Abstract
Systems and methods for processing input media in a computing device are described. In one aspect, a reconstructed frame is cached according to a set of criteria. A request to scrub to a predictive frame of input media is received. Responsive to receiving the request, the predictive frame is decoded starting with the reconstructed frame.
Claims10
A computing device for processing input media, the computing device comprising:
- a processor;
- and
- a physical memory coupled to the processor, the memory comprising computer-program instructions executable by the processor for:
- during playback of a media stream, caching a reconstructed frame according to a plurality of criteria, wherein the reconstructed frame comprises a decoded multimedia content frame, and wherein the criteria for caching the reconstructed frame is based on:
- a detected display device resolution,
- repeated requests for similar frames of input media,
- an indication that a playback application has reverse playback capability, and
- a received request from a playback application to play a given section of content in reverse;
- receiving a request to scrub to a predictive frame of input media, the predictive frame following an intracoded frame within a group of pictures;
- and
- decoding the predictive frame starting with the reconstructed frame.
