Demux .mp4 (video+audio) to 2 separate files (video.mp4) + (audio.mp4)

[kalemvar1]

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.

ffmpeg -hide_banner -i "input.mp4" -c:v copy -map 0:0 "video.mp4" -c:a copy -map 0:1 "audio.m4a"

Use clever Ffmpeg-GUI.
Load your mp4, click main, click extract video stream, click extract video.
If done, you have your videostream only in a new mp4 file.
Then click multiplex, uncheck all streams except the desired audio stream, click multiplex.
If done, you have the desired audiostream in a new mp4 file.
