Automatic playback of one or more excerpt(s) of a video sequence on a data processing device

摘要

A method includes initiating, through an interface of a data processing device, generation of one or more excerpt(s) of a video sequence associated with a video file stored in a memory of the data processing device. The method also includes automatically reading, through a processor of the data processing device communicatively coupled to the memory, video frames of the video file corresponding to the one or more excerpt(s) and reference video frames thereof in accordance with the initiation through the interface. Further, the method includes decoding, through the processor, the video frames of the video file corresponding to the one or more excerpt(s) and the reference video frames thereof following the automatic reading for rendering thereof on the data processing device.

1. A method comprising:
initiating, through an interface of a data processing device, generation of at least one excerpt of a video sequence associated with a video file stored in a memory of the data processing device; automatically reading, through a processor of the data processing device communicatively coupled to the memory, video frames of the video file corresponding to the at least one excerpt and reference video frames thereof in accordance with the initiation through the interface; and decoding, through the processor, the video frames of the video file corresponding to the at least one excerpt and the reference video frames thereof following the automatic reading for rendering thereof on the data processing device, wherein the decoding of the video frames and the reference video frames further comprises:
decoding, through the processor, each key frame of the video sequence, at least one video frame around the each key frame of the video sequence temporally closest thereto and at least one reference video frame of the at least one video frame around the each key frame;decoding, through the processor, at least one another set of a decoded key frame, at least one video frame around the decoded key frame and at least one reference video frame thereof;skipping decoding other video frames of the video sequence; andcompositing, through the processor, the decoded each key frame, the at least one video frame around the each key frame and the at least one reference video frame thereof with the at least one another set of the decoded key frame, the at least one video frame around the decoded key frame and the at least one reference video frame thereof to generate highlights of the video sequence as the at least one excerpt.
