how to set gstreamer finish time while jpeg image capture?

Question

I used below gstreamer command for capturing total 10 images every 1 second.

But the command finished before 10 images...

gst-launch-1.0 -e v4l2src device=/dev/video0 num-buffers=10 ! queue ! videorate ! image/jpeg,framerate=1/1 ! multifilesink index=0 location=frame%04d.jpg sync=true async=false

how can i set running time or finishing time??

Answer 1

It depends on your camera framerate. For example, if your camera runs at 10 fps, as you set v4l2src to stop after 10 frames, it will run for one second.

You would set num-buffers to framerate * duration, so 100 frames for 10 seconds at 10 fps.
