Abstract
A file-processing subsystem exports functionality to an application to select optional preloading of a file by the file-processing subsystem. The application optionally selects preloading of the file and the file-processing subsystem preloads the file in accordance with the optional selection by the application. In one embodiment, video frames may be preloaded from a video file, where preloading may include decompressing the video frames. In addition, the preloaded video frames may be retained in memory for repeated display.
