+Subject: [PATCH] Fix build with ffmpeg 6
+
+This doesn't attempt to replace deprecated functions, it only replaces
+functions that are gone (avcodec_encode_[audio|video]2) with
+straight-forward replacement code.
+
+It fixes the build with the latest 6.0 release and still builds fine
+with ffmpeg 4.4
