Description

EPG is not collected for viasat_baltic channels any more.
I tried different versions, last working version is 4.3-1036~g4d1955080 (commit 4d1955080d55da8b43599eff8bcd4dadc2dc38cd).

How can I help to debug this issue?

I removed all the channels except Viasat Explore. Enabled --trace tbl-eit,epggrab.
Started tvheadend, epggrab was running some time, once it finished only 2 records are shown in epg page. Version 4.3-1036 had much more rows. Also, next epggrab won't add new records, this means that once those 2 records expire there will be no more EPG data.

It seems that EIT events are seen, but skipped for a reason:

Suspicious line: https://github.com/tvheadend/tvheadend/blob/master/src/epggrab/module/eit.c#L995

Attach .TS (30 seconds) or investigate the problem in the code.

Edit:

For some reason file upload gives error (tried multiple times). Anyway, I have uploaded it to onedrive, file can be downloaded using:

wget "https://onedrive.live.com/download?cid=F79C3A33AD71C0A9&resid=F79C3A33AD71C0A9%2125834&authkey=AI7A-moyrOPTQYk" -O sample.ts

Today I tried version 4.3-1288~g66d6161c5 and I noticed that other channels (beside viastat baltic stuff) have also similar issue. Eg. MTV Hits (thor 0.8w 12226V ServiceID 508), after tvheadend restart only 2 records are collected.

data/conf/epggrab/eit/config needs to be corrected to:
"viasat_baltic": {
"name": {
"eng": "VIASAT: Baltic"
},
"nit": {
"AMB": { "nbid": 85 },
"Viasat": { "nbid": 86 }
},
"pid": 57,
"prio": 5
},

details:
pid is 57, in source code its 37 which is developers typo error
nbid:85 now network name has chaged to "AMB".
This fix solves EPG problems. (EPG sits on 11785V freq)
