Collaboration diagram for NullVideoSink:

Public Member Functions
	NullVideoSink (QObject *parent)
bool	swapBuffers () override
	Releases the current buffer, and consumes the next buffer in the queue, making it available for consumption by consumers of this API in an implementation-specific way. Clients will usually rely on a GL texture to receive the latest buffer.
Public Member Functions inherited from lomiri::MediaHub::VideoSink
virtual	~VideoSink ()
const QMatrix4x4 &	transformationMatrix () const
	Queries the 4x4 transformation matrix for the current frame.

Additional Inherited Members
Signals inherited from lomiri::MediaHub::VideoSink
void	frameAvailable ()
	The signal is emitted whenever a new frame is available and a subsequent call to swapBuffers() will not block and return true.
Protected Member Functions inherited from lomiri::MediaHub::VideoSink
	VideoSink (VideoSinkPrivate *d, QObject *parent=nullptr)
