Note that it's very likely to be due to changes in the browser.  The
media source API has been evolving, and the browser behaviors frequently
change with version updates.  I haven't been back to revisit this for a
while, and I know that it all needs a rework.

I articulated some technical details here:
  https://lists.freedesktop.org/archives/spice-devel/2015-June/020147.html

I've been waiting for the gstreamer code to go in so that I can come
back and attack this whole area.

Cheers,

Jeremy
