Hi guys,

 

I'm trying to write a different softcam manager plugin for PLi and I need the exact CAID of the current service while there is no ECM  / no softcam running. Is there any example for that? I checked PLi and open plugin sources but cannot find anything?

 

Anyone having an idea about that? I would really appreciate for any response !

See with our standard skin on the left top on the 2nd infobar.... Or menu -> info -> service

Thanks for the fast response ! But unfortunately, when I stop softcams and there is no ECM (and no ECM info file created by softcam), on encrypted channels I see "FTA:000:000 ....." . I attached the screen capture.

 

So what I'm trying to understand is it possible to find CAID without any ECM / softcam

Then you need to use the console (putty telnet) and dvbsnoop.... here the actial used ecms are displayed... but al least you can see the chid.

To find available crypto systems for a specific stream, you need to parse PMT. I've seen some skins that show available CAIDs of channel, so I guess it is somehow possible to get this PMT parsing from python too.

 

edit: OK, found it.

 

 
        service = self.source.service
        if service:
            info = (service and service.info())
            if info:
                caids = info.getInfoObject(iServiceInformation.sCAIDs)
......

I just tested below command but get no CAID related information with "dvbsnoop -s pidscan" command. I believe, since there is no ECM this tool also gives no result.

 

BTW, I need to find CAID in Phyton. Of cource I can use a system call but a phyton way would be much more effective, if possible.

 

 

But I'm still unsure that there is a way to find CAID without ECM. May be CAID is just a part of ECM concept and there is no CAID info on standart DVB data???

Thanks for the response mate !

 

But unfortunately I tested this code last night without any success. This code also depends on ECM and without ECM/working softcam it reports "0" as CAID.

Type in console: ./dvbsnoop -n 1 -nph 1 and enjoy....

Thanks!!! This really works. So now I really have a way to find caid with a system call from the Phyton. Below command parses the caid from the output of dvbsnoop:

 

dvbsnoop -n 1 -nph 1 | grep CA_system_ID | awk -F "(" '{print $2}' | awk -F ")" '{print $1}'

 

 

I still would like to know if there is a pure phyton way to do same ?

Look in the PliExtraInfo.py converter... see the loop at line 86.... (were the "letterbar" is made)...

 

It would be nice when something is added to the PID screen of the service info screen (menu->info->service)

@malakudi, sorry you are right . Your code is working. I'm confused.

 

@littlesat, I tested the code you and malakudi mentioned and this works like a charm. Here is how I used it. May be someone need it in the future:

 

			service = self.session.nav.getCurrentService()
			info = service and service.info()
			if service is None:
				return
			info = service and service.info()
			if not info:
				return
			caids = info.getInfoObject(iServiceInformation.sCAIDs)
			for caid_entry in caids:
				f = open('/tmp/caids_dump.txt', 'a')
				f.write(str(hex(caid_entry)) + "\n")
				f.close()

 

BTW, I aggree with you, I would like to see this on service info screen if PLi developers could change related code.

 

 

 

Case is solved. Thanks for both of your quick and usefull responses !

That would be very nic indeed!

buyukbang, please have a look at my request here:

http://openpli.org/f...mation-service/

Maybe you will manage to do something like that? Thanks.

What is the dvbsnoop? Is it a plugin?

 

How Can I get it for OE 2.0 Merlin3 image on my DM800SE ?

Where to run this code? 

 

Should I run it in telnet?

[littlesat]

This code dumpts the caids in a file...? Not on the OSD....

What file you mean? please explain a more. 

 

What about post  #13?

can current ecm and cw reply be found using dvbsnoop from running softcam
