Andreas Rheinhardt 5ecf5b93dd avcodec/mpegvideo: Don't check for draw_horiz_band 
Some parts of mpegvideo.c behave differently depending
upon whether AVCodecContext.draw_horiz_band is set or not.
This differing behaviour makes lots of FATE tests fail
and leads to garbage output, although setting this callback
is not supposed to change the output at all.

These checks have been added in commits
3994623df2 and
b68ab2609c. The commit messages
do not contain a real reason for adding the checks and it is
indeed a mystery to me. But removing these checks fixes
the FATE tests when one adds an (empty) draw_horiz_band
when using a codec that claims to support it.

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.

Documentation
