Please add compatibility with Navit.

I believe that Navit uses the TRAFF format for traffic information. TraFF is an XML-based format. Links: https://traffxml.gitlab.io/ https://www.navit-project.org/ https://wiki.navit-project.org/index.php/Traffic_in_Navit

Pull Requests are welcome of course.

If you have documents about TPEG, please share them with us.

I don't know any free or open source software which can extract TPEG data from the DAB stream.

See https://github.com/navit-gps/navit/pull/766

Obviously free-to-air TPEG services are only available in Germany.

@mvglasow is an expert and will confirm even implementing via RDS was really not easy.

And in General, it's similar to https://github.com/AlbrechtL/welle.io/issues/501

From what I understood is that traffxml is a format to exchange traffic information. It can be used to transfer this information to other apps like Navit.

But to use that we need a TPEG decoder that we don't have. Do I'm right?

Yes, a TPEG decoder is needed. Slightly off topic: There are two different TPEG services in Norway, one unencrypted by NRK and one encrypted by v-traffic.

If anyone knows a TPEG decoder please let us know it.

They are working on it, but they need open unencrypted TPEG raw data: https://github.com/JvanKatwijk/qt-dab/issues/156

Lets see how Jan (@JvanKatwijk) proceeds with his activities.
