int cIndexFile::GetClosestIFrame

(

int

Index

)

Returns the index of the I-frame that is closest to the given Index (or Index itself, if it already points to an I-frame).

Index may be any value, even outside the current range of frame indexes. If there is no actual index data available, 0 is returned.

int cIndexFile::GetLength ( const char *  FileName, bool  IsPesRecording = false  )

Calculates the recording length (number of frames) without actually reading the index file.

Returns -1 in case of error.
