fixed little bug in Demuxer

[publicocean0]

I send the patched function (index coud be out of array)

  Demuxer.prototype.seek = function(timestamp) {
     var index, seekPoint;
     if (this.format && this.format.framesPerPacket > 0 && this.format.bytesPerPacket > 0) {
       seekPoint = {
         timestamp: timestamp,
         offset: this.format.bytesPerPacket * timestamp / this.format.framesPerPacket
       };
       return seekPoint;
     } else {
       index = this.searchTimestamp(timestamp);
//fixed bottom line
       if (index>=this.seekPoints.length) index=this.seekPoints.length-1;
       return this.seekPoints[index];
     }
   };

I think in this place we need more checks. Your version give some errors too.
At this time only my version can correct errors in this place:

    Demuxer.prototype.seek = function(timestamp) {
      var index, seekPoint;
      if (this.format && this.format.framesPerPacket > 0 && this.format.bytesPerPacket > 0) {
        seekPoint = {
          timestamp: timestamp,
          offset: this.format.bytesPerPacket * timestamp / this.format.framesPerPacket
        };
        return seekPoint;
      } else {
	  index = this.searchTimestamp(timestamp);
	  if (this.format)
	  {
	  do {if (index>0) {index=index-1;}} while ((((this.duration*(this.buffered/100))-(this.seekPoints[index].timestamp/this.format.sampleRate * 1000))<((this.buffered==100)?6000:10000)) && (index>0));
	  } else
	  {
	  if (index>99)
	  index=99;
	  }
      return this.seekPoints[index];
      }
    };
