ETI conversion software

Additional libraries are needed:

• libfec - for Reed-Solomon FEC, may be enabled/disabled.
• libshout - for NI-to-HTTP converter (used modified one that supports aac and raw streaming).

ts2na - is MPEG-TS to ETI-NA converter. To use this tool, you have to provide pid to use, and optional offset size.

usage: ./ts2na [-p pid] [-s offset] [-i <inputfile>] [-o <outputfile>]

The output stream will be raw pid content. If negative offset is setted, then "pid" field will be used as part of the ETI stream.

na2ni - is ETI-NA to ETI-NI converter. This tool automatically detects E1-sync bits in bitstream and inversion flag. Also it extracts ETI-LI content of the stream and incapsulate it into ETI-NI frames. It is possible to disable Reed-Solomon error correction, then conversion speed will be dramatically increased.

usage: ./na2ni [--no-fec] [-i <inputfile>] [-o <outputfile>]

The output stream will be 6144-bytes aligned raw ETI-NI stream.

ni2http - is ETI-NI to http converter. This tool converts eti-stream to mp2 and relay it to icecast2 server.

usage: ./ni2http [--list] [--delay] [-i <inputfile>] [-c <config_file>]

Use "--list" option to find SID's and station names of the streams inside ETI. The "--delay" option have to be used when you are doing offline-relaying (from the file, not from the stream). So in that case application will wait 24ms after each eti frame, to make pseudo-realtime streaming.

The application also parses FIC for auto-detecting of station name and X-PAD of DAB and DAB+ for setting current song titles.

Config sample:

[server]
host:       localhost
port:       8000
user:       source
password:   hackme

[channel]
mount:      r5_live
sid:        0xc228

[channel]
name:       Custom channel name2
mount:      r1
sid:        0xc221

[channel]
#stream name will be auto-detected
#name:       Custom channel name3
mount:      r6music
sid:        0xc22b
# extract_pad - use DLS info as icecast metadata, enabled by default
extract_pad: 1
#extract_dabplus - converts DAB+ stream into AAC-ADTS,
#which playable by the internet-radio players, enabled by default
#If this option disabled, this stream can be directly passed to ODR-DabMod
extract_dabplus: 1

In [server] section the parameters of icecast server must be setted. In [channel] sections at least service-id of the channel and mount-point on the icecast server must be provided. To get list of service-id's, use "eti_ni2http --list -i "
