[vdr] Pb with softdevice and CAM (was: Pb with Viacess2 CAM onbudget card with vdr 1.3.17)

[Dominique Dumont <domi.dumont@free.fr>]

Hello

I've done some more tests and I think that softdevice triggers a
problem with CAMs (Red Viacess with Smart TV satellite budget card - a
twinhan DST clone)

Short story: It looks like softdevice prevents vdr from setting up CAM
when viewing encrypted channels

Long story is here ...

I may have the beginning of an explanation. I launched vdr without
softdevice plugin and the user log is quite different:

  Dec  4 17:10:34 localhost vdr[24330]: probing /dev/dvb/adapter0/frontend0
  Dec  4 17:10:34 localhost vdr[24333]: tuner on device 1 thread started (pid=24333, tid=16386)
  Dec  4 17:10:34 localhost vdr[24334]: Section handler thread started (pid=24334, tid=32771)

  Dec  4 17:10:34 localhost vdr[24330]: found 1 video device
  Dec  4 17:10:34 localhost vdr[24330]: ERROR: invalid primary device number: 2
  Dec  4 17:10:34 localhost vdr[24330]: ERROR: no primary device found - using first device!
  Dec  4 17:10:34 localhost vdr[24330]: setting primary device to 1

vdr is rightfully complaining about the wrong primary device
number. This problem was not detected using softdevice.

Once I changed setup.conf with "PrimaryDVB = 1", I get :

  Dec  4 17:19:16 localhost vdr[24597]: reading EPG data from /video/epg.data
  Dec  4 17:19:16 localhost vdr[24597]: probing /dev/dvb/adapter0/frontend0

  Dec  4 17:19:16 localhost vdr[24597]: ERROR: no OSD provider available - using dummy OSD!

This message is normal since I have a budget card and softdevice is not running.

  Dec  4 17:19:18 localhost vdr[24601]: changing caids of channel 546 from 0 to 500

From this message, I gather that the CAM is handled by vdr. Am I right ?

  Dec  4 17:19:18 localhost vdr[24601]: channel 6 (TF1) event 15:56 '7 À LA MAISON' status 4

At least some EPG informations are going through.


So now I run vdr with softdevice:

Now I'm confused, I though that "primary device" was related to DVB card ???

  Dec  4 17:38:33 localhost vdr[25187]: ERROR: no useful data seen within 10556952 byte of video stream

Now, we have a problem, there's no message related to "caids" and the
video stream is scambled.. Is softdevice getting in the way ??


next step: I'm going to try to record a scrambled channel without
softdevice. I'll let you now what I find. (But now I have to modify
again setup.conf)
