Re: chromium: hardware video acceleration with VA-API

sorry maybe off-topic, but is it possible to enable vaapi in electron apps like signal-desktop?

It used to work with Freetube.
So as long as you match the right flags/hardware/electron-release( so its chromium associated release) combination, it could work just as Chromium.

Re: chromium: hardware video acceleration with VA-API

Not a single problem after 120 release (ungoogled-chromium) on Intel. Dumping flags here, some of them are redundant at this point:

--disable-gpu-driver-bug-workarounds
--enable-features=VaapiVideoDecodeLinuxGL,UseChromeOSDirectVideoDecoder,CanvasOopRasterization,WebUIDarkMode
--enable-gpu-rasterization
--ignore-gpu-blocklist
--ozone-platform=wayland

I guess it's for newer intel generations. My ivy bridge doesn't manage.

Re: chromium: hardware video acceleration with VA-API

On my HD 4000 (Ivy Bridge Mobile) (with some flags) in chrome://gpu everything seems alright. But when playing actual video in chrome://media-internals, I can see warnings about falling back and error:

VaapiVideoDecoder: failed initializing the frame pool

  Video acceleration itself works on my OS (I tested it with mpv). If somebody could get it working on ivy, please tell how.

Re: chromium: hardware video acceleration with VA-API

I enabled hardware accelerated video decoding on Chromium with the following configuration:

i7-1355U

Gnome, Wayland

Installed packages: intel-media-driver, vulkan-intel

~/.config/chromium-flags.conf:

--enable-features=Vulkan,DefaultANGLEVulkan,VulkanFromANGLE

I didn't explicitly enable video decoding, but it just works with Vulkan enabled. Seems like the most modern configuration to me. Didn't experience any issues so far from short usage.

I also use flag --ozone-platform=wayland but it is not necessary for video decoding.

EDIT: turned out this is not very stable for me. If I would turn display off for some time, browser becomes frozen and i takes around a minute for it to return back. It's not crashing itself, but according to the logs, GPU process or something like that is crashed and probably being restarted.

Re: chromium: hardware video acceleration with VA-API

After update to 131, I got this regression (errors show up in chrome://gpu):

[6049:6049:1113/220408.223558:ERROR:gl_display.cc(497)] : EGL Driver message (Error) eglCreateContext: Requested version is not supported
[6049:6049:1113/220648.819176:ERROR:gl_display.cc(497)] : EGL Driver message (Error) eglCreateContext: Requested version is not supported

and of course I got no video acceleration. Anyone having similar problems?

The same error log shows on my amdgpu setup, but vaapi is working normally. Besides, there is also the following error log

[4867:4867:1114/174017.770009:ERROR:wayland_surface_factory.cc(241)] : '--ozone-platform=wayland' is not compatible with Vulkan. Consider switching to '--ozone-platform=x11' or disabling Vulkan

while vulkan wayland seems also working fine..

Re: chromium: hardware video acceleration with VA-API

Sorry, false alarm: apparently I just have to change "VaapiVideoDecode" to "AcceleratedVideoDecode". The old flag is no longer recognized

Re: chromium: hardware video acceleration with VA-API

On a site note though, has anyone got Chrome running on Vulkan backend with NVIDIA drivers? 'cos I can't. Seems that only AMD GPUs work at the moment?

Sure?
How have you checked? I use " sudo intel_gpu_top" ( I use Intel Xe GPU).
Id doesn't work for me with neither "AcceleratedVideoDecode" nor "AcceleratedVideoDecoder" (trailing "r").
For me it simply doesn't work.
But it works with 130.
Have you also enabled any flag in chrome:flags?

Well, it used to be VaapiVideoDecodeLinuxGL,VaapiDecodeLinuxZeroCopyGL, now you just replace "Vaapi" with "Accelerated": AcceleratedVideoDecodeLinuxGL,AcceleratedVideoDecodeLinuxZeroCopyGL

For reference, u can check the flag commands here.

By the way, i find

VaapiIgnoreDriverChecks

is also necessary on my amdgpu setup to make hw decode working.

NOw it is ok. But "AcceleratedVideoDecodeLinuxZeroCopyGL" prevents you for using the "VideoEnhance" feature from the GPU.

Is there anything for accelerated video encode ?

Re: chromium: hardware video acceleration with VA-API

Full Vilkan support on native Wayland:
--ozone-platform=wayland --use-vulkan --enable-features=Vulkan,VulkanFromANGLE,DefaultANGLEVulkan

Optional hint for Vulkan:
--use-gl=angle --use-angle=vulkan
--enable-features=UseOzonePlatform

Optional Wayland hint:
--enable-features=WaylandWindowDecorations

VAAPI Decode (basic):
--enable-features=AcceleratedVideoDecodeLinuxGL

also zero copy variant:
--enable-features=AcceleratedVideoDecodeLinuxZeroCopyGL

VAAPI Decode (more options, not guarantee to work on new versions):
--enable-features=VaapiIgnoreDriverChecks,UseMultiPlaneFormatForHardwareVideo,PlatformHEVCDecoderSupport

VAAPI Encode:
--enable-features=AcceleratedVideoEncoder

also some other old options:
--enable-accelerated-mjpeg-decode --enable-global-vaapi-lock --use-gpu-scheduler-dfs --cast-streaming-hardware-h264

Other "performance" options
--enable-zero-copy --canvas-oop-rasterization --enable-gpu-rasterization
--enable-features=CanvasOopRasterization

Enabling Web GPU (only with unsafe option):
--enable-gpu --enable-unsafe-webgpu

Also a lot of workaround options like:
--disable-gpu-driver-bug-workarounds --ignore-gpu-blocklist
But they are for situations when "nothing helped"

!!! Do not try to enable Skia Graphite with Vulkan -- you will get neither Vulkan, nor Skia Graphite working !!!
!!! RawDraw with Vulkan "works" but you'll get content with all text disappeared !!!
