Depending on the calculation it may be easier/more intuitive to
use framerate:
ffmpeg -i input -filter:v framerate=1/10 out-%d.jpg
will create one image every ten secs.
Hi
I dont need every x seconds one image ;)
I need it like (dirty example) at youporn.
Every videos (not depending which filelength) has exact 9 thumbnails.
Linear division over the length.
So the 5th thumbnail is in the middle of the video.
Best Regards
Chris
