## Property Details

### The `“latency”` property

      “latency”                  guint64

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

Owner: GstGLMixerBin

Flags: Read / Write

Default value: 0

### The `“mixer”` property

      “mixer”                    GstElement *

The GL mixer chain to use.

Owner: GstGLMixerBin

Flags: Read / Write

### The `“start-time”` property

      “start-time”               guint64

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

Owner: GstGLMixerBin

Flags: Read / Write

Default value: 18446744073709551615

### The `“start-time-selection”` property

      “start-time-selection”     GstGLMixerBinStartTimeSelection

Decides which start time is output.

Owner: GstGLMixerBin

Flags: Read / Write

Default value: Start at 0 running time (default)

## Signal Details

### The `“create-element”` signal

    GstElement*
    user_function (GstGLMixerBin *gstglmixerbin,
