Yes, there is a RFE upstream to record a spice session and the last suggestion from Marc-André was to do that: https://bugs.freedesktop.org/show_bug.cgi?id=51714 > 2) developing some client software which can handle and switch between > multiple spice session upon choice or by some external event. So, you plan to keep the session live with several VMs in order to switch between them and also keep recording them. It could be considerable amount of data.

I always thought there should be a simpler way to record the display with some gtk3 api/feature but I never look into it.. and to be honest, a gstreamer plugin might give you a lot more flexibility. toso
