A patch brings hardware encoding with vulkan into ffmpeg. In the
future I will try to make a preset for h264, but if I understand
correctly you have to use the ffmpeg from Lynne's repository and then
compile it with the --enable-vulkan option. Do you think a simple
replacement of our ffmpeg tar.gz with Lynne's tar.gz is enough?

According to this current Phoronix news article
https://www.phoronix.com/news/FFmpeg-Adds-Vulkan-Video-Encode
"Since the release of FFmpeg 6.1 last year there has been
accelerated Vulkan Video decoding
<https://www.phoronix.com/news/FFmpeg-6.1-Released> support while
being merged to FFmpeg Git this weekend is the Vulkan Video encode
support.
The latest Vulkan Video patches by Lynne have now been upstreamed
into FFmpeg for enabling GPU accelerated video encoding using this
cross-vendor, cross-OS API. This Vulkan Video encode support is
currently in place for H.264 and H.265.
This Vulkan Video encode support is now in FFmpeg Git
<https://git.ffmpeg.org/gitweb/ffmpeg.git/shortlog> ahead of the
project's next release."

Possibly also AV1 Encoding support next was planned as listed in the
