When writing a <application>GStreamer</application> application, you can
|
||
|
|

Before the <application>GStreamer</application> libraries can be used
|
||
|
|
gst_init () has to be performed from the main app. this call will perform
|
||
|
|
first initialisation and will parse the GStreamer specific command line
|
||
|
|
options.

<programlisting>
|

|
|
#include <gst/gst.h>
|
||
|
|
|
||
|
|
...
|
||
|
|
|
||
|
|
int
|
||
|
|
main (int argc, char *argv[])
|
||
|
|
{
|
||
|
|
...
|
||
|
|
gst_init (&argc, &argv);
|

|
...
|
||
|
|
}
|
