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)
Just for reference, - on latest 4.3.9 ovirt node ng [root@ovirt ~]# ldd /usr/lib64/libspice-server.so.1.12.4 | grep -i gst [root@ovirt ~]#
- on latest 4.4 beta4 ovirt node ng [root@novirt2 ~]# ldd /usr/lib64/libspice-server.so.1.13.0 | grep -i gst libgstapp-1.0.so.0 => /lib64/libgstapp-1.0.so.0 (0x00007f8b7845f000) libgstvideo-1.0.so.0 => /lib64/libgstvideo-1.0.so.0 (0x00007f8b781c3000) libgstbase-1.0.so.0 => /lib64/libgstbase-1.0.so.0 (0x00007f8b77f4c000) libgstreamer-1.0.so.0 => /lib64/libgstreamer-1.0.so.0 (0x00007f8b77c0c000) [root@novirt2 ~]#
Cool,
Plus, you need the plugins for encoding in your host.
In term of? Packages? How to check?
Gianluca
In terms of packages, that can vary a bit due license/patent code but as quick check, spice's autotools does checks the following: https://gitlab.freedesktop.org/spice/spice/-/blob/master/configure.ac#L93 x264enc element is in gst-plugins-ugly while vp8enc and vp9enc in gst-plugins-good. You can check if you have each of those in the path by running gst-inspect-1.0, eg: $ gst-inspect-1.0 vp8enc | head Factory Details: Rank primary (256) Long-name On2 VP8 Encoder Klass Codec/Encoder/Video Description Encode VP8 video streams Author David Schleef <ds@entropywave.com>, Sebastian Dröge <sebastian.droege@collabora.co.uk> Plugin Details: Name vpx Description VP8 plugin Cheers, Victor
