Make GPU acceleration work, 1080p YouTube videos play under Linux and I'll consider it.

I've been playing 1080p (and higher, like 1440p) Youtube videos on Linux without issues.

If you have the CPU power to waste then maybe yeah, it plays, but it's not possible with my hardware.

[nacs]

My video is definitely hardware (GPU) accelerated. If you don’t have working hardware acceleration in Firefox for videos/WebGL, there’s something wrong with your setup, it’s not a FF problem.

I and many others in this thread have no issue with this in FF.

[Avamander]

"It works on my machine", really?!

There's nothing wrong with my setup, there are numerous issues open on FF Issue tracker about this s*.

Have you set `layers.acceleration.force-enabled` to `true` in about:config?

It may help.

[Avamander]

Last I tried enabling that FF just started freezing randomly after, WebGL was still much slower than Chrome's and had artifacts, YouTube still didn't play 1080p smoothly. It just didn't work and reading the issue tracker they have no proper plans to fix all the acceleration issues under Linux either.

That is too bad. What distro are you on? What version of mesa are you using?

[Avamander]

Kubuntu, latest mesa available from repositories. I'm monitoring the issues, will try again if some of them get resolved.

Good luck, for what it is worth, WebRender is being enabled on Linux. https://bugzilla.mozilla.org/show_bug.cgi?id=1543862

Try the latest version. I don’t have any issue with Youtube 1080p videos.

had 4k video work just fine under linux in firefox for as long as youtube has had 4k videos

[Avamander]

I can't call stuttering video in firefox for as long as youtube has had 1080p videos, "works just fine".
