the video play only on game mode in unity on system,
I build an apk file on oculus and run the program, the video play canvas as not play video and immediate exit the program in VR oculus
Try different video codecs, not every video plays on every platform.
If the video is under Assets, not StreamingAssets, you can try different settings in the Inspector.
If you aren’t on the latest 2022.3.56f1 I’d suggest updating, more so the lower the patch release version you currently work with.
