+ * This function returns the media pipeline that an entity has been associated

+ *
+ * In general, entities can be part of multiple pipelines, when carrying
+ * multiple streams (either on different pads, or on the same pad using
+ * multiplexed streams). This function is to be used only for entities that
+ * do not support multiple pipelines.
+ *
+ * Return: The media_pipeline the entity is part of, or NULL if the entity is
+ * not part of any pipeline.
