Descrambling with Multiple CAMs

Post by mpajer »

Hello,
I just first compiled minisatip, I am totally new here so please forgive me if I am asking like a dumb..
So my situation:
Digital Devices Max M4 - 4x Multi-Band Tuner TV Card
Digital Devices Octopus Twin CI
TVHeadend on Ubuntu 20.04

I have two same CAMs for paid DVB-T(2)
Descrambling 2 channels simultaneously is working good even on different muxes with minisatip.
But when I try to play 3 or more channels, only 2 are working.
When I was using TVHeadend directly, it was able to descramble multiple channels per CAM.
So I think minisatip is using only first CAM, how to setup this so then it will use both CAMs?
Thanks

If they are independent CAM (that does not need to be attached to a tuners), minisatip has support for Multi transponder decryption (multiple channels from different transponders on the 1 CAM).
The tranditional way is also supported (CAM + tuner from one transponder).

If you want I can take a look at your logs:
./minisatip -f -l http

Try playing 3 channels, tell me the time when a channel stops decrypting.

Sorry to hijack this thread, but I have 3 TBS 6590 with 5 Cams, I can run 2 channels on ONE of the CAM (I guess the one I start 2 channels first on) the other CAMs is 1 channel per CAM, I tried run one minisatip server for each card also with -c 0:1 and -c 1:1 and so on. Is this the same problem as OP have ?

Probably no... the non independent CAM should have less issues now because each channel can be assigned to just one CAM.

Hi,
so after while, I have problem that my CAMs will stop working with minisatip after a while. I had this problem too with descrambling directly with tvheadend.
After some time, I need to insert my CAMs directly to the TV and they will start working again and I can use them with minisatip.
Has anyone similar problem?
I am attaching log from command

Code: Select all

./minisatip -l ca
The problem is here:

Code: Select all

[24/03 09:47:20.429 CA4]: MMI menu from CAM in the slot 0:
[24/03 09:47:20.429 CA4]:   title:    Pristup Irdeto
[24/03 09:47:20.429 CA4]:   subtitle: PROMPT
[24/03 09:47:20.429 CA4]:   item 1:   E033-0 V sucasnej dobe nie je mozne 
[24/03 09:47:20.429 CA4]:   item 2:   sledovat tento kanal.Ak problem 
[24/03 09:47:20.429 CA4]:   item 3:   pretrvava, obratte savas operator.
[24/03 09:47:20.429 CA4]:   item 4:   Vase zakaznicke cislo je:xxxxxxxxxx
[24/03 09:47:20.429 CA4]:   bottom:   Stlacte tlacidlo 'OK' alebo 'EXIT' pre ukoncenie.
This says that I am unable to watch channel, message shows also when I insert my CAM direclty to the TV but after few minutes it will start working.

Yes, I have exactly the same problem.
There seems to be a problem with writing EMMs since the last major code change for CAMs (I'm using DDCI).
