YouTube Playback issue

[mpotthoff]

I'm having trouble with a different video now. (Don't ask why it's always a pengu video 😋)
https://www.youtube.com/watch?v=ufEEfbfb3xk

I have tried it 10 times and never managed to play it completly. I got the following exception a few times when I tried to play the song (it didn't even start and just broke directly)

[sedmelluq]

Some YouTube videos use slightly different arguments in their JSON configuration. Fixed in 1.2.12.

[mpotthoff]

It still doesn't work for me. Now I get a different exception with the provided video.

I looked into the formats map and it only contains "itag", "type", "url" and "quality".

[sedmelluq]

Should be properly fixed since 1.2.13

[sedmelluq]

Not sure if there's anything I can do about socket timeout, but I added the Premature end exception to the cases where it tries to reconnect (1.2.18).

Do you have a relatively unstable connection by any chance?

[mpotthoff]

That's also what i thought first, but nope, it's running on a dedicated server and the connection of it is perfectly fine. Nothing else running on it has any problems and it only started recently with some videos :/

[mpotthoff]

Just got this again with 1.2.18 :C

What's the default connect & read timeout and is there any way to change it? I just did a small test and loaded the URL logged by lavaplayer manually with curl and it took around 5 seconds before it actually started receiving data.

[sedmelluq]

Uh, sorry about that, I didn't actually catch that exception. Maybe 1.2.19 is the charm.

The connect timeout for all HTTP connections opened is currently hardcoded to 3 seconds, so that might indeed be the issue with the read timeout (as it happens during connecting). I'll need to figure out a way to expose that setting. The latency shouldn't really be that high with a decent connection though.

[mpotthoff]

The strange thing is that it only occurs on some videos and on a different server the playback works fine. It's definetly not the connection of the server, I ran some monitoring and verified that it gets the full 1 Gbit/s. Maybe there is a bad route for some of youtube's server or some of them are overloaded. I don't know. With the bad streams I also only get around 30 kb/s when it finally starts receiving data.

[mpotthoff]

Okay. So I tried to set the connect, socket and connection-request-timeout to 10 seconds. Didn't help. Same exception after 10 seconds.

[sedmelluq]

Seems like there really is no option to play those tracks then, especially if they eventually download so slowly anyway. May I ask which hosting provider you are using?

[mpotthoff]

I'm using Hetzner from Germany.

[mpotthoff]

Okay. The problem seems to have resolved itself for now (I have no idea what changed) so I'm going to close this now. Thank you a lot for your support! You are doing a great job here :)
