We are using HISPlayer for Unity and Unreal Engine projects, to stream 3D 360, 8K videos on Meta Quest and other devices.
Initially, we had a lot of issues with the Unity player mentioned above. So we made a big benchmarking. We can say that HISPlayer is only Player providing stable video playback with the highest FPS in Vulkan Android apps. After testing and using it for so many hours, we definitely recommend it.
P.S. if you need streaming, it supports HLS and DASH videos.
