Some YouTube videos do not show download progress in the web UI.

[YamatoRyou]

Version: 3.0.5 (Docker)

Here's a example https://www.youtube.com/watch?v=tUFJPUQb7NA *This video has a maximum resolution of 76804320.**

Importing the above link in the Web UI does not have any visual feedback (including download progress), but by observing the container log you can find that it is already in the downloading state.

it also happens on a 8 hours long 1080p video, file size might be the reason

@YamatoRyou could you retest it with the version 3.0.6?

Still invisible (as of this test, the Docker image labeled "latest" was last updated about 2 hours ago).

Hello!

It seems an issue from yt-dlp itself. Every 8k video I've tried results in this.

yt-dlp version: v2024.04.09

[eslym]

isn't that dns problem?

[marcopeocchi]

you're right. I'm changing dns

edit: changing dns solved the problem

[marcopeocchi]

Ok, I understand now the issue: in version 3.0.5 the metadata of the download were not set properly. With no metadata (title, image, etc.) the download was filtered by the UI, resulting in no entry on screen.

In 3.0.6 this was fixed, if no metadata is found the download it's still kept.

I'm asking you to retest it in the latest docker image.

It looks like the fault has gone away (as of this test, the Docker image labeled "latest" was last updated about 6 hours ago).
