Extract frame dynamically
on Sep 14, 2011 at 4:41:55 pm

Dear forum,

I am trying to extract frames from a movie dynamically and it has to be fast. I there a way of doing this with ffmpeg, without having to save the extracted frame on the disk and opening it in my code ?

Basically, the thing I want to do is:

seq = load(movie_file)
while(data_available(seq)):
frame = get_frame(seq)
do_stuff(frame)
go_to_next_frame(seq)
end


Any help is warmly welcome ! Thanks,

Laurent Nguyen
