Thanks for the Info,

looking at the code, it seems support for running the streaming agent on
windows is not yet implemented, is there a blocker to this? (excluding the
build scripts, etc)

I think there is no blocker for running it on windows guests.
I never tried it.

Dear All

First of all, let me thank you again for your efforts!

I was reading on spice-streaming-agent, which is in experimental stage,
and
I was wondering what is the driver behind the idea?
Will that lead to less bandwidth consumption? less latency? or is it
just a
refactoring to make the codebase cleaner?

Hi,

It is possible to configure a VM with a hardware GPU (either assign the
whole
device to the VM or a part of it).
That is helpful for running, on the guest, applications that require such
strong GPU (e.g. 3D graphics).
When that is the case, spice-streaming-agent can use the GPU
on the guest
to stream video (encode the screenbuffer and send it).
This is what spice-streaming-agent does and it indeed leads to less
bandwidth used.

Uri.
