Tvheadend

I got the same problem since I updated my ~1089 build to the newer ones (running 1133 now).

Unencrypted channels work fine, but encrypted channels simply stop/freeze.

I am not using CAPMT but newcamd (Code Word) protocol to Oscam

In the log I see:

An old copy of TvHeadend on my Synology works perfectly fine with the same Oscam-server.

In the Revisions-log on TvHeadend I notice Jaroslav Kysela made quite some changes to the descrambler/cwc-interface. Perhaps this is causing the issues we have..

Oscam produces when I switch to a channel which I do have a subscription too (and have valid entitlement):

I pulled build 1070 from the Repository and my problem is not in that build. Perhaps this will work for you too, Anthony.

To do this, you need to build it yourselves. What I did:
I looked up a suitable build from :
https://tvheadend.org/projects/tvheadend/repository/revisions?page=4
where I saw a date where it was still working (before Jaroslav Kysela his fixes to the ECM / Descrambler code -> I picked 39b6bc1d

git clone https://github.com/tvheadend/tvheadend
cd tvheadend/
git checkout 39b6bc1d
./Autobuild.sh (I'm running Ubuntu 14.04 - so that worked from this version on)

In your parent-directory you will now find a file called tvheadend_3.9.1070~g39b6bc1_amd64.deb
You can install this package by running

dpkg -i tvheadend_3.9.1070~g39b6bc1_amd64.deb

This will downgrade your current version to version 1070 (from 2014-07-10). This version works for me with encrypted channels fine.

Hope it works out for you as a temporary work-around.

Thanks for finding a commit point that solved your issues.

Going to give it a try here too.

Not done a huge amount of testing but the problem looks to have disappeared by reverting back to that commit.

Same problem here, after upgrading tvheadend encrypted channels stopped working after a couple of seconds, with an access denied message. Rolling back to commit 39b6bc1d worked for me.

aptitude install git build-essential debhelper libavahi-client-dev libssl-dev zlib1g-dev libcurl4-gnutls-dev liburiparser-dev
cd /usr/local/src/
git clone https://github.com/tvheadend/tvheadend
cd tvheadend/
git checkout 39b6bc1d 
./Autobuild.sh
cd ..
dpkg -i tvheadend_3.9.1070~g39b6bc1_amd64.deb

Hope it will be fixed in a future release

Same here with Ziggo. Hopefully fixed soon.

So far it looks like my issue has gone with g99ed831.

I haven't tested any earlier, just built from source earlier today.

Scratch that. Still issues

Confirmed to be not fixed;

2014-08-26 22:33:09.731 cwc: Can not descramble service "NPO 3 HD", access denied (seqno: 20 Req delay: 368 ms) from cwc-127.0.0.1-15050

2014-08-26 22:33:43.212 subscription: No transponder available for subscription "192.168.1.107 [ huisman | XBMC Media Center ]" to channel "NPO 3 HD"

Looking like issues are resolved for me.

It certainly looks that way.

Not fixed for me

2014-09-13 15:51:37.764 cwc: Can not descramble service "NPO 3 HD", access denied (seqno: 642 Req delay: 372 ms) from cwc-127.0.0.1-15050

Note that this problem should be fixed in v3.9-1529-gb2d0156 . If you have any problems, open a ticket (issue) and point to the trace log (descrambler,cwc).

Not fixed for me, so I opened a ticket as you suggested. https://tvheadend.org/issues/2311

Thanks for helping out!

OK, small bug was there and also ECM filtering was improved now. Try: v3.9-1537-g3ac7a43

More minor tweaks: v3.9-1539-g286509b

Jaroslav,

For me the build 3.9.1540~g962f99c is working properly. Thanks for the hard work, hopefully others can report it being fixed too

Fixed in the latest release

Thanks for the effort and all the good work.
