How to block youtube ads?

I yould like to block youtube ads.
I've already searched the web. And found this input:

Sadly the domains youtube / google uses for ads changed since last year.
They seem to use:
r6---sn-a5mekn7y.googlevideo.com
r4---sn-4g5edned.googlevideo.com
r2---sn-4g5ednsl.googlevideo.com

But when I use the expression:
^r[0-9]+---[a-z]+-[a-za-z0-9]+.googlevideo.com
The videos do not load anymore

Expected Behaviour:

pihole blocks youtube ads inside videos as ublock origin does at the desktop PC.

Actual Behaviour:

Youtube videos don't run at all.

There are many discussions about this topic. It comes down to that they are using the same servers for ads and content so distinguishing them isn't possible (it may have been in the past).

Search the forum for numerous failed attempts to block youtube ads...

are there any new infos on this topic?

No, there are not.
