[Request] support for npo.nl live videostreams

[Reino17]

My last request for now, because I'm asking a lot.
For complete npo.nl support, I was wondering if it's possible for youtube-dl to generate npo.nl live video-stream-urls, and only generate these urls, since live-streams can't be downloaded.
Npo.nl has the following live-streams:
http://www.npo.nl/live/npo-1
http://www.npo.nl/live/npo-2
http://www.npo.nl/live/npo-3
http://www.npo.nl/live/npo-nieuws
http://www.npo.nl/live/npo-politiek
http://www.npo.nl/live/npo-best
http://www.npo.nl/live/npo-doc
http://www.npo.nl/live/npo-101
http://www.npo.nl/live/npo-cultura
http://www.npo.nl/live/npo-zappxtra
http://www.npo.nl/live/npo-humor-tv

Youtube-dl at the moment:

Please visit this helpdeskweb.nl-website, because this guy has already done most of the work. The focus here is one the list of "Genereer link"-links, line 171-173 of the html-source:

<div id='channel-wrapper'>(geen URL's zichtbaar? Probeer CTRL+F5)<script type="text/javascript">
   $('#channel-wrapper').html(generateTable()); 
</script></div>

...and the corresponding javascript in http://www.helpdeskweb.nl/script.js:

function getStream(url,id){
  $("#"+id).html('Bezig...');

  $.getScript("http://ida.omroep.nl/npoplayer/i.js", function(){
    var url2 = "http://ida.omroep.nl/aapi/?type=jsonp&callback=?&stream=" + encodeURIComponent(url) + "&token=" + npoplayer.token;                              
    $.getJSON(url2, function(jsonx){   
      $.ajax({ dataType: 'jsonp',
        url:jsonx.stream,
        jsonp: "callback",
        success:function(json2){                           
          $("#"+id).html("<input type='text' readonly='readonly' value='"+json2+"' onclick=\"this.setSelectionRange(0, this.value.length)\"></input>");   
        }
      });                     
    }); 
  });
}

function generateTable(){
  var output = "<table border='0' style='width: 100%;'>";

  var channels    = {"Nederland 1":"http://livestreams.omroep.nl/live/npo/tvlive/ned1/ned1.isml/ned1.m3u8", 
                     "Nederland 2":"http://livestreams.omroep.nl/live/npo/tvlive/ned2/ned2.isml/ned2.m3u8",

  var keys = $.map( channels, function( value, key ) {
    var name = key.replace(/ /g, '-');
    output += "<tr><td class='channel'>"+key+"</td><td class='url' id='"+name+"'><a href='javascript:' onclick=\"getStream('"+value+"','"+name+"')\">Genereer link</a></td></tr>";
  });
  return output + '</table>';                      
}

For http://www.npo.nl/live/npo-1 (Nederland 1) for instance it generates the following temporary(!) manifest-url:
http://l2cmb7eb7ed22b0054b46076000000.fde6e2a445ca7074.kpnsmoote1e.npostreaming.nl/d/live/npo/tvlive/ned1/ned1.isml/ned1.m3u8.
...after which the live videostream-urls after a self._extract_m3u8_formats() will be:
http://l2cmb7eb7ed22b0054b46076000000.fde6e2a445ca7074.kpnsmoote1e.npostreaming.nl/d/live/npo/tvlive/ned1/ned1.isml/ned1-audio=64000-video=200000.m3u8
http://l2cmb7eb7ed22b0054b46076000000.fde6e2a445ca7074.kpnsmoote1e.npostreaming.nl/d/live/npo/tvlive/ned1/ned1.isml/ned1-audio=128000-video=500000.m3u8
http://l2cmb7eb7ed22b0054b46076000000.fde6e2a445ca7074.kpnsmoote1e.npostreaming.nl/d/live/npo/tvlive/ned1/ned1.isml/ned1-audio=128000-video=700000.m3u8
http://l2cmb7eb7ed22b0054b46076000000.fde6e2a445ca7074.kpnsmoote1e.npostreaming.nl/d/live/npo/tvlive/ned1/ned1.isml/ned1-audio=128000-video=900000.m3u8
http://l2cmb7eb7ed22b0054b46076000000.fde6e2a445ca7074.kpnsmoote1e.npostreaming.nl/d/live/npo/tvlive/ned1/ned1.isml/ned1-audio=128000.m3u8

Is this possible with youtube-dl? Could this code be translated to python?

npo live streams will be supported in the next version. Thanks for the report.

Absolutely fantastic! The urls work and with ffmpeg in place one can even 'record'.
Thanks a million for your hard work!
