Problems solved by technology
[0002] After 5G is officially commercialized, it is announced that a new era of 5G is coming. With the impact of 5G on the Internet and mobile platforms, whether traditional live video broadcasting can no longer satisfy most audiences and commercial purposes
There is also an image processing method on the market, which collects images through an image acquisition device; puts the collected image input into the queue, and uses a small algorithm to judge whether the image meets the requirements, and if it is satisfied, the image is saved to form a video for people to watch later. In the short term, this method can be used to synthesize video to form a slow live broadcast, but this method has certain defects. The number of post-imaging pictures will increase, the quality of the picture will increase, and the corresponding video synthesis time will be greatly increased, which is not conducive to the use of slow live broadcast.

Embodiment Construction
[0025] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.
[0026] The core difficulty of slow live broadcast technology is how to draw frames and how to discard frames in an orderly manner when there are more images in the later stage. The most direct way to solve the above difficulties is to use an algorithm, and use the frame extraction algorithm to add long-trained model packages to achieve different scenarios using different model packages. The imaging images are divided into 1 to 6 levels. With the increase of imaging images, high-level imaging images can be discarded in an orderly manner to achieve a streamlined and classic effect. In short, in the ecological environment of slow live broadcast, th...

The invention discloses a method and system for constructing a slow live broadcast processing based on a live stream frame extraction algorithm. The slow live broadcast server obtains a video source by pulling the live stream, extracts video frames within a planned time period, and uses the change rate of the video frames as a basis , to judge whether the video frame is valid or not, and open the algorithm model for screening. During the screening, the imaging images will be divided into 1-6 grades according to the model, and the imaging images with higher grades are less important than those with lower grades. After screening, the data will be Save locally. At the same time, the slow live server starts the thread service, performs video pre-synthesis, and obtains the number and time difference of the imaged images saved locally. During a predetermined period of time, if the number of images exceeds a certain threshold, the high-level imaging images will be discarded in an orderly manner. Post composite temporary video. The client requests the slow live broadcast server to watch the slow live broadcast, and can choose to watch it in the form of video recording or in real-time streaming mode.
Description
technical field [0001] The invention relates to the technical field of mobile internet, and in particular, to a method and system for constructing slow live broadcast processing based on a live stream frame extraction algorithm. Background technique [0002] After the official commercial use of 5G, it is announced that a new era of 5G is coming. With the impact of 5G on the Internet and mobile platforms, whether traditional live video broadcasts can no longer satisfy most audiences and commercial purposes. The slow live broadcast ecology was born, and this live broadcast ecology formed a sharp contrast with the regular live broadcast. [0003] For most of the small video applications on the market at present, slow-motion video clips such as Douyin, clipping, etc. have been launched successively, using video clips to edit photos or directly selecting photos to synthesize dynamic and slow-motion videos later, in layman’s terms. There is also an image processing method on the ...
