Unable to get GearVR MediaSurfacePlugin for Unity to play video

I had some problems trying to play the video through Oculus mobile sdk MediaSurfacePlugin for Unity. I have tried many different ideas, but come back to the same problem; It appears that the Android media player cannot find the file. These are the most common errors I received:

Unity: failed to start mediaPlayer with message java.io.IOException: setDataSource failed.
Unity:
Unity: (File name: ./ artifacts / generated / common / runtime / UnityEngineDebugBindings.gen.cpp Line: 37)
Unity:

and

MediaPlayer: unable to create media player
Unity: failed to start mediaPlayer with message java.io.IOException: setDataSourceFD failed: status = 0x80000000
Unity:
