[Stratos-dev] virtio-camera interface

Hello,

I'm interested in the virtio-camera interface. https://collaborate.linaro.org/display/STR/Virtio+Interfaces

Would it include video-cam input (e.g. V4L2) or still camera only?

Also, are there any ideas to virtualize image processing units? It is possible to send the image to the other guest which processes the image and gets back, but it may involve many copies. If virtio-camera has such features, it will help to avoid copying so much. (something like USB-UVC)

BTW, is it possible to expose USB-gadget functions via virtio? (virtio-usb?)

Thank you,
