Interesting - this time when USB disappeared from the app, I tried VLC again - worked fine. But USB is still gone on the app. So I don't know what that means - some kind of problem with the app ? Not sure. The MiniDLNA server itself is clearly working just fine right now. And if I use the app to start playing the song that I had paused before - that still works too - it plays on my speakers. It just does not show USB as a source in the app. Very strange. (while the song is playing on the app, the icon at the bottom for the server is greyed out)I was wondering if they'd exposed that.
I'm pretty sure that's all there is unfortunately, at least from the core project.
Would be nice to get some logging, even if it's only the errors written to a log file on the USB.
The app does appear to have some log files on the phone but I can't seem to access them.
