Hi, I'm running KDE plasma (5) under wayland. There should be support for VA-API under wayland in chrome/chromium for a while now. This would allow me to playback HEVC as due to patent issues it's not done in software, but if the hardware supports it that should be used. Whilst chrome://gpu shows that hardware decoding is enabled, the table that should list the codecs is empty. Can't playback HEVC either, just get audio with a black screen. I'm using a XPS 15 9510 laptop which has an Intel GPU (in the CPU) with a nVidia card. It's fine if it just uses the Intel one. With or without nvidia-drivers installed doesn't make a difference though. Have posted in the forums, but no responses whatsoever and at a loss with regards to where to look next. https://forums.gentoo.org/viewtopic-t-1167821-highlight-.html Reproducible: Always

If so that's not too surprising - VA-API is intel's open standard for this sort of thing. I'm not actually sure if we expect this to work on nvidia (proprietary drivers), at least not out of the box - nvidia uses NVENC/NVDEC instead and I don't believe that they have VA-API support.
Hi, yes va-api seems to work. The nVidia card is just supposed to offload heavy 3D to if I'm not mistaken. Not sure how to troubleshoot this though. Chrome should just use the Intel card. Have tried installing media-libs/nvidia-vaapi-driver, but that doesn't make a difference. chromium didn't list any codecs either and seems firefox doesn't use hardware playback either. No clue where it's breaking, vainfo seems fine. There was a point, quite some time ago, it listed codecs just fine. HEVC playback was broken though (lots of green stuff and artifacts), AVC was fine. This is over a year ago though. It has been like this for quite some time now, but should be officially working now. Might try if it works under Ubuntu live 24.04 or something.
nvidia-vaapi-driver only works with specific configurations[1] and is a bit of hack that acts as wrapper to nvdec (it's also not supported by nvidia itself) - consider yourself lucky if can get that to work at all in general vaapi is not supported with nvidia, need to use vdpau or nvdec instead but this is typically not supported by web browsers (some media players can use them, e.g. mpv -hwdec=nvdec). [1] https://github.com/elFarto/nvidia-vaapi-driver/blob/master/README.md tl;dr it says that chrome is not supported, this is primarily for use with firefox
It doesn't work without nVidia drivers either. It supposed to just use the intel drivers. That's also what's in the vainfo output.
I don't have any vaapi-supporting hardware to play with, so I can't reproduce this issue. I do see this in my Chromium output: ``` [2512238:2512238:0812/133057.627703:WARNING:vaapi_wrapper.cc(1523)] : Skipping nVidia device named: nvidia-drm ``` Which supports vaapi explicitly not working with nvidia. If I look at chrome://media-internals/ while browsing a few streams I see ffmpeg in use on nvidia which I suppose is normal. Here's my output for a definite h264 test video[1]: ``` 00:00:03.358 info "FFmpegDemuxer: created video stream, config codec: h264, profile: h264 high 4:2:2, level: not available, alpha_mode: is_opaque, coded size: [1920,1080], visible rect: [0,0,1920,1080], natural size: [1920,1080], has extra data: true, encryption scheme: Unencrypted, rotation: 0°, flipped: 0, color space: {primaries:BT709, transfer:BT709, matrix:BT709, range:LIMITED}" 00:00:03.358 duration 10 00:00:03.358 kAudioTracks [] 00:00:03.358 kVideoTracks [{"alpha mode":"is_opaque","codec":"h264","coded size":"1920x1080","color space":{"matrix":"BT709","primaries":"BT709","range":"LIMITED","transfer":"BT709"},"encryption scheme":"Unencrypted","has extra data":true,"hdr metadata":"unset","natural size":"1920x1080","orientation":"0°","profile":"h264 high 4:2:2","visible rect":"0,0 1920x1080"}] 00:00:03.358 kMaxDuration 10 00:00:03.358 kStartTime 0.033008 00:00:03.358 kBitrate 15156684 00:00:03.358 info "Cannot select DecryptingVideoDecoder for video decoding" 00:00:03.358 info "Cannot select VaapiVideoDecoder for video decoding" 00:00:03.358 info "Cannot select VpxVideoDecoder for video decoding" 00:00:03.358 info "Cannot select Dav1dVideoDecoder for video decoding" 00:00:03.360 kIsVideoDecryptingDemuxerStream false 00:00:03.360 kVideoDecoderName "FFmpegVideoDecoder" ``` What do you currently see Ferry? 1: https://telecommunication-telemedia-assessment.github.io/AVT-VQDB-UHD-1/test_1.html
Hi, what parameters are you using to get that output? You might be able to use media-libs/nvidia-vaapi-driver to get va-api support. Doesn't seem to output much by default. ~ $ google-chrome-unstable Created TensorFlow Lite XNNPACK delegate for CPU.

Chromium VA-API on X11 requires --enable-features=VaapiVideoDecodeLinuxGL on my systems instead of --enable-features=VaapiVideoDecode as recommended in elog. Without --enable-features=VaapiVideoDecodeLinuxGL, chrome://gpu shows the same "Video Decode: Hardware accelerated" with no accelerated codecs. Wayland, Vulkan, and other systems may require different flags, see https://wiki.archlinux.org/title/Chromium#Hardware_video_acceleration
