    • An application program utilizes a decoding sub-system and a three-dimensional (3D) rendering sub-system to apply effects to a video in-place in a document. The program configures pixel shaders for use with a rendering device for applying pixel-level effects to the decoded frames of the video, generates meshes, and pre-renders textures for use in implementing effects. When a request is received to play back the video in-place in the document, a decoding surface and a rendering surface are allocated. The decoding sub-system decodes frames of the video and copies the decoded frames to the decoding surface on one thread. A separate thread copies decoded frames from the decoding surface to a texture and from the texture to the rendering surface. The rendering device utilizes the pixel shaders, meshes, pre-computed textures, and other data to render the frames of the video to a rendering target.
    • 应用程序利用解码子系统和三维(3D)渲染子系统将效果应用于文档中就地的视频。 该程序将像素着色器配置为与渲染设备一起使用,以将像素级效果应用于视频的解码帧,生成网格,并预渲染纹理以用于实现效果。 当接收到在文档中就地再现视频的请求时,分配解码表面和渲染表面。 解码子系统解码视频的帧,并将解码的帧复制到一个线程上的解码表面。 单独的线程将解码帧从解码表面复制到纹理,并从纹理复制到渲染表面。 渲染设备利用像素着色器,网格,预先计算的纹理和其他数据将视频的帧呈现到呈现目标。
