"Could not be read the video [video name]" when running "extract_features.p"

[meegoStar]

Hello, I'm running extract_features.py using the command KERAS_BACKEND=theano python -u extract_features.py -d ~/Videos/videos. Sometimes I see the program printing messages of Could not be read the video [video name], for example Could not be read the video Af_0zV79zsk, while Af_0zV79zsk.mp4 does exist under the path where I store all the downloaded videos of the ActivityNet dataset.

So my question is are those videos with this kind of messages printed still be extracted the C3D features?

As you have downloaded Af_0zV79zsk.mp4 video, it should still be there, but what shouldn't be is the Af_0zV79zsk.npy file at the extracted features directory.

At this line it shows that when the video can not be read, it jumps to the next one without saving the extracted features.
