Once you register a session with some video (like playing something from youtube or better a normal video so you don't get all ADs) you can use spice-server-replay to play it. The useful options are - "-S" setting the streaming type, to force you can use 2 (all); - "-v" the video codecs used by the replay server, like "gstreamer:vp8"; - "-s" the streaming is affected by the timing, you have to try different values; - "--skip" combined with the "-s" you can skip part of it (like VM booting for instance); - "-c" your client command, usually remote-viewer with the specific options. I think there are client debugging options to check you are using streaming and the expected encoder (surely Victor knows these options more than me).
