[RFC v2 0/2] spice: Add an option to forward the dmabuf directly to the encoder (v2)
Posted by Vivek Kasireddy 2 weeks, 2 days ago
This patch series adds options to select a preferred codec and also
to forward a dmabuf directly to the encoder module that is part of
the Spice server. Currently, gstreamer:h264 is the only combination
tested but additional work is ongoing to test other combinations. 

Tested with: -device virtio-gpu-pci,max_outputs=1,blob=true,xres=1920,yres=1080
             -spice port=3001,gl=on,disable-ticketing=on,dmabuf-encode=on,
              preferred-codec=gstreamer:h264

and remote-viewer --spice-debug spice://x.x.x.x:3001 on the client side.

Associated Spice server patches (v1) can be found here:
https://lists.freedesktop.org/archives/spice-devel/2023-January/052927.html

v2:
- Used the already available gl_scanout and gl_draw_async APIs instead
  of adding new ones to Spice.
- Improved the commit message of the second patch
