Andreas Rheinhardt eec26b5911 avformat/matroskadec: avcodec/tta: Set extradata_size to 22 
Up until c4e0e314, the seek table has been included in the tta
extradata, so that the size of said extradata was 22 (the size of a TTA1
header) + 4 * number of frames. The decoder rejected anything below a
size of 30 and so the Matroska demuxer exported 30 byte long extradata,
of which only 18 were set (it ignores a CRC-32 and simply leaves it at
0). But this is unnecessary since said commit, so reduce the size to 22.

Furthermore, replace 30 by 22 in a comment about the extradata size in
libavcodec/tta.c.

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.

Documentation

The offline documentation is available in the doc/ directory.

The online documentation is available in the main website and in the wiki.

Examples
