I use spice-streaming-agent with the goal that it can make the video
more fluent and use less bandwidth, because in my condition classic
SPICE can't do well with playing HD video and use high bandwidth. I
think SPICE have resolution to deal with these especially in a WAN
environment.
Developing streaming agent plugin is a good advice for me. I'll try it
and thank you !
Hi,
We have gstreamer based spice-streaming-agent plugin upstream, this
should let you use
any mjpeg/vp8/vp9/h264 gstreamer encoder plugin to encode your captured
desktop as a
video stream.
This plugin is not well tested and i do not know your exact
configuration but if your guest has
assigned gpu you may even find a suitable hw accelerated gstreamer
encoder plugin and this
potentially should work fairly well.

Is the display 2 showing the same content as display 1?
The second display is streaming your VM desktop using the MJPEG plugin.
This uses SW encoding in the guest and SW decoding on the client, so
it's adding significant CPU load and this use case has no actual
practical benefit (classic SPICE performs better).
I'm not sure what is your goal, but at this point, unless you want to
develop your own streaming agent plugin, you probably don't want to use
the streaming agent.
Cheers,
Lukas
