I have a video which runs for 30 minutes at the rate of 60 fps. I need to extract the frame every 10 second. For example: 10s(600th frame),20s(1200th frame),30s(1800th frame) so on..... I looked through the internet I can get the info about how to read, write video and extract frame but did not get the info about exactly what I am looking for. Your help will be appreciated!
