[webkit-dev] WinCairo video

I know there are several companies who don't even want to mess with the
licenses of GStreamer or FFmpeg.  GStreamer's license isn't a problem, but
I'm not sure how legally safe the plugins are.  They certainly don't have
an indemnification clause in their licenses.  The dlls are still large
compared to WebKit, and I've had trouble compiling them from source and
debugging them on Windows.  The distributed versions from
freedesktop.orgalso use a version of libsoup that is too old to use as
the network backend
for WebKit.  I'd also like to remove the requirement of installing
GStreamer to build and run the unmodified WinCairo port to make it easier
for people who don't know much about WebKit to build and run it.

I'm not saying that GStreamer is out of the question in the future, but I
think there are more reasons to switch than to stay right now.
