--- Comment #5 from Francois Gouget <fgouget at codeweavers.com> ---
This patch works for me.

The colors are indeed a bit faded, which was already the case with the
GStreamer 0.10 ffenc_mjpeg version. That's particularly visible when Spice
switches from the native rendering to the GStreamer-based video streaming. But
otherwise I'm not sure one would really notice it. So while it would be nice to
improve this aspect, it's not a blocker.

Regarding jpegenc, the issue is that it does not have a 'bitrate' property and
as such is not a direct replacement for avenc_mjpeg. That's why I use
avenc_mjpeg in the Spice GStreamer backend: it can easily be substituted with
other encoders like VP8 or x264 with uniform code for adjusting each to the
network conditions.
