I made a new r= parameter, like:
https://kister.net/mpl/yt2m3u8?v=mhJRzQsLZGg,r=360p
Things wont work if you specify a resolution that Youtube isn't streaming in, so I also made a middle-man that can show you the available resolutions. In a regular web browser, use the detail= parameter like https://kister.net/mpl/yt2m3u8?detail=mhJRzQsLZGg -- it'll print out which are available.
https://kister.net/mpl/yt2m3u8?w=mhJRzQsLZGg,r=360p not work.
but https://kister.net/mpl/yt2m3u8?w=mhJRzQsLZGg working.
Advice?
change the w= to v=
all these options are making it not so easy 
EDIT: oh, you are using this in VLC.
use &r=360p instead of ,r=360p
i will try on some softwares, but what i do is i test every stream on vlc and than on others.
Are link is pernament?
I've found they're "permanent" so long as YouTube's vid_id in the URL doesn't change. Some livestreams do go down after a few weeks (or months) and then return later with a new URL. When that happens, those vid_id's would have to be updated in the URL in your Custom Channels setup.
In the past with HLStube I'd found some livestreams that were accessible via "www.youtube.com/channel/CHANNEL_ID/live" but that didn't always work, and wasn't available for all channels. Now I can't seem to even find any examples of such to test with the Kister Method, so this point may be moot.
Huh?
You're already watching one of them.
https://www.youtube.com/@twit/live
That /live redirect only works for youtube accounts that have a single Live stream.
Doesn't work on others like SkyNews, SpaceX, etc. that have more than one.
Ah, thanks. Must be my mistake, or the syntax changed, because I was trying: http://www.youtube.com/channel/@twit/live
Regardless, I don't think the Kister Method can work with the corrected https://www.youtube.com/@twit/live address either anyway, as the Kister Method's syntax specifically requires a vid_id in the URL.
Cool, thanks. It’s working great.
Now I dare you to make it easier a create a gui on your site with selectable variables and settings! 
is there a possibility to add something and streams to be automatically mute?
Strange, i try streams on omxplayer on raspberry pi, it worked for a couple of minutes, and then just turn off.
No
I never knew about that. I obviously have no experience with it, but it should be super simple to support. I added a hack to make @ usernames work just like vid_id, except the script will automatically add /live to the end.

Brand new code, I don't know how it will behave when twit is not streaming/live.
Some of the confusion stems from a different thread where @Steffi_333 had been trying to address an issue with FAR more frequent timeouts (like every few hours.) That thread was closed as it wasn't about Channels DVR. Youtube to m3u - #3 by Stefi_333
Still not about Channels DVR. As you were told by one of the developers and administrator of this forum, this is off-topic, and your questions about other applications belong elsewhere. Please don't get this thread locked too 
Wow, this is awesome! Thanks so much. I'll give it a shot and see how it goes. Super cool, I'm learning a lot from this and appreciate you sharing.
I 
The Kister Method.
Nice! It works.
Ok, its not about Channels Dvr, i understand.
I dont get my threat locked, my opinion is that is you.
But ok, i understand, thanks!!!
Any ideas why this request to twit is failing?

Just as a data point, I just tested and my TWiT livestream via the Kister Method is working fine. Hmm.
I don't have anything that I can think of that would generate any 429. And I don't relay any error that youtube sends. Do you happen to use a proxy server or VPN ?
Can we do 4k streams? It seems it tops at 1080p for this video
