how to draw TALTexture on a 3D TSphere ?

[pcplayer]

I have learned the code of TALAndroidVideoPlayer. The player show video by this code:

TCustomCanvasGpu(Canvas).DrawTexture

here, it is a TalTexture.

The Canvas is from TALRectangle.

A 3D TShpere I just know that set a TTextureMaterialSource to it, and load a bitmap into TTextureMaterialSource can show this bitmap on TShpere. But how to show a TalTexture on a TSphere?

Please show some method. Thanks.

I have added some code to test, here is my result:

1. I created a TMyMaterialSource and TMyMaterial( include 2 OpenGL shader code);
2. this code below is worked fine, I can see picture on my phone screen:

ATexture := TALTexture.Create; ATexture.Assign(Image1.Bitmap); Sphere1.MaterialSource := MyMaterialSource1; MyMaterialSource1.Texture := ATexture;
And then I can see my image on my Android phone screen.
So, I know that if I create a TALTexture, I can show it on a 3D control.

But, when I got Texture in TALVideoPlayerSurface.OnFrameAvailable, and then I set it to MyMaterialSource1.Texture, my Sphere1 show nothing, it just changed from black ( no picture) to white.

update:

After I change the color of ViewPort3D to black, and when the video is playing, I can see some white strings on the 3D control.
I have experience that if I have not got patch files the TALVideoPlayerSurface just show black screen with some white strings when video is playing.
So, maybe this is because a 3D control of Delphi need patchs ？
