Description

Hello there,

A decrypted YouTube URL can lead to 403 error randomly. For example, requesting "Audio + Video" mp4 URL of YouTube video ZbZSe6N_BXs then curl test connection:

for i in {1..100}
do
   url=$(youtube-dl --get-url ZbZSe6N_BXs --format 18)
   curl -Is $url | head -n 1
done

Out of that 100 repeated tests, there are usually less than 10 tests having broken connection (HTTP/1.1 403 Forbidden). Any thoughts?

dirkf commented 1 year ago

Each YT download link has a backup server encoded in its URL. YT switches to the backup server if the server in the host part of the URL gives 403 (possibly 404 too).

yt-dl doesn't (currently) use the backup server because of program architecture. The badness of the specified host in the download link is only discoverable when actually downloading. If YT download links were tested at extraction time (which would noticeably slow down the extraction, given the large number of formats offered), their validities might have changed by the time the download is initiated. But there is (currently) no mechanism for handling this fallback at download time; in particular, the failure might be detected by an external downloader over which yt-dl has no control.

See also #30990 for a related issue where YT's CDN servers fail to be updated consistently, and a relevant maxim

There are 2 hard problems in computer science: cache invalidation, naming things, and off-by-1 errors.

dirkf commented 1 year ago

We could add each backup server link with a lower preference so that it only gets selected when explicitly requested. But that's no help when the preferred URL has been returned with --get-url to be downloaded later.

Especially https://github.com/yt-dlp/yt-dlp/issues/1986#issuecomment-1013307105.

dirkf commented 1 year ago

So perhaps a way to handle this problem, other than just sucking it up, would involve a custom downloader that understands the YT fallback server specification in the download URL? Or, as the specification is so specific, it could just be an escape in the normal downloaders?

victorbiga commented 1 year ago

I came here from duplicate ticket and not sure the above subject is exactly related, but if the issue is in regards this error after downloading few

ERROR: unable to download video data: HTTP Error 403: Forbidden

then this is somehow related to youtube rate limiting and not youtube-dl

What DID NOT WORK for me:

youtube-dl  -o '%(title)s.%(ext)s' https://www.youtube.com/playlist\?list\=PLoQKfAob6SMy9RY1IYCwBu4nFdSjc7wDI -x --audio-format "mp3" --sleep-interval 5 -r "20k"

What WORKED for me:

youtube-dl  -o '%(title)s.%(ext)s' https://www.youtube.com/playlist\?list\=PLoQKfAob6SMy9RY1IYCwBu4nFdSjc7wDI -x --audio-format "mp3" --sleep-interval 5 -r "20k"

Adding --sleep-interval 5 for 5 seconds and limiting download rate to 20KBs -r "20k solved the problem and full playlist was able to successfully download without any errors.

(I think this is a similar issue, but please let me know if this should be a new issue....)

I tried adding --sleep-interval 5 -r "20k" as was suggested by victorbiga, however I continue to get errors.

if this should be a new issue ...
[debug] yt-dlp version stable@2023.03.04 [392389b7d] (zip)
i.e. you're using the downstream fork (yt-dlp), not youtube-dl 😠 ; whatever "issue" besets you while using yt-dlp, please post about it at their own tracker 😉 ...

In the future, should you wish to post in the youtube-dl issue tracker, please first review pinned issue #30839, which specifically contains below clause:

If you were actually running yt-dlp, go there. Similarly with other forks,

FWIW, I don't see any "403" errors in your posted yt-dlp debug log; latest youtube-dl (built from master HEAD) has no issue fetching the video in your log:
