Hi. I have an interesting case. I need to extract sound from multiple
input files, combine those video files into one, and then re-insert
the audio into the combined video file.
Unfortunately I need to do them in this order. Extract sounds, then
combine the input videos, then add sound back to the resulting video.
Can someone help me the first step?
I tried this:
$ ffmpeg -i resized/360_0233.MP4 -i resized/360_0234.MP4 -i
resized/360_0235.MP4 -vn -map 0:a tmpsound.mp3
Not tested, but I think it should work with the concat filter:
ffmpeg -i resized/360_0233.MP4 -i resized/360_0234.MP4 -i
resized/360_0235.MP4 -lavfi [0][1][2]concat=n=3:v=0:a=1 -y tmpsound.mp3
