summary
Explains how to virtualize stateless video decoders using the Virtio Video framework and VA-API, focusing on integrating Virtio Video with VA-API to enable hardware-accelerated decoding in guest VMs. Describes the technologies (Virtio Video, VA-API) and the approach for exposing host GPU/video decode capabilities to virtual machines without maintaining decoder state in the guest.
