GStreamer example

This is some example code that demonstrates how gstreamer can be integrated
with current Cocoa applications without occupying the entire window, so it is
embedded into a portion of the window only, leaving some room around the area
for other interactive ui elements. This way you can make media players or
control applications that require a tiny video view, but have rich interactive
requirements around that. I focused on minimalism to keep the example clear.

I'm submitting this to hopefully be integrated with the examples, so that
others working on Mac OSX have a better idea how to work with this.

=====================

README

This is an example of how to integrate gstreamer with osxvideosink without
straying
too far from XCode and the interface builder, where you can also define a
custom 
component that will be replaced by a video file. The rest of the user interface
can then
still contain your own components, buttons and elements.

The interface in the example has a custom view, which gets replaced by a
generated view 
component from gstreamer (added as a subview).

Resizing has not been implemented, but some boilerplate code is there that
allows
one to retrieve the new width and height after the resize operation. The Apple
docs
also have a demonstration on how to get the new size continuously during a
resize.

The example was built using the GStreamer supplied OSX packages available from
here:

http://docs.gstreamer.com/display/GstSDK/Installing+on+Mac+OS+X

Note how the linking and compilation configuration is done with a file
available in
the framework later on. See:

/Library/Frameworks/GStreamer.framework/Versions/Current/share/xcode

After that, the gst/gst.h file could still not be found, so I had to copy the
"User header paths" to the system paths in the same section to get the code to
compile.
