Create Gst::Element 's from a factory.
Gst::ElementFactory is used to create instances of elements. A Gst::ElementFactory can be added to a Gst::Plugin as it is also a Gst::PluginFeature.
Use the find() and create() functions to create element instances or use create_element() as a convenient shortcut.
The following code example shows you how to create a 'filesrc' element.
#include <gstreamermm.h>
int main (int argc, char *argc[])
{
if(!srcfactory)
{
exit(1);
}
src = srcfactory->create("src");
if(!src)
{
exit(1);
}
...
}
