Jai Luthra 15b86f480a mlpenc: Working MLP/TrueHD encoder
* Multichannel support for TrueHD is experimental

    There should be downmix substreams present for 2+ channel bitstreams,
    but ffmpeg decoder doesn't need it. Will add support for this soon.

* There might be lossless check failures on LFE channels

* 32-bit sample support has been removed for now, will add it later

    While testing, some samples gave lossless check failures when enforcing
    s32. Probably this will also get solved with the LFE issues.

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.
  • ffserver is a multimedia streaming server for live broadcasts.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
