Feature description

My plan is to add a new option under Video and audio/Behavior, which would look like this:

Ignore headset media button presses  
Notice: In the case of a Bluetooth headset, all media button events will be ignored, which breaks the Media Control UI in the notification area

When the option is enabled, it should do precisely what its description states.
Because it is impossible to distinguish between events that come from a Bluetooth headset and the control UI, it will ignore events from both sides. However, this should only occur when a Bluetooth headset is detected.

Why do you want this feature?

I sleep with my headset on. However, I often press the prev/next track buttons on the headset by accident, which causes the video to rewind or skip. Needless to say, this is quite inconvenient.
Unfortunately, on Android, there is no way to disable media buttons globally without rooting the phone or physically blocking the pin (which also disables the mic). This means I need the option to make the player ignore those presses.
I'm planning to implement it myself today. But I would also like to know if someone else is interested in such a feature.

This seems to be a nice feature. But combining with #7880 would be better.

there are two separate settings, one for NEXT and one for PREV, each button can be assigned to any of four functions:

PREV (Restart Episode / Video)
NEXT (Skip Episode / Next Video)
FFWD (Fast Forward)
REW (Rewind)

There should be a fifth option None.

Not sure how to reassign buttons on Bluetooth headsets though. Oh yeah, and someone with a Bluetooth headset will have to test if the patch works
Almost done with the patch now, the experience with VLC made it quite straightforward. Give me maybe another half hour

Oh, great, I woke Checkstyle up. This is gonna take longer than what I expected...
Umm, the patch didn't work. Hofstadter's law is kicking in...

Nailed it! https://github.com/NyanCatTW1/NewPipe/commit/f75003732c2639457d01638493d8f41072a59ed9
It turns out that I should've set the media button event handler of MediaButtonEventHandler. A good side effect is that this for some reason doesn't block actions from the media control UI, which means the UI should work even with a Bluetooth headset!

Making a PR right now
Also, once the PR gets merged, it should be fairly straightforward to implement #7880 inside MediaButtonEventHandler.java

No problem, that could be done as well. I just suggested combining the options to avoid a bloated UI.
