It needs user to provide the options and for this feature to work streaming=filter or streaming=all must be giving to spice server to enable streaming. For mjpeg encoding, you don't need to change anything. For x264/vp8 with GStreamer, spice must be built with GStreamer option enabled. You can check if that's the case for your spice server library by running ldd in the .so file, e.g: spice (master 717ed19a) $ ldd ~/dev/lib64/libspice-server.so | grep -i gst libgstreamer-1.0.so.0 => /lib64/libgstreamer-1.0.so.0 (0x00007f393b57d000) libgstapp-1.0.so.0 => /lib64/libgstapp-1.0.so.0 (0x00007f393b568000) libgstbase-1.0.so.0 => /lib64/libgstbase-1.0.so.0 (0x00007f393b0df000) Plus, you need the plugins for encoding in your host. As mentioned earlier, the encoding parameters are hardcoded [0] so, even if you argue that gpu is preferred, that's not currently supported but patches are welcome!
