Initializing <application>GStreamer</application>
When writing a GStreamer application, you can
simply include gst/gst.h to get access to the library functions.
Before the GStreamer 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.
A typical program would start like this:
#include <gst/gst.h>
...
int
main (int argc, char *argv[])
{
...
gst_init (&argc, &argv);
...
}
It is also possible to call the gst_init method with two NULL arguments.
Use the GST_VERSION_MAJOR, GST_VERSION_MINOR and GST_VERSION_MICRO macros to
get the GStreamer version you are building against or
use gst_version() to get the version you are linked against.
The popt interface
You can also use a popt table to initialize your own parameters as shown in the next code fragment:
int
main(int argc, char *argv[])
{
gboolean silent = FALSE;
gchar *savefile = NULL;
struct poptOption options[] = {
{"silent", 's', POPT_ARG_NONE|POPT_ARGFLAG_STRIP, &silent, 0,
"do not output status information", NULL},
{"output", 'o', POPT_ARG_STRING|POPT_ARGFLAG_STRIP, &savefile, 0,
"save xml representation of pipeline to FILE and exit", "FILE"},
POPT_TABLEEND
};
gst_init_with_popt_table (&argc, &argv, options);
...
