This app is a remote control for JRiver Media Center (MC) software running on a computer (we have no affiliation with JRiver, Inc.).  It also can play back media from the MC library locally to the device.  It is a music player for Android Auto as well.  It supports video, audio, and images on Android TV.

Notes:
- To customize the library items that you can browse edit the MC options: "Tools | Options | Media Network | Advanced | Custom views for JRemote, Gizmo & Panel..."
- To have a custom root view for Android Auto (e.g. just browse audio, group artist by letter, etc.) create a root library view named "Auto" in the same options as above
- Cover art is intentionally missing from screenshots but will display properly in the app with your library
- If you are experiencing unexpected playback STOPPING when playing to the device with the screen off, disable BATTERY OPTIMIZATION for the MO 4Media app: search for "battery optimization" in settings

Android TV:
- To have custom root items on the main screen create a root library view named ATV as described in Notes above.
- Chapters: Default "chapters" are generated every 5 minutes.  You can have specific timed and named chapters by importing a .xml file into your library and setting the Name tag as "VIDEONAME_Chapters" where VIDEONAME is the exact Name tag of the target video for the chapters.  The schema of this xml file is that which is produced by extracting the chapters from an MKV file with mkvtoolnix.
- Backdrops: To have a backdrop show on the file details screen import at least one image file into your library and set the Name tag to "MOVIENAME_back" or "SERIESNAME_back" where MOVIENAME is the exact Name tag of the target video for the backdrop (SERIESNAME is tv episode series name).
