Class Method Details

.list ⇒ GLib::List<Gst::TypeFindFactory>

Gets the list of all registered typefind factories. You must free the list using gst_plugin_feature_list_free().

The returned factories are sorted by highest rank first, and then by factory name.

Returns:

Instance Method Details

#call_function(find) ⇒ nil

Calls the Gst::TypeFindFunction associated with this factory.

Parameters:

  • find (Gst::TypeFind) —

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

Returns:

  • (nil)

#caps ⇒ Gst::Caps

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

Returns:

  • (Gst::Caps) —

    the Gst::Caps associated with this factory

#extensions ⇒ Array<String>

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 g_strdupv(). This function may return nil to indicate a 0-length list.

Returns:

  • (Array<String>) —

    an array of extensions associated with this factory

#extensions_raw ⇒ Array<String>

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 g_strdupv(). This function may return nil to indicate a 0-length list.

Returns:

  • (Array<String>) —

    an array of extensions associated with this factory




# File 'lib/gst/type-find-factory.rb', line 19

#has_function ⇒ Boolean

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:

  • (Boolean) —

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