Andreas Rheinhardt 8b7964f8f8 avformat/matroskaenc: Fix BlockGroup size calculation
The earlier code included the size of the BlockGroup's length field and
the EBML ID in the calculation of the size for the payload and ignored
the size of the  duration's length field. This meant that Blockgroups
corresponding to packets with size 2^(7n) - 17 - n - i, i = 0,..., n - 1,
n = 1,..., 8 (i.e. 110, 16364, 16365, 2097130..2097132, ...) were written
with length fields that are unnecessarily long.

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.
