channelfireball.com: Need help with a stream using RTMPdump

vivisect · #1 06-15-2011, 10:45 AM

I feel like I have tried a lot of different strings, and nothing seems to work. Thanks for any help given.

I should also note that this does work in Replay Media Catcher, but it gives me the downgraded flv, not the original mp4.

Page I am trying to grab a video from:

Code:

http://www.channelfireball.com/articles/channel-lsv-3-nph-draft-1/

Used URL Snooper to get the following MP4 link:

Code:

rtmp://cp101675.edgefcs.net/ondemand/&amp;mp4:3/794267721001/794267721001_982107155001_Channel-LSV---3-NPH-Draft--1---Drafting.mp4?__nn__=932629354001&amp;slist=3/794267721001/&amp;auth=daEb4aDdgbtdUd8bCa8deaUc2d

I get the following video players:

Code:

http://admin.brightcove.com/viewer/us1.25.05.00.2011-06-14161714/federatedVideoUI/BrightcovePlayer.swf

Code:

http://admin.brightcove.com/viewer/us1.25.05.00.2011-06-14161714/BrightcoveBootloader.swf?playerID=981350681001&playerKey=AQ%7E%7E%2CAAAAuO4LnSk%7E%2CAwdRtAYlwc5M-nuQqeTXyww-Ni08gz6R&purl=http%3A%2F%2Fwww.channelfireball.com%2Funcategorized%2Fchannel-lsv-3-nph-draft-1-alternate%2F&autoStart=&bgcolor=%23FFFFFF&debuggerID=&dynamicStreaming=true&flashID=myExperience&height=410&isUI=true&isVid=true&width=588

Code:

http://static.inplay.tubemogul.com/core/core-as3-v4.4.8.swf

Code:

http://static.inplay.tubemogul.com/core/core-as3-v4.4.8.swf?playerID=P-RS5-841&bootloaderID=B-0Y9-YVC

I've tried using all of these things, but I think my string is just wrong.

The most recent one I tried was:

Code:

rtmpdump -z -s "http://admin.brightcove.com/viewer/us1.25.05.00.2011-06-14161714/federatedVideoUI/BrightcovePlayer.swf" -r "rtmp://cp101675.edgefcs.net/ondemand/&amp;mp4:3/794267721001/794267721001_982107155001_Channel-LSV---3-NPH-Draft--1---Drafting.mp4" -o "part1.mp4"

Which gave me the following debug:

Use RTMPexplorer (changed bat file). Is it?

That's great! Totally works. But how about this. The stream that it grabs still seems to be the downgraded version. I admittedly don't know how these protocols work, nor how the player chooses the sample rate. Any ideas? The player seems to go to the high sample rate after about 30 seconds of play. I can't seem to get any other urls out of it though.

Replay Media Catcher and RTMPexplorer find and download exactly the stream that you start to play. Don't really know how to get a higher bitrate stream here. May be Wireshark can help.

you need a high bitrate?

How did you get those two different bitrates?
