Abstract
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.
