[gst-devel] Enumering capture devices?

[Julien Isorce]

Hi,


Something like that:

#include <gst/interfaces/propertyprobe.h>

GstElement* videodevicesrc = create_element("dshowvideosrc", NULL);
GstPropertyProbe* probe = GST_PROPERTY_PROBE (videodevicesrc);
GValueArray* va = gst_property_probe_get_values_name (probe, "device-name");
for(guint i=0; i < va->n_values; ++i) {
    GValue* v = g_value_array_get_nth(va, i);
    g_print ("one more device: %s\n", g_value_get_string(v));
}
gst_element_set_state (videodevicesrc, GST_STATE_NULL);
gst_object_unref(GST_OBJECT (videodevicesrc));
