[Spice-devel] [v1] Add preferred video codec type message

[Victor Toso]

Hi,

The main idea here is to provide a way to chose codec type for video
stream. At this moment, the main purpose is making streaming in
different formats easy to test.

Ideally in the future, client could send upfront to the server what
client can hw decode. As discussed previously [0], gstreamer-vaapi
already only register what it can actually use in the system,
considering driver capabilites.

Previously, spice was taking into consideration what encoder and
video-codec to use based on the order it was defined. Patch 09
introduce (client-side) ranks. We might want to have server-side rank
to let the Admin disable some encoders if necessary... I guess.
