A class used to get information about registered typefind functions.
The methods in this class allow querying information about registered typefind functions.
Writing typefinders in C++ is not possible presently.

virtual |
void Gst::TypeFindFactory::call_slot | ( | Gst::TypeFind& | find | ) |
Calls the Gst::TypeFind::SlotFind associated with this factory.
find | A properly setup Gst::TypeFind entry. The get_data and suggest_type members must be set. |
Glib::RefPtr<Gst::Caps> Gst::TypeFindFactory::get_caps | ( | ) |
Glib::RefPtr<const Gst::Caps> Gst::TypeFindFactory::get_caps | ( | ) | const |
std::vector<Glib::ustring> Gst::TypeFindFactory::get_extensions | ( | ) | const |
Gets the extensions associated with a Gst::TypeFindFactory.
The returned array should not be changed. If you need to change stuff in it, you should copy it using Glib::strdupv(). This function may return 0
to indicate a 0-length list.
0
-terminated array of extensions associated with this factory.
|
static |
Gets the list of all registered typefind factories.
You must free the list using Gst::PluginFeature::list_free().
The returned factories are sorted by highest rank first, and then by factory name.
Free-function: gst_plugin_feature_list_free
