About
-----
DVBStreamer is an console based application to stream an entire DVB service
over UDP.
It differs from other DVB streaming applications by the use of the DVB-SI to
work out the PIDs to stream and correctly stream services which use a separate
PCR PID.

Requirements
------------
DVBStreamer requires the following libraries:
sqlite3 (http://www.sqlite.org/)
readline 

(libdvbpsi is no longer need as this has been included in DVBStreamer since 0.7)

Installation
------------

Before building dvbstreamer you will need the latest version of the following packages:
sqlite3     3.3.x
readline

Now download and extract the latest source from the sourceforge download page

Once you've done that the next thing to do is run configure to setup the makefile, to do this enter the following at the command prompt (add any options you would normal add when building using configure)

./configure

When configure has finished and created all the make files its just a matter of running make to build the application

make

Once make has finished doing its thing the next step is installing dvbstreamer to you chosen location. You will probably want to do this step as root

make install

Setup
-----
Before you can actually start to use dvbstreamer you need to initialise it's database of service to do this you'll need a channels.conf file produces by the linuxtv.org utility scan. Go here if you need help with scan.

When you have a channels.conf file you then need to run setupdvbstreamer with the file you've just created.
To setup dvbstreamer to use a terrestrial tuner on adapter 0 use the following command:

setupdvbstreamer -t channels.conf

To setup dvbstreamer to use a satellite tuner on adapter 0 use the following command:

setupdvbstreamer -s channels.conf

To setup dvbstreamer to use a cable tuner on adapter 0 use the following command:

setupdvbstreamer -c channels.conf
        
If you are setting up an adapter other than 0 add the -a <adapter number> option to the commands above.

If you have 2 or more cards of the same type in your system you can link the first cards database to the second cards database by simply creating a hard link in the dvbstreamer directory in your home directory ~/.dvbstreamer

for example to use the same database for card 1 and 2 you would do the following

ln ~/.dvbstreamer/adapter1.db ~/.dvbstreamer/adapter2.db


Running
--------
  Starting DVBStreamer

  Using a Startup file

  MRLs

Starting DVBStreamer
--------------------
To start dvbstreamer you need to specify an IP address and a UDP port where the selected service will be streamed to. You can also optionally specify which adapter to use using the -a option.

For example to start dvbstreamer using adapter 2 and send the selected service to 192.168.1.1 and UDP port 1234 you would use the following command

dvbstreamer -a 2 -o udp://192.168.1.1:1234

To select a service to stream use the select command (see the Commands section for more information).

For example:

select BBC ONE

Will tune to the multiplex that contains BBC ONE and stream all the packets belonging to that service to 192.168.1.1:1234 over udp.

The stats command can be used to verify that packets are being processed and set to the selected output destination.

For information on other commands see the Commands section.

Start up files
--------------

Start up files can be useful for doing things that you always want to be setup before you get to the dvbstreamer prompt. For example you may always want the TDT and EIT tables redirected to a specific UDP port on your local computer.

To use a startup file simple add the -f option on the command line specifying the file to read.

For example to use the file eitredirect to redirect EIT tables to port 1235 on your local computer you would use the following:

dvbstreamer -o udp://localhost:1234 -f eitredirect

And in eitredirect you would have

# Redirect EIT tables to port 1235 on localhost
addmf eitoutput udp://localhost:1235
addmfpid eitoutput 0x12

Its as simple as that, you can use all the commands that you can use on the dvbstreamer prompt.

MRLs (Media Resource Locator)
-----------------------------

These are in the form <transport>://<details> and are used to specified how and where to send the output of a service filter or a manual output.

The following MRLs are currently supported (although this list can be extended by plugins):
Transport Usage           Description
-------------------------------------
udp       udp://host:port Packets are sent via UDP (7 TS packets per UDP packet) 
                          to the specified port on the host.
file      file://filepath Packets are written to the specified file.
null      null://         Packets are thrown away.

current.........Print out the service currently being streamed.
serviceinfo.....Display information about a service.
pids............List the PIDs for a specified service
stats...........Display the stats for the PAT,PMT and service PID filters
lssfs...........List all secondary service filters

quit
----
Usage:  quit

Exit the program, can be used in the startup file to stop further processing.

lsservices
----------
Usage:  lsservies [mux | <multiplex frequency>]

Lists all the services currently in the database if no multiplex is specified or if "mux" is specified only the services available of the current mux or if a frequency is specified only the services available on that multiplex.

lsmuxes
-------
Usage:  lsmuxes

List all multiplexes.

select
------
Usage:  select <service name>

Sets the specified service as the service to be streamed to the primary output, this may mean tuning to a different multiplex.

current

Back serviceinfo

Usage:  serviceinfo <service name>

Displays running status, conditional access status and whether EPG information is present for the specified service. Note only services in the current multiplex can be queried.

pids
----
Usage:  pids <service name>

List the PIDs for the specified service.

Plugins
-------
Plugins allow DVBStreamer to be extended beyond the simple filtering and
streaming of DVB services.

Plugins can:
- Add new delivery methods (check out fileoutput.c for a simple example of a
  delivery method plugin)
- Add new commands.
- Add new PID filters (for example to extract EPG data)
- Detect when the service/multiplex is changed.

The commands lsplugins and plugininfo can be used to inspected the loaded plugins.

Documentation for the interfaces into DVBStreamer can be generated using the
doxygen and the doxygen.config file in the base directory of dvbstreamer.
