Wim Taymans 8df6cd7243 Remove old query functions. Ported old code. Original commit message from CVS: Remove old query functions. Ported old code. Added position/convert helper functions to gstutils. Reordered gstpad.c code, grouping relevant things. Remove gst_message_new(), always need to speficy a specific message.		2005-05-09 10:53:13 +00:00

Base classes
------------

GstBaseSink
 
  Base class for sink elements.

  - one sinkpad
  - handles state changes
  - does flushing
  - preroll with optional preview
  - pull/push mode
  - EOS handling

  FIXME: not much point making it operate in pull mode as a generic
  base class I guess... 

GstBaseTransform

  Base class for simple tranform filters

  - one sinkpad and one srcpad
  - formats the same on sink and source pad.
  - handles state changes
  - does flushing
  - push mode
  - pull mode if transform can operate on arbitrary data

GstBaseSrc

  Base class for getrange based source elements

  - one sinkpad
  - handles state changes
  - pull/push mode
  - handles seeking/query
