Re: chromium: hardware video acceleration with VA-API

Wow we have actual chromium devs in this forum. Man I love this distro. The decision to switch to AVGLE on chromium 85 on Linux is kinda weird as WebGL and other graphics acceleration also doesn't work now on Linux by default. --use-gl=desktop is a must rn.

I'd be careful, AVGLE is... something else.

I'm not on the graphics team, but my understanding is that the switch to ANGLE is to make it easier to write GL code that works across the multiple OS targets that chromium supports, which at this point includes I think two-four linux distros, multiple windows, chromeos, android, fuchsia, and probably a few more I don't even know about. I'm also not aware of ANGLE breaking webgl acceleration, but that might just be me not being cc'd on a bug, since that's not my team anyway.

Using --use-gl=egl does not work for official extra/chromium because of the upstream bug. AUR chromium-vaapi patched it out for Wayland/EGL. Regardless of X.Org or Wayland session, --use-gl=egl simply doesn't work until the bug was fixed.

I don't think its safe to say that bug is going to be fixed any time soon, but I'll probably assign it to hiroh@ since it was his change in the first place. Using --use-gl=egl on linux is probably not going to get much official patch support unfortunately.

Re: chromium: hardware video acceleration with VA-API

Hi All,

Just to let you know, the latest version of chromium (85.0.4183.83) runs perfectly with hardware video acceleration under gnome wayland with the --use-gl=egl switch, on a nvidia optimus laptop (dell xps 15 7590) using the intel graphic card, battery consumption is much lower (12 mw) than firefox (24-30 mw) with webrender playing a 4k youtube video. It's perfect, thank you for the developers and packagers.

Re: chromium: hardware video acceleration with VA-API

I'm surprised to notice that the latest version of Chromium is using lower cpu resources while gpu decoding is enabled compared to Firefox.

How is this possible? I didn't use Chromium from July which was producing stuttering on 1080p60 h264 videos while other formats were playing smooth.

Now on Gnome Wayland with my old radeon card it's only working with use-gl=desktop, with both upstream and liewkj versions.

Maybe because that flag is disabling Angle? Anyway, use-gl=egl never worked to me since I began using Wayland in June.

So use-gl disables ANGLE and I confirm `desktop` is the only option enabling hardware acceleration on my system with Gnome Wayland.

Unfortunately, sometime I keep getting stuttering on 1080p60 h264 playback while it's not happening in Firefox, but generally Firefox uses more cpu while hardware decoding is enabled, even on lower formats.

Hardware decoding is good on Firefox on every site I tried, except on Twitch where it stops randomly. The website itself is having compatibility issues with Firefox while that's not happening with Chromium.

Re: chromium: hardware video acceleration with VA-API

I can't compile chromium-vaapi, gn from official repo

extra/gn is currently targeting Chromium 86. It's usually backward compatible but it does seem to have broken Chromium<86 builds.

As an immediate fix, you can change the gn dependency to gn-m85 (and the "gn gen ..." call to "gn-m85 gen ...") to build Chromium 85.

Please let me kindly ask you for a hint. How do I accomplish that for a package downloaded from the repo? I assume that all files are overwritten anyway when I run the package manager, aren't they?

Plus,I was only able to find 'gn' in the 'makedepends' section of PKGBUILD.

As expected, if I change the gn dependency and the gn call as advised, I get

makepkg --syncdeps
==> Making package: chromium-vaapi 85.0.4183.121-1 (Mon Sep 28 11:43:28 2020)
==> Checking runtime dependencies...
==> Checking buildtime dependencies...
==> Installing missing dependencies...
error: target not found: gn-m85
==> ERROR: 'pacman' failed to install missing dependencies.
==> Missing dependencies:
  -> gn-m85
==> ERROR: Could not resolve all dependencies.

as a consequence. So it looks like there is something missing.

There is, btw. a package named chromium-dev in AUR which appears to be based on Chromium 87.
Hence, it should avoid at least that gn related error.

But how will it be possible to include vaapi as well as vdpau support in this package?

Bingo, maybe it will work, I'll check later, thanks

for now, the only version that works with --use-gl=desktop is 87 dev

Re: chromium: hardware video acceleration with VA-API

Really BAD news for AMD!
The just-released mesa-20.2.0, libva-mesa-drivers radeonsi is busted. Chromium-vaapi crashed hard when anything touched VA-API in the browser and dmesg was flooded with amdgpu/iommu error and timeout. Went back to 20.1.8 and everything was nice and working.
However, gstreamer-vaapi works with libva-mesa-drivers 20.2.0 through gst-play-1.0, so it is hard to tell who to blame at this point, Chromium or MESA VA. Intel GPUs do not use MESA VA drivers, they maintain their own drivers and everything works fine with chromium-vaapi, gstreamer-vaapi and mesa-20.2.0. It is really just AMD users are impacted.

Nouveau also requires libva-mesa-drivers, I am going to check it out next to figure out if this is just radeonsi or affects all flavors of MESA VA drivers. This could be something that will take a long time to resolve, unfortunately....

What do you have GTK, QT or other?

it seems to me that GTK3 is incompatible with chromium

Re: chromium: hardware video acceleration with VA-API

AUR chromium-vaapi was not built with ANGLE. Chromium 85 ANGLE does not support VA-API at all on Linux. ANGLE support for VA-API will arrive by Chromium 86, we shall see.

ANGLE is just an OpenGL ES 2.0 middleware abstraction so that the upper level software always talk OpenGL ES 2.0 while ANGLE manages the lower level display/graphics implementation for ChromeOS, Windows and Linux, or any re-targetable platforms in future. ANGLE exposes several undocumented, unregistered extensions and sometimes the upper level software simply forgot about it and use them without considering non-ANGLE implementation as with `--use-gl=desktop` and `--use-gl=egl`. This is when things break.

It seems that ANGLE has been shaping up over the years and desktop GL and EGL are en-route for deprecation.

chromium 86 no longer needs patching, supports vaapi, let's see if it works stably

Re: chromium: hardware video acceleration with VA-API

I updated chromium to v86 and the drag and drop bug is fixed.
But now i get:

Video Decode: Software only. Hardware acceleration disabled

and

Accelerated video decode has been disabled, either via blocklist, about:flags or the command line.
Disabled Features: video_decode

I removed all command line arguments and reset flags but i still get the same error. Maybe because i'm using Nvidia?

Re: chromium: hardware video acceleration with VA-API

I removed --ignore-gpu-blacklist and --use-gl=desktop, and added --enable-accelerated-video-decode to get acceleration on v86.

Thanks! Adding that option worked.

Re: chromium: hardware video acceleration with VA-API

For NVIDIA, added both added --enable-accelerated-video-decode and --ignore-gpu-blocklist for my system to work. Using chromium 86 and libva-vdpau-driver-chromium; but only getting h264 (baseline, main, high) decoding. Is this normal, or should there also be v8 / v9 entries?

Re: chromium: hardware video acceleration with VA-API

for VP9 support build libva-vdpau-driver-vp9 with AUR

unfortunately at this level only VP9 profile 0 will be supported

Re: chromium: hardware video acceleration with VA-API

Hmmm, I still need --use-gl=desktop, otherwise I get this error:

 [96685:96685:1008/233232.904355:ERROR:gl_implementation.cc(286)] : Failed to load /usr/lib/chromium/libGLESv2.so: /usr/lib/chromium/libGLESv2.so: cannot open shared object file: No such file or directory

I'm using the NVIDIA drivers.

EDIT: just realized I'm using chromium-vaapi not chromium. which seems to be actually the broken one now! chromium works just fine, so just stick to extra/chromium.

Re: chromium: hardware video acceleration with VA-API

Some updates.....

Chromium 86 defaults to ANGLE, the Google's OpenGL ES 2.0 emulation layer. It seems that ANGLE default to desktop GL backend ie. GLX, but there is command line argument that allows that to be changed, `--use-angle=gles` or `--use-angle=gl-egl`. I am not sure what the difference between the 2 but they don't seem to work as well as GLX.

Since the ANGLE default backend is GLX, it failed to work on Wayland session (through XWayland) for VA drivers without DRI3, such as the Intel i965 and iHD. It is the same problem that Display handle obtained from vaGetDisplayGLX() cannot be used on Wayland session. MESA VA drivers support DRI3 so they work fine with ANGLE GLX backend. Unfortunately, MESA 20.2.0 screwed up radeonsi, so for VA-API to work for radeonsi on Wayland session one should defer MESA upgrade and stick to 20.1.8 (notably mesa and libva-mesa-driver).

Good news for NVIDIA, the upstream commit that enabled VA-API for ANGLE somehow removed VPP for no reason. It broke the native EGL code path which is essential for Wayland and so helped NVIDIA VDPAU wrapper which lacks implementation for VPP. Chromium VA-API now works on NVIDIA GPUs without the need to go for AUR.

I updated AUR chromium-vaapi to restore VA-API for Wayland/EGL while keeping NVIDIA support intact. VA-API on Wayland works for Intel and MESA VA drivers (nouveau, r600). Hopefully, radeonsi issues would be resolved in future.

It is likely that upstream Chromium will ignore Wayland support and continue tearing EGL code path apart en-route for deprecation. If this is the case, then it is very unfortunate and I hope not.

Re: chromium: hardware video acceleration with VA-API

However, gstreamer-vaapi works with libva-mesa-drivers 20.2.0 through gst-play-1.0

On which hardware? AMD?

Anyway, the latest mesa is not causing issues on Firefox vaapi decoding (wayland).
