[rtmpdump] Parsing an RTMPE URL

[Anony Mous]

Hello,

So I've been experimenting with using librtmp (the latest version from svn) integrated into XBMC. 
For the most part things work well, but I've been having a problem trying to connect to a video URL 
from a flash based TV website in Canada named CTV (only accessible from Canada I believe).  I should 
point out that I'm only having these problems because of the different URL format of the RTMPE 
streams.  RTMP streams work fine, it is only the encrypted streams that fail, and as I said, I think 
it is because of the URL format, not an encryption issue.  The complete URL looks like this (notice, 
I'm breaking it up across multiple lines to avoid 80 char line limits):

rtmpe://cp45924.edgefcs.net/ondemand/s_!ctv/shows/2010/03/31/ALLMYCH-10344-EP.CLIP01.mp4
?auth=dbEbzdDd4bLcKdgdwcAdKczdsdPaAdTd5dk-blWaqa-eS-iYG-txN4tmKCt
&aifp=v001
&slist=/s_!ctv/shows/2010/03/31/


So I take this URL and programatically change it to this before it is passed to librtmp:

rtmpe://cp45924.edgefcs.net/ondemand/s_!ctv/shows/2010/03/31/ALLMYCH-10344-EP.CLIP01.mp4
  swfUrl=http://watch.ctv.ca/Flash/player.swf
  swfVfy=true
  auth=dbEbzdDd4bLcKdgdwcAdKczdsdPaAdTd5dk-blWaqa-eS-iYG-txN4tmKCt
  authflag=true
  app=ondemand
  tcUrl=/s_!ctv/shows/2010/03/31/

So this results in a connect packet like this being sent out:

Unfortunately the response from the server is a connection reject message that looks like this:

Now, I don't think the way this video service is unique in the way it uses auth, aifp, and slist 
params, I'm just hoping someone knows how to transform this URL format into a connect packet that 
will succeed.  Any advice?
