Request for pipeline/bin/element persistence #14

gstreamer has support for saving and loading elements, bins, and pipelines.
Would like to see this supported in gstreamer-java!

Argh, not sure how to change to 'enhancement'

Just had a look at the gst_xml api.  Its pretty awful.

Would an api something like:

java.io.File f = new java.io.File("/tmp/foo.xml");
GstXML xml = new GstXML(f);
Pipeline pipe = (Pipeline) xml.loadElement("pipe");

and

java.io.File f = new java.io.File("/tmp/foo.xml");
GstXML xml = new GstXML(f);
xml.saveElement(pipe);

Be sufficient for what you need?

Update to the latest source from mercurial and try out the GstXML class.

Its pretty much as described in the previous comment.

Let me know if its what you wanted.

I seem to be getting "GStreamer-CRITICAL **: pad sink is not a source pad" when 
I try
to load, but I am sure that's a gstreamer problem, not a gstreamer-java problem.

Barring that, this is exactly what the doctor ordered.

Thanks very much!

Can you post some sample code that reproduces that error?

I want to confirm if it is gstreamer itself or something I've done thats 
causing it.

No need, I have successfully saved and loaded a simple pipeline.

Unfortunately, I have been looking at the gstreamer mailing lists, and it would 
seem
that the gst xml is broken??? Well, at least, according to this post:
