What an idiotic format. It makes no sense, and should have been converted to S32 in the demuxer, rather than plague everyone with another extremely obscure nonsense format. Why doesn't ffmpeg add S24 instead? That's an actually useful format. May cause compilation failure with old FFmpeg or Libav libs, but I don't care.
