libdvbtee is a stream parser and service information aggregator library for MPEG2 transport streams. The library includes a program service information (PSI) parser and support for various network streaming methods and is aware of the linux-dvb kernel API as well as HDHomeRun network streaming APIs.
The library contains enough functionality to power a full featured television middleware application, including the ability to acquire and stream data through UDP, TCP, HTTP, DMA and various other mechanisms.
libdvbtee_server allows for these features to be controlled from an http
session or command line interface, and can be used to control multiple tuners.
The dvbtee executable application provides a variety of features, including: scanning, tuning, EPG browsing, receive incoming network streams, stream out network streams, manage multiple tuners, and more...
The server can be accessed either by telnet or http. The default port number
is 64080, but this is configurable. The server_example uses port number 62080.
When accessing the server via http, precede commands by / and arguments by =. When accessing the server via telnet, enter in the form 'command=argument' and press enter.

comma (,) separated list of channels to scan /
scan maximum channel

To tune to service id 1 of physical channel 33 and stream it to a udp port:
./dvbtee -c33 -I1 -oudp://192.168.1.100:1234
To tune the second frontend of adapter 1 and stream the full TS of physical channel 44 to a tcp listener:
./dvbtee -c44 -otcp://192.168.1.200:5555
To listen to a TCP port and stream to a UDP port:
./dvbtee -itcp://5555 -oudp://192.168.1.100:1234
To parse a captured file and filter out the PSIP data, saving the PAT/PMT and PES streams to a file:
./dvbtee -Finput.ts -O3 -ofile://output.ts
To parse a UDP stream for ten seconds:
./dvbtee -iudp://127.0.0.1:1234 -t10
To scan for ClearQAM services using 5 tuners optimized for speed and partial redundancy:
./dvbtee -A2 -T5 -s4
To scan for ATSC services using 2 HdHomeRun tuners optimized for speed and redundancy:
./dvbtee -A1 -H -T2 -s3
To start a server using adapter 0:
./dvbtee -a0 -S
To start a server using tuner1 of a specific HdHomeRun device (ex: ABCDABCD):
./dvbtee -H ABCDABCD-1 -S
tuner specify tuner id
feeder specify feeder id
scan scan for services, optional arg comma (,) separated list of channels to scan
scanepg same as 'scan' with EPG data collection enabled during scan
startscan same as 'scan' but asynchronous
startscanepg combo of 'scanepg' and 'startscan'
tune tune to a channel or service, ie:
tune=33 (full mux) / tune=44~3 (svc id 3)
channels list channels
channel tune physical channel (unsafe - use tune instead)
service select service (unsafe - use tune instead)
stream add output file / tcp / udp / http stream, ie:
stream=udp:192.168.1.100:1234
stream=tcp:192.168.1.200:5555
stream=file:output.ts
stream (over http with no arg will begin streaming to current socket)
epg dump collected EPG data
xmltv dump collected EPG data in XMLTV format
stop stop the tuner
stopoutput stop the tuner and output
check display debug info if debug is enabled
debug enable debug
parser enable / disable the parser for data shovel
listen listen for TS on a TCP or UDP port
save save scanned channels
quit stop the server and exit
