Collaboration diagram for opengl:

Classes
class	YUVFrame
	A GPU YUV frame. More...

struct	OpenGLFrameFifoContext
	Describes the stack structure and fifo behaviour for an OpenGLFrameFifo. More...

class	OpenGLFrameFifo
	A FrameFifo managed and used by OpenGLThread. More...

class	SlotContext
	Each Frame carries information about it's slot number in Frame::slot. More...

class	RenderContext
	Encapsulates data for rendering a single bitmap: vertex array object (VAO), vertex buffer object (VBO), vertice coordinates, transformation matrix, etc. More...

class	RenderGroup
	Group of bitmaps that are rendered into the same X-window. More...

class	OpenGLThread
	This class does a lot of things: More...

class	TEX
	A class encapsulating information about an OpenGL texture set (sizes, OpenGL reference ids, etc.) More...

class	YUVTEX
	A class encapsulating information about an OpenGL texture set for a YUV pixmap (sizes, OpenGL reference ids, etc.) More...

struct	OpenGLSignalPars
	Signal information for OpenGLThread. More...

struct	OpenGLSignalContext
	Encapsulates data sent by the signal. More...

Enumerations
enum class	OpenGLSignal { none , exit , info , new_render_group , del_render_group , new_render_context , del_render_context , new_rectangle , clear_objects }
	Signals used by OpenGLThread. More...

int	readbytes (const char fname, char &buffer)

int	readyuvbytes (const char fname, GLubyte &Y, GLubyte &U, GLubyte &V)
	Auxiliary routine for testing.

void	zeroyuvbytes (int ysize, GLubyte &Y, GLubyte &U, GLubyte *&V)
	Auxiliary routine for testing.

void	getPBO (GLuint &index, GLsizei size, GLubyte *&payload)
	Get PBO from the GPU. There are two versions of this function: other one can be enabled in source for valgrind debugging.

void	releasePBO (GLuint index, GLubyte payload)

void	getTEX (GLuint &index, GLint internal_format, GLint format, GLsizei w, GLsizei h)
	Get texture from the GPU.
