I have mp4 movie file with 5.1ch audio. "Gear VR Gallery" app with yellow flower icon give me 3D spatial headtracking audio experience when I play the mp4 file.
But, Mobile SDK Sample app(Oculus 360 Videos SDK) don't have 3D spatial headtracking audio ability. Can I add it to Mobile SDK Sample app by modifying its code?
I'm facing the same issue. Of course it's best to use Androids native media player to play the embedded audio in the video file to have perfect sync. But I'm also in the dark how to get that audio spatialized using the realtime head-tracking.
