GstDirectControlBinding

A value mapping object that attaches control sources to gobject properties. It will map the control values directly to the target property range. If a non-absolute direct control binding is used, the value range [0.0 ... 1.0] is mapped to full target property range, and all values outside the range will be clipped. An absolute control binding will not do any value transformations.

GstController.DirectControlBinding.prototype.new 

function GstController.DirectControlBinding.prototype.new(object: Gst.Object, property_name: String, cs: Gst.ControlSource): {
    // javascript wrapper for 'gst_direct_control_binding_new'
}

Create a new control-binding that attaches the Gst.ControlSource to the GObject.Object property. It will map the control source range [0.0 ... 1.0] to the full target property range, and clip all values outside this range.

Parameters:

object (Gst.Object) –

the object of the property

property_name (String) –

the property-name to attach the control source

the control source

Returns (Gst.ControlBinding) –

the new GstController.DirectControlBinding

GstController.DirectControlBinding.prototype.new_absolute 

function GstController.DirectControlBinding.prototype.new_absolute(object: Gst.Object, property_name: String, cs: Gst.ControlSource): {
    // javascript wrapper for 'gst_direct_control_binding_new_absolute'
}

Create a new control-binding that attaches the Gst.ControlSource to the GObject.Object property. It will directly map the control source values to the target property range without any transformations.

Parameters:

object (Gst.Object) –

the object of the property

property_name (String) –

the property-name to attach the control source

the control source

Returns (Gst.ControlBinding) –

the new GstController.DirectControlBinding
