vdr-plugin-ttxtsubs

I quickly checked the code and I guess the problem is in patch-set.1.7.21 in 0001-Record-teletext-subtitles.patch:

64 + tTeletextSubtitlePage(int page) { ttxtMagazine = (page / 100) & 0x7; ttxtPage = (((page % 100) / 10) << 4) + (page % 10); ttxtType = 0x02; strcpy(ttxtLanguage, "und"); }

should probably be:

64 + tTeletextSubtitlePage(int page) { ttxtMagazine = ((page / 100 - 1) & 0x7) + 1; ttxtPage = (((page % 100) / 10) << 4) + (page % 10); ttxtType = 0x02; strcpy(ttxtLanguage, "und"); }

As the teletext definition tells:

"Teletext allows up to eight 'magazines' to be broadcast, identified by the first digit of the three-digit page number (1-8)."

And the code here seems to ignore magazine 8 which is used by French TV channels. I had to still test that and check the code if there is similar limitations elsewhere.

Ok, I had some time to look at the code. The Magazine number is stored in three (3) bit field, which means magazine 8 is represented as 0. When the subtitle teletext page number is written to channels.conf no conversion is made in magazine number, so magazine 8 is written as 0, and that causes the page number to be 88 instead of 888.

I will try to make a patch set for that.

I had finally some time to look at this, and here is a work-a-round to get the French subtitles to show on TV stations that are still broadcasting the wrong subtitle page (for example 059 instead of 089).

1) Stop your vdr (eg /etc/init.d/vdr stop)
2) edit the channels.conf file by adding the subtitle page "und" (Manual/Undefined) to channels that have the French subtitle problem, eg change:

TF1;TNT:11934:VC34M2O0S0:S19.2E:27500:168=2:112=fra@4,113=deu@4,114=eng@4,115=qad@3:59:0:8159:1:1076:0

by adding +89=und (that is for page 089 = 889) to:

TF1;TNT:11934:VC34M2O0S0:S19.2E:27500:168=2:112=fra@4,113=deu@4,114=eng@4,115=qad@3:59+89=und:0:8159:1:1076:0

3) Start you vdr (eg /etc/init.d/vdr start)
4) Go to OSD menu Setup->Plugins->ttxtsubs and add as a Language 1 (the first language): Undef/Manual. Also add Hearing Impaired: yes. Put all the real languages you will be using for other channels after that.

Now you should have the teletext subtitles showing on you French channels that are not sending correctly the subtitle page.

Can you please test the current version from the Git-Repository?

Please test the live-viewing as well as replaying of teletext subtitles works with those buggy channels.

Yes it works fine!
I did finally add also the menu support selection for the french subtitles, please see Feature #957
