	Default constructor. More...

virtual void	flush ()
	Reset decoder state. How to flush depends on the decoder library.

Public Member Functions inherited from Decoder
	Decoder ()
	Default constructor.

virtual	~Decoder ()
	Default destructor.

void	input (Frame *f)
	Create a copy of the frame into the internal storage of the decoder (i.e. to Decoder::in_frame)

	< Return in_frame timestamp More...

virtual void	releaseOutput ()
	Decoder might want to know that it's ok to overwrite the frame.

virtual bool	pull ()=0
	Decode in_frame to out_frame. Return true if decoder returned a new frame (into out_frame), otherwise false. Implementation depends on the decoder library.

virtual bool	isOk ()
	The thread that uses this decoder can check if it has gone sour.

bool	hasFrame ()
