BTW, the latest driver that supports Slackware-15.0 (libva-2.13) is version 22.3.0

intel-media-driver-22.3.0
https://github.com/intel/media-drive...-22.3.0.tar.gz

intel-gmmlib-22.1.1
https://github.com/intel/gmmlib/arch...-22.1.1.tar.gz

Thank you. This is great news. I added this information to my fist post

I couldn't get the media driver to compile on my system. It got to 57% (media_libva_cp_interface.cpp.o) and crashed, complaining about an undeclared variable in the code.

Any chance you could add that to the docs?
https://docs.slackware.com/

If you for some reason can't. I could perhaps with your permission publish it for you there.

Aeterna · 02-19-2023, 05:11 PM

@hazel,
Your system is -stable or -current. I am running -current and compiling went fine. I just compiled again intel-media-22.6.6 my system is up to date so possible changes between the time of publishing howto and today did not affect compilation output.. hmm unless there is a change in slackbuild (assuming that you did use slackbuild)
@zeebra,
I never have written any of Slackware docs but I can certainly try. If I have problems I will let you know.

I use stable 15. I compiled the package by hand using the README as a guide; I didn't know there was a slackbuild for it.

ps: I just checked and the slackbuild is for an earlier version; I'll edit it for version 22 and see if that goes any better. If not, I'll try again with version 21.

I don't actually know if any of this would work for me as I have a Baytrail system-on-a-chip, which is fairly old hardware, but I don't have any hardware acceleration at all at the moment so I suppose it's worth trying.

Btw, I forgot to ask something. It's a bit embaressing, but I really have little clue about graphics. Do you have or is there any relevant similar information for virtual machines?

I assume the answer is no, and that it's an entirely different thing, but you seem to know about these things, so I ask you.

@hazel

Use sbopkg (slackware64-15)

intel-gmmlib 22.0.1
MD5 "cc15984a9e593d439d378b5ae5ebcda0"

intel-media-driver 22.1.1
MD5 "e29674d725868dbd398f46c684737039"

Checksums are from the official patches.

@zeebra
I don't think that hardware acceleration will work at all in VM, at least in the case of VirtualBox, VM is using very generic virtual video card, also OpenGL support is pretty old.

@hazel,
I updated howto on the first page (thanks to @babam). For Stackware-15 stable, you need to use a little older version of:
intel-media-drive 22.3.0
intel-gmmlib 22.1.1
because Slackware-15 stable uses libva-2.13

Slackbuilds has intel-media-drive-21-3-5 and intel-gmmlib-21-3-1. Will they do?

My understanding is that
intel-media-drive 22.3.0
intel-gmmlib 22.1.1

were tested with libva-2.13. I don't know about earlier versions.

I would edit slackbuilds accordingly.

Hi Aeterna, thanks for this, now Brave can have hardware-acceleration set (with "brave://settings/system") without the fans coming on all the time ;-).

Some observations (with KabyLake, 9th generation; i7-7700HQ; pipewire; re-compiled ffmpeg, slackware64-current) when trying this out.

1. No Guc or HuC output in dmesg.
2. Testing with vlc (or QMplay2 with FFmpeg-VA-API Decoder) instead of mpv worked fine; gave "Video" output in 'intel-gpu-top' of ~7-11%.

Code:

bash-5.2$ cvlc Big_Buck_Bunny_1080_10s_5MB.mp4 
VLC media player 3.0.17.3 Vetinari (revision 3.0.13-8-g41878ff4f2)
[0000000000b25c60] dummy interface: using the dummy interface module...
[00007ff630c138a0] avcodec decoder: Using OpenGL/VAAPI backend for VDPAU for hardware decoding

3. Brave leads to more "RENDER/3D" output (~20-25%, starting at ~39%) than Firefox (~8%, starting at 15%)(No "Video" output).

with "brave://gpu/" (colors from brave output):

4. FWIW (not being a versed ffmpeg user), the ffmpeg conversions falter at my end on:

Quote:

[Parsed_format_0 @ 0x18149c0] auto-inserting filter 'auto_scale_0' between the filter 'graph 0 input from stream 0:0' and the filter 'Parsed_format_0'

Error reinitializing filters!
Failed to inject frame into filter network: Function not implemented
Error while processing the decoded data for stream #0:0

Without the "-vf 'format=nv12,hwupload'" it worked (with "Big_Buck_Bunny_720_10s_2MB.mkv").

Nope, I can't get intel-media-22.3.0 to build, even using an edited slackbuild. It errors out at about 57% complete, just like when I did it by hand. Curiously, the error messages suggest actual errors in the code, undeclared variables and such-like.

It's not that important. I just wondered if I could get hardware acceleration on my video because I have none at the moment.
