Abstract: Techniques are disclosed for video playback decoding surface prediction. For instance, in some embodiments, video content may be parsed for information that can be used to predict what surfaces (e.g., computer graphics shapes to be rendered, as defined by vertices specifying the location and possibly other attributes of the shape) are most likely to be accessed, for example, by a display or a graphics processing unit (GPU) in the near future. In accordance with some embodiments, these surfaces may be pre-loaded, for example, into cache memory or other desired high-bandwidth memory in advance to minimize or otherwise reduce memory access latency. In some cases, these surfaces may be entered in a list that is kept updated with each new input frame, and the surfaces in that list may be kept inside the cache (or other high-bandwidth memory) for future display or GPU access.
