avconv to convert avi frames to single images
Hi,
I have some small avi movies which contain each about 20 frames which are shown at about 2 frames per second. I would like to convert these movies into individual images, so 20 images per movie. I have been trying to do this with 'avconc', but do not manage to do so. Right now I use
avconv -i test.avi -f image2 image-%03d.jpg
which gives the following error:
avconv -i test.avi -f image2 image-%03d.jpg
avconv version 0.8.3-6:0.8.3-7, Copyright (c) 2000-2012 the Libav developers

Any help is very much appreciated!
