| 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<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 nullptr to indicate a 0-length list.
nullptr-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.

| GstTypeFindFactory* Gst::TypeFindFactory::gobj_copy | ( | ) |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
| bool Gst::TypeFindFactory::has_function | ( | ) | const |
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.
true if the factory has a typefind functions set, otherwise false.
