As discussed by IRC in regards to the preferred video-codec message,
I've pushed it to my gitlab, you should be able to build with master
spice-protocol and the stream-preference branches from:
- https://gitlab.com/victortoso/spice-common
- https://gitlab.com/victortoso/spice-gtk
- https://gitlab.com/victortoso/spice

Let me know if you have any issues and comments/suggestions are welcome!

Cheers,
  toso
