pub fn add_control_binding<P>(&self, binding: &P) -> Result<(), BoolError> where
P: IsA<ControlBinding>,
[src]Attach the ControlBinding
to the object. If there already was a
ControlBinding
for this property it will be replaced. Read more
A default error function that uses g_printerr()
to display the error message
and the optional debug string.. Read more
Gets the corresponding ControlBinding
for the property. This should be
unreferenced again after use. Read more
Obtain the control-rate for this self
. Audio processing Element
objects will use this rate to sub-divide their processing loop and call
sync_values()
in between. The length of the processing segment
should be up to control
-rate nanoseconds. Read more
Returns the parent of self
. This function increases the refcount
of the parent object so you should gst_object_unref()
it after usage. Read more
Generates a string describing the path of self
in
the object hierarchy. Only useful (or used) for debugging. Read more
Gets the value for the given controlled property at the requested time. Read more
