netcv2dvbip

This is a tool for streaming DVB TS packets via udp multicasts on demand from the netceiver. It listens for IGMP(v1/v2/v3) join/leave multicast group messages on the network and starts/stops the corresponding streams accordingly. It uses a channels.conf file for channel information. Each channel is mapped to one multicast group starting with 239.255.0.1 and so on.

Quick Compile Howto (Linux):

1. Compile and install libnetceiver
   https://github.com/vdr-projects/libnetceiver

2. Checkout netcv2dvbip
   git clone https://github.com/vdr-projects/netcv2dvbip.git

3. cd netcv2dvbip
   make

4. ./netcv2dvbip

Notes:

• Each UDP packet contains 7*188=1316 bytes ( 7 TS packets)
• channels.conf: only frontend paramters are needed. PIDs are extracted from the PAT/PMT on demand.

Known Issues:

• Linux: netcv2dvbip make use of the multicast routing API to be able to receive all IGMP (v1,v2) messages on the subnet without joining all groups. If you have configured 200 channels, then at least those 200 groups would have to be joined to receive the group specific queries. IGMPv3 does not suffer this "problem", since all reports are sent to the group 224.0.0.22. So, if you are already using software that make use of this API, netcv2dvbip will fail to start, because only one program can make use of this API.

ChangeLog:

2009-??-?? version 1.0.0
           - initial release

2010-06-03 version 1.1.0
           - bugfixes:     * number of channels > 255 is now handled correctly
                           * PMT PIDs > 255 had a wrong entry in the PAT
           - new features: * DVB-C and DVB-T support
                           * support for VDR-1.7.x channels.conf format
                             (older formats and ReelVDR format are still supported)
                           * playlist file generation (M3U)
                           * EPG support: new command line option "-e" activates
                             sending of EIT packets (PID 0x12) in the stream.
2010-06-17 version 1.1.1   * bugfix: port number was not set correctly in M3U file
                           * bugfix: high CPU load (select() timeout was not
                                     set correctly)
                           * changed: streams now also use non-blocking sockets
                           * Windows only: activate built-in MLDv2 reporter only for
                                           Windows XP
