Hi - First, I love the app you've done a great job with it.
Around a week ago around half of my local vr video files (mp4) became unplayable. The unplayable files don't show up any more in the default "All Files" view even though they are there on the disk. If I click on Directory and navigate to my movies directory, all the files are listed, but some of them have a grey MP4 icon instead of a thumbnail image. If I try to play one of these it just goes black for a few seconds and then returns to the directory listing and a popup says "Invalid media file". All of these files play fine in VRTV, and used to play in Skybox up until around a week ago (not sure exactly when, but recently).
I'm on a version 1 Pixel XL, Android 8.1.0, Skybox 0.1.7.1.
Come to think about it, maybe the problem started after I updated to Android 8.1.0, it was around that time.
