Description

Using the latest 2024.07.25 version and already checked https://github.com/ytdl-org/youtube-dl/issues/30839, still having issue with simple command like youtube-dl https://www.youtube.com/watch?v=ab8EQZSWQOk

SamDDBS commented 1 month ago

Will ditto that i have this same issue, also version 2024.07.25. Tried downloading a playlist and got the same errors for every video it tried bugreport.txt

Haifen commented 1 month ago

Confirming the same issue, commit e1b3fa2 (AKA 2024.07.25 I guess :shrug:). Output of youtube-dl --verbose -F https://youtu.be/tSMR2Lf40X4 is attached. youtube-dl--verbose-F_https___youtu.be_tSMR2Lf40X4-output-2024073101.txt Also confirming this is a likely duplicate of #32885 (@dirkf references yt-dlt/yt-dlp#10608, which in turn references yt-dlt/yt-dlp#10611, which may be possible to merge into youtube-dl (not tried to merge from yt-dlp's extractor into youtube-dl's).

ShantanuNair commented 1 month ago

The fix is in the 2024.08.01.000109 master release.

yanmiao2 commented 1 month ago

The fix is in the 2024.08.01.000109 master release.

I'm quite confused, the link you gave points a different repo yt-dlp, isn't that a different library this (youtube-dl)?

diff.txt Attached is a patch that resolves the issue. Thanks to yt-dlp team.

Haifen commented 1 month ago

Did a quick & dirty cherry-pick of upstream, and was about to make a git-am patch of it, but @rasterfarm was quicker on the draw, and did a better merge of upstream's changes. Patch applies, merges (using Gentoo to test), and fixes the issue. Would make a pull, but don't want to take credit for @bashonly and @rasterfarm's work. Will do it if no-one else does, with full attribution.

which release is the newest without this issue ? (and as such works out of the box)

Please don't post in closed duplicate issues unless there is an enormously good reason. Otherwise I'll have to enforce that by locking such issues.

Apparently your git checkout isn't running the code that's in the listed commit: somehow an older version of one or more files is in use. Here's the nightly release built from the same commit succeeding with the same player JS:
