I'd like to know how should I extract frames from a video. If I use your 'multiprocess_video2frame' file and set 'gap=1' to process it, the number of frames seems usually a little bit less than the 'img_num' in annotation like 599 vs 601. And if I use ffmpeg, I set the fps as 'img_num'/20, the result is still not equal to the 'img_num'. Could you please give some advice?
