Namespaces:

• Gst

Classes:

• ControlSource - The class structure of ControlSource.
• Controller -
• InterpolationControlSource - InterpolationControlSource is a ControlSource, that interpolates values between user-given control points. It supports several interpolation modes and property types. To use InterpolationControlSource get a new instance by calling InterpolationControlSource, bind it to a ParamSpec, select a interpolation mode with set_interpolation_mode and set some control points by calling set. All functions are MT-safe.
• LFOControlSource - LFOControlSource is a ControlSource, that provides several periodic waveforms as control values. It supports all fundamental, numeric GValue types as property. To use LFOControlSource get a new instance by calling LFOControlSource, bind it to a ParamSpec and set the relevant properties or use gst_lfo_control_source_set_waveform. All functions are MT-safe.
• TimedValue - Structure for saving a timestamp and a value.
• ValueArray - Structure to receive multiple values at once.

Enums:

• InterpolateMode - The various interpolation modes available.
• LFOWaveform - The various waveform modes available.

Delegates:

• public delegate bool ControlSourceBind (ControlSource _self, ParamSpec pspec)
• public delegate bool ControlSourceGetValue (ControlSource _self, ClockTime timestamp, Value value)
• public delegate bool ControlSourceGetValueArray (ControlSource _self, ClockTime timestamp, ValueArray value_array)

Methods:

• public weak Controller object_control_properties (Object object, ...)
  Convenience function for GObject Creates a GstController that allows you to dynamically control one, or more, GObject properties. If the given GObject already has a GstController, it adds the given properties to the existing controller and returns that controller. one or more of the given properties aren't available, or cannot be controlled, for the given element.
• public ClockTime object_get_control_rate (Object object)
  Obtain the control-rate for this object. Audio processing Element objects will use this rate to sub-divide their processing loop and call object_sync_values inbetween. The length of the processing segment should be up to control-rate nanoseconds. If the object is not under property control, this will return CLOCK_TIME_NONE. This allows the element to avoid the sub-dividing. The control-rate is not expected to change if the element is in PAUSED or PLAYING.
• public weak ControlSource object_get_control_source (Object object, string property_name)
  Gets the corresponding ControlSource for the property. This should be unreferenced again after use. controlled by this controller or no ControlSource was assigned yet.
• public weak Controller object_get_controller (Object object)
  Gets the controller for the given GObject
• public bool object_get_value_array (Object object, ClockTime timestamp, ValueArray value_array)
  Function to be able to get an array of values for one element properties If the GstValueArray-> values array is NULL, it will be created by the function. The type of the values in the array are the same as the property's type. The g_object_* functions are just convenience functions for GObject
• public bool object_get_value_arrays (Object object, ClockTime timestamp, SList<ValueArray> value_arrays)
  Function to be able to get an array of values for one or more given element properties. If the GstValueArray->values array in list nodes is NULL, it will be created by the function. The type of the values in the array are the same as the property's type. The g_object_* functions are just convenience functions for GObject
• public void object_set_control_rate (Object object, ClockTime control_rate)
  Change the control-rate for this object. Audio processing Element objects will use this rate to sub-divide their processing loop and call object_sync_values inbetween. The length of the processing segment should be up to control-rate nanoseconds. The control-rate should not change if the element is in PAUSED or PLAYING.
• public bool object_set_control_source (Object object, string property_name, ControlSource csource)
  Sets the ControlSource for property_name . If there already was a ControlSource for this property it will be unreferenced. couldn't be bound to the property, true if everything worked as expected.
• public bool object_set_controller (Object object, Controller controller)
  Sets the controller on the given GObject
• public ClockTime object_suggest_next_sync (Object object)
  Convenience function for GObject
• public bool object_sync_values (Object object, ClockTime timestamp)
  Convenience function for GObject
• public bool object_uncontrol_properties (Object object, ...)
  Convenience function for GObject Removes the given element's properties from it's controller controller, true otherwise
