1 Tvheadend - Bug #2580 services get disabled when "missing in PAT" :03 - Rob vh Status: Fixed Start date: Priority: Normal Due date: Assignee: % Done: 0% Category: DVB Estimated time: 0.00 hour Target version: Found in version: , Affected Versions: Description In the last weeks, BBC 4 HD gets disabled repeatedly, thus I miss recordings (repeatedly). In syslog I see messages like Dec 27 15:47:03 sat tvheadend 4881 : mpegts: 10847V in 28.2E - tuning on STV090x Multistandard : DVB-S #3 Dec 27 15:47:03 sat tvheadend 4881 : subscription: 000A: " [ XBMC Media Center ]" subscribing on "BBC Three HD", we ight: 150, adapter: "STV090x Multistandard : DVB-S #3", network: "28.2E", mux: "10847V", provider: "BSkyB", service: "BBC Thr ee HD", hostname=" ", username="<n/a>", client="xbmc Media Center" Dec 27 15:47:04 sat tvheadend 4881 : subscription: 000A: " [ XBMC Media Center ]" unsubscribing from "BBC Three HD", hostname=" ", username="<n/a>", client="xbmc Media Center" Dec 27 15:47:04 sat tvheadend 4881 : mpegts: H in 28.2E - tuning on STV090x Multistandard : DVB-S #3 Dec 27 15:47:05 sat tvheadend 4881 : subscription: 000B: " [ XBMC Media Center ]" subscribing on "BBC Four HD", wei ght: 150, adapter: "STV090x Multistandard : DVB-S #3", network: "28.2E", mux: " H", provider: "BSkyB", service: "BBC F our HD", hostname=" ", username="<n/a>", client="xbmc Media Center" Dec 27 15:47:05 sat tvheadend 4881 : mpegts: disabling service 28.2E/ H/BBC Four HD (missing in PAT) Dec 27 15:47:14 sat tvheadend 4881 : mpegts: H in 28.2E - scan needs more time Dec 27 15:47:26 sat tvheadend 4881 : mpegts: H in 28.2E scan complete Dec 27 15:47:28 sat tvheadend 4881 : subscription: 000B: " [ XBMC Media Center ]" unsubscribing from "BBC Four HD", hostname=" ", username="<n/a>", client="xbmc Media Center" Manually enabling the service works, for a few days. Then "missing in PAT" reappears :-( This happens for more services on 19.2E and 28.2E History # :57 - Rafal Kupiec Yes, thats annoying... You can avoid that by editing service with 'missing in pat' and disable automatic checking for this specific service. Anyway, when there are a lot of such services, this is still like a pain in the ass, TBH. So imho there should be option, to disable automatic checking at least per MUX. # :20 - Rob vh Thank you for the workaround... This "issue" didn't occur a month ago and also, it seems to happen for some services more than others, e.g., I've lost BBC 4 HD twice now (and I see that BBC ARABIC, BBC CZ and BBCW SERVICE are gone too) but so far did not lose any other BBC service. I wonder if it is, dare I say, some unforeseen side effect in the code ;-) /5

More cons than pros... # :51 - Jaroslav Kysela # :33 - Rafal Kupiec # :13 - Jaroslav Kysela I added also SDT table checks to v g1f62c46, so the service will be disabled only when it's missing in PAT and SDT now. # :16 - Jaroslav Kysela Your logs contained data from another transpoder, so almost all parsers worked incorrectly, because it's serious bug in other layer than tvh..

You may try to use multiple tune requests to solve the tuning issue. Its not helping out. And it will be missing in PAT and SDT then. So best option is to avoid auto disable such services... # :59 - Anonymous # :16 - Rafal Kupiec Now lets imagine there are 20 muxes, each providing 8 services, that are caused by this. # :14 - Jaroslav Kysela /5

4 Now lets imagine there are 20 muxes, each providing 8 services, that are caused by this. Rafal, your environment is broken somehow. I have 9 sat positions and DVB-T without these symptomps. If you don't like it, just comment it in the source code. Add 'return' to the mpegts_mux_scan_service_check() function - src/input/mpegts/mpegts_mux.c (line 864). But for standard users, I don't see any reason to keep enabled the services which are not broadcasted and other - special - services can be excluded from this check but one by one now. # :10 - Rafal Kupiec Now lets imagine there are 20 muxes, each providing 8 services, that are caused by this.

But i have never say that this option should be disabled. Just that users should have a choice per MUX, as I dont seem to be the only person having such issues (most probably due to broken hardware / driver)... # :43 - Rob vh with , I no longer see BBC 4 HDs and friends going "disabled" so it looks like your algorithm to check SDT in combination with PAT was correct. # :47 - Jaroslav Kysela - Status changed from New to Fixed # :18 - Tom W The problem is still there. I see hundreds of enabling/disabling messages within seconds. It is really strange that the service gets enabled - and immediatly got disabled again. I do not see any problems with the reception signal: no Continuity errors, no problems except the autodisabling. The "Autodisabling" of services is - aeh - extremly unexpected T11:00: :00 server tvheadend1875: mpegts: enabling service Kabel Schland/450MHz/rbb Berlin HD (found in PAT) /5
