• Add X265 knob (default off) for X.265 (HEVC) encoding support using multimedia/x265.
  
  Example usage: (-c:a libfdk_aac needs FDK_AAC knob too)

ffmpeg -i $inputvideofile -c:a libfdk_aac -b:a 64k -c:v libx265 -x265-params crf=31 $outputfile.mkv

This can now be played back by at least ffplay (needs SDL knob),
vlc, mplayer, mpv, xine.  (and gives a nice reduction in file size.)

No objection from: multimedia@ list
