The Clutter-Gst library should be initialized
with clutter_gst_init() before it can be used. You should pass pointers to
the main argc and argv variables so that GStreamer, Clutter and Clutter-Gst
gst can process their own command line options, as shown in the following
example:
Example 1. Initializing the Clutter-Gst library
1 2 3 4 5 6 7 |
int main (int argc, char *argv[]) { // initialize the Clutter-Gst library clutter_gst_init (&argc, &argv); ... } |
It's allowed to pass two NULL pointers to clutter_gst_init() in case you
don't want to pass the command line arguments to GStreamer, Clutter and
Clutter-Gst.
You can also use a GOptionEntry array to initialize your own parameters as shown in the next code fragment:
Example 2. Initializing the Clutter-Gst library with additional options
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 |
static GOptionEntry options[] = { { "framerate", 'f', 0, G_OPTION_ARG_INT, &opt_framerate, "Number of frames per second", NULL }, { "fourcc", 'o', 0, G_OPTION_ARG_STRING, &opt_fourcc, "Fourcc of the wanted YUV format", NULL }, { NULL } }; int main (int argc, char *argv[]) { GError *error = NULL; gboolean result; if (!g_thread_supported ()) g_thread_init (NULL); result = clutter_gst_init_with_args (&argc, &argv, " - Test YUV frames uploading", options, NULL, &error); if (error) { g_print ("%s\n", error->message); g_error_free (error); return EXIT_FAILURE; } ... } |
ClutterInitError clutter_gst_init (int *argc,char ***argv);
Utility function to initialize both Clutter and GStreamer.
This function should be called before calling any other GLib functions. If
this is not an option, your program must initialise the GLib thread system
using g_thread_init() before any other GLib functions are called.
ClutterInitError clutter_gst_init_with_args (int *argc,char ***argv,const char *parameter_string,GOptionEntry *entries,const char *translation_domain,GError **error);
This function does the same work as clutter_gst_init(). Additionally, it
allows you to add your own command line options, and it automatically
generates nicely formatted --help output. Clutter's and GStreamer's
GOptionGroups are added to the set of available options.
Your program must initialise the GLib thread system using g_thread_init()
before any other GLib functions are called.
