# uridecodebin3

Decodes data from a URI into raw media. It selects a source element that can handle the given uri scheme and connects it to a decodebin3.

## Signals

### about-to-finish

    about_to_finish_callback (GstElement * param_0,
                              gpointer udata)

    def about_to_finish_callback (param_0, udata):
        #python callback for the 'about-to-finish' signal

    function about_to_finish_callback(param_0: GstElement * param_0, udata: gpointer udata): {
        // javascript callback for the 'about-to-finish' signal
    }

This signal is emitted when the data for the selected URI is entirely buffered and it is safe to specify another URI.

`param_0` –

`udata` –

### select-stream

    gint
    select_stream_callback (GstElement * decodebin,
                            GstStreamCollection * collection,
                            GstStream * stream,
                            gpointer udata)

    def select_stream_callback (decodebin, collection, stream, udata):
        #python callback for the 'select-stream' signal

    function select_stream_callback(decodebin: GstElement * decodebin, collection: GstStreamCollection * collection, stream: GstStream * stream, udata: gpointer udata): {
        // javascript callback for the 'select-stream' signal
    }

This signal is emitted whenever decodebin needs to decide whether to expose a stream of a given collection.

Note that the prefered way to select streams is to listen to GST_MESSAGE_STREAM_COLLECTION on the bus and send a GST_EVENT_SELECT_STREAMS with the streams the user wants.

Parameters:

`decodebin` –

a uridecodebin3

`collection` –

a GstStreamCollection

`stream` –

a GstStream

`udata` –
No description available
Returns (gint) –

1 if the stream should be selected, 0 if it shouldn't be selected. A value of -1 (default) lets decodebin decide what to do with the stream.

Flags: Run Last

### source-setup

    source_setup_callback (GstElement * bin,
                           GstElement * source,
                           gpointer udata)

    def source_setup_callback (bin, source, udata):
        #python callback for the 'source-setup' signal

    function source_setup_callback(bin: GstElement * bin, source: GstElement * source, udata: gpointer udata): {
        // javascript callback for the 'source-setup' signal
    }

This signal is emitted after a source element has been created, so it can be configured by setting additional properties (e.g. set a proxy server for an http source, or set the device and read speed for an audio cd source).

Parameters:

`bin` –

the uridecodebin.

`source` –

source element

`udata` –
