Problems solved by technology

The work spent dealing with portions of the source file that the user is not interested in and / or unlikely to care about takes time away from the user's attention to considerations and limits the ability to produce timely previews of the output to the user

Abstract

The invention relates to an opportunistic frame caching. Enhanced, efficient source frame decoding for user previewing is implemented by decoding and caching source frames of an input file that a useris interested in. Source frames for a user preview session are identified and decoded first to enhance user satisfaction with more timely preview segments for review. Additional source frames continue to be decoded on the fly to opportunistically enhance the current preview segment and to be prepared for additional preview segments and / or output file generation.

Description

[0001] The patent application of the present invention is a divisional application of the patent application for invention with the filing date of March 31, 2011, the application number of 201110087439.9, and the title of "opportunistic frame cache". technical field [0002] The present invention relates to various systems and methods of media processing, and more particularly to systems and methods for enabling opportunistic frame caching for media processing. Background technique [0003] Users are able to create or otherwise access various media files, such as video files generated using a video camera or the like, audio files stored on a CD or hard drive of a computing device, and the like. Users typically desire to edit one or more of these media files, also referred to herein as source files. For example, a user may only be interested in a portion of a media file, such as a small segment in a video file that captures a pet splashing, and the user may desire to turn thi...
