I was using ffmpeg to generate some images from a video. Now I read that I shouldn't use ffmpeg longer and use avconv from libav instead. So I tried to do the same thing with avconv.
The ffmpeg is looking like this:
ffmpeg -ss 1000 -t 5 -i 'test.mp4' -s '120*90' -r 10 out%2d.bmp
Same with avconv:
avconv -ss 1000 -t 5 -i 'test.mp4' -s '120*90' -r 10 out%2d.bmp
ffmpeg needs less than one second to finish. Avconv about 90 seconds for the same task. Is this usual or do I need to change some things to work with avconv?
