FFMPEG: How to convert M2V Video with two single WAV tracks (stereo) to MP4?

How can I create a MP4 file with ffmpeg out of a M2V-Video-File and two WAV-Files (one file for the right audio channel and one for the left audio channel)?

Solution

  • try this:

    ffmpeg -i video.m2v -i audio1.wav -i audio2.wav -c:v copy -c:a aac -map 0:v:0 -filter_complex "[1:a][2:a]join=inputs=2:channel_layout=stereo[a]" -map "[a]" output.mp4

    I believe mp4 files cannot contain PCM audio, hence converting to aac.
