I have lots of 3d videos on my Zyxel NAS 540. I have 5 GHz ac mode wifi access to them with my phone. I am using another software to play them now, but your player produces better orientation / scale for videos. As soon as that feature will available in fulldrive, I will stop using other app.
I also need this feature. I store my content on the network share on my Windows PC and I would be happy to consume it using Fulldive. If it is important, Xiaomi VR Play app can play videos from the network share(but can't browse it, I use ES Explorer for this).
