当 VideoPlayer.renderMode 设置为 Video.VideoTarget.RenderTexture 时,要在其中绘制资源的 RenderTexture。
如果 RenderTexture 是 TextureDimension.Tex2D ,视频帧将直接绘制到此目标中。为了获得最佳性能,RenderTexture.width 和 RenderTexture.height 应该与视频媒体的相应属性完全匹配。
如果 RenderTexture 是 TextureDimension.Cube,视频帧将被解释为基于视频的宽高比、采用 4 种支持布局(水平或垂直交叉或条状布局)之一的立方体贴图。视频帧的立方体贴图面将绘制到 RenderTexture 的 6 个面。对于一对一像素映射,RenderTexture.width 和 RenderTexture.height 应该与视频媒体的立方体贴图中包含的各个面的大小相匹配(例如,对于一个 2048x1536 水平交叉立方体贴图视频,RenderTexture 立方体大小应设置为 512x512)。
