[PATCH v2 0/1] virtio-media: Add device specification

[Albert Esteve <aesteve@redhat.com>]

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.
