I know that ffmpeg is enable to extract images at any desired time interval
from a video stream. i.e the below command:
ffmpeg -i test.avi -r 1 -s WxH -f image2 test-%03d.jpeg
extract 1 second image interval from test.avi. But i dont know how to
change this command to extract just I-Frames from the stream, regardless of
the frame time position.
Can u help me to find the solution?
