gstcontrol
Dynamic parameter functionality
This library provides a Manager that maintains a list of dynamically
controlable parameters for a GstElement.
Just think of a volume slider in a mixer.
To use this library one needs to add some code to initialize it.
Adding the control library to a project
...
&hash;include <gst/gst.h>
&hash;include <gst/control/control.h>
...
gst_init(&argc,&argv);
gst_control_init(&argc,&argv);
...
The next step is to get hold of the GstDParamManager instance of a GstElement.
