On stock chromium everything works fine for a long time without any patches with
--enable-features=VaapiVideoDecodeLinuxGL
I believe this flag only works on X11, not Wayland.
However, I am here to say that hardware acceleration doesn't work on Wayland (not XWayland). I am running on openSUSE Tumbleweed, Intel iGPU - UHD Graphics 620 (KBL GT2).
@kreaninw @oksakhartman @Cir-0 The patches related to HW decoding and acceleration are not outdated, and are either made by me, or from ungoogled chromium which keeps them up to date. I have forced VaapiVideoDecodeLinuxGL to true in source code, so setting that from the cmdline will not help anything.
I could make a beta build without any of the HW accel patches for ya'll to test. I could also look at what modifications that AUR package uses. I used to use the chromium-vaapi AUR package (made by the same maintainer, similar patches, just for X11) and it worked well.
Continuous, stable, easy (no manual fiddeling) hardware acceleration has been a shitshow on linux for a while now, on anything but a X11 + intel graphics system.
@oksakhartman Yeah then it must be my patches. Might have to remove some or all of them, or refactor them.
@oksakhartman @Cir-0 I'm pretty sure its this patch I use > https://github.com/ungoogled-software/ungoogled-chromium-archlinux/blob/master/ozone-add-va-api-support-to-wayland.patch It hasn't been updated since last year! I have simply been rebasing the files by adding/deleting lines as needed by comparing my current one with upstream's one.
It is probably breaking it. Instead I will use the patch from the wayland-vaapi AUR package.
Although I will add this to the repo soon, this will not come to users (you) until M114. I sometimes will rebuild to fix major crashes, but in general, I don't update, rebuild, and re-release a major Thorium version.
@kreaninw @oksakhartman @Cir-0 Please try the M114 version, and see if it fixes some or all of y'alls problems.

Thanks, I tried it, but it doesn't fix the issue. Here's some log that's occurred as soon as I played the video:

Note: I already blocked AV1 which is not HWA supported on my GPU.
Note 2: There's an upstream bug opening: https://bugs.chromium.org/p/chromium/issues/detail?id=1326754
@kreaninw @oksakhartman @Cir-0 Please try the M114 version, and see if it fixes some or all of y'alls problems.
v114 seems to have fixed the issue for me. I ran it right from the .zip's binary (I typically have it installed from the AUR but it hasn't been updated there yet), and with ozone hinting set to Wayland and hardware acceleration enabled, it launches right away in Wayland mode (not Xwayland), without the previous issues or terminal output.
Looking at "chrome://gpu", it has the same feature status as regular Chromium, except Thorium has "Video Encode" set to "Hardware accelerated", while regular Chomium has "Video Encode" set to "Software only. Hardware acceleration disabled".
Here's the "Video Acceleration Information" in Thorium from chrome://gpu:
Decode h264 baseline
16x16 to 4096x4096 pixels
Decode h264 main
16x16 to 4096x4096 pixels
Decode h264 high
16x16 to 4096x4096 pixels
Decode vp9 profile0
16x16 to 8192x4352 pixels
Encode h264 baseline
321x241 to 4096x2160 pixels, and/or 30.000 fps.
Encode h264 main
321x241 to 4096x2160 pixels, and/or 30.000 fps.
Encode h264 high
321x241 to 4096x2160 pixels, and/or 30.000 fps.
I'm not sure if other codecs, like AV1, are supposed to be here.
It might be worth noting that viewing a 4k video on Youtube uses ~15% CPU usage with Thorium, ~10% CPU usage in regular Chromium, and less than 1% CPU usage with Firefox Developer Edition (in Wayland mode with hardware acceleration enabled), which tells me that either hardware acceleration isn't working with youtube videos (VP9 codec) in Thorium/Chromium, or not as well as it should. Most video content I watch is through Youtube, so I will be sticking with Firefox for now until Thorium/Chromium can get CPU usage on par with Firefox. (I use Firefox instead of Mercury because Firefox is more stable for me, and Mercury is too out of date for me to comfortably use.)
Chiming in myself here, I noticed that decoding and encoding actually worked pretty well by ENABLING UseChromeOSDirectVideoDecoder up until 114. (i5-6300U, Intel(R) HD Graphics 520 (SKL GT2))
113 looked like this:
Then 114 started doing this???
The VDA decoder never worked for me personally, it has always shown hardware acceleration on with H.264 encoding and decoding in the Video Acceleration Information, but I always see logs like this:
[4389:4389:0729/130008.904971:ERROR:gl_display.cc(520)] : EGL Driver message (Critical) eglInitialize: Could not make the initialization pbuffer current.
[4389:4389:0729/130008.909743:ERROR:gl_display.cc(520)] : EGL Driver message (Critical) eglInitialize: Could not make the initialization pbuffer current.
Let me know if more information is needed from me, I'm on Debian 12 using the intel-media-va-driver-non-free. Using the free one causes nothing to show up in Video Acceleration Information, with video encode and decode still being hardware accelerated at the top of the page???
@kreaninw @ariankordi @oksakhartman @Cir-0 I have once again tried to fix this in the M115 release. Can ya'll please test and report back.
Not working for me, although I have a different GPU (Intel 4th gen Haswell HD 4400). Tried with a lot of different flags combination.
Same here, now the entire Video Acceleration Information section is blank for me 😕 with ChromeOSDirectVideoEncoder on or off, using intel-media-va-driver-non-free and free, on a fresh profile...

@oksakhartman It has never worked for me on unpatched Chromium, especially on Wayland.
Let me play with toys then.
@konradmb @oksakhartman @ariankordi @Cir-0 @kreaninw
Try passing only the following startup parameters
--enable-features=VaapiVideoDecoder,VaapiVideoDecodeLinuxGL
If there are corresponding function switches in chrome://flags, they can also be turned on.
If no other hardware acceleration patches are added, the hardware acceleration of the current Linux version should only support VAAPI, and it is best to ensure that the graphics card driver is working properly and is up to date.
Please note that passing the above two startup parameters on the Linux platform may not necessarily enable hardware acceleration, and a soft solution is required for final guarantee.
@konradmb @kreaninw @ariankordi This is actually expected. I removed the wayland vaapi patch, as it was causing too many bugs. Chromium doesn't have HW video decode acceleration on wayland at all upstream.
Im sorry.
If someone can find an up to date/working patch, then I can add it. The one I was using was from arch linux and was very outdated, not to mention that it changed files that are already changed by the vaapi and vdpau patches.
@gz83 The only patches now are straight from Ubuntu. A patch for older i965 drivers for VA-API, and VDPAU patch for Nvidia cards (only works when libvdpau-va-gl1 is installed).
These patches are: https://github.com/saiarcot895/chromium-ubuntu-build/blob/master/debian/patches/ihd-support.patch and https://github.com/saiarcot895/chromium-ubuntu-build/blob/master/debian/patches/vdpau-support.patch
--enable-features=VaapiVideoDecoder,VaapiVideoDecodeLinuxGL
yields:
"VaapiVideoDecoder: failed Initialize()ing the frame pool"
This is with Wayland/Polaris10. The good news is at least it's trying now:
@oksakhartman The i965 patch shouldn't interfere with VAAPI for other things, but that doesn't mean it doesn't.
The reason I use those two patches is because Ungoogled Chromium, Debian, and Ubuntu use them and has been well tested. Since Mesa 21, the i965 driver is used for 3rd Gen intel and below, which still makes up a significant portion of users.
I use vanilla chrome with only this --enable-features=VaapiVideoDecodeLinuxGL
But i affect this bug: https://bugs.chromium.org/p/chromium/issues/detail?id=1467689
thorium fix it ?
same here on Ubuntu 23.04 google-chrome-stable after a switch to Wayland (in flags, #ignore-gpu-blocklist
is set to Enabled, #ozone-platform-hint
set to Wayland).
would be real grateful if someone can give me at least a temporary fix because i tried a ton of flags and none worked. any more info i should provide?
@feakuru
If you're on NVIDIA, check my post here for flags (I managed to get full hardware acceleration in the past): https://www.reddit.com/r/wayland/comments/16gcci4/comment/k08acat/
I ended up switching to AMD and here's my updated/current flags: https://github.com/Alex313031/thorium/issues/207#issuecomment-1757130735
I saw this reported on Arch Linux forum.
Will it finally improve hardware acceleration on native Wayland from v119?

It seems that this patch is only merged in the main branch for the time being, and the corresponding version is 120
@Digitalone1
I use 119 beta Chrome and it contain the fix. I already tested.

What is your GPU and which flag do you use for the hardware acceleration?

Are you running Chrome/Chromium using ozone-platform=wayland
?
@Alex313031, is there any way to run Thorium with VAAPI under Wayland session with i965 driver for intel HD 4000 graphics?
And AMDGPU also. Thanks.
I tried Chromium 119 and still no hardware acceleration on AMDGPU. Tested both ozone Wayland and X11.
Looks like Chromium 120 fixed hardware acceleration on ozone Wayland for NVIDIA. VAAPI doesn't seem to work though.
https://bugs.chromium.org/p/chromium/issues/detail?id=1273758#c11
I cant even run Thorium on wayland. It rarely even opens, but even if it does, it crashes under a few minutes
@rabaimor i am on wayland (AMD gpu, nobara 39) and have zero issues running it. Post your specs, that'll help a lot.
@vampywiz17 @archerallstars @feakuru @Fiffian @Cir-0 I will be adding a flag to chrome://flags to control the VaapiVideoDecodeLinuxGL flag, since I have it enabled by default, but there are some instances you would want it disabled.
It might also help y'all to pass the --gtk-version=4
commandline flag
@vampywiz17 @archerallstars @feakuru @Fiffian @Cir-0 Added a chrome://flags/#vaapi-video-decode-linux-gl flag to M120.
I still have this issue with the latest Thorium 124 from AUR. Using Ryzen 5600g's GPU and amdgpu opensource driver. Using latest KDE Plasma.
If I don't switch to Ozone, then Thorium becomes sluggish and laggy from time to time, even to switch tabs.
But then with Ozone=Auto, all WebGL and hardware acceleration is disabled :( Testing with https://webglsamples.org/aquarium/aquarium.html and chrome://gpu
It seems the same issue reported at https://www.reddit.com/r/wayland/comments/17u282f/google_chrome_freezinglagging/

The upstream issue may be helpful to you, and comes with a patch. But please note that the patch I have landed in the M129 version, can you test the flags on your device and see if the patch works for you?
If the flags and patch work fine on your device, I will discuss with Alex whether to temporarily port the patch to Thorium.

System Details
Problem I am running Hyprland (v0.26.0-1.1), a tiling Wayland compositor. By default, Thorium launches using Xwayland. When manually setting the "Preferred Ozone platform" to "Wayland" in the flags, I noticed that it takes about 15 seconds to launch. When launched from a terminal, it outputs:
When disabling hardware acceleration in the settings, or launching with the parameters "--disable-gpu" or "--disable-gpu-compositing", it launches immediately, of course, with hardware acceleration disabled, but I would like it to be enabled and not running through Xwayland.
Additional Notes If launched with the parameter "--disable-gpu-process-crash-limit", it will output
GPU process exited unexpectedly: exit_code=7
indefinitely. I tried to look in the "Chromium code search" documentation, but could not find what exit code 7 means (I am not a programmer).I had this same issue with Thorium v112, on Hyprland v0.25 as well.
Regular Chromium (Version 114.0.5735.90 (Official Build) Arch Linux (64-bit)) does not have this issue and launches without error when "Preferred Ozone platform" is set to "Wayland", with hardware acceleration enabled.
