From: Vivek Kasireddy <vivek.kasire...@intel.com>
Giving users an option to choose a particular codec will enable
them to make an appropriate decision based on their hardware and
use-case. Note that, the Spice server would use this codec with
Gstreamer encoder and only when gl=on is specified.
If no codec is provided, then the codec gstreamer:h264 would be used
as default. And, for the case where gl=off, the default codec to be
used is determined by the Spice server.
