performance - A faster way to get screenshots of a video with ffmpeg -


i trying use ffmpeg screenshots of video @ given rate, works want, except fact has process entire video (which can take long time) , use ton of cpu resources grab few frames.

here ffmpeg command using screenshots: 

ffmpeg -i "$videoname" -vf fps=$enterfps img%03d.jpg

is there way make faster?

you can try select filter instead.

ffmpeg -i input_video -vf "select=between(t\,10\,20)" -vsync vfr output_image%04d.png

this output frames in between 10-20 time interval. can refer here more information.
