Andreas Rheinhardt 99c191151a truehd_core: Disable 16-channel presentation 
The most serious bit of the substream_info header field (in a mayor sync
packet) indicates whether a 16-channel presentation is present in the
bitstream. If set, the extended_substream_info header field contains
information about the 16-channel presentation. This presentation always
uses substream 3, a substream that is discarded by truehd_core. So
substream_info needs to be changed to no longer indicate the presence
of a 16-channel presentation in order for truehd_core's output to be
consistent. This is implemented in this commit.

This change also makes MediaInfo no longer display the presence of Atmos
in the output of truehd_core.

Also, set the (now irrelevant) extended_substream_info field to zero as
this seems to be the common value for ordinary TrueHD.

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.
