The PDF is available in [1]. The first version was sent at [2]. Any feedback would be appreciated. Thank you.

We removed XBGR, NV21 and I422, as they are not used in the current draft implementation. https://lwn.net/Articles/806416/ - Removed virtio_video_control, whose usage was not documented yet and which is not necessary for the simplest decoding scenario. - Removed virtio_video_desc, as it is no longer needed. * Updated struct virtio_video_config for changes around capabilities. * Added a way to represent supported combinations of formats. - A field "mask" in virtio_video_format_desc plays this role. * Removed VIRTIO_VIDEO_T_STREAM_{START,STOP} because they don't play any meaningful roles. * Removed VIRTIO_VIDEO_T_STREAM_{ATTACH, DETACH}_BACKING and merged them into RESOURCE_{CREATE, DESTROY}. * Added a way to notify/specify resource creation method. - Added a feature flag. - Defined enum virtio_video_mem_type. - Added new fields in video_stream_create. * Modified fields in virtio_video_params. - Added crop information. * Removed enum virtio_video_channel_type because we can get this information by image format. * Renamed virtio_video_pin to virtio_video_buf_type. - It's similar to V4L2_BUF_TYPE_VIDEO_{OUTPUT, CAPTURE}. * Added an error event. * Reordered some subsections. * Changed styles to make it consistent with other devices.
