[p]play returns an error, but using the [p]play with a search query does not. Please make this consistant.
In this image, the bot says WebM is not supported

In this image, the bot starts playing the video.

They both use the same link!

[p]play
Audio
Either block both or accept both. Maybe check if the livestream is not live anymore and if so, just play it like a normal video.
Both have different results
[p]play https://www.youtube.com/watch?v=FLM2U9bAlgU returns error
[p]play rooler does not
Currently running the newest build

Okay, before I dismiss this I would like to ask you a few questions. Go to the main server and ping me me in there @Draper#6666
Update, had a chat with Drapersniper. Seems to be a deeper issue in the backend. He will hunt for the poor bastard that has to fix the issue.
Hi, sorry this took a while but this was being determined in our audio backend and not through code that we write/control ourselves. This will be working for you now with Red 3.4.2 (to be released soon(tm)), but playing the direct link will display a long track time (106751991167:07:12:56). I'm going to be closing this as the playback portion will be functional with our Red 3.4.2 update and the audio backend that's included with that version, but I am keeping that long track time in mind and will also work with others on getting that resolved at some point as well.
Edit: This should be fully resolved with Red 3.4.3 and the 1132 build of our Lavalink.jar.
