Hi, This a formal attempt of including virtio-media device specification. Virtio-media came from a discussion on virtio-dev mailing list, which lead to presenting virtio-v4l2[1] specification as an alternative to virtio-video. Later, virtio-v4l2 was renamed to virtio-media[2] and published through: https://github.com/chromeos/virtio-media The repository above includes a virtio-media driver able to pass v4l2-compliance when proxying the vivid/vicodec virtual devices or an actual UVC camera using the V4L2 vhost device (available in the repository). Steps to reproduce are also detailed[3]. There is some overlap with virtio-video in regards to which devices it can handle. However, as virtio-media will likely be the virtualization solution for ChromeOS (already landed into the chromeos organization) and possibly other Google projects for media devices, it would be desirable to include the specification in the next virtio release despite the aforementioned overlap. The device ID in this document differs from the ID in the virtio-media project repository. And it will probably need some discussion on which would be the correct definitive ID.
