I was able to capture streams from northpointministries.org using
Replay Media Catcher in the RTMP recording mode.
And I was able to use
rtmpdump as a plug-in for
Replay Media Catcher 4.1.1
Code:
Protocol: RTMP
URL match: streaming.northpointministries.org
Executable: rtmpdump.exe
Parameters: -r "{url}" -o "{file}" --app "{app}" --flashVer "{flashVer}" --swfUrl "{swfUrl}" --tcUrl "{tcUrl}" --pageUrl "{pageUrl}" --playpath "{playPath}"
But it is interesting that the web-site was breaking RMC connection as soon as I was closing the web-page or hitting the Stop button. I was able to solve it by right-clicking on the recording and selecting "Reprocess...".
