    Is there a simple way to demux a video+audio .mp4 file to 2 seperate files (video.mp4) and (audio.mp4) ?

    I've tried with mp4box and tsmuxer without success. I'm sure there a simple way to do it.

    Thanks guys

    Load the file into mkvmerge,output as file.mkv,then load the file into mkvcleaver and output video and audio,others may have different methods but this is done quickly without re-encoding.
    I think,therefore i am a hamster.
