[FFmpeg-user] Suggestion for improvement, Video in reverse order

[Michael Koch]

Hi all,

I'd like to make a suggestion for improvement. It's easy to make a video 
from many pictures, but it's difficult to make a video which runs in 
reverse order. I propose a new parameter "-number_decrease" which tells 
ffmpeg to decrease the file number, instead of increasing it.

Example:
ffmpeg -start_number 100 -number_decrease -i 'IMG-%03d.jpg' out.mkv

In this example the file names would be IMG-100.jpg  IMG-099.jpg 
IMG-098.jpg  and so on.
