in de flash memory of the goggles there are some demo videos, playing with audio.
some custom mp4's with simple audiostream in it, put on a SD card and trying to play them through using local storage, will work, but without audio !
WHY !!! what codec is supported.
In that way I can compile some of my drone footage, adding some music to it, and play back on the goggles.
How can I make this work ?

I want to know it too. Same problem for me. And Second problem is with photos. When i want to watch some edited JPG i can see just a preview, but cant open that pics.
