I'm not entirely sure but I'm confident there are some muxing tools on windows, there are as well
FFmpgeg CLI commands too.

Yes you need ffmpeg. The command is along the lines of
ffmpeg -fflags +genpts -framerate 30 -i video.264 -f s16le -ar 48000 -ac 2 -i audio.raw -c:v h264 -c:a aac output.mp4
to convert just the video you can do ffmpeg -r 30 -i video.264 -vcodec copy video.mp4

@exelix11 Thanks.
Its working.
I converted a file of about 3 minutes.
The only problem is that the video is finished faster than the sound.

i'm not sure. Maybe ffmpeg got the framerate or sample rate wrong. Try converting audio and video separately and then mux them together.
This save to file thing was intended mostly for debug, should probably look into implementing and actual mp4 file writer.

Release 5.1 replaced video.h264/audio.raw file exporting with proper mp4 recording, this shouldn't be an issue anymore.
