SOLVED: "Playback failed due to a fatal player error." (Only in Firefox)

[TheDreadPirate]

In the list of codecs, you can check H264, MPEG2, and VC1.

Can you share your jellyfin logs via pastebin?

Did you switch to VAAPI? You showed the screenshot of you switching, but the log is still saying you're using QSV?

I noticed that the output of the transcode is 4K. I'm wondering if that iGPU just doesn't support transcoding to that resolution. In Firefox, go to the Settings > Playback menu (not the one in dashboard) and set the max transcode resolution to 1080p.

Ah yes sorry my bad, that was the old paste, here is the with VAAPI : https://pastebin.com/EnYYNrY4

And here is the log with max transcoding set to 1080p on firefox: https://pastebin.com/uzXx6v7B and apparently as you can see it plays on firefox although its quite choppy if you try to move around... 
The thing is on chromium browsers i can play it on 4k with no problem at all smooth as hell and even when moving around in the movie the playback is almost instant its almost as fast as playing local so the iGPU is probably capable of it since it works on edge.
Here is an image of player info from edge:


And here is one from firefox with capped transcoding at 1080p:

Hope these tell you something more.

Also here is the log with setting max transcoding to 1080p on my android device(xiaomi mi 10): https://pastebin.com/iWdjLGqg still isn't working there... even tried 360p to no avail. So no screenshot from there i still get the "Playback failed due to fatal player error"

Firefox doesn't do HEVC, period. So it is transcoding, successfully this time. But it is BARELY managing 1x speed. Because of the specs of your server, I'd recommend using Jellyfin Media Player on your PC clients, since it can direct play pretty much anything.

[altair]

Hmm, what about the mobile app? i still get the error there. I tried the Android TV app and it works there, that's weird any idea about that?
EDIT: I just found out that on the app you can Settings > Client Settings > Video player and change it to integrated player or external, instead of web player and HEVC should work on android app as well.
I tried the windows app as well plays well again. I'll probably use that or edge.

Documentation has H.265 as not supported on Firefox indeed. I didn't know HEVC is actually H.265.
Thank you so much for the help TheDreadPirate really appreciated!

Did you setup low power encoding?

https://jellyfin.org/docs/general/admini...e-on-linux

Also, since you're using a backport kernel, did you also install all the kernel header, module, and firmware packages?

My apologies for the late response, but when trying to follow the steps in the link you sent, I'm stuck on step 4.
When using sudo dmesg | grep i915
I get the following:

And when using:

sudo cat /sys/kernel/debug/dri/1/gt/uc/huc_info

And

Code:

sudo cat /sys/kernel/debug/dri/0/i915_guc_load_status
sudo cat /sys/kernel/debug/dri/0/i915_huc_load_status

I get the following:
"No such file or directory"
When using ls in the /sys/kernel/debug/dri/ I get:

Code:

lrwxrwxrwx  1 root root 0 Oct 21 00:51 0 -> 0000:03:00.0
drwxr-xr-x 16 root root 0 Oct 21 00:51 0000:03:00.0
lrwxrwxrwx  1 root root 0 Oct 21 00:51 128 -> 0000:03:00.0

Any suggestions on what I'm doing incorrectly?

Kind regards

P.S. My apologies for my incompetence.

Different distros locate the i915 status in slightly different places. On Ubuntu 24.04 with both an iGPU and Arc GPU, my Arc GPU's status is located in

/sys/kernel/debug/dri/1/gt0/uc/guc_info
/sys/kernel/debug/dri/1/gt0/uc/huc_info

Start in /sys/kernel/debug/dri, then stop through each directory one at a time after that.

Having said that, the dmesg output looks good. The above will show, essentially, the same info.

Couldn't get the cat commands to work, but I did enable low-power hardware encoding.
And the file I couldn't play before plays now.

I'll set your initial reference to the Jellyfin docs as the solution.

Thank you soo much for all the help!!
It's greatly appreciated.
Again, thank you.
