Anton Khirnov cfbf10412f tests/fate/filter-audio: add a test for handling more than 64 channels
The test constructs 66 sine waves of different frequencies and joins
them into a 7th order ambisonic layout with extra non-diegetic
stereo. The channels are then shifted circularly with channelmap and
separated into individual streams for muxing with channelsplit.

Note that the last step is necessary because swr is not capable of
interleaving planar to packed for more than 64 channels, which would be
necessary to mux such a stream as PCM.

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 means to alter decoded audio and video through a directed graph of connected 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
