I have seen a implementation of the function <b><span style='font-weight:bold'>MPEG1or2ProgramStreamFileDuration()
</span></b>in the MPEG1or2FileServerDemux.cpp file which calculates the Program
Stream File Duration which refers to <b><span style='font-weight:bold'>getMPEG1or2TimeCode()
</span></b>and<b><span style='font-weight:bold'> computeSCRTimeCode() </span></b>function
. Could you please elaborate how <b><span style='font-weight:bold'>getMPEG1or2TimeCode
</span></b>and <b><span style='font-weight:bold'>computeSCRTimeCode()</span></b>
works.<o:p></o:p></span></font></p>
