Creating thumbnails with FFmpeg
3 janvier 2012, par Calin-Andrei BurloiuI am using FFmpeg to extract thumbnails from specific positions of video files.
I found on the web two approaches to do this :
-
With
-ss
(seek) parameter before-i
(input) parameter :ffmpeg -y -ss $SEEK_POINT -i input.ogv -vcodec mjpeg -vframes 1 -an -s 120x90 -f rawvideo output.jpg
-
With
-ss
(seek) parameter after-i
(input) parameter :ffmpeg -y -i input.ogv -vcodec mjpeg -ss $SEEK_POINT -vframes 1 -an -s 120x90 -f rawvideo output.jpg
The first method generates a bad thumbnail with gray spots, but works very fast. The error returned is
[theora @ 0x8097240] vp3: first frame not a keyframe
.The second method always works but show an error which cause the extraction to take a lot of time. This amount of time is not fixed and it depends on the seek point as I noticed. Sometimes it takes a few seconds and other times several minutes to extract a thumbnail. I get the error
