Re: chromium: hardware video acceleration with VA-API

With these flags I think vaapi is working as chromium://media-internals suggests that VDADecoder is in use during this video: https://www.youtube.com/watch?v=LXb3EKWsInQ

--use-gl=desktop
--extension-mime-request-handling=always-prompt-for-install
--force-dark-mode
--enable-features=WebUIDarkMode,OverlayScrollbar,VaapiVideoDecoder
--disable-features=UseSkiaRenderer

I'm using ungoogled chromium if that helps, though, IIRC in order to know if vaapi was working the decoder should be Mojo, did the devs change it?

Version is 95.0.4638.69
Forgot to add, I'm using an i5 11400 with X11

Yes, Mojo changed to VDAVideoDecoder a couple major releases ago.

Sadly, I have no luck with Chrome 95.0.4638.69 or Chrome Beta 96.0.4664.27.  Last to work was 94.0.4606.81.  i7-10710U w/ X11.

Re: chromium: hardware video acceleration with VA-API

I also have no luck with the above settings (or any other configuration I've attempted to tweak) using official/branded Chrome Stable 95.0.4638.69. If I go to chrome://gpu I see the following (yet videos are still software decoded):

Graphics Feature Status
Canvas: Hardware accelerated
Canvas out-of-process rasterization: Enabled
Compositing: Hardware accelerated
Multiple Raster Threads: Enabled
Out-of-process Rasterization: Hardware accelerated

Re: chromium: hardware video acceleration with VA-API

Running ungoogled-chromium from flatpak version 95.0.4638.69 gives following log in media-internals:

This is somewhat better than previous tries when chromium didn't even try to initialize VDAVideoDecoder and straight goes for VpxVideoDecoder. Now we just have to make it initialize VDAVideoDecoder successfully somehow. How to find the reason behind the unsuccessful init of VDAVideoDecoder?

HW video decode has worked for at least a half-dozen releases with various required flags (as of 94.0.4606.81 using '--enable-features=VaapiVideoDecoder --use-gl=desktop --disable-features=UseOzonePlatform').  As noted by others earlier in this thread, Chrome (and Chromium) 95 ripped out the fallback to use the old non-Ozone X11 backend even though Ozone's va-api implementation is still broken.  Hence why hw video decode no longer works...

Re: chromium: hardware video acceleration with VA-API

Can anyone tell what exactly the errors

[33:33:1101/002554.096605:ERROR:gpu_init.cc(454)] Passthrough is not supported, GL is desktop, ANGLE is 
[33:33:1101/002554.119776:ERROR:sandbox_linux.cc(374)] InitializeSandbox() called with multiple threads in process gpu-process.

mean? because I'm getting same error on Chrome 94.0.4606.81. Therefore, on enabling flags mentioned in earlier posts should enable HW acceleration on it. It is also failing to initialize VDAVideoDecoder just like Chromium 95.

Edit: 94.x isn't flatpak if it matters.

have you checked if your GPU supports VP9 decoding? If it doesn't it will use software decoding, nothing you can do about that. https://wiki.archlinux.org/title/Hardwa … son_tables

Re: chromium: hardware video acceleration with VA-API

I have Ryzen R3 5300U with Renoir graphics. Firefox successfully decodes VP9 video, as evidenced in the output of

cat /sys/kernel/debug/dri/0/amdgpu_pm_info

I can see VCN enabling when I use either Firefox or mpv. But neither Chromium, Opera nor Chrome seems to do that.

Re: chromium: hardware video acceleration with VA-API

Hmmm, only explanation I can think of is that intel-media-driver works better with chromium than libva-mesa-driver, maybe try the flags I posted above on a clean profile.

Re: chromium: hardware video acceleration with VA-API

I installed Chrome 94 on second laptop running Wayland (i5 8250u integrated graphics), installed intel-media-va-driver-non-free, and in about://gpu I got info about "Video Acceleration Information" field as:

Decoding (VideoDecoder)
Decode h264 baseline        16x16 to 4096x4096 pixels

Decode vp9 profile0            16x16 to 4096x4096 pixels
Encoding

Although I can't get hardware acceleration to work on that system either.
On my laptop (AMD 5300u, AMD Renior X11) this field is empty on all chromium installs.

Re: chromium: hardware video acceleration with VA-API

Just an update from my side:

Looks like version 95.0.4621.4 works best here when it comes to VA-API support and accelerated video playback. I just verified this by compiling a 97.x version which fails on initialization of VDAVideoDecoder:

GpuProcessHost: The GPU process crashed!

This does not happen with 95.0.4621.4 that I had to recompile due to the latest harfbuzz update as well.
Only drawback there: Any videos from sites other than YouTube are played using FFMPEGVideoDecoder, regardless of their codec being H.264 as well.
When I try to play a video someone sent me on Whatsapp, Chromium does not even seem to try to initialize the VDAVideodecoder:

"Selected FFmpegVideoDecoder for video decoding, config: codec: h264, profile: h264 baseline, level: not available, alpha_mode: is_opaque, coded size: [640,352], visible rect: [0,0,640,352], natural size: [640,352], has extra data: true, encryption scheme: Unencrypted, rotation: 90°, flipped: 0, color space: {primaries:SMPTE170M, transfer:SMPTE170M, matrix:SMPTE170M, range:LIMITED}"

In contrast, for YouTube, VDAVideoVideoDecoder is chosen automatically:

"Selected VDAVideoDecoder for video decoding, config: codec: h264, profile: h264 main, level: not available, alpha_mode: is_opaque, coded size: [1280,720], visible rect: [0,0,1280,720], natural size: [1280,720], has extra data: false, encryption scheme: Unencrypted, rotation: 0°, flipped: 0, color space: {primaries:BT709, transfer:BT709, matrix:BT709, range:LIMITED}"

Re: chromium: hardware video acceleration with VA-API

It is interesting that there seems to be almost no interest in this topic.
There are no responses or contributions, even in the bug reports.

Looks like nobody needs to care about video acceleration anymore as computers sold these days are fast enough to make accelerated video playback unnecessary.

According to information from the net (including this thread here), there are problems with Ozone running under X11. In particular, video acceleration (VA-API support) does not seem to work with Ozone enabled.
But, as far as I know, starting with Chromium 96.x, Ozone will be the default platform, and cannot be disabled. Hence, '--disable-features=UseOzonePlatform' will have no effect anymore.
If Ozone is not working as expected, all you can do, is revert to Chromium 95.x versions.

Good news: I am just testing 98.0.4696.4 (installed via the Chromium-dev AUR package). Hardware acceleration for video decoding appears to be working (no crash, VDAVideoDecoder chosen on YouTube). However, Video Encoding is set to "Software only".

If Ozone is not working as expected, all you can do, is revert to Chromium 95.x versions.

Good news: I am just testing 98.0.4696.4 (installed via the Chromium-dev AUR package). Hardware acceleration for video decoding appears to be working (no crash, VDAVideoDecoder chosen on YouTube). However, Video Encoding is set to "Software only".

Which flags did you use?
