wm4 cf57cb3ae4 h264: add AVOption to set x264_build default 
This provides a generic way to the API user to deal with files that
either lack this SEI, or which have the SEI only in packets not passed
to the decoder (such as the common case of the SEI being in the very
firsat video packet, but decoding is started somewhere in the middle of
the file). Bugs like 840b41b2a643fc8f0617c0370125a19c02c6b586 make this
somewhat of a necessity.

This intentionally uses the version in the SEI instead, if any is found.

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 a mean to alter decoded Audio and Video through chain of 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.
  • ffserver is a multimedia streaming server for live broadcasts.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
