When viewing a VR 360 clip that I downloaded from pc to the Oculus Go, the video kept stopping and the following error message would appear: "Oculus App runtime has stopped". It would then give an option to reopen and then the video would play from where it left off. But then it would stop again with the same message.
We’re also having this same problem with a monoscopic 360 4K video in .mp4 format that we sideloaded yesterday - we’re getting audio delay issues, white “flashes” in alternating lenses, and the oculus runtime is crashing. We’ll try to find and post the log files later today.
@riggo88 I found that the Samsung VR app was able to play my video properly - hopefully that helps you while we're waiting for a fix from Oculus for the gallery.
