DirectControlBinding

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.

class DirectControlBinding : ControlBinding {

this(gst.object.ObjectGst object, string propertyName, gst.control_source.ControlSource cs);

static gstcontroller.direct_control_binding.DirectControlBinding newAbsolute(gst.object.ObjectGst object, string propertyName, gst.control_source.ControlSource cs);

}

Constructors

this this(gst.object.ObjectGst object, string propertyName, gst.control_source.ControlSource cs): Create a new control-binding that attaches the #GstControlSource to the #GObject 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.

Members

Static functions

newAbsolute gstcontroller.direct_control_binding.DirectControlBinding newAbsolute(gst.object.ObjectGst object, string propertyName, gst.control_source.ControlSource cs): Create a new control-binding that attaches the #GstControlSource to the #GObject property. It will directly map the control source values to the target property range without any transformations.

Inherited Members

From ControlBinding

getGValueArray bool getGValueArray(gst.types.ClockTime timestamp, gst.types.ClockTime interval, gobject.value.Value[] values): Gets a number of #GValues for the given controlled property starting at the requested time. The array values need to hold enough space for n_values of #GValue.
getValue gobject.value.Value getValue(gst.types.ClockTime timestamp): Gets the value for the given controlled property at the requested time.
isDisabled bool isDisabled(): Checks if the control binding is disabled.
setDisabled void setDisabled(bool disabled): This function is used to disable a control binding for some time, i.e. gst.object.ObjectGst.syncValues will do nothing.
syncValues bool syncValues(gst.object.ObjectGst object, gst.types.ClockTime timestamp, gst.types.ClockTime lastSync): Sets the property of the object, according to the #GstControlSources that handles it and for the given timestamp.
