To address the limitation that this option is incompatible with
remote clients, this patch series adds an option to select a
preferred codec and also enable gl=on option for clients that
are connected via the network. In other words, with this option
enabled (and the below linked Spice series merged), it would be
possible to have Qemu share a dmabuf fd with Spice, which would
then forward it to a hardware or software based encoder and
eventually send the data associated with the fd to a client that
could be located on a different machine.
Tested with: -device virtio-vga,max_outputs=1,xres=1920,yres=1080
-spice
port=3001,gl=on,disable-ticketing=on,preferred-codec=gstreamer:h264
and remote-viewer --spice-debug spice://x.x.x.x:3001 on the client side.
