   Hi Carlos,   
      
   Yes. VLC is behaving normally on your phone. On Android, VLC supports   
   background audio by default but not background video.   
      
   Android pauses video when the screen turns off unless the app runs a   
   special foreground video service but VLC apparently does not implement it.   
      
   That is why audio continues but video stops. I could be wrong but I looked   
   it up and there is no VLC setting to change this. As I noted in my response   
   to Nick, some Android apps (like NewPipe) do support screen-off video, but   
   VLC intentionally does not, where I can't blame them as, at least on   
   Windows, it's easy to rip the audio out of a video using the VLC freeware.   
      
   Carlos is on Linux where VLC for Android supports playing the audio track   
   of a video in the background, but Android (or iOS) VLC apparently does not   
   include any feature to save or export that audio as a separate file.   
      
   Unfortunately, the iOS/Android VLC lacks the "Convert/Save" functionality   
   that exists in VLC for Windows, macOS & Linux where we can rip easily.   
      
   With that in mind, here's a summary of background audio with no screen.   
      
   Android with the screen turned off:   
    a. Background audio: Allowed   
       But only if the app implements MediaSession + foreground service.   
    b. Background video: Not allowed   
       Unless the app implements a special foreground video service (rare).   
    c. VLC: Audio continues while video stops.   
      
   iOS with the screen turned off:   
    a. Background audio: Allowed   
       But only if the app declares the audio background mode.   
    b. Background video: Never allowed.   
    c. VLC: Audio from video is not reliably allowed as iOS often suspends it   
       (based on reports that I unearthed in researching this for iOS)
