appsink is your friend and you can retrieve the VkImage's from
upstream and you can do what you like with them.<br>
<br>
There's no requirement to use vulkansink however you would need to
make sure to interop with the relevant Vulkan objects between the
application and GStreamer which may require some API additions in
GStreamer for that case. The design is similar to OpenGL
integration but there are some differences with how Vulkan itself
works that need to be accounted for when writing your own glue code.<br>

from running with vulkan elements with gst-launch-1.0, yes.
That's<br>
the only application example for Vulkan. Note that Vulkan
does work on<br>
macOS/iOS through the MoltenVK layer.<br>
