Andreas Rheinhardt 2ca072e168 avcodec/vp3: Remove always-false checks 
The dimensions are only set at two places: theora_decode_header()
and vp3_decode_init(). These functions are called during init
and during dimension changes, but the latter is only supported
(and attempted) when frame threading is not active. This implies that
the dimensions of the various worker threads in
vp3_update_thread_context() always coincide, so that these checks
are dead and can be removed.

(These checks would of course need to be removed when support
for dimension changes during frame threading is implemented;
and in any case, a dimension change is not an error.)

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.
