Class Details¶

class GstController.DirectControlBinding(**kwargs)¶

Bases:: Gst.ControlBinding
Abstract:: No
Structure:: GstController.DirectControlBindingClass

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.

classmethod new(object, property_name, cs)[source]¶

Parameters:

object (Gst.Object) – the object of the property
property_name (str) – the property-name to attach the control source
cs (Gst.ControlSource) – the control source

Returns:

the new GstController.DirectControlBinding

Return type:

Gst.ControlBinding

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.

classmethod new_absolute(object, property_name, cs)[source]¶

Parameters:

object (Gst.Object) – the object of the property
property_name (str) – the property-name to attach the control source
cs (Gst.ControlSource) – the control source

Returns:

the new GstController.DirectControlBinding

Return type:

Gst.ControlBinding

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.

New in version 1.6.
