Already touched this topic barely in another thread
https://lists.cinelerra-gg.org/pipermail/cin/2023-December/007346.html
But so many SW and HW pieces are mentioned around, it is
almost a full-time reading and study:
VAAPI, MESA, VULKAN, Intel Quick Sync Video etc......
I realize my aging hardware which is fast enough for other
tasks, needs some "AV1 upgrade", if possible.
But first I wonder, what is expected possible to do (obtain)
with AV1 de-/encoding on my existing 64bit hardware:
1) laptop 2018: Dell XPS 13-9370: quad core i7-8550U CPU
(8. gen Kabylake) and Intel UHD Graphics
2) WS infinity: MSI Z170A mobo: quad core i7-6700K CPU
(6. gen Skylake), NVIDIA GeForce GT-730 graphics
I continue the "AV1 de-/encoding on my existing 64bit
hardware" question above as a branch here (instead of a new
related thread).
This part is also related to another 2021 thread, [Cin] tried
to update av1.webm profile
https://www.mail-archive.com/[email protected]/msg02804.html
which refere to FFmpeg's AV1 Video Encoding Guide
https://trac.ffmpeg.org/wiki/Encode/AV1
I took my first AV1 rendering test with CinGGs default av1.webm preset
by loading a standard SD DV file clip.

SVT-AV1 re-encoding
---------------------------------
I will add the re-encoded sample SD DV file using ffmpeg SVT-AV1, as I
was positive surprised how much faster (preset 10 about 25 sec) it was
than rendering AV1 with CinGG (libaom?) . I've tested three presets: 8,
10 and 12. "Useable visible quality" for all.

To start with the workstation 2) above, I want suggestions
how to test the possible AV1 encoding options (libaom,
SVT-AV1, MESA, VAAPI, VDPAU) using my system enabled ffmpeg
6.0.1 commands,, and also suggestions to required change in
system/graphics settings.
System output as background info:
fmpeg -encoders -hide_banner | grep av1
V....D libaom-av1 libaom AV1 (codec av1)
V....D librav1e librav1e AV1 (codec av1)
From phoronix articles librav1e and SVT-AV1 should be faster, but
sometimes at quality cost.
Sorry, not tried them personally due to svt demanding 64-bit
system and rav1e demanding rust.
So for this task you are on your own .. sorry!
https://ottverse.com/analysis-of-svt-av1-presets-and-crf-values/
may be crf 26 (ish) and preset 6 ?
On 36 core machine with avx512 it surely was fast, but on 4c .. I
guess 1.25 fps or so will be best you can get? (for fullhd source)
