Sorry for the inconvenience.

Which is true. Now we depends on GStreamer to enable the video support.
Before I believe the video support was not enable. Could you check it?
If ENABLE_VIDEO was set to 1?

I think we should turn the video support as default now but for you if
your platform doesn't have gstreamer then your build-webkit should

It doesn't help as Qt Multimedia on linux build a GStreamer backend :D.

There is no such support in QMake unfortunately, unless you hack
something horrible like in Qt where we build some stupid main.cpp
files which have for example #include <gst/gst.h> and if it fails to
compile we bail out. I'm not sure we could add such a step in the
build-webkit script.
