Struct gstreamer_controller::LFOControlSource[][src]

pub struct LFOControlSource(_);
Expand description

LFOControlSource is a gst::ControlSource, that provides several periodic waveforms as control values.

To use LFOControlSource get a new instance by calling new(), bind it to a GParamSpec and set the relevant properties.

All functions are MT-safe.

Implements

LFOControlSourceExt, gst::prelude::ControlSourceExt, gst::prelude::ObjectExt

Implementations

This returns a new, unbound LFOControlSource.

Returns

This method returns an Ordering between self and other. Read more

Compares and returns the maximum of two values. Read more

Compares and returns the minimum of two values. Read more

Restrict a value to a certain interval. Read more

This method tests for self and other values to be equal, and is used by ==. Read more

This method tests for !=.

This method returns an ordering between self and other values if one exists. Read more

This method tests less than (for self and other) and is used by the < operator. Read more

This method tests less than or equal to (for self and other) and is used by the <= operator. Read more

Upcasts an object to a superclass or interface T. Read more

Upcasts an object to a reference of its superclass or interface T. Read more

Tries to downcast to a subclass or interface implementor T. Read more

Tries to downcast to a reference of its subclass or interface implementor T. Read more

Tries to cast to an object of type T. This handles upcasting, downcasting and casting between interface and interface implementors. All checks are performed at runtime, while downcast and upcast will do many checks at compile-time already. Read more

Tries to cast to reference to an object of type T. This handles upcasting, downcasting and casting between interface and interface implementors. All checks are performed at runtime, while downcast and upcast will do many checks at compile-time already. Read more

Casts to T unconditionally. Read more

Casts to &T unconditionally. Read more

Gets the value for this ControlSource at a given timestamp. Read more

Performs the conversion.

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 a copy of the name of self. Caller should g_free() the return value after usage. For a nameless object, this returns None, which you can safely g_free() as well. 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

Performs the conversion.

Returns true if the object is an instance of (can be cast to) T.
