Getting Started
The dparams subsystem is contained within the
gstcontrol library. You need to include the header in
your element's source file:
#include <gst/control/control.h>
|
Even though the gstcontrol library may be linked into
the host application, you should make sure it is loaded in your
plugin_init function:
static gboolean
plugin_init (GModule *module, GstPlugin *plugin)
{
...
/* load dparam support library */
if (!gst_library_load ("gstcontrol"))
{
gst_info ("example: could not load support library: 'gstcontrol'\n");
return FALSE;
}
...
}
|
You need to store an instance of GstDParamManager in
your element's struct:
struct _GstExample {
GstElement element;
...
GstDParamManager *dpman;
...
};
|
The GstDParamManager can be initialised in your
element's init function:
static void
gst_example_init (GstExample *example)
{
...
example->dpman = gst_dpman_new ("example_dpman", GST_ELEMENT(example));
...
}
