		<h1>[name]</h1>

		<p class="desc">Creates a texture for use with a video.</p>

		<p>
			Note: After the initial use of a texture, the video cannot be changed.
			Instead, call [page:.dispose]() on the texture and instantiate a new one.
		</p>

		<h2>Code Example</h2>

		<code>
		// assuming you have created a HTML video element with id="video"
		const video = document.getElementById( 'video' );
		const texture = new THREE.VideoTexture( video );
		</code>

		<h2>Examples</h2>

		<p>
			[example:webgl_materials_video materials / video]<br />
			[example:webgl_materials_video_webcam materials / video / webcam]<br />
			[example:webgl_video_kinect video / kinect]<br />
			[example:webgl_video_panorama_equirectangular video / panorama / equirectangular]<br />
			[example:webxr_vr_video vr / video]
		</p>

		<h2>Constructor</h2>
		<h3>
			[name]( [param:Video video], [param:Constant mapping], [param:Constant wrapS], 
			[param:Constant wrapT], [param:Constant magFilter], [param:Constant minFilter], 
			[param:Constant format], [param:Constant type], [param:Number anisotropy] )
		</h3>
		<p>
			[page:Video video] -- The video element to use as the texture. <br />

			[page:Constant mapping] -- How the image is applied to the object. An
			object type of [page:Textures THREE.UVMapping]. 
			See [page:Textures mapping constants] for other choices.<br />

			[page:Constant wrapS] -- The default is [page:Textures THREE.ClampToEdgeWrapping]. 
			See [page:Textures wrap mode constants] for
			other choices.<br />

			[page:Constant wrapT] -- The default is [page:Textures THREE.ClampToEdgeWrapping]. 
			See [page:Textures wrap mode constants] for
			other choices.<br />

			[page:Constant magFilter] -- How the texture is sampled when a texel
			covers more than one pixel. The default is [page:Textures THREE.LinearFilter]. 
			See [page:Textures magnification filter constants]
			for other choices.<br />

			[page:Constant minFilter] -- How the texture is sampled when a texel
			covers less than one pixel. The default is [page:Textures THREE.LinearFilter]. 
			See [page:Textures minification filter constants] for
			other choices.<br />

			[page:Constant format] -- The default is [page:Textures THREE.RGBAFormat].
			See [page:Textures format constants] for other choices.<br />

			[page:Constant type] -- Default is [page:Textures THREE.UnsignedByteType].
			See [page:Textures type constants] for other choices.<br />

			[page:Number anisotropy] -- The number of samples taken along the axis
			through the pixel that has the highest density of texels. By default, this
			value is `1`. A higher value gives a less blurry result than a basic mipmap,
			at the cost of more texture samples being used. Use
			[page:WebGLrenderer.getMaxAnisotropy renderer.getMaxAnisotropy]() to find
			the maximum valid anisotropy value for the GPU; this value is usually a
			power of 2.<br /><br />
		</p>

		<h2>Properties</h2>

		<p>See the base [page:Texture Texture] class for common properties.</p>

		<h3>[property:Boolean generateMipmaps]</h3>
		<p>Whether to generate mipmaps. `false` by default.</p>

		<h3>[property:Boolean isVideoTexture]</h3>
		<p>Read-only flag to check if a given object is of type [name].</p>

		<h3>[property:Boolean needsUpdate]</h3>
		<p>
			You will not need to set this manually here as it is handled by the
			[page:VideoTexture.update update]() method.
		</p>

		<h2>Methods</h2>

		<p>See the base [page:Texture Texture] class for common methods.</p>

		<h3>[method:undefined update]()</h3>
		<p>
			This is called automatically and sets [page:VideoTexture.needsUpdate .needsUpdate] 
			to `true` every time a new frame is available.
