[Zgemma H7] Weird EPG errors. EPG Refresh. Recent versions of OpenViX e.g. 5.4.008.

[ronand]

I deleted my epg cache and did a forced opentv download and the data was badly corrupted. Most of the descriptions were missing and some short descriptions were just random characters.

I get that occasionally. Many missing program titles, just the times.
I have the impression that it's caused by some kind of data corruption that is hard to get rid of. I typically repeat two or three times deleteing the EPG cache and rebooting and that fixes it.

I've seen that too, particularly when I'm testing (doesn't seem an issue if I just let the OpenTV scheduler do its stuff). Sometimes I've had to create a epg file to break the cycle.

Example 6th March 2021, running 5.4.088, Xtrend ET10k

Grid EPG where the double entry is on CH4 HD



Alternative EPG view showing two programms in the same time slot



The embedded program (big fat quiz of everything) was broadcast the previous evening although it seems to be repeated often.

I have both CH4 and CH4 HD in my 28.2E Bouquet and both CH4 and CH4 HD EPG have the same problem

Ch4 EPG




I also have tuners set for terrestrial UK Freview and the the EPG for CH4 from Freeview (EIT) does NOT show the same problem.

Have you got Freesat and Opentv enabled at the same time?

Could this be cache issues? If so, any value to adding option to delete cache before it downloads epg data? Happy to try code it in as a PoC

Quick look at CrossEPG and it looks like it deals with epg cache via new cache instance!

You would need to only delete the channels being downloaded, and also would have to occur for all types including eit.

Step one would be log everything that is ever downloaded to find where the conflicting data is coming from.

No,

What about epg.dat after booting from deep standby? It will hold out of date data which will need flushing out.

Works ok on freeview eit though, I always use deep standby overnight.

 

[Huevos]

These strange overlaps have always existed, and must be in PLi too because the code is identical.

If we want to go anywhere with this the only way to make progress is to do what I said above and log absolutely everything that enters the epgcache.

 

[BrokenUnusableAccount]

I've fiddled with EPG Refresh and I now have it doing OpenTV first, then Freesat and then Freeview, and I'm going to see if that makes any difference.
So far I think it does seem better.

No doesn't seem to make much difference.

I will try with Freesat EPG switched off next.

I've seen the problem on 28.2E with all combinations of EIT, Freesat and OpenTV and with using OpenTV EPG downloader, EPG Refresh and with just switching to IEPG at 6:30am for 10 minutes.

The main problem with fault finding is that the problem is somewhat intermittent. Some days no problems are seen, some days only one channel has the problem and on other days it may be six channels with double entries.

I cannot establish a pattern but its often the first few timeslots (in the first 2 to 3 hours) in the EPG referenced to the time I manually turned on my box from deep standby but having said that I have many autotimers set-up that set timers at various times during the night/day that will switch the box on for recording and presumably re-trigger some of the EPG fetching mechanisms.

 

[BrokenUnusableAccount]

My box is set up to never go in to deep standby - I theorise, rightly or wrongly, that it's likely that regularly starting up again from deep standby would stress it more than leaving it in normal standby does.
Plus occasionally I stream from it to my laptop and it's nice not to have to start it up first.

I think Running EPG Refresh soon after midnight gives the most weird extra EPG entries and soon before midnight the least, or maybe none.

I will try with Freesat EPG switched off next.

Not much different with Freesat and EIT EPGs switched off.

 

[bbbuk]

I noticed odd entries like this while back when EPG Refresh was in default Vix image (before days of OpenTV zapper). I then went back to CrossEPG and dont notice anything anymore except actual odd last minute changes that are picked up by EIT (and to be expected).

I have ABM scan 6am daily with CrossEPG 6.05am daily.

That's the impression I get - old data getting flushed out from "yesterday" while it's running perhaps?

 

[adm]

This morning at approx 8:30am when I switched on (and for at least 15 minutes afterwards) the entry for "Live Cricket, England v England" on 28.2E Ch4, 28.2E Ch4 HD and Freeview Ch4 was missing and on the grid EPG the highlighting of that time slot had the same problems as seen when there is a double entry. Two hours later when I checked (box left on) the missing entry had been populated on both 28.2E and UK terrestrial Freeview.

 

[ccs]

Live cricket ended yesterday , so that was probably a change of schedule.

I'm seeing ""Sunday Brunch" on CH4 freeview (originally scheduled to start at 11:45).

I wonder when the change of schedule actually happended?


I've got a copy of epg.dat from 22:09 last night when the box shutdown, I'll see if it's in there.

There's one entry for "Live Cricket: India v England:", there should have been 2 (today and tomorrow) if the game hadn't ended early,
so the schedules on freeview partly changed yesterday.

 

[ccs]

I know freeview is ok, but here goes.

I've booted up my et10k from deep standby (closed down last night) with no tuners connected.

epg.dat from last night shows a change of schedule for the cricket today and tomorrow (and also has one entry for "Live Cricket: India v England:" using notepad++).

So at 8:30am my EPG entry was blank for that Ch4 and Ch4 HD time slot

Before posting this (and before trying a new forced update of EPG data) it was showing ....



But as you indicate the Cricket has finished (I have zero interest in Cricket so I haven't actully been watching Ch4 during those times). Live:Sunday Bruch is still scheduled for 11:45 to 14:45

Pressing blue and forcing a openTV EPG download DID NOT update the entry for this current listing nor the next time slot which must have also changed.

I now seem to have problems with 28.2E EPG updating even after a Cache delete and a couple of reboots

Edit Update


After a EPG Cache delete and a reboot the 28.2E data didn’t update after a press blue and selecting a forced opentv download

After a EPG Cache delete and a mains power shutdown the 28.2E data didn’t update after a press blue and selecting a forced opentv download

After a EPG Cache delete and a mains power shutdown the 28.2E data didn’t update just leaving the box for 10 minutes.

In the end I reloaded a delete EPG plugin and used that to stop Enigma2 to delete EPG files. After a reboot the 28.2E EPG repopulated within 10 minutes.
