Andreas Rheinhardt fdcd3dcf2e avcodec/vc1: Don't check for AVCodecContext.codec 
This check has been added in c617bed34f,
merging ee769c6a7c to fix
a possible segfault if AVCodecContext.codec is not set
as it may be during parsing. While this fixes the segfault,
it has the unfortunate side effect that it makes the output
of the parser dependent on whether a decoder is set (and
ultimately available). The fix later applied in
5d2be71b9e does not have this
downside and makes checking AVCodecContext.codec superfluous.
So remove this check.

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.
