Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0031] The method of marking the video can also be superimposed on the code stream in the form of a watermark to user information, and the watermark of the code stream can be extracted afterwards, so as to judge the video leaker. The method of superimposing user information into the code stream in the form of watermark will not cause loss of user information due to transcoding. However, the method of superimposing user information into the code st...

Abstract

The present application provides a video marking method, a video source tracing method, a video processing device and a storage medium. The video tagging method includes: obtaining a target video, wherein the target video includes a plurality of video clips; obtaining value information of each video clip, and obtaining the video clip with the highest value; when the user downloads the target video, obtaining user information, and according to User information generates watermark data; superimpose the watermark data into the most valuable video clips. The video marking method of the present application can superimpose the watermark data corresponding to the user information on the most valuable video segment, so that the watermark data will not be lost due to video clipping.

Description

technical field [0001] The present application relates to the technical field of video surveillance and recording protection, in particular to a video marking method, a video source tracing method, a video processing device and a storage medium. Background technique [0002] With the popularization of video surveillance applications, a large amount of video data related to user privacy or security is generated, and these video data are not expected to be seen by irrelevant people. However, sometimes after some users who have the right to view the video download the video, it may spread to those who do not have the right to watch it, resulting in the accidental leakage of the video content. If you want to find out who leaked the video, you must leave it in the video mark. [0003] In the prior art, the user information of the authorized user is generally recorded in the unused field of the frame header of the video code stream, and the user information of the downloaded vide...
