Comment:

@ehfd I'm trying to check that this package even works.

On ubuntu 24.04 i install 

sudo apt install vainfo --yes
mamba create --name vainfo libva-utils --yes
mamba activate vainfo
23:43 $ vainfo

so ubuntu's versions works, but not ours.

hmaarrfk commented 2 weeks ago

Hmm it seems to need

ln -s /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so ${CONDA_PREFIX}/lib/dri/.

the it works...

hmaarrfk commented 2 weeks ago

seems like we might need https://github.com/intel/media-delivery

hmaarrfk commented 2 weeks ago

maybe it is https://github.com/intel/media-driver

ehfd commented 2 weeks ago

It's simply because there is no iHD_drv_video.so in the directory Conda's vainfo looks for. A patch similar to what @traversaro did in libglvnd is required.

ehfd commented 2 weeks ago

While adding the Intel media driver, sure, is a way to go, another more effective way is to expand the path of the VA drivers to the system ones.

hmaarrfk commented 2 weeks ago

hmm, ok, understood. thanks for the pointer!

btw, with the intel-media-driver (see staged recipe cross referenced)

I get even more codecs... I guess because it is newer???

hmaarrfk commented 2 weeks ago

Ok thanks for the pointer, we likely need to adjust libva

https://github.com/intel/libva/blob/master/meson.build#L78

in a similar way to: https://github.com/conda-forge/libglvnd-feedstock/blob/main/recipe/libglvnd_look_for_egl_icd_in_system_location.patch

hmaarrfk commented 2 weeks ago

On ubuntu the drivers are installed in:

/usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so

the fact that they are in this directory makes me feel like it is hard to point to, and we might as well build the "userland" driver ourselves no?

ehfd commented 2 weeks ago

I amend my previous answer. There should be enviroment variables for this situation such as LIBVA_DRIVERS_PATH and LIBVA_DRIVER_NAME. Then, it doesn't matter.
