Thread-topic: Camera Virtualization

[AMD Official Use Only - General]

Hello all,

We want to virtualize the camera that uses the V4L2 Linux drivers i.e.., wanted to use the Camera APP in DOMU.

Searched online and found 2 approaches to virtualize the camera.

FE and BE:

FrontEnd Driver is available at https://github.com/andr2000/linux/commits/camera_front_v1/drivers/media/xen

BackEnd Driver is available at https://github.com/andr2000/camera_be

VirtIO Implementation:

Collabora implemented the VirtIO Camera implementation and is available at https://gitlab.collabora.com/collabora/virtio-camera

Does anyone used above implementations?

Please guide us on which approach is best to use for Camera Virtualization?

Raghavendra M
