Browser-laptop: YouTube / Netflix movie freezes a couple of seconds per minutes

[luixxiul]

Description

There is a report that YouTube video freezes a couple of seconds.

https://community.brave.com/t/youtube-freezes-some-more-details/10635?u=suguru

Three Brave versions ago the video playback freezes would last for half a second to two seconds.
Two Braves ago the freezes were dramatically reduced. Very brief freezes.
The last Brave update and the current Brave version the freezes are back to half to two seconds.

I started timing the freezes on a few videos. All from the same uploader and same resolution: 720p/60fps.
Almost like clockwork (within a few seconds) it would freeze at 1:00, 6:00, 11:00. 16:00…
At one minute then every five minutes there after…

I notice the same thing on YouTube and Netflix as well. According to the report the issue looks similar to this one https://github.com/brave/browser-laptop/issues/10094, while on this case UI is not locked up.

Steps to Reproduce

1. Watch a movie on Netflix or YouTube

Actual result:

See above.

Expected result:

The movie should not freeze.

Reproduces how often:

Consistently.

Brave Version

Further experimenting.

Same YouTube uploader as before. Same resolution 720/60.

I opened five videos by clicking the links with the middle mouse button so they open in new tabs but dont start playing.

First video freezes at:
0:28, 5:25, 10:20, 15:15. Again, first freeze, then five minutes for each one after that.

The second video was interesting:
1:02, 5:57, 10:46… Then I got an email, so I paused the video, opened the email, clicked the link in the email which opened a new tab in brave and it caused all the other YouTube videos I had open to start playing.

I paused all the other videos and kept watching the one I was on.
… 13:50, 18:36, 23:29.

Again, initial freeze, then every five minutes after that. Except for when things screwed up in the middle and time was three minutes, but then it was still every five minutes from then on.

Seeing the above happen a lot when I was playing videos from Jimmy Kimmel Live when going through the YT feature that's slated for hotfix5... Happens every 10-20 seconds.

@kjozwiak let's retest after new RC that will have #11969 in

I'm seeing this on Windows 10 on version 0.19.139. I've had videos freeze on YouTube a lot for a long time. I've switched to Edge just for YouTube.
