Andreas Rheinhardt c72a29df6b avcodec/cllc: Don't unnecessarily free VLC 
The Canopus Lossless decoder uses several VLCs and if initializing the
ith VLC fails, all the VLCs 0..i have been freed; the ith VLC's table is
initialized to NULL for this purpose. Yet it is totally unnecessary to
free the ith VLC table at all: ff_init_vlc_sparse() cleans up after
itself on error and if an error happens before ff_init_vlc_sparse(),
the ith VLC hasn't been touched yet and doesn't need freeing.

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.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
