We have support for some ambisonics formats. Use them. How else would users know what is what? Check the number of channels? Also what about mapping families 240(?) -> 254? I thought they were reserved for ambisonics (very recently too, though they don't define any specific layouts :/). IMO this might need a new channel layout API with support for ambisonics because things are messy there as-is. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
