I have multiple JPEG Sequences
and i want to output them as output.mp4
One single shot works fine like that:
ffmpeg -i "/mydir/A/preview.%04d.jpg" output.mp4
And it works as well with a txt file containing the files.
file '/mydir/A/preview.%04d.jpg' file '/mydir/B/preview.%04d.jpg'
ffmpeg -f concat -i mylist.txt output.mp4
But i would like to generate a command on the fly without outputting something extra on disc!
PS: i am linux
