------------
|
|
|
|
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
