Bug #5293
Multiple one mux instances (Common Interface Service limit)
0%
Description
Hi all,
I have 2 tuners with a CI module. The CI module can only descramble 3 channels at the same time (of the same mux). I have set the service limit in "Configuration - CAs - Parameters - Common Interface Settings - Service Limit" to the value of 3.
When I start 3 recordings on the same mux, everything works fine but when I start the 4th recording, tvheadend doesn't start recording on the secondary tuner.

If set value to "2" is it work correct?
Hi,
Strange thing: If I set it to 2, I can only record 2 services at the same time (on same mux).
So, why doesnt it work if I set it to 3?

I'm sorry, I should clarify more.
If I set the limit to 2, I can ofcourse record 2 channels at the same time. The 3rd fails.
But tvheadend doesn't switch to the secondary tuner because it thinks all channels of 1 mux should be recorded on a single tuner.
I think the problem is similar to my other remarks in #4933

Hardware CAM can decode only from one tuner in same time
Only PRO devices can and have software for more.

Yes, I know. But I have 2 TT-4650 tuners with 2 CI modules. One placed in each.
Currently there doesn't seem to be a solution for this problem. The "service limit" for a cam works. If you tune for a 4th recording from another much, it will work.

Dear Jaroslav, I understand it.
But am I missing the point here? Why is there such a setting to limit the services on a CAM if there is no fallback plan to what is supposed to happen when this limit is exceeded?
From a DVR view or from a HTSP or RTSP view, the problem remains the same.
Or is this setting here for another reason?

You can let tvh to select quickly another service - see my previous comment for the workaround for DVBAPI sources (two networks). Also there might be different scenarios (like DVB-S primary, DVB-T or IPTV fallback etc.).
