pix_fmt.

	-+ * @li @ref lavfi "libavfilter" graph-based frame editing library

	-+ * @li @ref lpp "libpostproc" post processing library
	-+ * @li @ref libsws "libswscale" color conversion and scaling library
	-+ *
	-+ * @section ffmpeg_versioning Versioning and compatibility
	-+ *
	-+ * Each of the FFmpeg libraries contains a version.h header, which defines a
	-+ * major, minor and micro version number with the
	-+ * <em>LIBRARYNAME_VERSION_{MAJOR,MINOR,MICRO}</em> macros. The major version
	-+ * number is incremented with backward incompatible changes - e.g. removing
	-+ * parts of the public API, reordering public struct members, etc. The minor
	-+ * version number is incremented for backward compatible API changes or major
	-+ * new features - e.g. adding a new public function or a new decoder. The micro
	-+ * version number is incremented for smaller changes that a calling program
	-+ * might still want to check for - e.g. changing behavior in a previously
	-+ * unspecified situation.
	-+ *
	-+ * FFmpeg guarantees backward API and ABI compatibility for each library as long
	-+ * as its major version number is unchanged. This means that no public symbols
	-+ * will be removed or renamed. Types and names of the public struct members and
	-+ * values of public macros and enums will remain the same (unless they were
	-+ * explicitly declared as not part of the public API). Documented behavior will
	-+ * not change.
	-+ *
	-+ * In other words, any correct program that works with a given FFmpeg snapshot
	-+ * should work just as well without any changes with any later snapshot with the
	-+ * same major versions. This applies to both rebuilding the program against new
	-+ * FFmpeg versions or to replacing the dynamic FFmpeg libraries that a program
	-+ * links against.
	-+ *
	-+ * However, new public symbols may be added and new members may be appended to
	-+ * public structs whose size is not part of public ABI (most public structs in
	-+ * FFmpeg). New macros and enum values may be added. Behavior in undocumented
	-+ * situations may change slightly (and be documented). All those are accompanied
	-+ * by an entry in doc/APIchanges and incrementing either the minor or micro
	-+ * version number.

	-+ * AVBuffer is an API for reference-counted data buffers.
	-+ *
	-+ * There are two core objects in this API -- AVBuffer and AVBufferRef. AVBuffer
	-+ * represents the data buffer itself; it is opaque and not meant to be accessed
	-+ * by the caller directly, but only through AVBufferRef. However, the caller may
	-+ * e.g. compare two AVBuffer pointers to check whether two different references
	-+ * are describing the same data buffer. AVBufferRef represents a single
	-+ * reference to an AVBuffer and it is the object that may be manipulated by the
	-+ * caller directly.
	-+ *
	-+ * There are two functions provided for creating a new AVBuffer with a single
	-+ * reference -- av_buffer_alloc() to just allocate a new buffer, and
	-+ * av_buffer_create() to wrap an existing array in an AVBuffer. From an existing
	-+ * reference, additional references may be created with av_buffer_ref().
	-+ * Use av_buffer_unref() to free a reference (this will automatically free the
	-+ * data once all the references are freed).
	-+ *
	-+ * The convention throughout this API and the rest of FFmpeg is such that the
	-+ * buffer is considered writable if there exists only one reference to it (and
	-+ * it has not been marked as read-only). The av_buffer_is_writable() function is
	-+ * provided to check whether this is true and av_buffer_make_writable() will
	-+ * automatically create a new writable buffer when necessary.
	-+ * Of course nothing prevents the calling code from violating this convention,
	-+ * however that is safe only when all the existing references are under its
	-+ * control.
	-+ *
	-+ * @note Referencing and unreferencing the buffers is thread-safe and thus
	-+ * may be done from multiple threads simultaneously without any need for
	-+ * additional locking.
	-+ *
	-+ * @note Two different references to the same buffer can point to different
	-+ * parts of the buffer (i.e. their AVBufferRef.data will not be equal).

	-+ *
	-+ * The first system stores pointers to values in a block of dynamically
	-+ * allocated memory. Since only pointers are stored, the function does not need
	-+ * to know the size of the type. Both av_dynarray_add() and

	-+ * Pixel format.
	-+ *
	-+ * @note
	-+ * AV_PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
	-+ * color is put together as:
	-+ * (A << 24) \| (R << 16) \| (G << 8) \| B
	-+ * This is stored as BGRA on little-endian CPU architectures and ARGB on
	-+ * big-endian CPUs.
	-+ *
	-+ * @par
	-+ * When the pixel format is palettized RGB32 (AV_PIX_FMT_PAL8), the palettized
	-+ * image data is stored in AVFrame.data[0]. The palette is transported in
	-+ * AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
	-+ * formatted the same as in AV_PIX_FMT_RGB32 described above (i.e., it is
	-+ * also endian-specific). Note also that the individual RGB32 palette
	-+ * components stored in AVFrame.data[1] should be in the range 0..255.
	-+ * This is important as many custom PAL8 video codecs that were designed
	-+ * to run on the IBM VGA graphics adapter use 6-bit palette components.
	-+ *
	-+ * @par
	-+ * For all the 8 bits per pixel formats, an RGB32 palette is in data[1] like
	-+ * for pal8. This palette is filled in automatically by the function
	-+ * allocating the picture.

	-+ * The FFmpeg libraries follow a versioning sheme very similar to
	-+ * Semantic Versioning (http://semver.org/)
	-+ * The difference is that the component called PATCH is called MICRO in FFmpeg
	-+ * and its value is reset to 100 instead of 0 to keep it above or equal to 100.
	-+ * Also we do not increase MICRO for every bugfix or change in git master.
	-+ *
	-+ * Prior to FFmpeg 3.2 point releases did not change any lib version number to
	-+ * avoid aliassing different git master checkouts.
	-+ * Starting with FFmpeg 3.2, the released library versions will occupy
	-+ * a separate MAJOR.MINOR that is not used on the master development branch.
	-+ * That is if we branch a release of master 55.10.123 we will bump to 55.11.100
	-+ * for the release and master will continue at 55.12.100 after it. Each new
	-+ * point release will then bump the MICRO improving the usefulness of the lib
	-+ * versions.

	-commit 68124009fc5a
	-Author: Nicholas Nethercote <nnethercote@mozilla.com>
	-Date: Fri Feb 16 17:54:16 2018 +1100
	-
	- Bug 1438678 - Pass early prefs via shared memory instead of the command line. r=bobowen,jld,glandium.
	-
	- This patch replaces the large -intPrefs/-boolPrefs/-stringPrefs flags with
	- a short-lived, anonymous, shared memory segment that is used to pass the early
	- prefs.
	-
	- Removing the bloat from the command line is nice, but more important is the
	- fact that this will let us pass more prefs at content process start-up, which
	- will allow us to remove the early/late prefs split (bug 1436911).
	-
	- Although this mechanism is only used for prefs, it's conceivable that it could
	- be used for other data that must be received very early by children, and for
	- which the command line isn't ideal.
	-
	- Notable details:
	-
	- - Much of the patch deals with the various platform-specific ways of passing
	- handles/fds to children.
	-
	- - Linux and Mac: we use a fixed fd (8) in combination with the new
	- GeckoChildProcessHost::AddFdToRemap() function (which ensures the child
	- won't close the fd).
	-
	- - Android: like Linux and Mac, but the handles get passed via "parcels" and
	- we use the new SetPrefsFd() function instead of the fixed fd.
	-
	- - Windows: there is no need to duplicate the handle because Windows handles
	- are system-wide. But we do use the new
	- GeckoChildProcessHost::AddHandleToShare() function to add it to the list of
	- inheritable handles. We also ensure that list is processed on all paths
	- (MOZ_SANDBOX with sandbox, MOZ_SANDBOX without sandbox, non-MOZ_SANDBOX) so
	- that the handles are marked as inheritable. The handle is passed via the
	- -prefsHandle flag.
	-
	- The -prefsLen flag is used on all platforms to indicate the size of the
	- shared memory segment.
	-
	- - The patch also moves the serialization/deserialization of the prefs in/out of
	- the shared memory into libpref, which is a better spot for it. (This means
	- Preferences::MustSendToContentProcesses() can be removed.)

	-commit 6b81d0b99f20
	-Author: Nicholas Nethercote <nnethercote@mozilla.com>
	-Date: Thu Mar 8 15:47:24 2018 +1100
	-
	- Bug 1436911 - Avoid the early/late prefs split. r=glandium
	-
	- All prefs that need to be sent to a new content process are now put into the
	- shared memory segment, and they are identified by the pref name instead of an
	- index into a list. The old IPC used at process startup (in XPCOMInitData) is
	- removed.
	-
	- Benefits:
	-
	- - It removes the need for the early prefs list
	- (dom/ipc/ContentProcesses.{h,cpp}) and the associated checking, which is ugly
	- and often trips people up (e.g. bug 1432979, bug 1439406).
	-
	- - Using prefnames instead of indices fixes some fragility (fixing bug 1419432).
	-
	- - It fixes the problem of early prefs being installed as unlocked default
	- values even if they are locked and/or have user values.

	-+ //
	-+ // No whitespace is tolerated between tokens. <type> must match the types of

	-+ //
	-+ // The serialization is text-based, rather than binary, for the following
	-+ // reasons.
	-+ //
	-+ // - The size difference wouldn't be much different between text-based and
	-+ // binary. Most of the space is for strings (pref names and string pref
	-+ // values), which would be the same in both styles. And other differences
	-+ // would be minimal, e.g. small integers are shorter in text but long
	-+ // integers are longer in text.
	-+ //
	-+ // - Likewise, speed differences should be negligible.
