Have you tried adding (silent) audio to video 2 and trying your join
operation again? You could use `anullsrc':
This is what I am trying to do, but wasn't able to accomplish the first step
which is adding a silent audio to my video using anullsrc.
I came up with the following command after doing some search and also based
on Michael's command sample:
Ffmpeg -i video.mp4 -f lavfi -i anullsrc=r=48000:cl=2 -c:v copy -c:a aac
-shortest output.mp4
At the end of the console output I get the following:
Press [q] to stop, [?] for help
[aac @ 0000023281941140] Unsupported channel layout "1 channels (FR)"
try to replace cl=2 by cl=stereo
Michael
