How can I record an RTMP stream in real time?

Question

How can I record an RTMP stream (Adobe Flash video and audio) which is currently playing, as-is?

I have a very long video which can't be downloaded by any downloader I tested. So I want to scroll it to the desired position, playback and record only a small part.

If you're finding it difficult to use rtmpsrv.exe and rtmpsuck.exe from the command line, I recommend NirSoft's RTMPDumpHelper:

RTMPDumpHelper is a small utility that can help you to easily download RTMP video/audio streams. By combining this utility and the proxy server of RTMPDump toolkit, you can simply open a Web page containing RTMP video stream in your favorite Web browser, and while watching the video, it'll be saved to your disk automatically as .flv or .mp4 file.

I've successfully used it to record complete RTMP streams, but never tried a partial download so far. If the underlying rtmpsrv.exe/rtmpsuck.exe proxies support it though then what you want to do should be possible.

Solution 2

You can try to use Web Stream Recorder tool, it works for me for most RTMP broadcasts, but not for all.

Have you tried rtmpsuck (not offensive word)?

I don't understand how to use it. Suppose I set RTMP server name in hosts to localhost. Now what? How rtmpsuck will know where to forward a connection? Also in my case Flash applet accesses RTMP server by it's IP address.

Do you have the full URI of the stream?

I see no any reaction in my case. When I open a video in browser (Chrome) nothing happens. May be it writes a file somewhere but does not say me about it. This is not Youtube video btw, this is some custom content.

Can you try with Firefox or even IE instead?

Ok, the applet is not compatible with FF, while it runs with IE and RTMPDumpHelper als runs, but stops recording once I scroll time slider. I can't record entire stream since it is very long.
