Signals
void	frameAvailable ()
	The signal is emitted whenever a new frame is available and a subsequent call to swapBuffers() will not block and return true.

Public Member Functions
virtual	~VideoSink ()
const QMatrix4x4 &	transformationMatrix () const
	Queries the 4x4 transformation matrix for the current frame.
virtual bool	swapBuffers ()=0
	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.

Protected Member Functions
	VideoSink (VideoSinkPrivate *d, QObject *parent=nullptr)

swapBuffers()

virtual bool lomiri::MediaHub::VideoSink::swapBuffers ( )

pure virtual

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.

Implemented in lomiri::MediaHub::EglVideoSink, lomiri::MediaHub::HybrisVideoSink, and NullVideoSink.
