Update of /cvsroot/datatype/mp3/fileformat/pub
In directory cvs-new:/tmp/cvs-serv741/pub

Modified Files:
	mp3ff.h 
Log Message:
Implements IHXMediaBytesToMediaDur interface which is used in 
progressive-download situation.  It translates bytes downloaded so
far into a duration (that is the minimum of all the streams' durs
at that point in the file).  Also can be called to get complete-
file's dur.  Currently, local file objects are the only ones that
access these methods.

TODO: Remove prog-down work-around code from CRnMp3Fmt::GetPacket
and from statDone and replace stat...etc. with
mediaBytesToMediaDur...::ConvertFileOffsetToDur call.  If m_ulFileSize
!= ulFileSize then call UpdateDuration().
