Public Member Functions
	FrameCache (const char *name, FrameCacheContext ctx=FrameCacheContext())

	ban_copy_ctor (FrameCache)

	ban_copy_asm (FrameCache)

long int	getMinTime_ ()

long int	getMaxTime_ ()

bool	hasDeltaFrames ()

virtual bool	writeCopy (Frame *f, bool wait=false)
	Take a frame "ftmp" from the stack, copy contents of "f" into "ftmp" and insert "ftmp" into the beginning of the fifo (i.e. perform "copy-on-insert"). The size of "ftmp" is also checked and set to target_size, if necessary. If wait is set to true, will wait until there are frames available in the stack.

void	clear ()
	Clear the cache.

void	dump ()
	Dump frames in the cache.

bool	isEmpty ()
	Cache empty or not.

int	seek (long int ms_streamtime_)
	Seek to a desider stream time. -1 = no frames at left, 1 = no frames at right, 0 = ok.

int	keySeek (long int ms_streamtime_)
	Seek to a desider stream time. -1 = no frames at left, 1 = no frames at right, 0 = ok. From the nearest key-frame to the target frame.

Frame *	pullNextFrame ()
	Get the next frame. Returns NULL if no frame was available.

bool	has_delta_frames
	Does the cache have streams with key-frame, delta-frame sequences.

Cache	cache
	The queue.

Cache::iterator	state
	The state of the queue.

std::mutex	mutex

std::condition_variable	condition
	The Event/Flag.

std::condition_variable	ready_condition
	The Event/Flag for FrameFifo::ready_mutex.

Detailed Description

FrameCache works like FrameFifo, but frames are not pre-reserved.

They are reserved / released on-the-spot
