How about version 21.3.5, did it build successfully?

Dunno, I haven't tried it. I'll try and see.

Hi Hazel, when compiling that intel-media package I noticed it took quite a while and the end product is big:

-rw-r--r-- 1 root root 10973939 Feb 22 22:22 intel-media-driver-22.6.6-x86_64-1ponce.tgz

Could it be that your 'tmp' space used for building gets filled up? Sometimes, when building something big and I don't clear my build-space the compiling falters without a clear reason.

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:

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

hth

1) this is what I see running cvlc (differences are hardware related, so all is fine):

Code:

cvlc Big_Buck_Bunny_1080_10s_1MB.mp4 
VLC media player 3.0.17.4 Vetinari (revision 3.0.13-8-g41878ff4f2)
[0000000031b40dd0] dummy interface: using the dummy interface module...
TagLib: MP4: No audio tracks
[00006f6ab4c11100] avcodec decoder: Using Intel iHD driver for Intel(R) Gen Graphics - 22.6.6 () for hardware decoding

2) ffmgeg conversion (I am not versed in ffmpeg either) should confirm the use of VAAPI so as long as you see:

Code:

...
[AVHWDeviceContext @ 0x1d19d40] libva: VA-API version 1.17.0
...
Stream mapping:
  Stream #0:0 -> #0:0 (theora (native) -> hevc (hevc_vaapi))
  Stream #0:1 -> #0:1 (vorbis (native) -> mp3 (libmp3lame)) <- or whetever encoder
[hevc_vaapi @ 0x1e10dc0] Using input frames context (format vaapi) with hevc_vaapi encoder.
...

should be fine
3) never used brave
but I assume that

Code:

brave://flags

should work: search for specific options and enable what you want. Of course some options are specific for chrome only.
I would enable

Quote:

Raw Draw

you have it disabled (not possible to enable?)

A note regarding WebGPU:

Quote:

Enables access to the experimental WebGPU API. Warning: As GPU sandboxing isn't implemented yet for the WebGPU API, it is possible to read GPU data for other processes. – Mac, Windows, Linux, ChromeOS, Fuchsia, Lacros

..so I did not enable WebGPU in chrome

4) GuC and HuC
Based on Intel info
/etc/modprobe.d/i915.conf
options i915 enable_guc=3
options i915 enable_fbc=1
should be set 0 (zero)
this means that GuC and HuC are not available for Kabylake

hope this helps

well just checked github site:

Quote:

Intel Media Driver 2021Q4 Release - 22.1.1

Official quarterly release including some enhancements and key fixes.
Dependencies

GmmLib: intel-gmmlib-22.0.1
Libva: 2.13.0

Supported Platforms

BDW (Broadwell)
SKL (Skylake)
BXTx (BXT: Broxton, APL: Apollo Lake, GLK: Gemini Lake)
KBLx (KBL: Kaby Lake, CFL: Coffe Lake, WHL: Whiskey Lake, CML: Comet Lake, AML: Amber Lake)
ICL (Ice Lake)
JSL (Jasper Lake) / EHL (Elkhart Lake)
TGLx (TGL: Tiger Lake, RKL: Rocket Lake, ADL-S/P/N: Alder Lake)
DG1/SG1
Alchemist(DG2)/ATS-M(Arctic Sound Mainstream)

this is your limit for libva-2.13 in -stable you can use intel media driver 22.1.1

anything above 22.1.1 probably will fail

It's tmpfs so it should expand as required, shouldn't it? du shows 1.8G currently. Anyway, I've got -22.1 building now. It takes a very long time to get anywhere, and if it fails, it will be around the 57% mark.

update: 59% and still building!

update: crashed at 68%!

The problem is in your system.

22.3.0 buildable on Slackware-15.0 (libva-2.13.0)

hazel · 02-25-2023, 01:36 AM

Must be something in my hardware then because I've got the right libva; I just checked.

Really I was just curious. I don't play games or watch videos so I don't actually need true hardware acceleration.

Yes, but it can be restricted; at my end it's set to 6G in the /etc/fstab

Code:

tmpfs                   /tmp                             tmpfs       size=6G,mode=777 
                           0   0

Maybe I should increase it ;-)

Ha, never used "brave://flags"; Thanks. BTW, it was default; setting this to `enabled` does not, at least, change the 'Render/3D' levels

Yes thanks; I had set "enable_guc=0" but left "enable_fbc=1", which seems to work with the 7th generation chip (I called it wrongly to be 9th generation; wishful thinking, haha ;-).

Arch has a nice guide for intel-graphics: https://wiki.archlinux.org/title/Intel_graphics

This thread is very helpful; thanks again.

No, mine uses only the default options.

Just as an experiment I tried rebuilding the package with the -j1 make option. LFS recommends this as a thing to try when a multi-core build crashes. But it still crashed in the same place.

@Aeterna I just was wondering if it works with a Kaby Lake / HD Graphics 620 as well?

Sorry, I meant

only.
Interesting link thank you. Unfortunately I am unable to edit my first post anymore otherwise I would include it for more reading for Slackware intel video users.

@lancsuk
Regarding Kaby Lake settings listed work. For some differences consult @brobr posts. I think that only GuC/HuC will not work so set enable_guc=0

Regarding HD Graphics 620, I am not sure to what extend will work. Maybe try and report back
which tests succeeded. Start with Kaby Lake as "positive control"

Great. You can enable Raw Draw and (Chrome) video encoding hardware accelerated
