## Signals

### create-element

    GstElement *
    create_element_callback (GstElement * param_0,
                             gpointer udata)

    def create_element_callback (param_0, udata):
        #python callback for the 'create-element' signal

    function create_element_callback(param_0: GstElement * param_0, udata: gpointer udata): {
        // javascript callback for the 'create-element' signal
    }

Parameters:

`param_0` –
No description available
`udata` –

Returns (GstElement *) –

Flags: Run Last

## Properties

### context

    “context” GstGLContext *

Get OpenGL context

Flags : Read

### force-live

    “force-live” gboolean

Causes the element to aggregate on a timeout even when no live source is connected to its sinks. See min-upstream-latency for a companion property: in the vast majority of cases where you plan to plug in live sources with a non-zero latency, you should set it to a non-zero value.

Flags : Read / Write / Construct Only

Default value : false

Since : 1.24

### latency

    “latency” guint64

Additional latency in live mode to allow upstream to take longer to produce buffers for the current position (in nanoseconds)

Flags : Read / Write

Default value : 0

### min-upstream-latency

    “min-upstream-latency” guint64

Force minimum upstream latency (in nanoseconds). When sources with a higher latency are expected to be plugged in dynamically after the aggregator has started playing, this allows overriding the minimum latency reported by the initial source(s). This is only taken into account when larger than the actually reported minimum latency.

Flags : Read / Write

Default value : 0

Since : 1.24

### mixer

    “mixer” GstElement *

The GL mixer chain to use

Flags : Read / Write

### start-time

    “start-time” guint64

Start time to use if start-time-selection=set

Flags : Read / Write

Default value : 0

### start-time-selection

    “start-time-selection” Glmixer-bin-start-time-selection *

Decides which start time is output

Flags : Read / Write

Default value : zero (0)

## Named constants

### Glmixer-bin-start-time-selection

#### Members

`zero` (0) – Start at 0 running time (default)
`first` (1) – Start at first observed input running time
`set` (2) – Set start time with start-time property
