With continued reference to FIG. 2, a flow 200 of one embodiment of a method of generating a video stream according to the present disclosure is shown. The method for generating a video stream may include the following steps:

Step 210, acquiring a video.

In this step, the executive body of the method for generating a video stream (for example, the server 105 shown in FIG. 1 ) can capture at least one video in real time through the network, and the video can be the content of the network video resource, and the content of the video resource can be derived from various sources. Big video sites, news media sites, Internet TV and so on. The above executive body can take the method of splitting and grabbing when grabbing the content of the video resource, that is, dividing the content of the online video resource according to the content of the video resource to obtain the divided independent video resource, and then grabbing each video resource. A segmented independent video resource. For example, a news video stream in a news media website includes news A, news B, news C, and news D. The above-mentioned executive body can segment the news video stream according to the news content to obtain the segmented independent video news A. , independent video news B, independent video news C, independent video news D, and then the above-mentioned executive body grabs independent video news A, independent video news B, independent video news C, and independent video news D respectively.

In step 220, video preprocessing is performed on the video, and the obtained processed video is stored in a video library.

In this step, after obtaining the video, the above-mentioned execution body may perform video preprocessing on the obtained video to obtain a processed video, wherein the video preprocessing is used to perform video classification and video cropping processing on the video, and obtain a video that meets the requirements. The processed video, the video preprocessing may include classifying the type of the obtained video, and may also include performing video cropping processing on the obtained video. Then the above-mentioned executive body stores the obtained processed video into a video library, where a plurality of processed videos are stored.

In some optional implementations of this embodiment, the above-mentioned execution body may implement video preprocessing on the video based on the following steps:

The first step is to classify the type of the video to obtain the type result corresponding to the video.

In this step, after the above-mentioned execution body obtains the video, it determines the content of the video, and classifies the video according to the content of the video to obtain a type result corresponding to the video, and the type result of the video can be used to identify the type of the video , which can include news, sports, film and television, advertisements, variety shows, etc. Among them, news videos can include news such as radio and television, Internet TV, and self-media; sports videos can include highlights, sports bulletins, and classic shots. and other sports videos; film and television drama videos can include movie previews, TV drama excerpts, highlights, etc. of major video websites; advertising videos can include pre-title ads, radio and television advertisements, TV sales, etc. of major video websites.

As an example, after the above-mentioned execution body obtains the video, it extracts the content of the video, and the extracted video content includes "soccer" and so on. According to the content of the "football" video, it can be determined that the video belongs to a sports video, and then the video is obtained. The corresponding type result is Sports.

The second step is to perform video cropping processing on the video based on the preset duration range corresponding to the type result to obtain the processed video, and store the processed video with the type result set in the video library.

In this step, after obtaining the type result corresponding to the video, the above-mentioned execution body can further obtain the preset duration range corresponding to the type result, wherein each type of result corresponds to a different video duration range, that is, the length of each type of result The video will correspond to a duration threshold range T1-T2. When the duration of the video is less than T1, the video will not be accepted; when the duration of the video is greater than T2, the video will be cropped within the threshold range. The time range corresponding to each type of result can be shown in the following table:

T1 T2 News 10s 3min sports 30s 5min Movies 1min 8min variety show 30s 5min

Then, after obtaining the preset duration range corresponding to the type result, the execution subject performs video trimming processing on the video according to the preset duration range to obtain a processed video that meets the duration range, wherein the video trimming processing may include trimming the video The video clipping process can also be achieved by using appropriate fast-forward to compress the video duration by clipping the content of advertisements, clipping redundant dialogues, clipping repeated pictures, etc. Finally, configure the corresponding type result for the obtained processed video, and store the processed video with the type result in the video library.

As an example, the above-mentioned execution body determines that the type of the video is a sports category. By obtaining from the above table that the corresponding duration range of the sports category is 30s-5min, the obtained video duration is 6 minutes. Analyze the video content in the video to determine whether the video contains advertising content, and if it includes advertising content, then trim the advertising content; determine whether the video contains redundant dialogues, and if it includes redundant dialogues, the redundant dialogues will be processed. Cropping; determine whether the video contains repeated pictures, if it does, the repeated pictures will be cropped; after the video is cropped, the duration of the cropped video is obtained, and it is determined whether the duration of the cropped video is within 30s-5min If it is within 30s-5min, the cropped video will be regarded as the processed video, and the type result of the processed video will be configured: Sports, and the processed video set as sports will be stored in the video library; If it is greater than 5 minutes, the cropped video is further appropriately fast-forwarded to obtain a processed video that meets the duration range.

In this implementation manner, the type result of the video is obtained by classifying the type of the video, and the video is further trimmed according to the type result of the video to obtain the processed video, so that the video can be trimmed to an appropriate duration, and different Different lengths of processed videos corresponding to the types enable each type of video to retain the corresponding content, which improves the flexibility of video preprocessing and improves the diversity of processed videos.

Step 230: Based on the preset video splicing conditions, select multiple processed videos that satisfy the preset video splicing conditions from the video library for video splicing, and generate a video stream corresponding to the preset video splicing conditions.

The preset video splicing conditions are used to filter the processed videos in the video library, that is, multiple processed videos that meet the video splicing conditions can be selected for video splicing. The preset video splicing conditions may include selecting processed videos of the same type, selecting different types of processed videos, selecting processed videos that the user likes, or selecting any processed videos based on different requirements Etc., this application does not specifically limit this.

In this step, the above-mentioned executive body determines the preset video splicing conditions, and then selects from the processed videos included in the video library according to the returned video splicing conditions, and each processed video and the video splicing conditions can be compared respectively, It is judged whether the processed video satisfies the video splicing condition, and a plurality of processed videos that satisfy the preset video splicing condition are selected. Then, video splicing is performed on the selected multiple processed videos, for example, the multiple processed videos are sequentially spliced together to generate a video stream corresponding to a preset video splicing condition.

Optionally, in the process of video splicing, the above-mentioned executive body may also insert advertisement content to generate a video stream including multiple processed videos and advertisement content, thereby improving the diversity of video streams.

Optionally, the length of the video stream can be a change value, and the above-mentioned execution body can select a preset number of processed videos that meet the preset video splicing conditions for video splicing, and the preset number can be adjusted according to the user's viewing duration. For example, when the above-mentioned execution body receives the collected video streams for longer and longer durations, the preset number is adjusted to be larger, for example, from 3 to 6. The above-mentioned executive body can continuously adjust the number of selected processed videos that meet the video splicing conditions, thereby continuously adjusting the duration of the generated video stream, so that users who watch the video stream can always have content that can be viewed.

As an optional implementation, the above-mentioned execution body determines the preset video splicing conditions to include selecting the processed video of the same type of result; and the above-mentioned execution body can select the same type of result from the video library based on the type of result of the processed video in the video library. Video splicing is performed on the multiple processed videos of the result, and a type video stream corresponding to the type result is generated.

Specifically, the above-mentioned execution body obtains the type result of each processed video in the video library, and then sequentially splices multiple processed videos of the same type result to obtain a type video stream, which corresponds to the type result one-to-one. For example, the types of video streams may include news video streams, sports video streams, film and television video streams, variety show video streams, and the like.

As an example, the above-mentioned execution subject selects the processed video A, processed video B, processed video C, and processed video D of the news category in the video library, and then selects the processed video A, processed video B, and processed video C. . After processing, video D is sequentially spliced to obtain a news video stream.

The above-mentioned executive body selects the processed video E, the processed video F, and the processed video G of the sports class in the video library, and then sequentially splices the processed video E, the processed video F, and the processed video G to obtain a sports video. flow.

The above-mentioned executive body selects the processed video H, the processed video I, and the processed video J of the variety show in the video library, and then sequentially splices the processed video H, the processed video I, and the processed video J to obtain a variety show video. flow.

As an optional implementation, the above-mentioned execution body determines the preset video splicing conditions including selecting processed videos of different types of results; and the above-mentioned execution body can select multiple types of results from the video library based on the type results of the processed videos in the video library. Video splicing is performed on multiple processed videos of different types of results to generate arbitrary video streams.

Specifically, the above-mentioned execution body obtains the type result of each processed video in the video library, and then sequentially splices multiple processed videos of different types of results to obtain an arbitrary video stream, which may include multiple types of video streams. The resulting processed video, for example, any video stream may include a news-type processed video, a sports-type processed video, a movie-type processed video, and the like.

As an example, the above-mentioned execution subject selects the processed video A and processed video B of the news category, the processed video C of the sports category, and the processed video D of the film and television category in the video library, and then the processed video A, The processed video B of the news category, the processed video C of the sports category, and the processed video D of the film and television category are sequentially spliced to obtain an arbitrary video stream.

As an optional implementation, the above-mentioned execution body determines the preset video splicing conditions including selecting the processed video corresponding to the user's video preference; and the above-mentioned execution body can obtain the user's video preference; Video splicing is performed on the corresponding multiple processed videos to generate a recommended video stream.

Specifically, the above-mentioned execution body can obtain the user's video preference.
