My transcoding solution for the Raspberry Pi uses gstreamer-1.0 modules including the gstreamer-omx module which can access the GPU and use it for decoding and encoding of video streams. Note: in all following examples I run mumudvb on the same Raspberry Pi (localhost), using unicast and port 9082.

If you are running mumudvb on another device, it may still be useful to add a Raspberry Pi to your network just for transcoding as it runs on low power (12.5 VA maximum). But transcoding is limited to one channel at a time. It just needs the right kind of software.Ī Raspberry Pi 3 (or the older model 2) is powerful enough to run mumudvb, oscam and the transcoding software at the same time, serving (and descrambling) a whole transponder. The Raspberry Pi family of cheap ARM computer boards, priced from 5 (RPi Zero) to 35 USD (RPi 3), contains a GPU which is well suited for real time transcoding of DVB streams. More bandwitdh reduction can be achieved by reducing the number of audio channels and by also transcoding audio to a lower bandwidth. This is done by decoding the original dvb video stream, optionally reducing the image size and encoding it again, using a more efficient encoder (compared to MPEG 2, for example) or using a lower quality setting. The main use of transcoding is to provide a low bandwidth stream which can be served to a large number of clients or across a low bandwidth connection (your internet connection, for example).

The latest RPi package package also contains MuMuDVB and a tutorial and some scripts to create a MuMuDVB backend and a simple frontend. Please have a look at my online manual for details: Transcoding ManualĪn overview and download instruction can be found in the RPi forum There is a new transcoder package for the Raspbery Pi, rtranscode 4.0, which does work on both Raspbian Jessie and Stretch.
