Hi all,

I'm running Kodi 20.2 "(20.2.0) Git:20240304-nogitfound" with NextPVR backend and an USB tuner in a Linux x64 machine. Live TV works great but teletext doesn't work nor closed captions (I don't know if this issue is related). The first time I tune a channel and access to teletext it shows nothing, only the TV. Next I exit to TV and entry again in teletext: it shows nothing again but this time I can see the lower 4 colour bar with quick access to pages.
I have do several things: change Kodi mask, change renderer, ... without success.
Next I paste the Kodi logs explained:

Thanks in advance.

NextPVR just passes the complete stream to the Kodi video player so if there is an issue with teletext you probably need to open this as a developer issue on GitHub.  There are several complaints about the telexext support in Kodi if you search the forum.  You are using an obsolete version of Nexus and Omega is now released so your best bet is to upgrade to the current release before you post the full logs (not snippets) that are required.

If you provide link to a sample recording with teletext I can have a look make sure the issue isn't related to the bad video configuration your snippet indicates.

For North American enabling closed captioning is relatively hidden in Kodi but if you search the wiki you should find out how to enable it.

As a work a round use Tvheadend as backend ( tvh does som ”muxing” before sending to Kodi . Subtitle works on live tv and recordings👍

[emveepee]

Bad advise but it is hard to avoid hearing from TVHeadend fanboys.   Subtitles etc do work with NextPVR and Kodi and closed captioning would need to be enabled with TVHeadend too.

Teletext is quiet different

Thanks for your answers. I'll send you a record as soon as possible.

OK great.  When you post it let me know what default Teletext page # you prefer.

Hi again,

a few days ago I recorded several minutes from a live TV program. Next I tried to play in several players and PCs but I noted that there's no teletext nor closed captions. I think that NextPVR is the "blame" but I cannot find any clue to say this ...
I'm trying to upload a piece of recordings to this post but I've tried to play in VLC: it plays fine but there's no teletext nor closed captions.

Regards.

As I posted NextPVR captures the entire transport stream as output from libdvb.  I don't really want an attached "piece", I will need at least one minute of a broadcast that you feel should have teletext included.  You should be able to able to use Google Drive OneDrive and provide a link or there are sites like filetransfer.io which allow large transfers.   Just start a recording and cancel it after one or two minutes.

This is a sample recording:

I hope it helps. Thanks.

Sorry, I pasted bad. Next the correct:

Thanks,  it's too short a sample for real testing, but I am not seeing any data for telextext page 202 (you never answered what page you want) or the 2 DVB subtitle tracks.

|  0x00CA  Teletext (spa, qaa, Initial Teletext page, Te  C            0 b/s  |
|  0x019B  Subtitles (spa, DVB subtitles, high definitio  C            0 b/s  |
|  0x019C  Subtitles (qaa, DVB subtitles, high definitio  C            0 b/s  |

Are you confident that this show has data?

Martin

[Tnix]

Yes, I recorded with Kodi from NextPVR recordings. Teletext is enabled in Kodi and as you said NPVR passes all the data stream. Am I missing something?

I'm recording at least 10 min and I'm uploading again.

Thanks again.

[Tnix]

Again ... Althought I'm still watching nor teletext nor closed captions ... I don't know ... Is there any setting on NPVR I'm missing?

[emveepee]

Yes still no subtitle or teletext data in the stream just video and audio, this show has descriptive audio. Probably best open a post of the NextPVR forum with the NextPVR logs so sub the author of NextPVR can participate.  Personaly I'd like to see a full mux capture just to see what is there but that kind of support is out of scope here on the Kodi forum and better on the NextPVR forum.

And no there is nothing to configure in NextPVR since it just passes of the data that the Linux library provides and there are no errors in the stream itself.

Martin

I'll try other ways to solve the issue.

Thank you very much for your help.

Regards.
