Presentation
mumudvb is a program that can redistribute streams from DVB on a network using multicasting. It is able to multicast a whole DVB transponder by assigning each channel to a different multicast IP.
History : mumudvb is originally a modification of dvbstream that cr@ns [1] made. We have decided to redistribute it.
Obtaining mumudvb
Mumudvb is intended to be packaged in debian. For the moment you must get the sources and compile them yourself.
You can get the sources Here
Features overview
- Stream channels from a transponder on different multicast IPs.
- The program can rewrite the PAT Pid in order to announce only present channels (useful for some set-top boxes)
- Beta support for scrambled channels
- Support for autoconfiguration : mumudvb is able to parse the ts stream to find information about the channels and stream them. So you need only the tuning parameters to stream a full transponder.
