[Feature request] Icam support

[localhosthack0r]

Hi,
I just saw patched versions of tvheadend and libdvbcsa supporting Icam decryption.
Would it be possible to implement this for minisatip as well?

This is the patch for libdvbcsa from https://github.com/glenvt18/libdvbcsa

So I think from minisatip perspective it is just required to use the patched libdvbcsa and to call the dvbcsa_bs_key_set() function from csa.c with a additional parameter for the Icam decryption. They just throw in a '4' for this parameter from tvheadend.
In tvheadend it seems to be derived from something when selecting the right descrambler, if it is Icam:

                 }
               }
             }
+            dr->dr_ecm = (ptr[2] - ptr[4]) == 4 ? ptr[0x15] : 0;
             tvhtrace(LS_DESCRAMBLER, "ECM message %02x:%02x (section %d, len %d, pid %d) for service \"%s\"",
                      ptr[0], ptr[1], des->number, len, mt->mt_pid, t->s_dvb_svcname);
           }

But there I have no clue what the equivalent in minisatip would be. Help would be very appreciated! :)
Thank you!

[Jalle19]

What is this for? Any context?

[localhosthack0r]

Some providers with NDS Videoguard decryption are using this Icam. Seems to be a non-standard descrambling algorithm.
Sky Italia and Sky UK are using this since years, Sky Germany introduced it this summer.
And this patch is working according to some SAT forums at least for Sky Germany, for the others I don't know,...

[Yuri666]

Tvheadend can decrypt icam with "stream relay" oscam feature. Minisatip can't use this feature by definition.

[localhosthack0r]

Here is something about the ECM structure:
https://trac.streamboard.tv/oscam/ticket/4389

@Yuri666
Yes, right, the first implementations were using stream relay, but with the modified libdvbcsa it seems to work without stream relay!

[Yuri666]

I seen last patch to oscam. There only stream relay. Maybe I'm wrong, but not seen any other for now.

[localhosthack0r]

Patches are from here:
https://www.linuxsat-support.com/thread/153679-oscam-icam-tvheadend/?pageNo=1

[Yuri666]

There is patches for tvheadend and for libdvbcsa. Also needs patch for oscam.

[catalinii]

Does not seem complex but without access to a system that has this is very hard to implement.

[localhosthack0r]

Hi,
for testing purposes I now setup a LXC container where I tried out the tvheadend solution, with one tuner from minisatip as DVB input source.
It is working just with the two patches from above, no need to patch oscam, no need for streamrelay!

@catalinii
I can maybe setup another container with a test minisatip instance, which runs as client to my productive minisatip server and provide you ssh access to that.

Or, maybe also an option: I might be able to implement it myself, if you guide me to where I can access the ECM data to find out if it is Icam or normal CSA. Then I would provide a PR.

[localhosthack0r]

So,...
I did another experiment. As a quick & dirty hack, I just hardcoded the calls to the modified libdvbcsa with the '4' for Icam:

Not nice, as both client and server always try to decrypt, but as a quick workaround usable,...

Do you know if the channels using lcam working on a CI+ cam using minisatip?

no sorry, I don't know.

i tried this change - i have the modified libdvbcsa in place as soon as i change the csa.c and re-compile my normal channel (like orf) are not working anymore - i use kodi to watch through tvh and minisatip as my tuners having the oscam dvbapi.
i can see that my oscam server is sending the key but no picture in minisatip - once i change the line back in csa.c - orf channels are working again (key + picture) any idea?

thanks
holli

[localhosthack0r]

Hi holli,
yes, this behavior is expected. The missing part in minisatip is to distinguish between normal CSA and Icam.

My dirty workaround, making both decryption types working is to run two instances of minisatip, both connected to OSCam via dvbapi, where one (unchanged, productive setup) uses the normal libdvbcsa and the other instance working as SAT>IP client (-s) to the productive setup is using the modified minisatip and patched libdvbcsa, for the Icam channels. Please note that in the client the dvbapi connection to OScam is using an offset (-o 192.168.178.75:2000 ,10).

In your setup with tvh, I would recommend to use tvh for the decryption (not minisatip), with the patch from the first post, then both normal CSA and Icam is working, because there Icam- detection is already implemnted.

[localhosthack0r]

Hi all,
I have meanwhile implemented a version, where I try to identify Sky Germany / Austria channels via its CAIDs. This is working for me, so that this channels but also channels of other providers not using Icam are getting decrypted.

If you are interested, here is my playground:
https://github.com/localhosthack0r/minisatip

[catalinii]

@localhosthack0r can u provode remote access?

[dni1337]

The caid approach is not the best, because not all channels on sly de are icam encrypted.

so, why not check the ecm like they do it in oscam?

if(er->ecm[5] == 0xB0 && er->ecm[6] == 0x01 )

[Jalle19]

Is there official documentation about this ECM format somewhere?

[dni1337]

I guess its not... not public

Can someone test this with a patched dvbcsa?

i tried following:
got the patched libdvbcsa in place - make clean / git pull / make LIBDVBCSA=yes

i can watch now orf (this was not working before with the patched lib) but my other channel still will not show - from oscam it looks ok

so i get the key's but screen is still black - i use -o ip:port,10 as mentioned in the post's above but even without 10 it makes not difference.

thanks

Can you provide minisatip log?

[holli73]

@catalinii
sure - any special trace i should enable?

Hi @catalinii
thanks a lot for implementing the Icam support.
I did a quick test and for me it is working! I tested both, Icam channels and normal CSA. Both is working.

So I cannot confirm @holli73 findings. @holli73 which version of the libdvbcsa patch do you use? I have seen that there are more then one version, meanwhile,.. I have still the initial patch from the first post in this thread running.

[holli73]

@localhosthack0r
i did use the files from the first post - but i did still use the normal tvh and not the modified maybe this was the issue?
is there somewhere a quick guide what needs to be done that minisatip uses dvbapi and tvh as client can watch both types of channels.

thanks
holli

[catalinii]

All clients using minisatip should work...please upload the log

[holli73]

@catalinii

i did 2 tests -

1. direct dvbapi connect to oscam with icam on (vuzero4k) and tvh as client
   minisatip.dbg.txt

2. direct dvbapi connect to main oscam and this oscam is connect to icam oscam through cs378x
   minisatip2.dbg.txt

on both tries i had vlc running against the same channel through the vuzero4k and it worked fine

thanks
holli

[catalinii]

None of the logs show the latest minisatip version running.

Try to do git pull && make clean

[holli73]

@catalinii
sorry - i have a script to make this automated but no error handling in it ... i did modify the csa in the past and that was the reason the script did not pull because of stashed file...

i did a hard/reset/force and clean/build - now it is on the latest commit but still not working in my env. i just traced a try with setup 2 - from oscam log on vuzero it looks ok and the same on my main oscam:

here is the new minisatip capture:

Everything seems ok except validating the Control Word, because the stream obtained is not a valid stream.

Try maybe to clean the dvbcsa build and apply the patch again, then build and install

I am not sure if this is the issue as what you did is correct, but I have uploaded binaries with patched libdvbcsa here: https://github.com/catalinii/minisatip/releases

can you give them a try ?

@catalinii ,

thanks for the static build - but i can't run it - as my satip server is still on ubuntu 20.04 and glibc is only available till 2.31

holli@satip:~/BUILD/minisatip/minisatip.xx$ ./minisatip
./minisatip: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by ./minisatip)
./minisatip: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./minisatip)
holli@satip:~/BUILD/minisatip/minisatip.xx$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=20.04
DISTRIB_CODENAME=focal
DISTRIB_DESCRIPTION="Ubuntu 20.04.5 LTS"
holli@satip:~/BUILD/minisatip/minisatip.xx$

best regards
holli

@catalinii - i use now a native icam on x64 and minisatip works fine - even my compiled minisatip with modified libdvbcsa - thanks for your help and time.
