RTSPdump is a tool for downloading a multimedia stream from a Windows Media server (WMServer). It accepts rtsp:// and mms:// URLs. It supports both UDP and TCP traffic. The stream can be saved into a WMV file for archiving or timeshifting purposes or passed through stdout to another program for processing or immediate viewing. It has also limited support for other brands of servers that also provide RTSP streaming.
