24 DVBlast is a simple and powerful streaming application based on the
25 linux-dvb API. It opens a DVB device, tunes it, places PID filters,
26 configures a CAM module, and demultiplexes the packets to several RTP
27 outputs.
28 DVBlast is designed to be the core of a custom IRD or CID, based on a
30 PC with Linux-supported DVB cards.
31 DVBlast does not do any kind of processing on the elementary streams,
33 such as transcoding or remultiplexing. it does not stream from plain
34 files, only DVB devices. If you were looking for these features, switch
35 to VLC.
36
38 -a, --adapter <adapter>
39 Address of the adapter
40 -A, --asi-adapter
42 Read packets from an ASI adapter (0-n). If support for Deltacast
43 ASI cards is compiled in, prefix the adapter number with "delta‐
44 cast:" to select a Deltacast input. Deltacast inputs are num‐
45 bered as (100 * card number) + channel number.
