Description Evan Mohr 2025-04-04 21:52:13 UTC 
Description of problem:
I have an Intel N100, an Alder Lake chip (like Intel 12th gen), that has AV1 encode/decode support. However, it lacks AV1 encode/decode support despite being unencumbered by patents. However, Flathub

Version-Release number of selected component (if applicable):
intel-gmmlib-22.7.1-1.fc42.x86_64
intel-mediasdk-23.2.2-7.fc42.x86_64
intel-vpl-gpu-rt-24.4.4-2.fc42.x86_64
libva-intel-media-driver-25.1.4-1.fc42.x86_64
intel-audio-firmware-20250311-1.fc42.noarch
intel-gpu-firmware-20250311-1.fc42.noarch
intel-vsc-firmware-20250311-1.fc42.noarch

How reproducible:
Always on my Intel N100 system

Steps to Reproduce:
1. Run "sudo dnf install libva-utils"
2. Run "vainfo | grep -i AV1"
3. Ensure you have flatpak installed and Flathub enabled
3. Run "flatpak install flathub org.freedesktop.Platform.VaInfo//24.08"
4. Run "flatpak run org.freedesktop.Platform.VaInfo//24.08 | grep -i AV1"

Actual results:
On Fedora, I get no output regarding support for AV1 profile

On Flathub, I get an output regarding support for AV1 profile

Expected results:
Fedora should also have support for AV1 since the hardware supports it and it's an unencumbered patent.

Additional info:
I originally report this bug as a Fedora Flatpak issue before discovering it affected base Fedora too: https://gitlab.com/fedora/sigs/flatpak/fedora-flatpaks/-/issues/49

HI guys.

Situation has changed a bit, ("improved"?) - for as of now, with f43 it is that... AV1 decoder is missing but ! encoder is present:

-> $ vainfo 
Trying display: wayland
libva info: VA-API version 1.22.0
libva info: Trying to open /usr/lib64/dri-nonfree/iHD_drv_video.so
libva info: Trying to open /usr/lib64/dri-freeworld/iHD_drv_video.so
libva info: Trying to open /usr/lib64/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_22
libva info: va_openDriver() returns 0
vainfo: VA-API version: 1.22 (libva 2.22.0)
vainfo: Driver version: Intel iHD driver for Intel(R) Gen Graphics - 25.3.4 ()
vainfo: Supported profile and entrypoints
...
      VAProfileAV1Profile0            :    VAEntrypointEncSliceLP

above is with Intel's ARC A310.

Makes little sense - right? - for how many encode but... almost all, nope! all of us, decode.
thanks, L.
