[FFmpeg-devel] question on mosiac video issues -shortest

When using the param -shortest appears to have no impact on my ffmpeg
command using multiple inputs as source. One is a looping slate video that
stops and it seems to stop all other inputs when making a mp4 archive. Any
suggestions on what I can do as using another param or output syntax?

3 examples of syntax i used


-shortest  videos/output.mp4 -y

cmd = """
