High-Performance Streaming

DVBlast is written to be the core of a custom IRD, CID, or ASI gateway, based on a PC with a Linux-supported card. It is very lightweight and stable, designed for 24/7 operation.

DVBlast does not do any kind of processing on the elementary streams, such as transcoding, or remultiplexing. If you were looking for these features, switch to VLC. It does not stream from plain files (have a look at multicat instead).

DVBlast compiles and run on Linux and Mac OS X (with limited feature set).

Inputs - Outputs

DVBlast supports several input methods:
  • linux-dvb-supported cards (DVB-S, DVB-S2, DVB-C, DVB-T...) with or without CI interface
  • DVB-ASI cards (from Computer Modules or Deltacast)
  • UDP or RTP, unicast or multicast, streams carrying a transport stream

It outputs one or several RTP streams carrying transport streams with:
  • hardware or software PID filtering
  • PID-based or service-based demultiplexing
  • optional descrambling via CAM device
  • optional DVB tables
  • optional PID and SID remapping


User support and development is handled in the dvblast-devel mailing-list.


Hackers can participate to the development using git. The code is accessible from and you can browse the source online.
