Start_frm is starting from 0. What is the criterion for ending? #68

Hello there, I've fine-tuned my own dataset, and then I want to use csv files to extract features for intensive prediction. The beginning of the csv file is org_video, label, start_frm, video_id; start_frm starts from 0, so how to determine the size of the end frame? I hope to get your help, thank you very much!

You need to calculate that on your own I think. You can do that by using opencv capture FRAME_COUNT property. 

  int num_of_frames = cap.get(CV_CAP_PROP_FRAME_COUNT);

also, take a look here - might be useful https://github.com/kenshohara/3D-ResNets-PyTorch/blob/master/utils/n_frames_kinetics.py
