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
