After playing a local file in Oculus Video v. 2.48.10 (usually 180° or 360° stereoscopic) one or a couple of times, the Oculus Video app becomes unresponsive during any other video playback (the video plays in slow motion and the GUI stutters), and even the Samsung VR app can't play any videos at all afterwards. Files that play just fine on the Samsung VR can trigger this problem on the Oculus Video.
I've been able to reproduce this issue 100% of the time on two different devices:
A short video sample that triggers the problem can be found here: Clip-Ghost in the Shell VR_3dv_360_TB.mp4
Steps to reproduce the problem:
- Download the file into the phone and insert the phone in the Gear VR
- Open the file using Oculus Video, and it should play normally (only the 1st time) in 360°, stereoscopic mode.
- Play the video a 2nd time. It might play normally again at least on the S7, but already becomes glitchy on the Note 4.
- When playing the video a 3rd time, the Oculus Video app becomes very unresponsive during playback (including the GUI). It can't play correctly almost any video, unless the phone is removed from the Gear VR and reinserted.
FWIW, here are some technical details about the video file (from ffprobe):

I also captured some basic performance stats via logcat
on the Note 4, available here: N4_logcat_VrApi.txt
. From it one can see how the performance has dropped dramatically.
The problem happens even in airplane mode, after rebooting the device, etc., and both devices uses stock ROMs (none has root), have up-to-date software and OS.
I'm still investigating the logcat to see if I can find anything else interesting to share.
Does anyone else have the same issue?
