[SOLVED] descramble fails at random times

Renato Riolino

Hi,

I have a TBS6982 dual tuner with both tunners connected to the same network using a unicable lnb. For descrambling I use newcamd.

I was previous running MythTV with this setup, except for descrambling (I was using ffdecsawrapper to create a dvb loop device with the descrambled data). Since I couldn't get ffdecsawrapper to work with tvheadend (I was getting kernel panics when trying to do a scan) I started to use the tvheadend descramble service (cwc).

But every couple of minutes I got some frame skips, on every channel. On TVH logs I got the following:

Jul 16 13:36:15 rbrserver tvheadend[27517]: cwc: Can not descramble service "HBO Family", access denied (seqno: 314 Req delay: 24 ms) from cwc-cstudonet.zapto.org-14500-1802

Jul 16 13:37:01 rbrserver tvheadend[27517]: TS: StarOne C2/11880H/HBO Family: MPEG2AUDIO

#4552 Continuity counter error (total 1)

I was using TVH stable release (on Ubuntu Trusty 64bits), but I have fetched the latest version from git (HTS Tvheadend 4.1-360~g0916e52) and the problem is still there.

Please let me know any more info that I need to provide.

Thanks

Renato

cilin dro

My recommendation is use TVH 3.9 untill comes out TVH 4.2 .All versions 4.0.x have many issues

Renato Riolino

Luis,

I have switched back to 3.9 and indeed no more accesses denied with descrambler.

I'm using tvheadend_3.9.1738~g20f603e now, but I was wondering if there is a more recent 3.9 release? At least on this release, TVH did not assigned a channel number for all the channels scanned. Maybe a more recent 3.9 ?? But I'm not a git guy and I don't know how to look for it.

Wich one are you using?

Thanks

Put OSCam before TVH and see more detailed log

Renato Riolino

Sorry, but I don't know what you mean by putting OSCam before TVH. Debug subsystem?

Install OSCam set curent newcam line,
from oscam set newcamd server and user and connect tvheadend on it.

Renato Riolino

Sorry for the long delay. I have never installed / configured oscam before.

I got it working now.

newcamd -> my oscam -> dvbapi -> tvheadend

No more descramble problems now.

Thank you!!
