Problems solved by technology

Therefore, it is easy to intercept some meaningless video clips only by using the current video interception technology, or it is meaningful, but it cannot help users determine video quality, subtitles, sound and other information clips. Such video clips are not helpful to users. Wasted hard drive and bandwidth for storing video clips

specific Embodiment approach

[0020] In the embodiment of the present invention, a plurality of video file pictures within a period of time are intercepted from the video file, and the average rate of change of the colors of the multiple pictures is calculated. video file.

[0021] Referring to Fig. 1, the method of the embodiment of the present invention includes the following steps:

[0022] Step 101: Intercept at least two pictures within a period of time from the video file.

[0023] Video pictures can be intercepted forward or backward from any point in time of the video file. Preferably, the interception can be started from any time point in the middle time period of the video file.

[0024] Step 102: Calculate the average change rate of the colors of the at least two pictures.

[0025] The specific implementation process of calculating the average rate of change is: group the intercepted pictures, each group has at least two pictures, then calculate the rate of change of the color of each group o...

Abstract

The invention discloses a method and device for multimedia video interception, which is used as the method and device for automatically identifying the high quality video fragment in multimedia video files. The method in the invention comprises the following steps: intercepting at least two pictures within a period of time from the video files, then computing the average rate of change in color of the two pictures, and intercepting the video files within a period of time when the average rate of change is larger than or equal to the predetermined value.

Description

technical field [0001] The invention relates to the field of multimedia video, in particular to a method and device suitable for intercepting multimedia video. Background technique [0002] With the development of multimedia technology, many kinds of videos appear on the Internet. Most videos, such as movies, are provided for users to watch or download online. Many server vendors will provide a video preview before users download. However, with the current video preview interception technology, the interception time is generally very short, such as about 15 seconds, and the interception strategy is to intercept at random or at a fixed time. Since each video resource is different, such as some videos The beginning or end is often completely black, or only the production company information and subtitles of the film appear. The first 10 seconds or even 30 seconds are all black pictures, or even the first 10 minutes of some movies are advertisements that have nothing to do wit...
