gstcontrol

gstcontrol — dynamic parameter functionality.

Synopsis


#include <libs/control/control.h>


void        gst_control_init                (int *argc,
                                             char **argv[]);


Description

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.

Example 1. Adding the control library to a project

...
#include <gst/gst.h>
#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.
