Problem getting CityTv streams to download with rtmpdump


 
When I download the videos with the following command, the videos won't play in ffmpeg or any player I've tried:

Code:
rtmpdump -r "rtmpe://cp80642.edgefcs.net/ondemand/?ovpfv=2.1.4" -y "mp4:citytv/1632712407/1632712407_1206922320001_citytv-fringe-s4-e03-copy.mp4" -W "hXXp://admin.brightcove.com/viewer/us20110929.2031/connection/ExternalConnection_2.swf" -o ep3.mp4
Here is the error I get when trying to use an XBMC plugin to stream the content:

Code:

Here's what mplayer/vlc/ffmpeg reports:

Any help would be very much appreciated.

Re: Problem getting CityTv streams to play or download


 
I've managed to verify that it is indeed a bad RTMPdump and not a bug in ffmpeg by using windows media player and flashplayer in windows. Does anyone know how the stream could be encrypted or something?

Re: Problem getting CityTv streams to play or download


 
I'm assuming it's some sort of encryption and these details need to be used to make the stream usable.. but I don't know how with the --conn or -C option.

Re: Problem getting CityTv streams to play or download


 
Here's the output of the command.. Why do I get the client sent 6, server answered 9 issue if I have RTMPdump version 2.4?

Code:
$ rtmpdump -r "rtmpe://cp80642.edgefcs.net/ondemand/?ovpfv=2.1.4" -y "mp4:citytv/1632712407/1632712407_1206922320001_citytv-fringe-s4-e03-copy.mp4" -W "hXXp://admin.brightcove.com/viewer/us20110929.2031/connection/ExternalConnection_2.swf" -o test.mp4

They are using FlashAccess DRM to protect their videos. AFAIK currently there is no method available to strip the DRM except screen capturing.
