I want to use 3 seconds clip which has been cut. However, the dataset loading method of my model is openCV. Then, I find that the center frame is not in the middle but at the 3/4 of the total frames.
How to solve this problem?
The following line of code contains the wrong key for reading the action ID from the ava_train_v2.1.csv
from here
action_string = action_name[int(anno_data[idx][-1])]
However changing that to,
action_string = action_name[int(anno_data[idx][6])]
will solve the problem.
Thank for releasing this tool. Is the keyframe that is extracted in extract_keyframe.py the same as an RGB frame?
