public RenderTexture targetTexture { get; set; }

If the RenderTexture is of TextureDimension.Tex2D the video frames will be drawn directly into this target. For optimal performance, _width and _height should match those of the video media exactly.

If the RenderTexture is of TextureDimension.Cube the video frames will be interpreted as a cubemap in one of the 4 supported layouts (horizontal or vertical orientation of a cross or strip layout) based on video aspect ratio. The cubemap faces of the video frame are drawn to the 6 faces of the RenderTexture. For a one-to-one pixel mapping, _width and _height should match the size of the individual faces contained within the video media's cubemap (eg. for a 2048x1536 horizontal cross cubemap video, the RenderTexture cube size should be set to 512x512).
