Issue Description
With DVBAPI, the CW is now decoded twice for the same channel
When the issue occurs
When a chan has 2 PROV ID that work, both are used indefinitely.
How the issue is reproducable
Try to decrypt RTS Un for instance
2015/09/13 14:57:37 2D7442C9 c (ecm) client (0500@023800/08E2/4333/2A:DD37D6607A): found ( 2 ms) by reader-1 (P/1/5/5) - RTS Un HD ()
2015/09/13 14:57:38 2D7442C9 c (ecm) client (0500@050800/08E2/4333/2A:FB0585CAAE): found ( 340 ms) by reader-2 (P/1/2/2) - RTS Un HD ()

Important extra info: it only happens if we start decoding as there is already a chan being decoded using dvbapi.
If it's using Demuxer 0, so it's the first decoding, it does not use 2 PIDS.
If it's started first, even if a second decoding is done (using Demuxer 1 then), it works, no dual decoding...

Decoding 2 providers!
0500:023800
0500:050800
Perhaps you should take this 1st to the forum and discuss the issue there http://www.streamboard.tv/

Not certain: as far as OSCam is concerned it's a request for 2 different channels as the channel is asked for 2 different providers. or different cards for the same provider.
CAID:PROVID
0500:050800 SRF V5
0500:023800 SRF V2.6
You can have multiple providers on one channel if you get request for that channel for for provider A and then for provider B that is 2.
Most likely you have a wrongly configured client.
Don't use this tracking system for discussions, discuss in forum: http://www.streamboard.tv/

Sorry but it is not a discussion !
This is clearly a bug, dvbapi should choose one of the 2 providers, not decode both obviously ...
This is a regression most probably due to recent commits

You should organise your settings and limit OSCam to one of the Provid and not offer both.
There are several possibilities for doing so.

Come on, this is not the problem!
I really don't get why just ignore what I am saying ?
1- it worked before, it is due to new changes
2 -Unless you select the dvbapi option to try all CAIDs at the same time, which is not my case, it should not decode 2 ecms pids for the same channel request. And even if you set this option, it will try first all CAIDs and then use only one.
So please take some minutes to reconsider what I am saying instead of blindly sticking to your "check your conf" solution.

You seem to be a very important person, not willing to use http://www.streamboard.tv/.
Your unknown box is requesting this channel. As you indicate. And for some reason it does so by using the other Provid
You only provide partial (very minimal) information.
Do as you please. I leave the fun to the developers.

But the board is for dicussion, I am clearly reporting a bug with logs and descriptions...
I use the board when I need to discuss something, this is not the case here!
If you are not a developer, why are you commenting here ? Just leave the developers do it.
It really looks like you have no clue what you are talking about ...
"Your unknown box is requesting this channel. As you indicate. And for some reason it does so by using the other Provid"
=> it just proves that you did not understand a word from what I said... so yes, please leave it to other people.
