.SH NAME
tsdecrypt \- Decrypt mpeg transport stream.
.SH SYNOPSIS
.B tsdecrypt
[\fIoptions\fR]
.SH DESCRIPTION
tsdecrypt reads incoming mpeg transport stream over UDP/RTP or file and
then decrypts it by after retriving code words from OSCAM or similar
CAMD server. tsdecrypt communicates with CAM server using cs378x (camd35
over tcp) protocol or newcamd protocol.
.SH OPTIONS
.TP
.SH MAIN OPTIONS
.PP
.TP
\fB\-i\fR, \fB\-\-ident\fR <ident>
Set ident that will be used when logging to syslog. The preferred format
for the ident is PROVIDER/CHANNEL.
.TP
\fB\-d\fR, \fB\-\-daemon\fR <pidfile>
When started become a daemon and write pid file to <pidfile>.
.TP
\fB\-N\fR, \fB\-\-notify\-program\fR <program>
Execute \fB<program>\fR when predefined events happen. In order for
this option to work \fB\-\-ident\fR should also be used.

You can use \fBnotify\-script.example\fR file as notification program
and an example on how to create your own notification script.

See \fBEVENTS\fR section for detailed description of the events.
.TP
\fB\-S\fR, \fB\-\-syslog\fR
Write log messages to local syslog.
.TP
\fB\-l\fR, \fB\-\-syslog\-host\fR <addr>
Set syslog host. tsdecrypt sends messages to this host over tcp in
syslog compatible format. syslog\-ng was tested as receiving syslog server.
.TP
\fB\-L\fR, \fB\-\-syslog\-port\fR <port>
Syslog server port. The default value is \fB514\fR.
.TP
\fB\-F\fR, \fB\-\-log\-file\fR <filename>
Write logging data to <filename>. This option can be used along with syslog.
.TP
\fB\-D\fR, \fB\-\-debug\fR <level>
Set message debug level. Currently there are five message levels.
0 = default messages, 1 = show PSI tables, 2 = show EMMs 3 = show
duplicate ECMs, 4 = packet debug. 5 = packet debug + mpeg ts packet
dump.
Setting higher level enables the levels bellow.
.TP
\fB\-j\fR, \fB\-\-pid\-report\fR
When this option is used, tsdecrypt on exit reports how much packets
were received on each PID.
.TP
\fB\-b\fR, \fB\-\-bench\fR
Bechmark the CSA decryption. The benchmark is single threaded.
If you want to fully test your CPU, run couple of tsdecrypts in parallel.
.TP
\fB\-V\fR, \fB\-\-version\fR
Show program version.
.TP
\fB\-h\fR, \fB\-\-help\fR
Show program help.
.TP
.SH INPUT OPTIONS
.PP
.TP
\fB\-I\fR, \fB\-\-input\fR <source>
Where to read from. tsdecrypt supports input from file (\-I file://file.ts),
IPv4 multicast/unicast addresses (\-I 224.0.0.1:5000) or IPv6 multicast/unicast
addresses (\-I [ff01::1111]:5000). By default tsdecrypt reads from \fBstdin\fR.
.TP
\fB\-R\fR, \fB\-\-input\-rtp\fR
When reading from multicast assume the input is RTP stream. NOTE: No RTP
processing/reordering of packets is done. The 12 byte RTP header is just
stripped out and the stream is then processed as normal mpeg transport
stream over UDP multicast.
.TP
\fB\-z\fR, \fB\-\-input\-ignore\-disc\fR
Do not report input discontinuity or RTP discontinuity errors.
.TP
\fB\-M\fR, \fB\-\-input\-service\fR <service_id>
Choose the service id. This option must be used when the input is MPTS
in order to select the correct service (program). If the input is MPTS
and \fB\-\-input\-service\fR is not used, tsdecrypt chooses the last service
listed in PAT.
.TP
\fB\-T\fR, \fB\-\-input\-buffer\fR <miliseconds>
Use this option to delay the decoding for certain amount of milliseconds. This
allows tsdecrypt to decode services even if OSCAM returns code word too late.
For example SkyUK sends code words ~700 ms before it starts using them. This
means that if OSCAM is unable to return code word in less than 700 ms the
decryption will fail for a small amount of time. Setting \-\-input\-buffer 1000
will solve the problem in this case.
.TP
\fB\-W\fR, \fB\-\-input\-dump\fR <filename>
Save input stream in <filename>. If the input is RTP, the file will contain
the data without RTP headers (pure mpeg transport stream). Easiest way to
save the input is using command line like the following:

tsdecrypt \-I 239.78.78.78:5000 \-O /dev/null \-s 0.0.0.0 \-W file.ts
.TP
.SH OUTPUT OPTIONS
.PP
.TP
\fB\-O\fR, \fB\-\-output\fR <dest>
Output decrypted stream to <dest>. The destination can be IPv4 multicast
address (\-O 239.0.0.1:5000), IPv6 mulicast address (\-O [ff01::2222]:5000),
hostname that resolves to IPv4/IPv6 address (\-O example.com:5000) or file.
When the output is file, the file name should be prefixed with file://
(\-O file://out.ts)if it doesn't contain / symbol. The default output
is \fBstdout\fR.
.TP
\fB\-o\fR, \fB\-\-output\-intf\fR <value>
Set multicast output interface. The value can be IPv4 address of the output
interface  (default: 0.0.0.0 /any/) or in the case of IPv6 the interface
number (default: -1 /any/).
.TP
\fB\-t\fR, \fB\-\-output\-ttl\fR
Set multicast ttl. The default value is \fB1\fR.
.TP
\fB\-g\fR, \fB\-\-output\-tos\fR
Set TOS value of output packets. The default is not to set any specific TOS.
.TP
\fB\-r\fR, \fB\-\-output\-rtp\fR
Enable RTP output. The default output is standard MPEG TS over UDP, this
option enables tsdecrypt to output RTP packets.
.TP
\fB\-k\fR, \fB\-\-output\-rtp\-ssrc\fR <ssrc>
.TP
\fB\-u\fR, \fB\-\-no\-output\-on\-error\fR
Filter all output when there is no valid code word.
.TP
\fB\-p\fR, \fB\-\-no\-output\-filter\fR
Disable output filtering. By default the output filter is enabled and only
PAT/PMT/SDT and data packets are left in the output. Everything else not
mentioned in PMT like NIT, EIT, TDT tables and unknown pids is removed.
.TP
\fB\-y\fR, \fB\-\-output\-nit\-pass\fR
Pass through NIT packets when output filtering is enabled.
.TP
\fB\-w\fR, \fB\-\-output\-eit\-pass\fR
Pass through EIT (EPG) packets when output filtering is enabled.
.TP
\fB\-x\fR, \fB\-\-output\-tdt\-pass\fR
Pass through TDT/TOT packets when output filtering is enabled.
.TP
.SH CA OPTIONS
.PP
.TP
\fB\-c\fR, \fB\-\-ca\-system\fR <ca_sys>
Process input EMM/ECM from <ca_sys>. Currently tested and working CA systems
are \fBCONAX\fR, \fBCRYPTOWORKS\fR, \fBIRDETO\fR, \fBVIACCESS\fR, \fBMEDIAGUARD\fR
(\fBSECA\fR) and \fBVIDEOGUARD\fR (\fBNDS\fR), \fBNAGRA\fR and \fBBULCRYPT\fR.
Other supported CA system that you can choose but is not tested is \fBDRECRYPT\fR.
The default \fB<ca_sys>\fR is \fBCONAX\fR. You can override the default CAS CAIDs
by using \fB\-\-caid\fR parameter.
.TP
\fB\-C\fR, \fB\-\-caid\fR <caid>
Directly set CAID. This is useful if you have couple of CA streams from
one CA but with different CAIDs or CAS that is unsupported by \fB\-\-ca\-system\fR
parameter.
.TP
\fB\-Y\fR, \fB\-\-const\-cw\fR <code_word>
Set constant code word to be used for decryption. The \fB<code_word>\fR should
contain 32 hex chars. For example using \fBa1a2a3a4a5a6a7a8b1b2b3b4b5b6b7b8\fR
as parameter will set even code word to \fBa1a2a3a4a5a6a7a8\fR and odd code
word to \fBb1b2b3b4b5b6b7b8\fR.
.TP
\fB\-Q\fR, \fB\-\-biss\-key\fR <biss_key>
Set BISS key to be used for decryption. The \fB<biss_key>\fR should
contain 12 chars (hex). For example \fB112233445566\fR is valid BISS key.
If the BISS key contains 16 chars this means that the key CRC is embeded
in the key. These keys are also supported (they are the same as using
constant code word with same code words for even and odd keys).
.TP
.SH CAMD OPTIONS
.PP
.TP
\fB\-A\fR, \fB\-\-camd\-proto\fR <protocol>
Set CAMD server protocol. Valid protocols are \fBCS378X\fR and \fBNEWCAMD\fR.
If this option is not used the default protocol is \fBCS378X\fR (camd35 over
tcp).
.TP
\fB\-s\fR, \fB\-\-camd\-server\fR <hostname[:port]>
Set CAMD server address. You can use IPv4/IPv6 address or hostname. If the port
is not set then \fB2233\fR is used as default port. 2233 is the default port
for CS378X protocol but for NEWCAMD protocol you probably should choose other
port number. To set static IPv6 address you have to put in in brackets (\fB[]\fR)
for example: \fB[1234::5678]:2233\fR
.TP
\fB\-U\fR, \fB\-\-camd\-user\fR <username>
Set CAMD user name. The default is \fBuser\fR.
.TP
\fB\-P\fR, \fB\-\-camd\-pass\fR <password>
Set CAMD user password. The default is \fBpass\fR.
.TP
\fB\-B\fR, \fB\-\-camd\-des\-key\fR <des_key>
Set DES key used by NEWCAMD protocol. The default
is \fB0102030405060708091011121314\fR.
.TP
\fB\-4\fR, \fB\-\-ipv4\fR
Connect to CAMD server using only IPv4 addresses of the server. IPv6
addresses would be are ignorred.
.TP
\fB\-6\fR, \fB\-\-ipv6\fR
Connect to CAMD server using only IPv6 addresses of the server. IPv4
addresses would be are ignorred.
.TP
.SH EMM OPTIONS
.PP
.TP
\fB\-e\fR, \fB\-\-emm\fR
Enable sending EMM's to CAMD for processing. By default EMM processing
is \fBdisabled\fR and only ECM are processed.
.TP
\fB\-Z\fR, \fB\-\-emm\-pid\fR <pid>
Set EMM pid manually. This option is useful for services that have
couple of EMM streams from one CA system. Without this option tsdecrypt
always chooses the first stream from the chosen CA system.
.TP
\fB\-E\fR, \fB\-\-emm\-only\fR
Disable ECM processing and stream output. This option is useful if the EMM
stream has very high rate and is interfering with ECM processing. Using
\-\-emm\-only you can run special tsdecrypt dedicated only to keeping
card entitlements up to date.
.TP
\fB\-f\fR, \fB\-\-emm\-report\-time\fR <seconds>
Set interval for EMM reports. The default is \fB60\fR seconds. Set to \fB0\fR
to disable EMM reports.
.TP
\fB\-a\fR, \fB\-\-emm\-filter\fR <filter_definition>
Add EMM filter described by <filter_definition>. EMM filters are useful if
you want to limit the number of EMMs that should reach your CAMD server.
The basic \fB<filter_defintion>\fR is \fBCommand/Settings\fR where
the commands are: \fBaccept_all\fR, \fBreject_all\fR, \fBaccept\fR
and \fBreject\fR.

For more information about filtering and for example filters, please
read \fBFILTERING\fR file that comes with tsdecrypt. This option can be
used multiple times to define up to \fB16\fR different filters.
.TP
.SH ECM OPTIONS
.PP
.TP
\fB\-X\fR, \fB\-\-ecm\-pid\fR <pid>
Set ECM pid manually. This option is useful for services that have
couple of ECM streams from one CA system. Without this option tsdecrypt
always chooses the first stream from the chosen CA system. Run tsdecrypt
with \-\-debug 2 and look at CA descriptors in PMT to see what CA streams
are available.
.TP
\fB\-v\fR, \fB\-\-ecm\-only\fR
Process ECMs but do not decode the input stream. This option is useful if
you just want to populate you OSCAM DCW cache but do not want to waste CPU
time on stream decoding.
.TP
\fB\-H\fR, \fB\-\-ecm\-report\-time\fR <seconds>
Set interval for ECM reports. The default is \fB60\fR seconds. Set to \fB0\fR
to disable ECM reports.
.TP
\fB\-G\fR, \fB\-\-ecm\-irdeto\-type\fR <type>
Set ECM IRDETO type. IRDETO CA send ECMs with different id mixed
into one stream. Only one of the IDs are valid in given time. This
option lets you choose which stream to process. The default stream
type is \fB0\fR.
.TP
\fB\-K\fR, \fB\-\-ecm\-no\-log\fR
Disable logging of ECMs and code words. Code word errors and stats
reports are not affected by this option.
.TP
\fB\-J\fR, \fB\-\-cw\-warn\-time\fR <seconds>
After how much seconds to warn if valid code word was not received.
The default is \fB60\fR seconds. Set to \fB0\fR to disable the warning.
.TP
\fB\-q\fR, \fB\-\-ecm\-and-emm-only\fR
Process ECMs and EMMs but do not decode the input stream. This option combines
\-\-ecm\-only and \-\-emm\-only options. Use it if you want to populate your
OSCAM DCW cache and keep your card entitlements updated but do not want to
waste CPU time on stream decoding.
.TP
.SH DEBUG OPTIONS
.PP
.TP
\fB\-n\fR, \fB\-\-ecm\-file\fR <file.txt>
Read ECM from text file and send it to CAMD server for processing. This
option must be used along with \fB\-\-caid\fR and \fB\-\-input-service\fR
options.

The file should be normal text file, the format of the file is described
bellow.
.TP
\fB\-m\fR, \fB\-\-emm\-file\fR <file.txt>
Read EMM from text file and send it to CAMD server for processing. This
option must be used along with \fB\-\-caid\fR and \fB\-\-input-service\fR
options.

Bellow is an example text file, lines starting with # are ignored and
also 0x prefixes are ignored. Any other symbol in the file is processed
as hex number. An example file might look like this:

.nf
    # comment
    aa bb cc dd ee
    ff 01 02 03 04
    # Other comment
    0x05 0x06 0x07
.fi

.SH EVENTS
Notification events are sent when \fB\-\-notify\-program\fR and \fB\-\-ident\fR
options are used. The event parameters are set as environmental variables
before executing the external notification program. The variables are:

  \fB_TS\fR             Unix timestamp of the event.
  \fB_IDENT\fR          tsdecrypt ident parameter with "/" replaced by "\-".

currently defined events are:

  \fBSTART\fR           tsdecrypt was started.

  \fBCODE_WORD_OK\fR    Valid code word was received and decryption is
                  working ok.

  \fBNO_CODE_WORD\fR    No valid code word was received for X seconds. The
                  decryption process have been suspended until valid
                  code word is received.

  \fBNO_EMM_RECEIVED\fR    No EMM packet have been received for X seconds.

  \fBINPUT_TIMEOUT\fR   There was no data on the input.

  \fBINPUT_OK\fR        The data have appeared on the input.
