what should I do?

[zhoujiawei3]

It seems that KenoVelicanstveni‘s video has some problem

[GihhArwtw]

hi @zhoujiawei3

yes, i think the error is related to unsuccessful download. Maybe you could try to use another tool to download KenoVelicanstveni‘s videos? You just need to change method in configs/download.json to yt-dlp.

[zhoujiawei3]

@GihhArwtw I have already changed to yt-dlp, as the other method doesn't work for me. I try several times to download the mini-dataset on different machines, the problem occurs on the same video KenoVelicanstveni/Qb5UT3pSxjI.mp4. And I have checked they are both 2,56,1,588,623 B. When I remove that video and adjust the json, the video2img.py can successfully run.

[zhoujiawei3]

@GihhArwtw But only extract two val video ：（. Is that right? For images to train, don't we need to change it to images?

[GihhArwtw]

no it's not right. I think it's used for debugging and I forgot to comment it out when pushing the code. Thanks for pointing this out.

[GihhArwtw]

already fixed and updated :)

[zhoujiawei3]

@GihhArwtw Thank you for your reply. However, after I made the changes here and tried to extract again, all the mp4 videos in the train set encountered an ffmpeg-related issue. None of the mp4 videos could be extracted. Since the downloaded exception.txt shows "Checking download status finished" and the video size remains the same despite multiple attempts to download, I suspect this may not be a download issue. Could it be that the 3.4.9 ffmpeg and mp4 are incompatible? I'm not sure how to resolve this problem. I would greatly appreciate any help you could provide.

[GihhArwtw]

I'll check on it. But in fact ffmpeg is used only for checking the download status and we use opencv for frame extraction, I think there might be some other problems.

[GihhArwtw]

hi @zhoujiawei3 i still need to confirm one more thing with you, though. On our server, some videos downloaded by yt-dlp are of webm format and renaming them to mp4 has caused problems before. For example, the video KenoVelicanstveni/Qb5UT3pSxjI is downloaded in webm format on our server. But according to your feedback above, it is downloaded as mp4 format on yours. So i'm wondering whether this is caused by different package version or something like that. Could you please provide more info, e.g. system (Linux/Windows), conda env and installed packages?

[zhoujiawei3]

My system is Linux. I'm not quite sure what format the video is in during the download process, but after it's completed, it's in MP4 format. I notice this difference, the 'mp4' format videos don't have '*.mp4.part' file in the folder, while the 'webm' format video has it in the folder.

[GihhArwtw]

get it. I noticed that you are using yt-dlp==2024.11.4, which is different from that in our env (yt-dlp==2024.8.6). I'm not sure if this caused the problem but I'll check on it.

also, i think *.part and *.ytdl should not exist when the download is successful. They should be removed automatically when yt-dlp finished the download. Did you happen to pause the download process?

[zhoujiawei3]

My download process don't have been interrupted manually. I suspect that perhaps the initial download failed when using multiple workers, and some fragment files were not deleted properly? I try to download the video on another server, .part and .ytdl don‘t exist in the final folder, as your words. I compared the sizes of the downloaded MP4 and WEBM files on these two server, they are identical. I guess the mp4 file occuring problem isn't related to the unsuccessful download. Maybe it's related to the version of yt-dlp, I will try it, thank you！

[GihhArwtw]

in the meantime I'm running the scripts completely from scratch on our server. If I found other problems, I'll keep you updated.

[GihhArwtw]

the mini subset download just finished on our test server. I test the video2img script and it works well. I suppose the problem is caused by the version of yt-dlp indeed. Please let us know if you encounter other issues in the following process. I'll update the requirements.txt once yt-dlp==2024.8.6 works well on your end.

[zhoujiawei3]

When I change yt-dlp==2024.8.6, the problem is solved. Thank you for your help!

[GihhArwtw]

also updated in requirements. Hope everything goes well!
