How to map the video name in csv to file path in unzipped files?

[I-E-E-E]

e.g. how to translate ---_iRTHryQ_13_0to241.mp4 in OpenVidHD.csv to a valid file path?

---_iRTHryQ_13_0to241.mp4 is the name of the video. For example, you can read the video by:
video_path = os.path.join(dataset_path, video_name)
vframes, aframes, info = torchvision.io.read_video(filename=video_path, pts_unit="sec", output_format="TCHW")
