The invention discloses a method and device for analyzing video files. The method comprises: obtaining audio data and video data of a video file; determining at least one mute point of the video file according to the audio data; obtaining a judging segment of the video file according to the video data, and the judging segment includes the host of the video file At least one of a human shot segment, a title segment and a subtitle segment; according to the judging segment, an event segmentation point of the video file is determined in the at least one silent point. The method and device for analyzing a video file in the embodiment of the present invention can accurately determine the event segmentation point of the video file in the at least one silent point by obtaining at least one silent point and a judgment segment of the video file, and determining the event segmentation point of the video file in the at least one silent point according to the judgment segment. The event segmentation point is determined, so that the event segmentation of the video file can be accurately performed, and thus the efficiency and accuracy of video cataloging can be improved.
Description
technical field [0001] The invention relates to the field of information technology, in particular to a method and device for analyzing video files in the field of information technology. Background technique [0002] With the rapid development of network technology and information technology, a large amount of information and information are pouring into our sight. Images, audio, video, etc. are expressed in multimedia data, which greatly improves the click-through rate of news. Multimedia data is gradually replacing text and becoming the main carrier of news. Facing massive news videos, people feel the pressure of "information overload". Therefore, people began to pay attention to how to find the information they are interested in from the massive video data. This demand has prompted the development of technologies such as information retrieval, personalized recommendation, and data mining. [0003] TV news programs are one of the main sources of news videos. The anal...
