Abstract:
A method includes initiating, through an interface of a multimedia application executing on a data processing device, seeking of a desired frame of a video sequence rendered thereon. The desired frame corresponds to a desired point in time. The method also includes causing, through a set of instructions associated with a processor of the data processing device and/or an operating system executing thereon, the processor to decode frames of the video sequence from a closest frame in a temporal past relative to the desired frame following the initiation. Further, the method includes rendering, through the processor and on the interface, frames of the video sequence after a predeterminable threshold time period at a lower frame rate than a frame rate of the video sequence otherwise at least until the desired frame is decoded and rendered when the desired frame is not decoded within the predeterminable threshold time period.
