GstBin Base container element GstBin is the simplest of the container elements, allowing elements to become children of itself. Pads from the child elements can be ghosted to the bin, making the bin itself look transparently like any other element, allowing for deep nesting of predefined sub-pipelines. A new GstBin is created with gst_bin_new(). Use a #GstPipeline instead if you want to create a toplevel bin because a normal bin doesn't have a scheduler of its own. After the bin has been created you will typically add elements to it with gst_bin_add(). You can remove elements with gst_bin_remove(). An element can be retrieved from a bin with gst_bin_get_by_name(), using the elements name. gst_bin_get_by_name_recurse_up() is mainly used for internal purposes and will query the parent bins when the element is not found in the current bin. The list of elements in a bin can be retrieved with gst_bin_get_list(). After the bin has been set to the PLAYING state (with gst_element_set_state()), gst_bin_iterate() is used to process the elements in the bin. The "element_added" signal is fired whenever a new element is added to the bin. The "element_removed" signal is fired whenever an element is removed from the bin. gst_bin_destroy() is used to destroy the bin. To control the selection of the clock in a bin, you can use the following methods: gst_bin_auto_clock() to let the bin select a clock automatically, gst_bin_get_clock() to get the current clock of the bin and gst_bin_use_clock() to specify a clock explicitly. Note that the default behaviour is to automatically select a clock from one of the clock providers in the bin. Flags for a bin. @GST_BIN_FLAG_MANAGER: This bin has a scheduler and can be used as a toplevel bin. @GST_BIN_SELF_SCHEDULABLE: This bin iterates itself, so no calls to gst_bin_iterate() should be made. @GST_BIN_FLAG_PREFER_COTHREADS: This bin preferes to have its elements scheduled with cothreads @GST_BIN_FLAG_FIXED_CLOCK: This bin uses a fixed clock, possibly the one set with gst_bin_use_clock(). @GST_BIN_FLAG_LAST: The GstBin object @gstbin: the object which received the signal. @arg1: the element that was added to the bin @gstbin: the object which received the signal. @arg1: the element that was removed from the bin This signal is emitted when a bin iterates, either automatically or due to a #gst_bin_iterate() call. The return value is used to determine if the object method handler processed any data. In most normal cases, a user-provided signal handler should return FALSE. @gstbin: the object which received the signal. @Returns: TRUE if the state of the bin was advanced. The signature of the callback for the post and pre iterate function as set with gst_bin_set_pre_iterate_function() and gst_bin_set_post_iterate_function(). @bin: The bin that performed the callback @user_data: user data @name: @Returns: @bin: @element: @bin: @element_1: @Varargs: @bin: @element: @bin: @element_1: @Varargs: @bin: @name: @Returns: @bin: @name: @Returns: @bin: @Returns: @bin: @Returns: @bin: @func: @user_data: @bin: @func: @user_data: @bin: @oldstate: @newstate: @child: @bin: @bin: @Returns: @bin: @clock:
