Describe the feature you want

I'm using a cheap mobile data plan with 400MB per month included. That's way enough for me - except the case my phone loses WiFi when watching video and eats up a large amount of data in a few minutes - and I don't even notice. It would be nice if I

• either could just limit NewPipe to WiFi-only operation
• or opt for an alert in case WiFi is lost

Optionally, also describe alternatives you've considered.

There is additional software for this, see #355. But with restricted SD card size, you want to avoid any additional bit of software.

Is your feature request related to a problem? Please describe it

In #355 the same issue is covered about downloading. But I think it's about watching as well.

How will you/everyone benefit from this feature?

Finding that NewPipe ate up a large fraction of the data plan - for nothing, just by accident - is frustrating. So it would be great if we could ensure that does not happen.

In case there already is a solution I could not find, please apologize - and give me a hint.

We could switch to audio only and show a warning that wifi has been lost and switch back to video+audio once wifi is recovered. Or would you rather like to stop playback completely?

[herrdeh]

Wow - such a quick reply! (-:
I'd be happy with both solutions - a switch to administer would be the de-luxe.

meanwhile you could set your preferred video resolution to 144p when on mobile. This will probably be very notable and also consume less data.

Thank you for pointing me to that control - hadn't noticed it before. Extending it with the options "stop playback" and "playback audio only" should do the job. A default setting as "stop playback" with an alert - "playback stopped because WiFi is lost - change settings at..." would make it close to dummy-proof (meaning: suitable for me}, I assume.

Adding a setting just for this would be niche for most users, cluttering the logic. Installing another app shouldn't use more than 2-3MB. Adding this to NewPipe is out of scope, sorry

[herrdeh]

Can't agree. Everybody is in risk to loose WiFi occasionally. And another setting for behaviour at WiFi / mobile is a breeze.
