Description

Raiplay parser does not work, while passing directly the video file link still works smoothly.

#23040 should fix this, sadly it still hasn't been merged it seems.
It works and it always worked in my case.
I have to manually apply the patch after each youtube-dl update

[glucini]

It works perfectly. I am just wondering why it is not yet merged. Thank you for the prompt help, much appreciated.
