Calls the #GstTypeFindFunction associated with this factory.
Gets the #GstCaps associated with a typefind factory.
Gets the extensions associated with a #GstTypeFindFactory. The returned array should not be changed. If you need to change stuff in it, you should copy it using glib.global.strdupv. This function may return null to indicate a 0-length list.
Check whether the factory has a typefind function. Typefind factories without typefind functions are a last-effort fallback mechanism to e.g. assume a certain media type based on the file extension.
Gets the list of all registered typefind factories. You must free the list using gst.plugin_feature.PluginFeature.listFree.
Copies the list of features. Caller should call gst_plugin_feature_list_free when done with the list.
Debug the plugin feature names in list.
Compares the two given #GstPluginFeature instances. This function can be used as a #GCompareFunc when sorting by rank and then by name.
Checks whether the given plugin feature is at least the required version.
Get the plugin that provides this feature.
Get the name of the plugin that provides this feature.
Gets the rank of a plugin feature.
Loads the plugin containing feature if it's not already loaded. feature is unaffected; use the return value instead.
Specifies a rank for a plugin feature, so that autoplugging uses the most appropriate feature.
These functions allow querying information about registered typefind functions. How to create and register these functions is described in the section <link linkend="gstreamer-Writing-typefind-functions"> "Writing typefind functions"</link>.
The following example shows how to write a very simple typefinder that identifies the given data. You can get quite a bit more complicated than that though.
