SMB streaming stops after switching focus

[cfbob]

I'm on a Windows Phone, VLC set on ''always allowed'' on the OS battery management. I can connect and browse my network share alright, but whenever i switch app or turn off the screen, VLC stops streaming the song/movie. The instant i bring VLC back to focus it continues normally. Android VLC behaves normally under the exact same situation.
Any ideas on what is going wrong?

Hi cfbob,

Which Windows Mobile OS are you running, 8.1 or 10?
What's your app version?

Hi! it's the latest in both, Vlc 3.0.3 and Windows Mobile 10 (15254.489 version from 3-4 days ago). The exact same behavior was present in all previous app and OS version though. I also had a hard reset done at some point - and reinstalled everything from scratch: no difference.

Hi cfbob,

Yes I can reproduce. But weirdly it's fine with the debugger attached.

Anyhow, the thing is that the UWP (Windows 10) platform blocks network communication by default when backgrounding/switching apps/locking the screen.
I could work around that with a regular app with networking code written in C#, but UWP does not offer a way to allow native C (libvlc) code in the background so I'm out of luck, as far as I can tell.

The chromecast feature suffers from the same issue, I'm afraid.

I don't know how to fix this right now.
