I ran dvbv5-scan with -O vdr and it gave me the line. I manually
copied it to channels.conf. Upon vdr start I saw that VDR was updating
the PIDs. 

Here's what came out of it:

France 2:586000:B8C23G32M64S0T8Y0:T:0:120=27:0; \
   130=fra@122,131=qad@122,132=qaa@122:0;140=fra,142=fra :0:257:0:0:0

(\ and line break added by me)

Good idea. 

I deleted the channel and switched to another channel on the same
transponder.

Nothing happens. VDR does not re-"find" the channel. VDR is set up to
"Add New Transponders".

Running scan -c (current transponder) gives:

Any idea?

Re: [vdr] French DVB-T Channel IDs vs. EIT Channel IDs

Hi list,

since some time (1-2 years) I noticed that the DVB-T channels do not
show EPG anymore. I'm not sure what is the root-cause: either it
was the migration of French DVB-T to HD (in 2016) or an update of VDR.

Anyway, this morning I took the time to figure out what is wrong and
here is what I found.

In short, the channel-ID generated from the one received in the EIT
does not correspond to a known channel-ID from the channel list, and
VDR drops the whole section:

In cEIT::cEIT (from eit.c) we see

   tChannelID channelID(Source, getOriginalNetworkId(), getTransportStreamId(), 
getServiceId());
   cChannel *Channel = Channels->GetByChannelID(channelID, true);

and channel is NULL in my case.

I added some debug prints to GetByChannelID() in the search loop:

   printf("sid: %d == %d, %s, %s %d\n",
  Channel->Sid(),
  sid,
  (const char *)ChannelID.ToString(),
  (const char *)Channel->GetChannelID().ToString(),
  Channel->GetChannelID() == ChannelID);

And here is an example of what I get:

   sid: 517 == 517, T-8442-2-517, T-0-506-517 0

The internal channel ID of vdr reads T-0-506-517. 517 is the SID, 506
is the radio-channel frequency in MHz. This is the right internal
channel for this EIT-section.

The EIT-channel-ID is telling me that 8442 is the original network ID
and 2 might be the radio-channel ID.

I tweaked the operator==() of ChannelID to make it work, but not in a
contributable manner.

How should this be fixed correctly?

Is this a regression introduced somewhere?

Can it be solved by configuration?


Hello Patrick,

where did the channel with ID T-0-506-517 come from in the first place?

What happens if you delete that channel from VDR's channel list and tune
to the transponder? Does it create the channel with the correct ID?
