Frame Count Mismatch During Frame Extraction from Videos

[huyanh995]

Hi,

Description:
I've encountered inconsistencies in the number of extracted frames when comparing different extraction methods with the pre-extracted frames provided by the dataset.

For example P01_04.MP4:

• Pre-extracted frames (provided): 6320 frames
• Using torchvision.io.read_video: 6308 frames
• Using ffmpeg with 60fps (as suggested in EPIC-KITCHENS 55 repo): 6314 frames
  ffmpeg -i "P01_04.MP4" -vf "scale=-2:256" -q:v 4 -r 60 "P01_04/frame_%010d.jpg"

Could you share the exact method used to extract the pre-extracted frames provided in the dataset?

Note: I have already checked the md5 hash of tar file with md5.csv and it's matched.

Thank you very much!

Thank you for your help

One more question. I'm having issues with P09_06.MP4 - downloaded it on 3 different machines but can't match the hash in md5.csv.

My MD5 hash is 53052418c6fea04ee82d74ff829fe78e

Could you please verify this file and confirm the correct hash value?

Thank you.
