What would be involved in updating the profile used for web browsers to add HEVC support for Chrome since HEVC decode is now supported in 107?
When I try to stream media that is HEVC in Chrome it’s still transcoding to h264, I assume because the server isn’t aware the browser supports it now.
@kazz3r24 Even though Chrome now supports it, your graphics card and drivers must also support hardware decoding of H.265
I’ve got a 3080ti in this system with the latest Nvidia drivers.
@kazz3r24 In that case, the only thing I can think of is that you have to wait until they update Plex web as maybe Plex didn’t use the standard flags for selecting video codecs.
The update for Chrome only came out today. Plex just needs to update the profile for Chrome so the server knows the browser now supports hevc.
I was simply checking to see if this was something I could do myself quickly, who knows when Plex will get around to doing this. I’m an eager beaver.
Folks.
This will take a bit to implement.
Please give the team time to understand what they have, schedule the work, and subsequent testing thereof
EDIT: Enhancement request submitted to development team.
No problem, I know the browser just updated today - I just wanted know if it was on the horizon to get updated and wasn’t sure if it could be done with just a profile update or not.
Thank you for the info!
@ChuckPa do the client Profiles still do something?

does not do anything
Profiles are used when the device isn’t already supported by the players (Plex/web in this case)
If you had a completely new, previously unknown, browser then the profile would activate.
The Plex/web team was three steps ahead of me.
Was this supposed to be a link?
@ChuckPa how to manipulate a “known” device/client?
each browser has a built-in string which identifies it.
You can’t manipulate this.
My previous post regarding HEVC in Plex/web –
They have completed the work. It’s being tested. It will likely be released soon.
Don’t bother trying to HACK something due to impatience.
I can barely support Official some days 
No way could I ever support something ‘unofficially customized’.
I’m so excited for this change to be made! Above though, if it uses the user agent, you can change that, if that helps people in the meantime: How to Change User-Agents in Chrome, Edge, Safari & Firefox
From what I can see HEVC on Chrome won’t work on Linux until v108. Will there have to be a new release of Plex to handle it when v108 is released, or should it just work?
I’ve asked the Plex/web team. waiting for reply…

The latest Web Desktop app supports HEVC in Chromium 107+ if the browser reports support. HDR support is upto the browser implementation
It works on Chrome 109 Unstable on Linux! The video isn’t decoding properly (green lines through it) but I believe that’s a Chrome issue and Google is aware of it.
Very exciting!
Works like a charm under Windows 10!
Even with HEVC HDR and proper local tonemap.
Only on my Chromebook it still transcodes to H264 (in Chrome and in Plex Android). 
Everyone is waiting for v 108 for Linux.
Aaaand its gone again. HEVC stopped working in Chrome 107.
