I'm building a Unity app that plays back 180 degree top/bottom stereoscopic 1920x3840 VR 60fpsvideo.
I can get very smooth playback on Go and Quest with H.265 @ 31Mbs with Unity's default Video Player.
I can't however get smooth playback on PC...
I'm attempting with the following codecs:
H264 @ 75Mbs, 50Mbs, 25Mbs, 12Mbs
H265 @ 31Mbs
I've tried the following players:
- Unity Video Player
- Unversal Media Player
With these players I seem unable to determine if any hardware acceleration is taking place.
The PC I'm testing on has a RTX 2080 and an i5 8500 running Windows 10.
I'm testing with an Oculus Rift S and Quest via link.
All videos are somewhat choppy, even the lower quality ones.
To get the playback to be smooth on the android devices, I had to set the devices refresh rate to 60 fps, the same as the videos FPS to eliminate any stuttering. It seems however you cannot change the fps on Rift, Rift S or Quest Link which run at 90, 80 and 72 fps respectively.
Is there any way to sync up the refresh rate with the fps on PC or is there something else I'm supposed to be doing for smooth playback? How does other software achieve it?
