Dear FFmpeg users.
If I use multiply -ss options with the same video
ffmpeg -ss 00:00:05 -i input.mp4
-ss 00:01:05 -i input.mp4
-ss 00:03:05 -i input.mp4
-ss 00:40:05 -i input.mp4
-map 0:v -frames:v 1 out001.jpg
-map 1:v -frames:v 1 out002.jpg
-map 2:v -frames:v 1 out003.jpg
-map 3:v -frames:v 1 out004.jpg
The same video would be opened few times or it would be opened just once (for
the optimization and speed-up purpose)?
Regards,
Oleksii
