Abstract

The invention discloses a method and a system for tracing a video file source, which belongs to the field of video monitoring. The method comprises the following steps that when a video file is downloaded, video source information and the video file transmitted from a video monitoring platform are received, and the video source information is written into the end of the video file; when the video file is used, the video source information at the end of the video file is acquired for later service logic use. According to the method and the system, when the file is acquired from the video monitoring platform, the source information is added to the video file, when the video is used, the source information is extracted from the video file, geographic space and time information is provided for users to analyze the video, the purpose that the source information of the video is constantly automatically recoded in the video dispatching and transfer process is achieved, and the users do not need to artificially judge and maintain the video source information each time when the video file is used.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a method and system for tracing the source of video files. Background technique [0002] With the popularity of video surveillance platforms in the field of security, video surveillance platforms are playing an increasingly important role in the field of public security. When the police investigate a case, they need to copy and edit video clips from various large video surveillance platforms or small surveillance systems as evidence in the case. When the police use video clues to analyze the case, the time information and geospatial information of the video are very important. Information. Existing monitoring systems mainly rely on video visual watermark information to illustrate the source information of the video, that is, display the recording time of the video and the name of the camera (usually named after the geographical location, such as the intersection of Wulin Road and...
