No, he means the libs
$ ffmpeg -i {INPUT}.mp4 vcodec libsvtav1 {OUTPUT}.mkv
But it does not use hardware acceleration of Nvidia.

Do you use Nvidia 4000 series?
There is no AV1 codec hardware acceleration when using older than Nvidia 3000 series.
Nvidia 3000 series supports AV1 decode only, not AV1 encode.

SvtMalloc[info]: you have no memory leak
I am using an nvidia 3000 series card, but even if that is the case, should ffmpeg not include the option and just fail when I try to run it?

@Zesko , @rabcor
is it possible that you have to uninstall the ffmpeg-package and install the ffmpeg-full-git from aur ? just a question from me. maybe @Zesko or others can answer.

rabcor:
you have no memory leak
That looks you have the limit of memory size. What size is your RAM? Did you enable Swap?
ffmpeg uses the lib libsvtav1 from the package svt-av1 that does not use Nvidia hardware acceleration, but your CPU and RAM.
Your Nvidia 3000 series does not have the ability AV1 encode.
See the wiki

32GB RAM, no swap, although i should probably enable that been lazy about getting around to it.

there’s no need to enable swap if you’re running 32 GB RAM with even some extraordinary use. if so use a swapfile, that’s a far better than a swap-partition.

Sorry, you can ignore this message. I can reproduce it, but it is not error after video conversion without any issue

Yeah it is not an error, no memory leak is a good thing.
