RTMP Download Helper

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.
RTMP is a streaming protocol used by Hulu, justin.tv, and by many live streaming Web sites.

How it works

  • When you run RTMPDumpHelper utility, it automatically detects your Web browser and attaches to it a small dll file - RTMPDumpHelper.dll
  • When the attached dll of RTMPDumpHelper detects that RTMP connection (TCP Port 1935) is initiated by your Web browser, it automatically redirects the connection to your own computer (connection to
  • The proxy of RTMPDump toolkit (rtmpsuck.exe) receives the redirected connection and downloads the RTMP stream to your hard drive. It also sends the downloaded RTMP stream back to your Web browser, so you can continue watching the RTMP video stream while it's downloaded by RTMPDump toolkit.
  • Be aware that effect of RTMPDumpHelper is only temporary. Once you exit from RTMPDumpHelper, the dll will be detached from your Web browser, and you'll be able to use your Web browser normally (Without the RTMP redirection).
