[FFmpeg-devel] Please allow specific starting frame to be selected.

[Ben Hutchinson]

I have an MP4 video, and I'm trying to extract 100 frames starting from
frame number 271. As of right now I can select duration by time using -t or
by frame count by using -frames. And I can also select starting point by
time by using -ss. However, I believe that as of now there is no command
line switch to select the starting point by frame number.

PLEASE add a feature such as a command line switch like "-sf" for "starting
frame". I need to be able to select a range of video frames based entirely
on frame numbers (not time stamps).
