this is not Doğuş Media Group, it is Discovery, Inc.

If made correctly, this should be a new plugin and not be added here.

edit:

@back-to
The HLS streams are on this hostname though dogus.daioncdn.net

@back-to Discovery group's partner in Turkey is Dogus group. Ntv Spor channel changed its name to D Max.

I'm from Turkey. I made such a request because Tlc and D Max had organic ties to the Doğuş group.

You can delete my request to pull. I just wanted to help. Sorry. I should've kept it to myself. Good bye.

Maybe the existing tlctr plugin should be removed then?

@omergorur, you should also update should_match[] in test_dogus.py with the two new live channel URLs you have added to the plugin.

Tlc and D Max had organic ties to the Doğuş group.

The sites themselves don't say anything about that:
https://www.dmax.com.tr/bilgi-toplumu-hizmetleri
https://www.tlctv.com.tr/bilgi-toplumu-hizmetleri

Wikipedia however has a link to
https://web.archive.org/web/20160207123904/http://www.digitaltveurope.net/440191/discovery-launches-tlc-in-turkey-via-dogus-partnership/

So if we're going to merge this, then either

• tlctv.com.tr would need to get removed here, as there's already the dedicated tlctr plugin. That would however make adding dmax.com.tr here questionable, as it uses the same logic for extracting the stream URLs
• or the dedicated tlctr plugin would have to get removed, which would require a rebase/cleanup of this PR, as we're not going to merge multiple commits on top of the required separate plugin removal commit. I can clean this up though, as long as I have write permissions on the repo branch of this PR.

@back-to plugin removal or not?

plugins.turkuvaz: add vavtv

I dont create smoothly another pull. So sorry

@omergorur, yes, what you did before (creating another PR for a different plugin modification) is fine and generally preferred.

@omergorur, it may help you to read https://streamlink.github.io/developing.html and https://streamlink.github.io/developing.html#validating-changes in particular so that you can lint the changes you make before pushing them to GitHub and check the tests as well.

startv seems to work without any changes
