No luck with vaapi

(1/1)

Vaguiner:
Hi. I recently switched to a mini pc (intel n100) and I'm having trouble enabling video acceleration.

vainfo (from libva22-utils):

--- Code: ---libva info: VA-API version 1.22.0
libva info: Trying to open /usr/local/lib/dri/iHD_drv_video.so
libva info: va_openDriver() returns -1
libva info: Trying to open /usr/local/lib/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_1_22
libva error: /usr/local/lib/dri/i965_drv_video.so init failed
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit
--- End code ---

I've tried them both: intel-media.tcz and intel-vaapi-driver.tcz. both at the same time and one on its own, always the same error.

A brief search on the internet indicates that:
i965 is not compatible with my integrated video, iHD is recommended.
Unfortunately tinycore's iHD was last updated in 2021. I'll try to manually compile an updated version to see the result.

Hi Vaguiner
Maybe this is pertinent:

another user mentions the n100 here regarding a potential heat dissipation deficiency with respect to an unintentional air gap between the cpu and heatsink:

For me it's the other way 'round, my GPU only works with the i965 VAAPI driver. However I need to load xf86-video-intel.tcz to get VAAPI to work, so try that if you haven't already got it installed.

I'm not sure if that would explain the error you get for iHD_drv_video.so though. For me iHD would load but init failed like you get with i965, but that was in an old TC version.

Also I ran the vainfo command as root, though I'm not sure if that was necessary.

Tips from my own VAAPI debugging:

Force using a particular VAAPI driver like this:

--- Code: ---# LIBVA_DRIVER_NAME=i965 vainfo -a
# LIBVA_DRIVER_NAME=iHD vainfo -a

--- End code ---

If the DISPLAY environment variable is set to a remote display (eg. "ssh -X"), vainfo shows drivers failing with "init failed". You need to unset DISPLAY like this:

--- Code: ---# DISPLAY= LIBVA_DRIVER_NAME=i965 vainfo
error: XDG_RUNTIME_DIR is invalid or not set in the environment.
error: can't connect to X server!

It took me ages to figure that out, but I guess it's mainly a "just me" problem. Probably not many others trying to use VAAPI while connecting remotely with X windows displaying over the network.

Hi. Thanks for the replies. The problem really was outdated intel-media. I managed to update both intel-media and intel-gmmlib and it worked again:
