After this commit timeshift and recording not working anymore.Black screen and time not running(still at 0:00).

DM8000 with oscam.

I revert the commit in my build-envorinment  and it's working again(tested a few times)..

Perhaps only DM8000 related. Can not test with other boxes.

The idea of this commit is to use a demux in asc order 0,1,2.. when there is descrambling involved.

Dreamboxes have less demuxes capable of descrambling. Can you post the results of command ls /dev/dvb/adapter0/ ?

Maybe there is another bug triggered from above commit in Dreamboxes.

Tomorrow this update will land to users so we'll see if others have problem too.

Demuxers 5 (demux0..4) and only 4 can descramble (ca0..3)

Can you run enigma2 manually (init 4 && enigma2) and see if there is error logged when you try to perform timeshift or recording?

[athoik]

Interesting, you run out of demuxers!

Are you using "Descramble receiving http streams" config? (Under settings)

If yes can you disable it?

[athoik]

Can you try also this one on file dvb.cpp

-if (fe)
+if (fe || (cap & iDVBChannel::capDecode))
			{
				++i;
			}

[Beeker]

-Descramble receiving http streams- was disabled already. But Yes or No..It makes no different. Both setting don't work for timeshift/record.

[athoik]

Try that: https://github.com/a...350a8948a7ca54b

I can't use

-			if (fe)

Because it's not in the latest code of dvb.cpp.

It is few lines below, use the patch from my previous post.

[Beeker]

Ok..i missed that. i try your patch now.

[Beeker]

Now timeshift and rec working with your patch.

[athoik]

Nice! Thanks for testing.

Edited by athoik, 9 November 2015 - 00:18.

[Beeker]

You're welcome.

[wheelwright]

my vu solo2 also has this issue since I updated today 9.11.15, will this problem be fixed if I update tomorrow?

[athoik]

Correct, tomorrow the fix will be in.

[wheelwright]

athoik, thanks for the reply.
Can I ask why previously recorded TV programs are affected (black screen) but download media plays OK..... are only certain media types affected with black screen play back issues?

[athoik]

You can check Demuxers (all/CA) in OpenPLi wiki to get an idea http://wiki.openpli.org/comparison

The boxes that have less CA demuxers had issues if you where trying to descramble http streams
(and http streams are handled like pvr/recording).

PS. It was a nasty bug, but code will become simpler soon
