This function is used to disable the control bindings on a property for some time, i.e. GstObjectExt::sync_values will do nothing for the property. ## property_name property to disable ## disabled boolean that specifies whether to disable the controller or not. Read more
fn set_control_bindings_disabled(&self, disabled: bool)[src][−]
This function is used to disable all controlled properties of the self for some time, i.e. GstObjectExt::sync_values will do nothing. ## disabled boolean that specifies whether to disable the controller or not. Read more
fn set_control_rate(&self, control_rate: ClockTime)[src][−]
Change the control-rate for this self. Audio processing Element objects will use this rate to sub-divide their processing loop and call GstObjectExt::sync_values in between. The length of the processing segment should be up to control-rate nanoseconds. Read more
fn set_name(&self, name: &str) -> Result<(), BoolError>[src][−]
Sets the name of self, or gives self a guaranteed unique name (if name is None). This function makes a copy of the provided name, so the caller retains ownership of the name it sent. ## name new name of object Read more
fn set_parent<P>(&self, parent: &P) -> Result<(), BoolError> where
P: IsA<Object>, [src][−]
P: IsA<Object>,
Sets the parent of self to parent. The object's reference count will be incremented, and any floating reference will be removed (see Object::ref_sink). ## parent new parent of object Read more
fn suggest_next_sync(&self) -> ClockTime[src][−]
Returns a suggestion for timestamps where buffers should be split to get best controller results. Read more
fn sync_values(&self, timestamp: ClockTime) -> Result<(), BoolError>[src][−]
Sets the properties of the object, according to the GstControlSources that (maybe) handle them and for the given timestamp. Read more
fn unparent(&self)[src][−]
Clear the parent of self, removing the associated reference. This function decreases the refcount of self. Read more
