	SlotContext (YUVTEX statictex, YUVShader shader)
	Default constructor.

	~SlotContext ()
	Default destructor.

	ban_copy_ctor (SlotContext)

	ban_copy_asm (SlotContext)

void	activate (BitmapPars bmpars)
	Allocate SlotContext::yuvtex (for a frame of certain size)

void	deActivate ()
	Deallocate textures.

void	loadYUVFrame (YUVFrame *yuvframe)
	Load bitmap from YUVFrame to SlotContext::yuvtex.

YUVTEX *	getTEX ()
	Returns the relevant texture set (static or live)

bool	manageTimer (long int mstime)
	Updates SlotContext::lastmstime. Returns false if too little time has passed since receiving the last frame.

void	checkIfDead (long int mstime)
	Compares SlotContext::lastmstime to mstime and changes the state of SlotContext::is_dead.

bool	isPending (long int mstime)
	Compares SlotContext::lastmstime to mstime and returns true of a treshold is met (if last frame was received long time ago)

bool	isUsed () const

bool	isActive () const
	Check if active.

bool	isDead () const

Public Attributes
YUVTEX *	yuvtex
	This could be a base class for different kinds of textures (now only YUVTEX)

YUVTEX *	statictex
	A static texture to be shown on the screen if no video is received.

YUVShader *	shader
	Base class for the chosen Shader for this slot. Now always YUVShader.

BitmapPars	bmpars

long int	lastmstime
	Last millisecond timestamp when this slot received a frame.

Private Attributes
uint	ref_count

bool	active
	Is activated or not. Active = has received a setup frame.

bool	is_dead
	Has received frames or not for a while ?

AVCodecID	codec_id
	FFmpeg codec id.

bool	load_flag
	This flag is cleared when a new frame is loaded.

bool	keep_flag
	Should we keep on showing the previous frame, even if the slot is_dead?

long int	prev_mstimestamp
	for debugging: check if frames are fed in correct timestamp order

Detailed Description

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

Slot number identifies the origin of the stream. When the bitmap Frame arrives to OpenGLThread, each stream/slot requires:

This class encapsulates all that. SlotContext can be in an active (with textures reserved and shaders set) or in an inactive state.

The documentation for this class was generated from the following files:
