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.
PDFs are avaliable below:
* full version [3]
* only virtio-video section (first patch) [4]
* only virtio-video section (first+second patch) [5]
Best regards,
Keiichi
