SYNOPSIS
tsdecrypt [options]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.OPTIONS
MAIN OPTIONS
- -i, --ident <ident>
- Set ident that will be used when logging to syslog. The preferred format for the ident is PROVIDER/CHANNEL.
- -d, --daemon <pidfile>
- When started become a daemon and write pid file to <pidfile>.
- -N, --notify-program <program>
-
Execute <program> when predefined events happen. In order for
this option to work --ident should also be used.
You can use notify-script.example file as notification program and an example on how to create your own notification script.
See EVENTS section for detailed description of the events.
- -S, --syslog
- Write log messages to local syslog.
- -l, --syslog-host <addr>
- Set syslog host. tsdecrypt sends messages to this host over tcp in syslog compatible format. syslog-ng was tested as receiving syslog server.
- -L, --syslog-port <port>
- Syslog server port. The default value is 514.
- -F, --log-file <filename>
- Write logging data to <filename>. This option can be used along with syslog.
- -D, --debug <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.
- -j, --pid-report
- When this option is used, tsdecrypt on exit reports how much packets were received on each PID.
- -b, --bench
- Bechmark the CSA decryption. The benchmark is single threaded. If you want to fully test your CPU, run couple of tsdecrypts in parallel.
- -V, --version
- Show program version.
- -h, --help
- Show program help.
INPUT OPTIONS
- -I, --input <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 stdin.
- -1, --input-source <ipaddr>
- Set multicast input source address using IP_ADD_SOURCE_MEMBERSHIP. This works only for IPv4 multicast. The default value is 0.0.0.0 (do not apply source filtering).
- -R, --input-rtp
- 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.
- -z, --input-ignore-disc
- Do not report input discontinuity or RTP discontinuity errors.
- -M, --input-service <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 --input-service is not used, tsdecrypt chooses the last service listed in PAT.
- -T, --input-buffer <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.
- -W, --input-dump <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
OUTPUT OPTIONS
- -O, --output <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 stdout.
- -o, --output-intf <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/).
- -t, --output-ttl
- Set multicast ttl. The default value is 1.
- -g, --output-tos
- Set TOS value of output packets. The default is not to set any specific TOS.
- -r, --output-rtp
- Enable RTP output. The default output is standard MPEG TS over UDP, this option enables tsdecrypt to output RTP packets.
- -k, --output-rtp-ssrc <ssrc>
- -u, --no-output-on-error
- Filter all output when there is no valid code word.
- -p, --no-output-filter
- 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.
- -y, --output-nit-pass
- Pass through NIT packets when output filtering is enabled.
- -w, --output-eit-pass
- Pass through EIT (EPG) packets when output filtering is enabled.
- -x, --output-tdt-pass
- Pass through TDT/TOT packets when output filtering is enabled.
CA OPTIONS
- -c, --ca-system <ca_sys>
-
Process input EMM/ECM from <ca_sys>. Currently tested and working CA systems
are CONAX, CRYPTOWORKS, IRDETO, VIACCESS, MEDIAGUARD
(SECA) and VIDEOGUARD (NDS), NAGRA, BULCRYPT,
GRIFFIN and DGCRYPT. Other supported CA system that you can choose but is not tested is DRECRYPT. The default <ca_sys> is CONAX. You can override the default CAS CAIDs by using --caid parameter. - -C, --caid <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 --ca-system parameter.
- -Y, --const-cw <code_word>
- Set constant code word to be used for decryption. The <code_word> should contain 32 hex chars. For example using a1a2a3a4a5a6a7a8b1b2b3b4b5b6b7b8 as parameter will set even code word to a1a2a3a4a5a6a7a8 and odd code word to b1b2b3b4b5b6b7b8.
- -Q, --biss-key <biss_key>
- Set BISS key to be used for decryption. The <biss_key> should contain 12 chars (hex). For example 112233445566 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).
CAMD OPTIONS
- -A, --camd-proto <protocol>
- Set CAMD server protocol. Valid protocols are CS378X and NEWCAMD. If this option is not used the default protocol is CS378X (camd35 over tcp).
- -s, --camd-server <hostname[:port]>
- Set CAMD server address. You can use IPv4/IPv6 address or hostname. If the port is not set then 2233 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 ([]) for example: [1234::5678]:2233
- -U, --camd-user <username>
- Set CAMD user name. The default is user.
- -P, --camd-pass <password>
- Set CAMD user password. The default is pass.
- -B, --camd-des-key <des_key>
- Set DES key used by NEWCAMD protocol. The default is 0102030405060708091011121314.
- -4, --ipv4
- Connect to CAMD server using only IPv4 addresses of the server. IPv6 addresses would be are ignorred.
- -6, --ipv6
- Connect to CAMD server using only IPv6 addresses of the server. IPv4 addresses would be are ignorred.
EMM OPTIONS
- -e, --emm
- Enable sending EMM's to CAMD for processing. By default EMM processing is disabled and only ECM are processed.
- -Z, --emm-pid <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.
- -E, --emm-only
- 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.
- -f, --emm-report-time <seconds>
- Set interval for EMM reports. The default is 60 seconds. Set to 0 to disable EMM reports.
- -a, --emm-filter <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 <filter_defintion> is Command/Settings where
the commands are: accept_all, reject_all, accept
and reject.
For more information about filtering and for example filters, please read FILTERING file that comes with tsdecrypt. This option can be used multiple times to define up to 16 different filters.
ECM OPTIONS
- -X, --ecm-pid <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.
- -v, --ecm-only
- 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.
- -H, --ecm-report-time <seconds>
- Set interval for ECM reports. The default is 60 seconds. Set to 0 to disable ECM reports.
- -G, --ecm-irdeto-type <int>
- Set the index of the IRDETO ECM stream. NOTE: This option is deprecated, better use --ecm-irdeto-chid.
- -2, --ecm-irdeto-chid <int>
- IRDETO CA sends ECMs mixed in single stream on single PID. In order to select the correct ECM stream the so called CHID number is used. Oscam reports what CHIDs are activated in your card and tsdecrypt allows you to set the correct CHID number using this option. tsderypt reports what CHIDs are available in the incoming ECM stream. The CHID is 16-bit number (0x0000 - 0xffff).
- -K, --ecm-no-log
- Disable logging of ECMs and code words. Code word errors and stats reports are not affected by this option.
- -J, --cw-warn-time <seconds>
- After how much seconds to warn if valid code word was not received. The default is 60 seconds. Set to 0 to disable the warning.
- -q, --ecm-and-emm-only
- 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.
DEBUG OPTIONS
- -n, --ecm-file <file.txt>
-
Read ECM from text file and send it to CAMD server for processing. This
option must be used along with --caid and --input-service
options.
The file should be normal text file, the format of the file is described bellow.
- -m, --emm-file <file.txt>
-
Read EMM from text file and send it to CAMD server for processing. This
option must be used along with --caid and --input-service
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:
# comment aa bb cc dd ee ff 01 02 03 04 # Other comment 0x05 0x06 0x07
EVENTS
Notification events are sent when --notify-program and --ident options are used. The event parameters are set as environmental variables before executing the external notification program. The variables are:
_TS Unix timestamp of the event.
_IDENT tsdecrypt ident parameter with "/" replaced by "-".
_MESSAGE_ID Event message id (for example START, STOP, etc...).
_MESSAGE_MSG Event message id with "_" replaced by " ".
_MESSAGE_TEXT Event message text. Human readable event message.
currently defined events are:
START tsdecrypt was started.
CODE_WORD_OK Valid code word was received and decryption is
working ok.
NO_CODE_WORD No valid code word was received for X seconds. The
decryption process have been suspended until valid
code word is received.
NO_EMM_RECEIVED No EMM packet have been received for X seconds.
INPUT_TIMEOUT There was no data on the input.
INPUT_OK The data have appeared on the input.
STOP tsdecrypt was stopped.
See notify-script.example for an example on how to create external notification program.
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.
