+ * @start: Start processing. Subclasses should open resources and prepare
+ *    to produce data.
+ * @stop: Stop processing. Subclasses should use this to close resources.
+ * @get_times: Given a buffer, return the start and stop time when it 
+ *    should be pushed out. The base class will sync on the clock using 
+ *    these times. 
+ * @get_size: Return the total size of the resource, in the configured format.
+ * @is_seekable: Check if the source can seek
+ * @unlock: Unlock any pending access to the resource. Subclasses should
+ *    unblock any blocked function ASAP
+ * @unlock_stop: Clear the previous unlock request. Subclasses should clear
+ *    any state they set during unlock(), such as clearing command queues. 
+ * @event: Override this to implement custom event handling.
+ * @create: Ask the subclass to create a buffer with offset and size.
+ * @do_seek: Perform seeking on the resource to the indicated segment.
+ * @prepare_seek_segment: Prepare the GstSegment that will be passed to the 
+ *   do_seek vmethod for executing a seek request. Sub-classes should override 
+ *   this if they support seeking in formats other than the configured native 
+ *   format. By default, it tries to convert the seek arguments to the 
+ *   configured native format and prepare a segment in that format.
+ *   Since: 0.10.13
+ * @query: Handle a requested query. 
+ * @check_get_range: Check whether the source would support pull-based 
+ *   operation if it were to be opened now. This vfunc is optional, but 
+ *   should be implemented if possible to avoid unnecessary start/stop 
+ *   cycles. The default implementation will open and close the resource 
+ *   to find out whether get_range is supported, and that is usually 
+ *   undesirable. 
+ * @fixate: Called during negotation if caps need fixating. Implement instead of
+ *   setting a fixate function on the source pad.
+ *
+ * Subclasses can override any of the available virtual methods or not, as
+ * needed. At the minimum, the @create method should be overridden to produce
