RTMPdump is a command line application. you can't run it by double clicking. easiest way for you will be to create a batch file and then run it.
Code:
1. Open up Notepad in Windows.
2. Go to File > Save As...
3. Choose your rtmpdump folder as the location to save.
4. Click on the dropdown box "Save as type:" and select "All files" instead of Text (*.txt).
5. Add .bat to the end of your file name before you save. For example, you would type Commands.bat.
6. Click on Save. If you did this correctly, you should see your file name in the title bar of Windows Notepad. Make sure that it reads as Commands.bat not Commands.bat.txt.
now put your command eg:
Code:
rtmpdump -r "rtmpe://cp40493.edgefcs.net:1935/ondemand?ovpfv=2.1.4" -a "ondemand?ovpfv=2.1.4" -f "WIN 10,2,159,1" -W "http://media.mtvnservices.com/player/prime/mediaplayerprime.1.7.0.swf" -p "http://www.southparkstudios.com/full-episodes/s15e01-humancentipad" -y "mp4:mtvnorigin/gsp.comedystor/com/sp/season-15/1501/acts/sp_1501_act1_1280x720_1200.mp4" -o sp_1501_act1_1280x720_1200.flv
into the batch file, then save and run this batch file to start downloading.
