descrambling stops after a few seconds on certain channels #97

Closed vdrfan closed 9 years ago

vdrfan commented 9 years ago

Hello, i have the same issue like maxodoble on #94 https://github.com/manio/vdr-plugin-dvbapi/issues/94

disable the expiration check doesn't help. no change with CheckExpiredCW=true or false. deycryption stops after 25s on all channels on transponder orf 12692. sounds like MAX_KEY_WAIT, but when looking at the code it has nothing todo with MAX_KEY_WAIT.

sc has no problems, and dvbapi has no problem on other channels.

the problem exist randomly (i have a peridiodical rec. timer on that channel) 08.06.2015 NOT OK 09.06.2015-14.06.2015 OK 15.06.2015 NOT OK 16.06.2015-12.06.2015 OK 23.06.2015 NOT OK 24.06.2015-06.07.2015 OK 07.07.2015 NO OK but OK since 19:10

tried to find the bug in: cDvbapiFilter::Analyze, but...

maybe this will help: when recording channel it stops after 25s. when makeing second recording on same channel, the first recording will also continue recording for 25s.

any idea, vdrfan.

You sure you correctly used the expiration CW switch? Did you have a notification in the vdr log about it? Can you try the socket mode? This way we will eliminate the plugin filtering code.

hi, i tiried to send you email with logs (mail adress wrong?).

i have noticed CW in the log, and i have also forced to true and false direct in code. i cannot test at this time in socket mode - but will do next time the problem occurs. its strange but i think it will happen again from monday to tuesday.

I tried to fix it by myself – but i have only a couple of hours to test, because the problem disapears by itself. and also I am not fit in scrambled content…

i think it has do to with CW but CW dont gets updated - for any reason.

Can you explain what is cDvbapiFilter::Analyze exactly for? Maybe it should also get called when TS_SCRAMBLING_CONTROL is set and Decrypt is returning false or something… (maybe the provider is sending garbage on that time).

In: cDvbapiFilter::Analyze There could be a problem in the code segment: if (i == max) {} else {Maybe we have here also a part of this filter?}

In: cDvbapiFilter::Analyze else if (it->data && (cc == it->lastcc + 1)) { Shouldn’t we check here also for tablelen? }

thanks, vdrfan

Ok. We discussed the problems via e-mail. If you can not reproduce the problem anymore, can we close this issue?
