Description

I am getting errors for one of my channels, constantly, without stopping. But these errors are only shown on Stream tab not on Suscription for the same channel and time.

It looks like some kind of visual bug (?).

I have also verified that when this happens to the channel I can not disable the service in use, because the service checkbox is blocked and returns to its active state after clicking.

Increasing by steps of 2 cc erros per second on stream tab:

0 erros at Subscription tab at the same time:

And log is clean:

P.S.: Attached log (--trace tbl,tbl-base,mpegts)

disable auto refresh on bottom
if other browser is logged need also to be stopped there /auto refresh/

It does not matter, the same thing happens

Looks like the cc errors are in the PMT itself and not in the video/audio streams, so probably that is why it is not showing up under subscription?

It is strange, stream comes from another tvheadend in which no errors are shown in any of the tabs. Also rewrite is fully activated > 1

And if you disable all rewrite?

i have a similar problem when using 4.3-1663~g552cea0fc as a bridge server for my iptv services, first of all, the stream starts almost always with some art effects and later there are noticeable errors in the stream. Now I'm using 4.2.7-35~g44ac78d as bridge and that just works fine.

It's for HLS streams?

No, it is a common stream! DVB-T on tvh1 and tvh2 (the one who has errors) through IPTV.

I have tried it on my PC and other devices and it always happens with that channel. Thing that had never happened before, it does not matter if restarting tvh; it is still happening.

No, it's something different, two TELETEXT descriptors in PMT with the same page:

After this commit Teletext doesn't work anymore for me.
If i reverting commit d07a12e013c8bff2e59accb9d948fddd8488389d it works again.

Andreas, what exactly does not work ? Teletext in VLC or kodi or text subtitles ? What is your 'service info' (the info icon in the service grid) for the non-working service ?

Didn't try in VLC but in Kodi.
It shows all Teletext streams but it doesn't show the subtitles.

With Teletext streams i Teletext subtitles.
I can recompile and check again later but i think it shows everything there because Kodi found all Teletext subtlte streams.

I see it. Fixed in v4.3-1695-gb17dcf914 .
