Public Member Functions
	OpenGLFrameFifo (OpenGLFrameFifoContext ctx=OpenGLFrameFifoContext())
	Default constructor.
	~OpenGLFrameFifo ()
	Default destructor.
virtual bool	writeCopy (Frame *f, bool wait=false)
	Redefined. Uses FrameFifo::writeCopy. Separates configuration frames and YUVFrames.
virtual void	recycle_ (Frame *f)
	Redefined. Uses FrameFifo::recycle_. Separates configuration frames and YUVFrames.
void	allocateYUV ()
	Allocate YUVFrame's .. must be done after OpenGLThread has been started.
void	deallocateYUV ()
	Deallocate YUVFrame's .. must be done before OpenGLThread exits.
void	dumpYUVStacks ()
	Dump frames in OpenGLFrameFifo::yuv_stacks.
void	YUVdiagnosis ()
	Brief resumen of OpenGLFrameFifo::yuv_stacks.

	ban_copy_asm (FrameFifo)
Reservoir &	getReservoir (FrameClass cl)
	Get the reservoir .. in the case you want to manipulate the frames.
virtual Frame *	read (unsigned short int mstimeout=0)
	Pop a frame from the end of the fifo when available.
virtual void	recycle (Frame *f)
	Like FrameFifo::recycle_ but with mutex protection.
virtual void	recycleAll ()
	Recycle all frames from fifo back to stack (make a "flush")
virtual void	dumpStacks ()
	Dump frames in the stacks.
virtual void	dumpFifo ()
	Dump frames in the fifo.
virtual void	diagnosis ()
	Print a resumen of fifo and stack usage.
bool	isEmpty ()
	Tell if fifo is empty.

Protected Member Functions
YUVFrame *	prepareAVBitmapFrame (AVBitmapFrame *frame)
	Tries to get a YUVFrame with correct bitmap dimensions from the stack. If success, returns pointer to the YUVFrame, otherwise NULL.
Protected Member Functions inherited from FrameFifo
virtual void	recycleAll_ ()
