◆ cFrameDetector()

cFrameDetector::cFrameDetector	(	int	Pid = 0,
		int	Type = 0 )

Sets up a frame detector for the given Pid and stream Type.

If no Pid and Type is given, they need to be set by a separate call to SetPid().

◆ Analyze()

int cFrameDetector::Analyze	(	const uchar *	Data,
		int	Length,
		bool	ErrorCheck = true )

Analyzes the TS packets pointed to by Data.

Length is the number of bytes Data points to, and must be a multiple of TS_SIZE. Returns the number of bytes that have been analyzed. If the return value is 0, the data was not sufficient for analyzing and Analyze() needs to be called again with more actual data. Error checks can be turned off by setting ErrorCheck to false. This is used when regenerating the index file, where the first chunk of data is scanned for the PAT/PMT and then a rewind is done on the file.

Returns the aspect ratio, or arUnknown if this information is not available.

◆ Errors()

int cFrameDetector::Errors	(	bool *	PreviousErrors = NULL,
		bool *	MissingFrames = NULL )

Returns the total number of errors so far.

This includes TS errors and missing frames (each missing frame counts as one error). If PreviousErrors and MissingFrames are given, these will return the final information about these conditions.

◆ IndependentFrame()

bool cFrameDetector::IndependentFrame ( void )

inline

Returns true if a new frame was detected and this is an independent frame (i.e.

one that can be displayed by itself, without using data from any other frames).

◆ NewFrame() [1/2]

bool cFrameDetector::NewFrame	(	bool &	PreviousErrors,
		bool &	MissingFrames )

Returns true if the data given to the last call to Analyze() started a new frame.

PreviousErrors is set to true if there were any errors in the previous frame. MissingFrames is set to true if there were any missing frames before this one. The results returned in PreviousErrors and MissingFrames are only valid if the function returns true.
