gstreamer-java via FMJ on windows

[Thom]

Followed instructions elsewhere on this forum for installing gstreamer
on windows.

When trying to play media via gstreamer-java installed in FMJ (open-
source JMF implementation), I get the following exception.

Any ideas on what I should try next?

To be honest, I've never tried using gstreamer-java via fmj under windows.

Is the gstreamer install working ok?
i.e. gst-launch playbin uri=file://c:/some/path/to/media/file.avi works ?

Is gstreamer-java working?
i.e.
does org.gstreamer.example.SwingVideoTest work ok?

From the looks of that backtrace, I think the playbin element factory
failed to create an instance of playbin for some reason - it can do
that if the 'name' parameter contains invalid characters.

Other than that,I'm stumped, without going in and debugging it myself.

Have you tried the ffmpeg fmj backend under windows? or the ds9 one?
