Client URL Generation

Hi, new member here.

I'm writing a generic ABR client.  I already do HLS and DASH and want to add SMOOTH.  I'm using thehttp://playready.directtaps.net/smoothstreaming/ for a server.  I'm having trouble understanding the ABNF for how to generate the URL to request a fragment.  From the Manifest.

Url="QualityLevels({bitrate})/Fragments(video={start time})">
    <QualityLevel
      Index="0"
      Bitrate="2962000"
      FourCC="WVC1"
      MaxWidth="1280"
      MaxHeight="720"
      CodecPrivateData="250000010FD37E27F1678A27F859F180490825A645A6440000010E5A67F840" />

I asume that the URL would start with http://playready.directtaps.net/smoothstreaming/TTLSS720VC1/ then

QualityLevels"....

Everything I try from here, gives me parsing/syntax errors.  I'm just using 'wget' to perform experiments on the command line.

Can someone show me the actual completed url that I would use?  I just need one example of a completed URL and I'm off

Thanks in advance,

Mike
