<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;"><DIV>Hi all,</DIV>
<DIV> </DIV>
<DIV>I have a question about the ogg vorbis decoder. As far as I know, there are three vorbis headers -- ID, Comment and Codebook. And in ID header, I can get the sample rate, maximum bitrate, nominal bitrate and minimum bitrate. Now, I want to get the play time of the file, so I use the file length to divide the nominal bitrate, and get the play time, but it is always shorter than the real time. So I want to know how to get the precise play time of the ogg vorbis file?</DIV>
<DIV> </DIV>
<DIV>By the way, why many files don't set the maximum bitrate and minimum bitrate?</DIV>
<DIV> </DIV>
<DIV>Thank you very much. </DIV>
