I fixed the EPG limit in v4.3-1252-g595fd174f and I'll look to others. It seems that the ETSI DVB SI tables detection should be a bit improved. The mentioned muxes does not have NIT SI tables which the new code expects to identify the special conditions for some non-standard EIT tables. I can receive 19.2E, so just give me a little time.

If you have access to 19.2e then you can check the issue above by tuning into 11464 H 22000. (that's the Pro7/Sat1 transponder). Not pulling any eit from there since the last few builds..

Bug is also existing in Synology build 4.4.20180311-1.

Any news on this issue, as I'm having the exact same problem?

I can confirm this, no EPG from "ProSiebenSat.1".

[ DEBUG]:epggrab: grab done for 12544.75H in Astra (no data)

Hardware receivers and built-in tv receivers can grab ProSiebenSat.1 EPG

Hi,

based on current git HEAD master branch reverting the two last commits from dvb_psi_lib.c
https://github.com/tvheadend/tvheadend/commits/master/src/input/mpegts/dvb_psi_lib.c
did not fix the problem so I guess more code needs to be reverted.

Please scratch that comment, I mixed up the patches here.

Ok, tested again with these two commits really reverted, and..., the missing EPG from the ProSiebenSat.1 group appears again Sorry for the noise.

For me, reverting the two commits fixes nothing.

Please note that those two commits are also in 4.2.6, which does not have the problem. Thus, these two commits cannot be the cause of the problem.

I can only say that for EPG problems with ProSiebenSat.1 d3fc9696299d438c9396b56bb4939bce0da6c18d (dvb psi: improve section parser, fixes #4987) is the first bad commit.

I'm at 65a44a5a7218454e3096e2d22395accb97caa50b (linuxdvb: implement correctly PID overlimit) now and I receive EPG data from ProSiebenSat.1 "again".

Looks like more problems, maybe split the "ProSiebenSat.1" EPG problem and report as separate bug?

Reverting the two mentioned commits within the latest master did solve the EPG issue for me. @Heinrich Lech: Thanks for your findings.

I pulled from git days ago and have the same problem of missing ProsiebenSat1 EPG. Any patch to try out?

This has become really annoying - any reversal of the erraneous fixes in sight?

OK, reverted both 223fb7a44ced1e9597ea46fe45b56e9174862f56 and d3fc9696299d438c9396b56bb4939bce0da6c18d and ProSiebenSat.1 EIT shows up again. But this can't be a permanent fix, can it?

+Bloombert and CNBC which where missing as well.

Err, Bloomberg

Would be so great if you could create a FORK on github and send me the URL :-)

As a workaround I use Webgrabplus for this channels, till we get a fix.

Please provide a bug fix that is supported in a build.
After this thorough analysis it cannot be that hard, can it?

For me it started to work again, all I did in meantime was update of the system (gentoo)

Why the pressure? Give Jaroslav the vacation he needs

Strangely today the problem went away and the EPG of all tv stations (Germany, e.g. ProSieben, Sat, ...) are back again.
Maybe there was a fix in the format the stations are transmitting.

same here,
However, I do hope it was not a change in the eit format on the providers side, since that would mean, that we'll now never find out what was wrong. Remember that other dvb clients were able to handle the eit.

same here, all EPG works again without an restart of Tvh in between so likely an service provider problem

Today the bug is back again.

yes for me too strange - same channels like before

Confirmed, gone again. At least we can see the issue now again.

Very strange! Reverted the two mentioned commits once again and EPG is now working as it should again.

Hey, can anyone please create a fork at GitHub?

Anyone should grab two .ts streams: One with working EPG and a second one with none-working EPG

maybe this is related to https://tvheadend.org/issues/5065

Talking about EPG:

The first week of June I had strong problems with Live-TV and Kodi as described in [[https://www.tvheadend.org/boards/14/topics/33106]]
Looking at the log-file, something seemed to be wrong with the EPG.
(biggest problem is that live-tv wasn't possible for several days, and then it returned to work perfectly,
without changes from my side)

Anyone else in Central Europe observed this problem?

Today again EPG of ProSieben, SAT1, and others is missing again.
I do not see the systematic behind these failures.

Same here - will have to revert 223fb7a44ced1e9597ea46fe45b56e9174862f56 and d3fc9696299d438c9396b56bb4939bce0da6c18d again. PITB

Some Channels that not worked before: kabel eins doku, Discovery HD, InsightTV HD, FOX HD, Sat1 GOLD HD and other ....

What do we need to do to get this fixed? Any additional data needed? It's obvious the problem was introduced by these two commits, so it should be possible to backtrace it.

I am not a programmer, but having a look at the source code of the two mentioned revisions

[[https://tvheadend.org/projects/tvheadend/repository/revisions/d3fc9696299d438c9396b56bb4939bce0da6c18d]]
[[https://tvheadend.org/projects/tvheadend/repository/revisions/223fb7a44ced1e9597ea46fe45b56e9174862f56]]

I can't see why this changes should affect the extraction of EPG data?

Besides the code the tv stations seem to change sometimes the structure of the broadcast signal. Some days it's working, other days not. I am wondering if other software like VDR face similar problems during the past few weeks?

Retest with latest.

Looks good !
Don't see any channel where the epg-data are missing.

Confirm it's working again.
Let's hope it's not the same effect as seen in post 24...36

Works for me, too. Thank you very much!

No, it cannot be the same effect because in my unpatched version channel EPG is missing.

Nice.

BTW: works for me, too

I just updated to the latests git Version 66d6161c5 and still have no EPG for ProSieben and Sat1. I did a full rescan and restarted tvh multiple times and triggered the EPG scan.

Ok, after watching the channel for a few minutes the epg information suddenly appeared. So this is solved for me too.

Works for me too
