Parallelize Youtube video frame download using yt-dlp and cv2

[zulle]

First of all thanks for replying

@berak

(the set() is almost for free, but the following read() might have to decode maybe 100 frames manually (from the last keyframe found to desired position))

You mean, that before actually read the wanted frame it has to decode all the others from the start up to the n-th frame (with n the frame that precede the first frame that I want to download)?

@berak

if you could do the “slice some frames out of the middle” part from the downloader (maybe this ?), far more efficient i guess

Moreover if I able to implement the download_range hopefully if will cut the video using the start_time ad end_time parameters, and then I can use my extract_frames function to download continuous frames. Are you suggesting this? Or I’ve misunderstood?
