Reverse video playback in a data processing device

摘要

A method includes initiating, through an interface of a data processing device, reverse playback of a video file stored in a memory of the data processing device. The method also includes causing, through a set of instructions associated with a processor of the data processing device communicatively coupled to the memory and/or an operating system executing on the data processing device, the processor to read frames corresponding to the video file in a reverse chronological order within a desired timeframe following the initiation of the reverse playback. Further, the method includes decoding, through the processor, each frame corresponding to the reverse chronological order for rendering thereof on the data processing device.

1. A method comprising:
initiating, through an interface of a data processing device, reverse playback of a video file stored in a memory of the data processing device; causing, through at least one of a set of instructions associated with a processor of the data processing device communicatively coupled to the memory and an operating system executing on the data processing device, the processor to read frames corresponding to the video file in a reverse chronological order within a desired timeframe following the initiation of the reverse playback, wherein a timestamp is associated with each one of the frames; decoding, through the processor, each frame corresponding to the reverse chronological order for rendering thereof on the data processing device; and determining a frame rate for the rendering based to maintain a time interval between the timestamps associated with the decoded frames equal to the time interval between the timestamps associated with the frames during a forward playback of the video file.
