Fancybox 2 and soundcloud media helper case - fancybox

Question

I was wondering if some could help me to produce another case in Fancybox 2 media helper for Soundcloud. I need it to load the soundclooud iframe when the fancybox is triggered - otherwise with a number of embeds things go really slow.
I'm not very familiar with regular expressions - hence my enquiry.
The google part looks like this:
google_maps : {
matcher : /maps\.google\.([a-z]{2,3}(\.[a-z]{2})?)\/(\?ll=|maps\?)(.*)/i,
type : 'iframe',
url : function( rez ) {
return '//maps.google.' + rez[1] + '/' + rez[3] + '' + rez[4] + '&output=' + (rez[4].indexOf('layer=c') > 0 ? 'svembed' : 'embed');
}
}
Now if we take the standard iframe code for soundcloud:
<iframe width="100%" height="166" scrolling="no" frameborder="no" src="https://w.soundcloud.com/player/?url=http%3A%2F%2Fapi.soundcloud.com%2Ftracks%2F91535490"></iframe>
I believe we would take the url from the iframe as the direct link does not contain the id of the track - only string representation of it.
What I've got so far (trying hard ;) - is the following, which doesn't work:
soundcloud : {
matcher : /w\.soundcloud\.([a-z]{2,3}(\.[a-z]{2})?)\/(\?ll=|url\?)(.*)/i,
type : 'iframe',
url : function( rez ) {
return '//w.soundcloud.com/player/?url=$1';
}
}
Could someone point me in the right direction here please?

Answer 1

Ok - for those who also wonder - I've managed to get it to work with the following:
soundcloud : {
matcher : /w\.soundcloud\.com\/player\/(.*)\/?(.*)/,
type : 'iframe',
url : function( rez, params, obj ) {
obj.width = '600px';
obj.height = '166px';
return '//w.soundcloud.com/player/' + rez[1];
}
}
