Any FFmpeg gurus here? need help with command generating thunbs. - GoFuckYourself.com

So I have this command that will make 4 thumbs for each video. The problem is thumb starts at certain position and makes 4 frames back to back. How would I space them out lets say 30 seconds apart or say make 4 thumbs for each video equally spaced.

This:

for i in *.mp4; do ffmpeg -i "$i" -an -ss 00:00:30 -an -r 1 -vframes 4 -s 160x120 -y `basename $i .mp4`_%d.jpg; done

Thanks

easiest way is divide total frames by the number of thumbs you want, then grab those frames in a loop with ffmpeg.

i export 200 per video.

for i in *.mp4; do ffmpeg -i "$i" -vcodec mjpeg -vf fps=1/30 -s 160x120 "$i_%d.jpg"; done;

fyi it was the 2nd result on google.

https://trac.ffmpeg.org/wiki/Create%...%20the%20video

you should probably learn to use google if you are coding.

You should learn how to keep you mouth shut if you have nothing to say. My problem was about generating and naming thumbs in a loop not how to generate 3 frames from 1 file.

Go look for attention elsewhere now. We solved the ffmeg issue. Get lost.

i dont know about crackhead, but she was definitely a ho

(i was born before crack)

the hilarious thing to me is someone getting butthurt about being trolled on a forum built for trolling. your low level of emotional intelligence is forever recorded in gfy history. its a good thing you hide your identity

i'm a very generous and helpful guy. i found this for you. i think it will help..
