| 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.

| bool Gst::PluginFeature::check_version | ( | guint | min_major, |
| guint | min_minor, | ||
| guint | min_micro | ||
| ) | const |
Checks whether the given plugin feature is at least the required version.
| min_major | Minimum required major version. |
| min_minor | Minimum required minor version. |
| min_micro | Minimum required micro version. |
true if the plugin feature has at least the required version, otherwise false. | Glib::RefPtr<Gst::Plugin> Gst::PluginFeature::get_plugin | ( | ) | const |
Get the plugin that provides this feature.
nullptr. Unref with Gst::Object::unref() when no longer needed. | Glib::ustring Gst::PluginFeature::get_plugin_name | ( | ) | const |
Get the name of the plugin that provides this feature.
nullptr if the feature is not associated with a plugin. | guint Gst::PluginFeature::get_rank | ( | ) | const |
Gets the rank of a plugin feature.
|

Provides access to the underlying C GObject.
| GstPluginFeature* Gst::PluginFeature::gobj_copy | ( | ) |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
| Glib::RefPtr<Gst::PluginFeature> Gst::PluginFeature::load | ( | ) |
Loads the plugin containing feature if it's not already loaded.
feature is unaffected; use the return value instead.
Normally this function is used like this:
[C example ellipted]
nullptr on error.
|
noexcept |
| 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. |
