Hi, Here is the 3rd version of virtio-video patches. This patch set consists of two changes. The first patch adds the virtio-video protocol. This is an updated version of v2 patch [1]. The second patch adds a new feature to use exported objects from different virtio devices, which are proposed in [2], as video buffers.
