Video commenting method and video player

Abstract

The embodiment of the invention discloses a video commenting method. The method comprises the following steps of: receiving a comment adding command; calling a comment adding tool according to the comment adding command; adding comment information for a video by using the comment adding tool, wherein the comment information comprises the motion trail of an object in the video; a method for adding the motion trail of a target comprises the following steps of: marking the target in the video by using a graphic shape, acquiring the screen coordinate of the target at a moment when the video is played and the screen coordinate of the target from a next moment when the video is played to next N moments, wherein N is a natural number of more than 1; and acquiring the motion trail of the target which is formed by the movement of the screen coordinate at different moments and consists of the graphic shape marking the target according to a video playing sequence. The embodiment of the invention also provides a video player. In the embodiment of the invention, independence of comment data and video data is realized and the motion trail of the target in the video is marked in the video without compression.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a video annotation method and a video player. Background technique [0002] At present, there are some software tools that can annotate text and image information on electronic devices, such as Word office software that can annotate text documents, PDF readers, etc. These tools can read text In the document, select a certain text in the document, and add comments and notes to the text. However, in the field of video, methods for marking and annotating video content are still lacking. [0003] The methods for marking and annotating video content in the prior art are generally as follows: using video synthesis technology, through relatively professional-level video editing software, and using video synthesis, the annotations (text, graphics, etc.) and video to video content are suppressed into Together, generate a new video data; or in the home video recorder scene, simply a...

AI Technical Summary

Problems solved by technology

[0005] Using video synthesis technology to superimpose the annotation content and video together destroys the original video data, which is not conducive to the reuse of the video, and cannot extract the annotation content, and cannot perform separate editing, time positioning and keyword retrieval on the annotation content; Its scheme of simply associating the text content with the time coordinates of the video cannot record the continuous events in the video, and cannot identify the moving target in the video

[0006] Therefore, the existing video annotation technology cannot mark the moving target in the video without using video synthesis technology.
