Support Low Overhead Mode on Oculus Quest device
Summary
I recently bought the vlc for unity (Android) in the unity assets store. I'm trying to run a VR program on my Oculus Quest device. Firstly I only compiled the minimum playback demo and it was working fine with no error on my Android phone. But when it came to Oculus Quest, the video was playing with no video frame and the logcat showed there was a problem with EGL initialization:
E/libEGL: eglGetFrameTimestampSupportedANDROIDImpl:2604 error 300d (EGL_BAD_SURFACE)
E/VLC: [0000007e10462c00/3b03] libvlc video output: video output display creation failed
E/libEGL: eglMakeCurrentImpl:1084 error 3009 (EGL_BAD_MATCH)I'm pretty new to gles and vlc. What can I do to play my videos on the Quest devices? Do I have to modify the native plugin?
