As I known, ffmpeg is mainly used for transcode video/audio, and
player, e.g., mplayer, is mainly decode and play a video/audio. If your
"decode" means "transcode", read the documentation "-map" option for
your "decode multi-channel video at the same time":

And, if you need help on this list, the best is post your command line
and uncut console output.
