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().

int cFrameDetector::Analyze | ( | const uchar * | Data, |
int | Length | ||
) |
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.

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).
