On my system libva is at version 2.20.0; I don't know how to see the<br>
version of libva used internally by CinGG (if any).<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">We link to system's libva, so it should depend on version installed on build machine.

I guess, as Andrew says, internal libva is out of date, or use the<br>
system one directly.<br>
Important missing, besides the Intel ones, is av1_nvenc. I don't know<br>
if it depends on my system which is AMD and therefore doesn't have<br>
Cuda, or you have to manually enable the library. I see that Phyllis'<br>
system has only two libraries for av1 and all the others are missing.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">I think for this one we need to update our ffnvcodec.tar.xz</div><div dir="auto"><br></div><div dir="auto"><a href="https://github.com/FFmpeg/nv-codec-headers/commit/7947f29859f2fa7a9252309daeb4717030d027e0">https://github.com/FFmpeg/nv-codec-headers/commit/7947f29859f2fa7a9252309daeb4717030d027e0</a><br></div><div dir="auto"><br></div><div dir="auto">I guess SDK 12.x is earliest with av1 ENCODE.</div><div dir="auto"><br></div><div dir="auto">unfortunately, this might mean I lose nvenc acceleration on legacy nvidia proprietary 470 driver?

I additionally have only av1_vaapi. @Terje, you also use a rolling,<br>
can you see the encoders of CinGG's internal ffmpeg and the system<br>
libva version?<br>
<br>
I am attaching a new version of the preset for av1_vaapi, but there<br>
are many conditions for it to work: you have to install CinGG<br>
(appimage is no good, unless you know how to open and recreate it);<br>
new generation GPU (Nvidia 4000; AMD Radeon 7000; Intel Xe 2 or Intel<br>
Arc); system with updated libva (possibly Rolling...). If anyone meets<br>
the requirements, I would like to know if the preset works or what<br>
errors it gives. I used average options between quality and speed but<br>
could not test them because I lack the right hardware.<br>
