| typedef sigc::slot< bool, const Glib::RefPtr<Gst::PluginFeature>& > Gst::PluginFeature::SlotFilter |
For example, bool on_filter(const Glib::RefPtr<Gst::PluginFeature>& feature);.
The filter function should return true if the feature is a match, false otherwise.

| min_major | Minimum required major version. |
| min_minor | Minimum required minor version. |

true if the plugin feature has at least the required version, otherwise #false. | Glib::RefPtr<Gst::Plugin> Gst::PluginFeature::get_plugin | ( | ) | const |

feature is unaffected; use the return value instead.
Normally this function is used like this:

0 on error. | void Gst::PluginFeature::set_rank | ( | guint | rank | ) |
Specifies a rank for a plugin feature, so that autoplugging uses the most appropriate feature.
| rank | Rank value - higher number means more priority rank. |
