Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and more specifically, to a method, system, device and medium for efficiently displaying effective information in video data. Background Art

[0002] In the current sports lottery app, the lottery draw process is mainly displayed to the public through live broadcast and historical video playback, covering various lottery types such as Super Lotto, Arrangement 3, Arrangement 5, Seven Stars, etc. This mechanism aims to increase the transparency and credibility of the lottery draw process and meet the supervision needs of lottery players and the public for the fairness of the lottery draw.

[0003] However, in actual operation, for users who care about the lottery process, watching the live broadcast is an instant and intuitive way. However, this method requires users to log in to the website at a specific time (i.e. when the lottery live broadcast begins) to watch, and the live broadcast is often interspersed with advertisements and other content that is irrelevant to the actual lottery process, which undoubtedly increases the user's time cost. In addition, if the user is only interested in the lottery results of a specific lottery type, and the lottery order of this lottery type is relatively late, the user has to wait patiently and watch the lottery process of all the previous lottery types, which undoubtedly reduces the viewing efficiency and user experience.

[0004] On the other hand, historical video playback, as another way to watch the lottery process, although it provides time flexibility and allows users to review past lottery records at any time, also faces similar problems as live broadcasts. Users need to manually drag the video progress bar to skip the lottery draws that they are not interested in or are already familiar with. This process is not only cumbersome, but also easy to miss key information during the operation, affecting the continuity and accuracy of viewing.

[0005] In summary, the existing sports lottery APP does not provide a convenient information acquisition solution for the sports lottery draw process, which reduces the efficiency and flexibility of users in obtaining key information. Summary of the invention

[0006] The object of the present invention is to provide a method, system, device and medium for efficiently displaying effective information in video data, thereby solving all or one of the above-mentioned problems existing in the prior art.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment. Example 1

[0026] This embodiment provides an efficient method for displaying effective information in video data, such as Figure 1~Figure 3 As shown, the following steps are included: S100, image capture steps: In this step, the video data to be processed is obtained, the video data to be processed is played, and video screenshots are processed at preset time intervals during the playback process, and finally a number of video screenshots are obtained, as follows: Specifically, the frame grabber FFmpegFrameGrabber (groupId is org.bytedeco, artifactId is javacv) is used to grab video screenshots: Specifically, the continuously captured video screenshots are temporarily saved in jpg format, and the screenshot names are incremented from 1 in chronological order; Specifically, the preset time interval is 1 second, that is, the screenshot frequency is 1 screenshot per second, thereby achieving the effect of not missing the main information frames in the video.

[0027] S200, key screenshot recognition steps: In this step, OCR technology is used to identify key information of several video screenshots, and the video screenshots containing key information are confirmed as key screenshots, as follows: Specifically, since the present application is applied to sports lottery draw videos or live broadcast videos, the aforementioned video screenshots are video screenshots of the sports lottery draw process, and the key information is whether there is a "key ball" in each screenshot; Specifically, taking the Super Lotto as an example, the winning numbers of the Super Lotto are 5 red balls and 2 blue balls, so the "key balls (key information)" are the first balls, the fifth balls, the sixth balls and the seventh balls that appear for the first time; Specifically, taking the game of Arrangement 3 as an example, the winning numbers of Arrangement 3 are 3 red balls, so the "key balls (key information)" are the first and third balls that appear for the first time; Specifically, the OCR technology is used in this step to confirm how many balls are in each screenshot, and finally to confirm a certain video screenshot where the above-mentioned "key ball" appears as the key screenshot.

[0028] S300, GIF synthesis steps: In this step, according to the position of the key screenshots, the captured video screenshots are selectively synthesized to obtain a GIF that can finally contain key information and the video process, as follows: Specifically, the key screenshots containing the "key ball" and the related screenshots between the key screenshots are synthesized into the final GIF animation; Specifically, taking the Super Lotto as an example, when the first screenshot of the first ball is 101.jpg, the first screenshot of the fifth ball is 165.jpg, the first screenshot of the sixth ball is 182.jpg, and the first screenshot of the seventh ball is 192.jpg, the synthesis strategy of the gif animation is as follows: Set 101.jpg, 165.jpg, 182.jpg and 192.jpg as the first to fourth key screenshots respectively; The 63 screenshots from 102.jpg to 164.jpg between 101.jpg and 165.jpg are taken as the first associated screenshots; Take the 9 screenshots from 183.jpg to 191.jpg between 182.jpg and 192.jpg as the second associated screenshots; The first to fourth key screenshots, the first associated screenshots and the second associated screenshots are combined into the final gif animation in the order of the screenshot names.
