Andreas Rheinhardt cbe23e40ae truehd_core: Correct output size 
If truehd_core strips Atmos data away, three parts of the output differ
in size compared to the input access unit: a) The major_sync_info block
if the extra_channel_meaning_data is present, as the newly written
output never contains said block; b) the substream_directory (because
entries relating to discarded substreams are discarded, too); and c)
the actual substream data. b) and c) have already been taken into account
when choosing the size of the output packet, but a) has been forgotten.

This is also the reason behind the end of the output buffer having been
uninitialized until 801d78f0. The workaround added in said commit has
been removed, too.

  • 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.
