From a chat with one of the authors of Ambulant, the current
implementation has got a 'dump' function. So technically
it would be
rather simple to 'sample' output from the library and
place it into a
pipeline.

Some additional subjects were; SVG support (based on
Inkscape) into the
Ambulant player and using Gstreamer as 'backend' like
FFMPEG is now. Then
again; Ambulant claims it is feature rich, but from my own
experience it
is far from bugfree and has some very basic design
difficulties.

(Design problem is for example rendering alpha channels on
the
backend instead of keeping them transparent, transitions
look funny then)


IMHO it would be a great idea to use gstreamer as the
backend for
Ambulant and thus getting the SMIL2 part into a parser
element.


The point I personally got stuck with Gstreamer was
prototyping my SMIL
application into a gst-lauch pipeline. Incompare to for
example
Real-Helix-memleak-player, gstreamer was so slow/cpu
intensive with
overlaying multiple video streams. Maybe a chat on
IRC/Jabber would be
good over this topic.

I guess my goal would be that we end up with something that
enabled SMIL to be playing
in Totem without any changes to Totem itself.

The videomixer element could probably do with some
optimization work 
according to Wim. Maybe something else to try to make a SoC
project
of
