VideoTexture to Skybox?

[JeromeCHA]

I am trying to put a videoTexture to a skybox to have a 360 panorama video.

I followed VideoMaterial code source, and I was able to get exoplayer's texture and map it into a node.

However, I would like to display it as a skybox.

When I tried, by doing

                   val texture = VideoTexture.Builder()
                        .stream(stream)
                        .build(engine)

                    skybox = Skybox.Builder()
                        .environment(texture)
                        .build(engine)

I got the following error.

Filament                 E  Panic
                            in build:82
                            reason: environment maps must be a cubemap

Is there any way to get a cubemap from a videoTexture?
I tried with IBLPrefilter, but it doesn't work because VideoTexture is not a 2D texture. It is quite confusing even looking at the code.

sceneview-android/sceneview_2_0_0/src/main/java/io/github/sceneview/utils/IBLPrefilter.kt

Lines 32 to 48 in ad52375

	fun equirectangularToCubemap(equirect: Texture): Texture =
	equirectangularToCubemap.run(equirect)

Can someone please tell me what is the best way to do it?
