James Almer 757367e068 avformat/demux: extract extradata from packets when context update is requested 
If the demuxer doesn't set extradata in the stream's codecpar, a
need_context_update request will delete the previously extracted extradata in
the stream's internal AVCodecContext.
As we can't ensure the old extradata is valid for the stream in its post
context update request state, try to get extradata from the new packet instead
of attempting to preserve the old in some form.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
