I've been working on trying to make an addon for the videos on http://www.cbc.ca/video. Using wireshark to examine the traffic as I start a video, I get the following URL as part of a SMIL exchange:

rtmp://cp37429.edgefcs.net/ondemand/?auth=daFaVb4auamaCbba7bPcKbtd5d3d0aNdncu-bmPr9F-bl-slr_CqpYCkDoGBw&aifp=v0001&slist=netstorage<break>netstorage/Coronation_Street_Thursday-12_24_51-2010-09-24.flv

As a simple test, I put this in as a listItem in a simple addon, but XBMC skips it as unplayable. Does anyone have any clues? The escaped ampersands I thought I might have to "unescape", but I'm at a loss as to what to do with the escaped break tag. Eek

Any tips on where to look/what to try welcome. If you're really curious I can make available the actual Wireshark trace (just short of 1 MB).

First thing is to grab rtmpdump and use that to play around with things rather than trying to get it working in XBMC straight away - allows you to quickly try different parameters etc. until you get it doing something useful.

I'm sure others will have more useful things to say about how to ferrit out the "real" urls.

Cheers,
Jonathan

Sometimes those auth strings are time sensitive in my experience. So you have to make the connection before it expires or it will refuse the connection.

addition: also if you split the url at the '<break>' then take the first part as the rtmp url and then use the second as the playpath. I have seen it done this way before.

Thanks for the info, guys. rtmpdump is a big help. Now I'm getting an access denied (even with an updated URL I just pulled). A cursory google has brought up many a hit with people struggling with rtmp feeds. Looks like I've got some reading ahead of me... Huh

If you wouldn't mind posting the exact parameters you are trying and verbose rtmpdump output. I think I could spot the problem.

Much obliged. Here's the SMIL reply I pulled from the packets:

Here's the command I ran:

Code:
rtmpdump -z -o test.flv -r "rtmp://cp37429.edgefcs.net/ondemand/?auth=daFaUcGbHbVcCcUbfcUaxb3a6cecydub0dc-bmPOHP-bl-rmn_Fru0ClIpCCB&aifp=v0001&slist=netstorage" -y "netstorage/Coronation_Street_Friday-12_46_51-2010-09-24.flv"
