Detailed Description

This class reads through the file specified and tries to find an mpeg frame. It then reads data from the header of the first frame encountered.

Version History
1.8 - 2002.10/20 by Tech
Fixed some bugs when detecting the first MPEG frame
1.7.1 - 2002.10/17 by gruni
Made Sourcecode compliant to the Sun CodingConventions
1.7 - 2002/02/25 by helliker
-Implemented a much better mpeg identification algorithm. -Added method for computing number of frames.
1.6 - 2002/02/03 by helliker
-New algorithm for determining presence of 1st frame. -More checks to ensure stability.
1.5 - 2002/01/22 by helliker
-Made stupid mistake that causes an infininte recursive loop when reading non-VBR files.
1.4 - 2002/01/21 by helliker
-Added support for VBR files. -Added fields for padding and private bits. -Added getFrameLength method.
1.3 - 2001/11/10 by helliker
-Fixed file handle leaks. -Added accessor to find the offset of the MPEG data.
1.2 - 2001/10/19 by helliker
All set for release.
