Not adding service to a Mux

Added by Steve Murray about 12 years ago

Just switching to tvheadend from MythTV (with XBMC frontend) - overall seems lots more simple, but provides the key functionality I need.

I seem to be having problems though adding all the services.

from w_scan, I get the following on mux frequency 10,964

Channel 5;BSkyB:10964:hC56:S28.2E:22000:2305:2306,2307=eng:2308:0:7700:2:2057:0
Channel 5;BSkyB:10964:hC56:S28.2E:22000:2346:2347,2348=eng:2349:0:7701:2:2057:0
Channel 5;BSkyB:10964:hC56:S28.2E:22000:2313:2314,2315=eng:2316:0:7702:2:2057:0
Channel 5;BSkyB:10964:hC56:S28.2E:22000:2317:2318,2319=eng:2320:0:7703:2:2057:0
Channel 5;BSkyB:10964:hC56:S28.2E:22000:2309:2310,2311=eng:2312:0:7704:2:2057:0
5 USA;BSkyB:10964:hC56:S28.2E:22000:2325:2326,2327=eng:2328:0:7710:2:2057:0
5 USA +1;BSkyB:10964:hC56:S28.2E:22000:2333:2334,2336=eng:2335:0:7711:2:2057:0
5*;BSkyB:10964:hC56:S28.2E:22000:2329:2330,2331=eng:2332:0:7715:2:2057:0
5* +1;BSkyB:10964:hC56:S28.2E:22000:2337:2338,2340=eng:2339:0:7716:2:2057:0
Channel 5+1;BSkyB:10964:hC56:S28.2E:22000:2321:2322,2323=eng:2324:0:7720:2:2057:0

However, tvheadend finds nothing on this mux, although shows it as a good signal.
Here is the dvbmux file: which as far as I can see, matches with the channels.conf output from w_scan.

{
"quality": 100,
"enabled": 1,
"status": "OK",
"transportstreamid": 2057,
"network": "ASTRA",
"frequency": 10964000,
"initialscan": 0,
"symbol_rate": 22000000,
"fec": "5/6",
"polarisation": "Horizontal",
"modulation": "QPSK",
"delivery_system": "SYS_DVBS",
"rolloff": "ROLLOFF_35"
}

Is there any way to manually create these channels, force re-scan, or fix some other way?

It's funny you should say that! I've been having trouble getting my own setup to find Channel 5 (but I never watch it so not looked into it yet).

I'll try and take a look and see what's going on. Unfortunately you cannot manually add services they're auto added (or should be) from the PMT. The only way to manually add would be to manually generate teh config files but you'll have to figure that out yourself if you want to do it.

Thanks Adam, appreciate the quick response.

She'll just have to make do with previous recordings for now - ha ha.

Ok,

I think I've found the problem it relates to a long standing issue that we have. My setup has 2 muxes added for the same TSID one with a slightly different frequency to the other. Unfortunately if this happens it looks like it completely fails to use either entry.

It's all to do with the way TVH currently handles the same mux (i.e. same ID) but with potentially slightly varying frequency info, it should really merge them but it creates 2 distinct entries and this causes several problems.

The simple solution is to find the duplicate mux and mark it disabled (if you remove it also make sure you disable auto mux discovery). The more general problem will unfortunately not be resolved until after release 3.2.

A quick update, I'm not sure disabling the mux is enough. Therefore you will need to disabled auto mux discovery and then delete 1 of the 2 muxes (if that's your problem). I'm hoping to do some work on the core DVB structures post release 3.2 that will hopefully resolve this issue.

Thanks for your help - that did indeed fix it.
