Sets our main struct and passes it to the parent class.

Add the given stream to the collection.
Get the number of streams this collection contains
Retrieve the gstreamer.Stream with index index from the collection.

Returns the upstream id of the collection.

Checks to see if there is any object named name in list. This function does not do any locking of any kind. You might want to protect the provided list with the lock of the owner of the list. This function will lock each GstObject in the list to compare the name, so be careful when passing a list with a locked object.
A default deep_notify signal callback for an object. The user data should contain a pointer to an array of strings that should be excluded from the notify. The default handler will print the new value of the property using g_print.
Increase the reference count of object, and possibly remove the floating reference, if object has a floating reference.
Atomically modifies a pointer to point to a new object. The reference count of oldobj is decreased and the reference count of newobj is increased.
Attach the gstreamer.ControlBinding to the object. If there already was a gstreamer.ControlBinding for this property it will be replaced.
A default error function that uses g_printerr() to display the error message and the optional debug string..
Gets the corresponding gstreamer.ControlBinding for the property. This should be unreferenced again after use.
Obtain the control-rate for this object. Audio processing gstreamer.Element objects will use this rate to sub-divide their processing loop and call gst_object_sync_values() in between. The length of the processing segment should be up to control-rate nanoseconds.
Gets a number of gobject.Values for the given controlled property starting at the requested time. The array values need to hold enough space for n_values of gobject.Value
Returns a copy of the name of object. Caller should g_free() the return value after usage. For a nameless object, this returns NULL, which you can safely g_free() as well.
Returns the parent of object. This function increases the refcount of the parent object so you should gst_object_unref() it after usage.
Generates a string describing the path of object in the object hierarchy. Only useful (or used) for debugging.
Gets the value for the given controlled property at the requested time.
Gets a number of values for the given controlled property starting at the requested time. The array values need to hold enough space for n_values of the same type as the objects property's type.
Check if the object has active controlled properties.
Check if object has an ancestor ancestor somewhere up in the hierarchy. One can e.g. check if a gstreamer.Element is inside a gstreamer.Pipeline
Check if object has an ancestor ancestor somewhere up in the hierarchy. One can e.g. check if a gstreamer.Element is inside a gstreamer.Pipeline
Check if parent is the parent of object. E.g. a gstreamer.Element can check if it owns a given gstreamer.Pad
Increments the reference count on object. This function does not take the lock on object because it relies on atomic refcounting.
Removes the corresponding gstreamer.ControlBinding If it was the last ref of the binding, it will be disposed.
This function is used to disable the control bindings on a property for some time, i.e. gst_object_sync_values() will do nothing for the property.
This function is used to disable all controlled properties of the object for some time, i.e. gst_object_sync_values() will do nothing.
Change the control-rate for this object. Audio processing gstreamer.Element objects will use this rate to sub-divide their processing loop and call gst_object_sync_values() in between. The length of the processing segment should be up to control-rate nanoseconds.
Sets the name of object, or gives object a guaranteed unique name (if name is NULL). This function makes a copy of the provided name, so the caller retains ownership of the name it sent.
Sets the parent of object to parent. The object's reference count will be incremented, and any floating reference will be removed (see gst_object_ref_sink()).
Returns a suggestion for timestamps where buffers should be split to get best controller results.
Sets the properties of the object, according to the gstreamer.ControlSources that (maybe) handle them and for the given timestamp.
Clear the parent of object, removing the associated reference. This function decreases the refcount of object.
Decrements the reference count on object. If reference count hits zero, destroy object. This function does not take the lock on object as it relies on atomic refcounting.
The deep notify signal is used to be notified of property changes. It is typically attached to the toplevel bin to receive notifications from all the elements contained in that bin.
A collection of gstreamer.Stream that are available.
A gstreamer.StreamCollection will be provided by elements that can make those streams available. Applications can use the collection to show the user what streams are available by using gst_stream_collection_get_stream()
Once posted, a gstreamer.StreamCollection is immutable. Updates are made by sending a new gstreamer.StreamCollection message, which may or may not share some of the gstreamer.Stream objects from the collection it replaces. The receiver can check the sender of a stream collection message to know which collection is obsoleted.
Several elements in a pipeline can provide gstreamer.StreamCollection
Applications can activate streams from a collection by using the GST_EVENT_SELECT_STREAMS event on a pipeline, bin or element.
