[YouTube] Auto-generated playlist/mix: null on getName() #2895

Iamdeadlyz · 2019-12-27T04:16:27Z

I carefully read the contribution guidelines and agree to them.
I checked if the issue/feature exists in the latest version.
I did use the incredible bugreport to markdown converter to paste bug reports.

Exception

User Action: requested playlist
Request: https://www.youtube.com/watch?v=2kZVEUGLgy4&list=RDdoEcQv1wlsI&index=2, opened with video_player
Content Language: PH
Service: YouTube
Version: 0.17.4
OS: Linux Android 8.0.0 - 26

How To Reproduce:

Open an external link which is the playlist (like this one)
Select NewPipe in the prompt "Complete action using"
Select show info/video player/popup player/background player (if you press download, it will say unsupported url)
Then the guru meditation error report will show

That is an auto-generated playlist which has no valid uploader. The crash is fixed in version 0.18.0 (should be on F-Droid soon).

Iamdeadlyz · 2019-12-28T06:10:40Z

Hi,
It looks like the issue is still not fixed at version 0.18.0

TobiGr · 2019-12-28T11:12:49Z

Hm. that's bad.

XiangRongLin · 2020-02-02T12:17:48Z

The problem is that auto-generated playlists don't have a "youtube.com/playlist?list=playlistID" url. But the linkhandler converts

https://www.youtube.com/watch?v=2kZVEUGLgy4&list=RDdoEcQv1wlsI&index=2

to

https://www.youtube.com/playlist?list=RDdoEcQv1wlsI

So the extractor would need to differenciate between user-generated playlists and auto-generated ones and in the case of auto-generated ones, extract them from the first link and not the second one.

It seems that:

User-generated playlist ids start with "PL"
Auto-generated playlist ids start with "RD" followed by the video id of the first video in the playlist.

XiangRongLin · 2020-02-02T13:54:10Z

I threw together a way to handle it like described above. After some quality control i'll open a PR.

PeterHindes · 2020-03-02T15:57:12Z

Just got fixed in 18.6. Close the issue

XiangRongLin · 2020-03-02T18:29:23Z

It throws a different error now, but still crashes when i open the link from the original crash report

If auto-generated playlist means a "Mix", then yes, those aren't supported yet and sorry for closing.

XiangRongLin · 2020-03-02T19:02:29Z

In this context it should be "Mix".
My PR should fix this, i just need to update it for the new user-agent and etc.

PeterHindes · 2020-03-04T18:43:04Z

Oh this is about support for YouTube Mix'es. You should change the title.
