ah, it seems to be merged 17 hours ago into main tree :)

https://git.ffmpeg.org/gitweb/ffmpeg.git

see commits by Lynne

so 'just' building with ffmpeg.git (and probably fixing thirdparty/Makefile
so it does not disable vulkan for ffmpeg anymore - i hope building with old
vulkan headers was fixed? or we need to pass --disable-vulkan on "old" OSes
afterwards) should expose new encoder?
