Vulkan & Frame Grabbing

[khadasnimi]

I’m looking to buy khadas vim4 in order to use it as a frame grabber.
Planning to 1600x1200.
I want to do some image processing in either opencv or vulkan.

1. Does it support Vulkan and what version of it?
2. Does it supports opencv on GPU?
   Thanks,

No, only on CPU.

Thanks for the reply.
Do you know if I can implement a form of async time warp with vulkan on the mali gpu?
I think it will require preemptive rendering to do it.
Are there references or examples for that?

Sorry, we don’t know much about this and also don’t have examples.

Maybe you can get some documentations from ARM.
