How to use FFmpeg

Question

I\'m trying to extract frames from a video and I\'ve picked ffmpeg ( tell me if you know something better ) for this task.

I\'ve downloaded its source and don\'t know

Answer 1

If you only want use ffmpeg you should just get a build and not the source itself.

To extract a frame from a video use the following command line:

ffmpeg -i input.avi -r 1 -f image2 -s 120x96 images%05d.png

Where input.avi is your video, 120x96 the dimension of the output image. There are a lot of options you can use to specify the exact frame in the movie, but that would definetely be too much to show here. Take a look at this page to get a more detailed description.
