YouTube An error occurred. Please try again later

Hello everybody,

I’m running Clear Linux now for a while and I really like it.

But I always have trouble with playing YouTube Videos. Youtube Player tells me on the most videos “An error occurred. Please try again later. (Playback ID: OHZJ78MCimHTGSs8)”

It’s possible to play some videos, but mostly I will get that error.

Also I have checked:
It seems to be ok.

Any idea how to fix it at Firefox 75.0 (64-bit) ?

Sometimes it is helpful to use another Browser like Midori, but not at all.

Thanks a lot!


This is intended. Search H.264 in the forum and install the proprietary codecs yourself.

I’ve experienced the same and, to me, it seems related to the following:
I’ve seen an issue on GitHub that has been filed as a ClearLinux’ bug but it’s not.
Youtube uses canvas and webgl for rendering and it actually re-encodes our videos into VP9.
As a matter of fact, I couldn’t test Three.js demos either as they were a mess and I thought I had problems with drivers but it is a bug in Firefox.
I did what’s described in the bug report, and it has fixed the problem on my Laptop, Intel N4000 running Mesa Intel® UHD Graphics 600 (GLK 2).
I’ve opened “about:config” in Firefox (version 75.0 64bit) and I’ve modified these two variables.

security.sandbox.content.level 2

security.sandbox.content.read_path_whitelist = /sys/devices/pci0000:00/0000:00:02.0/subsystem

Result : WebGL fixed. H264 and VP9 files playing fine.

Hope this helps.

EDIT: I was wrong on h264, I also lack the codecs but the webgl bug in firefox is confirmed (so, CleaLinux isn’t the problem).
