Re: chromium: hardware video acceleration with VA-API

Is this broken again?

I cant seem to get it to work on 103 with nvidia or intel on X11 or wayland... with the same configs it worked with before

EDIT: This is actually working on nvidia, both x11 and wayland, with vainfo: Driver version: VA-API NVDEC driver
Chromium however, says gpu is not working and hardware decode is not working. So the browser is giving bad info. I can watch the gpu with pip program ./gpustat -p --watch 1 and watch the gpu usage and gpu memory assosciated with the browser raise and lower as I play and pause the video.

I cannot do the same with intel though using intel_gpu_top. The video section just sits flatlined at 0. I have gotten it to work with firefox on intel i965

Re: chromium: hardware video acceleration with VA-API

Is this maybe after an S3 cycle only?

Re: chromium: hardware video acceleration with VA-API

no its off of a fresh boot

The browser appears to show hardware decoding as not working regardless of what it's actually doing.

I can get the hardware decode to work with nvidia on x11 and wayland
I cant get it to work with intel i965. I know the gear and the drivers are good because I can get it working on firefox..... just not chromium based stuff. So the problem is browser specific

Re: chromium: hardware video acceleration with VA-API

I took some screenshots to show what im saying

https://imgur.com/a/5ucPzi9

Here are the chromium flags

--ignore-gpu-blocklist
--enable-gpu-rasterization
--enable-zero-copy
--enable-features=VaapiVideoDecoder
--disable-features=UseOzonePlatform
--use-gl=desktop

And here is what I am saying about it working with NVDEC despite the browser not knowing
https://imgur.com/a/bNJMSQD

Notice the gpu usage, and the memory in use on the card by process 3119 in between paused and play states on the video


I think the flags are right, the packages are right, its just something has broken somewhere

Re: chromium: hardware video acceleration with VA-API

Archwiki says AV1 hardware decoding  is not available on Chromium? But some posters here said it requires new hardware. I have 11.th gen Intel cpu which supports AV1 hardware decoding. Both vainfo and firefox confirms this. Bu I couldn't get it working on neither chromium nor chrome.

So my question is AV1 hardware decoding still not possible on Linux/Chromium or am I doing something wrong?

My config file:
--enable-features=VaapiVideoDecoder,VaapiVideoEncoder
--disable-features=UseChromeOSDirectVideoDecoder
--use-gl=desktop
--ignore-gpu-blocklist

chrome://gpu reports VideoDecode and VideoEncode hardware accelerated and Video Acceleration Information section only include h264, vp8 and vp9.

Re: chromium: hardware video acceleration with VA-API

I have a somewhat working setup with an UHD 620 (Carbon X1 7th gen i7), chromium 104.0.5112.79-1, intel-media-driver 22.4.4-1, running gnome w/ Wayland  and the following chromium-flags (no changes to chrome://flags):

--ignore-gpu-blocklist
--disable-gpu-driver-bug-workarounds
--enable-accelerated-video-decode
--enable-features=VaapiVideoDecoder,VaapiVideoEncoder
--use-gl=egl
--disable-features=UseChromeOSDirectVideoDecoder

Output of chrome://gpu (sorry for the bad formatting...):

<CPU> Vulkan backend - SwiftShader Device (Subzero)
[Default Toggle Names]
lazy_clear_resource_on_first_use: https://crbug.com/dawn/145: Clears resource to zero on first usage. This initializes the resource so that no dirty bits from recycled memory is present in the new resource.
use_temporary_buffer_in_texture_to_texture_copy: https://crbug.com/dawn/42: Split texture-to-texture copy into two copies: copy from source texture into a temporary buffer, and copy from the temporary buffer into the destination texture when copying between compressed textures that don't have block-aligned sizes. This workaround is enabled by default on all Vulkan drivers to solve an issue in the Vulkan SPEC about the texture-to-texture copies with compressed formats. See #1005 (https://github.com/KhronosGroup/Vulkan-Docs/issues/1005) for more details.
vulkan_use_d32s8: https://crbug.com/dawn/286: Vulkan mandates support of either D32_FLOAT_S8 or D24_UNORM_S8. When available the backend will use D32S8 (toggle to on) but setting the toggle to off will make it use the D24S8 format when possible.
vulkan_use_s8: https://crbug.com/dawn/666: Vulkan has a pure stencil8 format but it is not universally available. When this toggle is on, the backend will use S8 for the stencil8 format, otherwise it will fallback to D32S8 or D24S8.

If I watch a video with avc1.4D401F,mp4a.40.2 in chromium (e.g., on twitch), I can see intel_gpu_top showing activity for Video and VideoEnhance and CPU usage stays relatively low. So far so good.

However, it feels to me like chromium's performance degrades after i started the video: the video starts out fine but becomes laggier (less FPS) over time. Also chromium animations (e.g., opening a new tab) are less smooth while watching the video.

Anyone else having this experience?
