I'm trying to merge a few video files through
mkvmerge but I get the following error after running
mkvmerge -o '/home/videos/marged/new.mp4' '/home/videos/intro.mp4' \+ 'old.mp4' \+ '/home/videos/intro.mp4'
Error: The track number 1 from the file 'old.mp4' cannot be appended to the track number 1 from the file '/home/videos/intro.mp4'. The sample rate of the two audio tracks is different: 44100 and 22050
Is there a way to force this? If not how can I change the audio to the same rate as
old.mp4 in ffmpeg for
