MP4Box create thumbnail

Fri Nov 22, 2013 5:39 pm

I have a video from the camera board but would like to create a screenshot (thumbnail) after 3 seconds. I can not seem to find a way with mp4box. I tried ffmpeg but it looks like it first has to loop through all frames of the first 3 seconds which is really slow. How can I get a video thumbnail?

I created a quick workaround because ffmpeg is really slow and has to process all frames up to the specified frame. It's dirty but for those who like to do the same thing:

I convert the second of the video i would like to get the thumbnail from with MP4Box (which is really fast) and then run ffmpeg to grap the first frame of that video.
