Detailed Description

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.

Member Function Documentation

◆ call_slot()

void Gst::TypeFindFactory::call_slot ( Gst::TypeFind& find )

Calls the Gst::TypeFind::SlotFind associated with this factory.

Parameters

find	A properly setup Gst::TypeFind entry. The get_data and suggest_type members must be set.

◆ get_caps() [1/2]

Glib::RefPtr<Gst::Caps> Gst::TypeFindFactory::get_caps ( )

Gets the Gst::Caps associated with a typefind factory.

Returns: The Gst::Caps associated with this factory.

◆ get_caps() [2/2]

Glib::RefPtr<const Gst::Caps> Gst::TypeFindFactory::get_caps ( ) const

Gets the Gst::Caps associated with a typefind factory.

Returns: The Gst::Caps associated with this factory.

◆ get_extensions()

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.

Returns: A nullptr-terminated array of extensions associated with this factory.

◆ get_list()

static Glib::ListHandle< Glib::RefPtr<Gst::TypeFindFactory> > Gst::TypeFindFactory::get_list ( )

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

Returns: The list of all registered Gst::TypeFindFactory.

◆ get_type()

static GType Gst::TypeFindFactory::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

◆ gobj() [1/2]

GstTypeFindFactory* Gst::TypeFindFactory::gobj ( )

inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

const GstTypeFindFactory* Gst::TypeFindFactory::gobj ( ) const

inline

Provides access to the underlying C GObject.

◆ gobj_copy()

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.

◆ has_function()

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.

Returns: true if the factory has a typefind functions set, otherwise false.

◆ operator=()

TypeFindFactory& Gst::TypeFindFactory::operator= ( TypeFindFactory&& src )
