Introduction
============
The SPICE Streaming Agent is a guest-side daemon which captures the
guest video output, encodes it to a video stream,and forwards the resulting
stream to the host to be sent through SPICE. The capture and encoding are done
through the use of plugins, so a variety of video format and capture/encoding
methods (hardware/software) can be used. For now, spice-streaming-agent only
provides software encoding to MJPEG.
Virtual Machine Configuration
=============================
In order to set up streaming, qemu needs to expose a
`com.redhat.stream.0` virtio port, associated with a
corresponding Spice port.
Using virt-manager
------------------
In the hardware details, click on "Add Hardware", then select
"Channel". Add a "Spice port" device type with the
"com.redhat.stream.0" name. You also need to set "Channel" to
"com.redhat.stream.0"
Using libvirt
-------------
[source,xml]
<devices>
<channel type='spiceport'>
<source channel='com.redhat.stream.0'/>
<target type='virtio' name='com.redhat.stream.0'/>
</channel>
</devices>
Using QEMU
----------
[source,sh]
-device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel1,id=channel1,name=com.redhat.stream.0 -chardev spiceport,name=com.redhat.stream.0,id=charchannel1
