Services pinning to specific CAM or do-not-descramble option

[Delitants]

I think this feature was requested earlier, but I can't find a related ticket. This is essential, please make possible pinning services to a specific CAM and do-not-descramble option per service (similar to existing flag -E but I want to set manually what service to pass though).

Situation is next. Tuner TBS 6590 with dual CI slot, TP has 3 services, one SHOULD be descrambled by CAM-1, second with CAM-2 and not otherwise, and third must be passed AS IS without even trying to process it, because it will be descrambled by softcam in different software.

Note: flag -E does not work in this scenario, because it still tries to send channel to an already busy CAM, it passes through only if cam refuses to descramble, but this is not the case.

Pinning services to a specific CAM is supported, but "ignoring" a service is not.

How do you pin them without physically using secondary tuner of the card?

[Jalle19]

I'm not sure how the TBS 6590 works, it could be that the CAM assignment cannot be controlled if the card doesn't work as "standalone" CI cards, like the Digital Devices models.

[catalinii]

CAM assignment works at the moment just for standalone CI cards (tbs 6900)

No way. In the tbs6590 CI are physically connected to the tuner and accordingly if you wish to use second CI you must use a second tuner.

Okay, I'm more interested in skipping services for descrambling in external software, second part of this ticket.

[Yuri666]

Theoretically it can be done - just do not send CA_PMT when switching to this channel. I don't know how difficult it is to implement. It's easier to use a dvb card without CI for these purposes.

[Jalle19]

I think "service skipping" could be reasonably implemented for standalone cards (using the same ddci.conf file), but for "bonded" CI slots it's a bit clumsy like Yuri explained.

[Yuri666]

for standalone cards it's already implemented in ddci.conf

[Delitants]

Why is it clumsy? -E switch does pass undecrypted service through when CAM refuses to decode it due to lack of entitlements. Coming from that, it should be possibly to just send raw stream without bothering CAM. Basically I just want to tap the same transponder and save on physical tuners.

In this hardware CAM1 is connected to Adapter1 on the device. In your example, if the TP is tuned on adapter 1, CAM-1 can be set to decrypt only service 1. Service cannot be descrambled with CAM2 because the stream from adapter 1 does not pass thru CAM2. If you use -c X:1 third stream wont attempt to use CAM1 X here is the number of the first adapter from the board (0 if no other cards are present)

I've tried that already, -c 1:1 -E, it does not pass through, it gets stuck in loop attempting to use CAM but throwing an error that no free PID slots available.

Can u upload logs?

Here you go. When I've started a second encrypted stream, which needs to be passed through, it loops with these messages and receiver does not get a stream.

This just means that the second encrypted stream will not be using CA2 (because one is already used). So at that point using -E should allow the stream to pass to the client

Well, it should but it does not send anything but some ~80 kbps on the output.

Do you have rights to decrypt the second channel with the CAM?

Can you add -l pmt and upload the (entire) log for the same repro?

Here, I switched the channels around by tuning them in opposite order. minisatip2.log

-O -x 8082 -y 555 -D 2 -e 2 -c 2:1 -j 2:15-1470 -M :5.0-5.0 -t -E -l ca,http,pmt -Z :0 -F /var/log/minisatip2.log

Output of a skipped channel is 21Kb, only data and no content:

If you use -c X:1 third stream wont attempt to use CAM1 X here is the number of the first adapter from the board (0 if no other cards are present)

For me, it just side effect. If third stream starts first it will be decoded by CAM. I suggest add ca.conf Then to read ca.conf and add to dvbca_process_pmt() if (sid==(sid from ca.conf)) return TABLES_RESULT_ERROR_NORETRY; So, this SID will not be decoded by any CAM. By other side one more conf file...

Some sort of config with list of services to be passed untouched would be great. But I can’t code that myself.

my bad, can you use "-v pmt" instrd of "-l pmt". I am looking for this message: https://github.com/catalinii/minisatip/blob/master/src/pmt.c#L1158

Enabled first channel - it went decoding fine, then enabled second channel to get passed through (which does not). minisatip2.log

[Jalle19]

@Delitants assuming the SID you want to omit from all your CAMs is 7000, can you add this to your ddci.conf and test https://github.com/Jalle19/minisatip/commit/6a525e13941e22048d278c630854d00ebb93c7cf ?

7000: # not assigned anywhere

You should see something like find_ddci_for_pmt: no suitable DDCI found for PMT 4 (sid 7000): not mapped to any DDCI device in ddci.conf in your log when you try to play that service.

Note that this only works for standalone CI adapters right now, not e.g. Enigma.

It's a bonded CI slot, TBS 6590. None of those ddci.conf manipulations give desired effect of simply skipping one channel passing it through.

[Jalle19]

Right, my PR will not help your situation then.

This line just allows passing encrypted packets from the original ddci adapter to the original one (in case oscam wants to decrypt them).

[Jalle19]

Closing this, is now implemented for standalone CI adapters
