Problem

We plan to launch a new computer case with a 4K touch screen. We intended to showcase product features in 3D, but we tried a lot of instructional video texture tutorials and none of them worked properly in iOS 16.

iOS has many limit. I tried many times and sorted out the key points

• Using native html video outside of Three.js canvus
• Video must be mutte
• Disable auto play
• playsInline
• crossOrigin="anonymous"
• display none
• Video url must have full domain name with https

Using native html video outside of Three.js canvus

<Canvas>
...
</Canvas>
  <video
                        id="video"
                        playsInline
                        webkit-playsinline
                        muted
                        loop
                        style={{ display: 'none' }}
                        crossOrigin="anonymous"
                    >
                        <source src={videoUrl} type="video/mp4"></source>
                    </video>

Using Video Texture

import * as THREE from 'three';
import { GLTF } from 'three-stdlib';

type GLTFResult = GLTF & {
    nodes: {
        Cube: THREE.Mesh;
    };
    materials: {
        ['default']: THREE.MeshStandardMaterial;
    };
};

type ContextType = Record<string, React.ForwardRefExoticComponent<JSX.IntrinsicElements['mesh']>>;

export function VideoCanvas(props: JSX.IntrinsicElements['group']) {
    const { nodes, materials } = useGLTF(SHOW_ROOM_3D_URL + 'y70/video-canvas.glb') as GLTFResult;

    const {
        videoPlay: { isPlaying },
    } = useContext(CanvasContext);

    const touchScreenImgTexture = useTexture(SHOW_ROOM_3D_URL + 'y70/hyte-y70-case-touch-screen.png');
    const video = document.getElementById('video');

    const VideoMaterial = () => {
        if (video instanceof HTMLVideoElement) {
            const texture = new THREE.VideoTexture(video);

            texture.wrapS = THREE.RepeatWrapping;
            texture.wrapT = THREE.RepeatWrapping;
            texture.repeat.x = -1; //  -1 為鏡像翻轉
            texture.flipY = true;

            texture.repeat.set(1, 1);

            return (
                <mesh
                    scale={[2.8, 2, 1]}
                    rotation={[0, -Math.PI / 4, 0]}
                    geometry={nodes.Cube.geometry}

                    castShadow
                >
                    <planeGeometry />
                    {isPlaying && <meshBasicMaterial side={THREE.FrontSide} map={texture} toneMapped={false} />}
                    {!isPlaying && (
                        <meshBasicMaterial side={THREE.FrontSide} map={touchScreenImgTexture} toneMapped={false} />
                    )}
                </mesh>
            );
        }
        return <></>;
    };

    return (
        <group {...props} dispose={null}>
            <mesh
                geometry={nodes.Cube.geometry}
                material={materials.default}
                position={[-0.114, 0.253, 0.1925]}
                rotation={[0, Math.PI / 4, 0]}

                <VideoMaterial />
            </mesh>
        </group>
    );
}

useGLTF.preload(SHOW_ROOM_3D_URL + 'y70/video-canvas.glb');

Result

it's work for us. Hope it can help you too.
