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
- possible formats on sink and source pad implemented
with custom transform_caps function. By default uses
same format on sink and source.
- 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
GstPushSrc
Base class for push based source elements
