The software package rtmpdump is a toolkit for RTMP streams. All forms of RTMP are supported with rtmp://, rtmpt://, rtmpe://, rtmpte://, and rtmps:// included.
The package includes three utilities, rtmpdump, rtmpsrv and rtmpsuck. Rtmpdump is used to connect to RTMP servers just like normal Flash video player clients, and capture the stream from the network, and save it to a file.
Rtmpsuck (rtmp.exe of ESFSoft Rtmp Downloader pops up after click “RtmpSrv” button) can be used to capture/grab streams which will lead the video can not be played online on built-in browser, and then it invokes transparent rtmpdump.exe command-line program after capturing useful URL for separately downloading rtmp:// multimedia stream from the Internet.
