MediaWare Solutions MPEG SDK

An extension to MpegHeaderInfo.

It includes all the information contained in MpegHeaderInfo, and has the additional information that needs to be obtained by more time consuming analysis of the stream.

An MpegInfo object can be obtained from the MpegDecoder object by calling the getMpegInfo() function.

Construct and set the fields.

public MpegInfo ( const MpegHeaderInfo & x ) ;

public void setTotalTime ( float total_time ) ;

Set the total duration time in seconds.

public float getTotalTime ( ) const ;

Get the total duration time in seconds.

public void setStartFrame ( int start_frame ) ;
