tsdecrypt
=========
tsdecrypt reads incoming mpeg transport stream over UDP/RTP and then
decrypts it using libdvbcsa and keys obtained from OSCAM or similar cam
server. tsdecrypt communicates with CAM server using cs378x (camd35 over
tcp) protocol or newcamd protocol.
License
=======
tsdecrypt is released under GNU GPL v2.
Installation
============
tsdecrypt depends on two external libraries - openssl and libdvbcsa.
You probably already have openssl installed, libdvbcsa can be downloaded
from http://www.videolan.org/developers/libdvbcsa.html

Development
===========
The development is done using git. tsdecrypt repository is hosted
at http://github.com/gfto/tsdecrypt
To clone the repository issue the following commands:
git clone git://github.com/gfto/tsdecrypt.git
git submodule init
git submodule update
make
The code is developed and tested under modern Linux. It is also
compiled from time to time under OS X but is not tested there.
Updating the code
=================
To update cloned tsdecrypt, go to the directory where the repository
is cloned and run the following commands:
git fetch origin
git merge origin/master
git submodule update
make distclean all
Examples
========
To get a quick start here are some example command lines. The default
CA system is set to CONAX, you can change it using --ca-system parameter,
see man page or program help for more options.
Examples:
# Decrypt multicast stream from 239.0.50.11:5000 using 10.0.1.1:2233
# as camd server and output decrypted result to 239.78.78.78:5000
tsdecrypt --camd-server 10.0.1.1 \
--input 239.0.50.11:5000 --output 239.78.78.78:5000
# Same as above but enable EMM processing
tsdecrypt --emm --camd-server 10.0.1.1:2233 \
--input 239.0.50.11:5000 --output 239.78.78.78:5000
# Same as above but do not filter output stream thus allowing
# EIT/TOT/NIT, etc tables to passthrough
tsdecrypt --output-filter --emm -camd-server 10.0.1.1 \
--input 239.0.50.11:5000 --output 239.78.78.78:5000
# Read stream over RTP and process VIACCESS encoded channel
tsdecrypt --ca-system VIACCESS --emm --camd-server 10.0.1.1:2233 \
--input-rtp --input 239.0.50.11:5000 --output 239.78.78.78:5000
OSCAM configuration
===================
In order for tsdecrypt to communicate with OSCAM, OSCAM must have user
added in oscam.user file and cs378x protocol must be enabled.
Example oscam.user file:
[account]
user = user
pwd = pass
group = 1
au = 1
uniq = 0
monlevel = 4
Example part of oscam.conf file:
[cs378x]
port = 2233
