Live playlist, must #EXT-X-TARGETDURATION and #EXTINF be equal?
<p>I have this m3u8 file. #EXT-X-TARGETDURATION is 8. the #EXTINF of first segment is 6. When the avplayer switched to this m3u8, it gave the following error.</p>

<blockquote>
  <p>Error Domain=CoreMediaErrorDomain Code=-12312 \"Media Entry time value
  does not match previous playlist for MEDIA-SEQUENCE 477000: 8.000000

<p>The question is
         in a live playlist, must #EXT-X-TARGETDURATION and #EXTINF of each segment be equal?! I can't find any document from Apple to define this rule. In this document, <a href="https://developer.apple.com/library/ios/technotes/tn2288/_index.html" rel="nofollow">https://developer.apple.com/library/ios/technotes/tn2288/_index.html</a><br>
    the Lie Playlist sample, they are all same.</p>
