I have patches that could probably be useful to you for this: a 
simplification of the pipeline creation, optionally the use of 
decoebin, and for the performance aspects zero-copy for both the input 
buffer and the ouput frame. So I have created some github repositories 
to make it easier to get these:


https://github.com/fgouget/spice-gtk.git
 * gst branch
   All the above except for decodebin.

 * decodebin branch
   Uses decodebin instead of manually picking the decoders. However on 
   my machine decodebin tries to use vaapi which, given my test 
   configuration, immediately triggers an assert, thus killing the 
   process. Uninstalling vaapi fixes that but it's annoying. So I don't 
   really like the decodebin approach though it's probably more a vaapi 
   bug than a decodebin issue.


https://github.com/fgouget/spice.git
 * gst branch
   The patches adding GStreamer and VP8 support.

 * gst-1.0 branch
   Experimental branch with non-functional GStreamer 1.0 and h264 code. 
   Note that GStreamer 1.0 support can be disabled using './configure 
   --disable-gstreamer-1.0' so H264 support can be tested too.


https://github.com/fgouget/xf86-video-qxl.git
 * gst branch
   Has the patch to make it possible to specify the encoder:codec 
   pairs in either SpiceVideoCodecs or XSPICE_VIDEO_CODECS.


There are also spice-common and spice-protocol repositories but these 
should get pulled automatically.
