Description

Screenshot method, system, device and storage medium for live shared video

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 26, 2024, with application number 202410118399.7, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of video live broadcast technology, and in particular to a method, system, device, and storage medium for capturing screenshots of live shared videos. Background Art

[0003] Currently, in live video streaming scenarios, the host can combine video resources (such as film and television images) with the host's own images and send them to the live streaming platform. The live streaming platform then sends them to the user end to achieve video sharing. To reduce the resource usage of the live streaming platform, the host can directly search and play video resources from the video sharing platform on the host end. The video stream is transmitted from the video sharing platform to the viewer end. The live streaming platform is only responsible for synchronization progress and does not need to store or transmit video resources. This model can save the bandwidth and storage resources of the live streaming platform, while also increasing the richness and interactivity of the live streaming content.

[0004] However, since the shared video resources are not transmitted through the live broadcast platform, the live broadcast platform cannot obtain the video content of the video resources, and cannot review and filter the video content, which may cause some illegal video content to appear in the live broadcast, causing adverse effects.

[0027] In order to make the purpose, technical solutions and advantages of the present application clearer, the specific embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. It is understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. It should also be noted that, for ease of description, only parts related to the present application, not all of the contents, are shown in the accompanying drawings. Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow charts describe each operation (or step) as a sequential process, many of the operations therein can be implemented in parallel, concurrently or simultaneously. In addition, the order of the operations can be rearranged. The process can be terminated when its operation is completed, but can also have additional steps not included in the accompanying drawings. The process can correspond to a method, function, procedure, subroutine, subprogram, etc.

[0028] The screenshot method of live shared videos provided in this application is intended to obtain live shared videos from video sharing platforms through video identifiers, and then extract frames according to the real-time playback progress of the live shared videos to obtain video screenshots, so as to realize the video content acquisition and review of shared videos transmitted by third-party video sharing platforms to avoid the occurrence of illegal content.

[0029] In the relevant video sharing live broadcast scenario, the anchor will merge the video resources (such as film and television pictures) and the anchor's picture and send them to the live broadcast platform, which will then send them to the user. With the development of video sharing platforms and live broadcast platforms, a new video sharing live broadcast mode has emerged. In this mode, the anchor can search and play the video resources of the video sharing platform directly on the anchor terminal and watch them synchronously with the audience. The video stream is transmitted by the video sharing platform, and the live broadcast platform is only responsible for synchronizing the progress. The advantage of this mode is that it saves the bandwidth and storage resources of the live broadcast platform, while also increasing the richness and interactivity of the live broadcast content. However, this mode also brings a problem, that is, the supervision of live broadcast content. Since the shared video stream does not pass through the live broadcast platform, the live broadcast platform cannot review and filter the video content, which may cause some illegal video content to appear in the live broadcast. Based on this, the screenshot method of the live shared video of this application is provided to solve the technical problem that the shared video transmitted through the video sharing platform cannot obtain the video content.

[0030] Example:

[0031] FIG1 is a flowchart of a method for capturing live and shared video provided in an embodiment of the present application. The method for capturing live and shared video provided in this embodiment can be executed by a device for capturing live and shared video. The device can be implemented in software and / or hardware. The device can be composed of two or more physical entities, or a single physical entity. Generally speaking, the device for capturing live and shared video can be a processing device such as a live server.

[0032] The following description will be made by taking the live broadcast server as the main body of the method for executing the screenshot of the live broadcast shared video as an example. Referring to Figure 1, the screenshot method of the live broadcast shared video specifically includes:

[0033] S110: Obtain the video ID and playback start progress of the current live shared video, and send the live shared video to the host terminal and the audience terminal through the video sharing platform for synchronous playback.

[0034] In the process of taking screenshots of live shared videos, this application obtains the video identifier and playback start progress of the current live shared video, so as to subsequently pull the live shared video stream from the video sharing platform for screenshots. Referring to Figure 2, in a live broadcast scenario, when the host needs to share the corresponding video with the audience, he can choose to turn on video sharing live broadcast on the live broadcast client (i.e., the host end), and then search and select the video to watch on the video sharing platform in the host end, and define the currently selected video as the live shared video. The live shared video is transmitted to the host end through the video sharing platform. At the same time, the host end obtains the video identifier (i.e., video ID) of the live shared video and determines the playback start progress of the live shared video. Generally speaking, if the host does not operate the playback progress of the live shared video, the playback start progress defaults to the initial moment of the live shared video. Otherwise, if the host operates the playback progress of the live shared video, the playback progress position selected by the host is used as the playback start progress. The host end will send the video identifier and playback start progress to the live backend service platform. The video identifier and playback start progress are synchronized to the audience end through the live backend service platform. Based on the video ID, the viewer can pull the corresponding live shared video from the video sharing platform for playback and select the video playback position according to the playback start progress to ensure synchronization with the host's video playback progress, achieving the effect of synchronized live shared video. In addition, the host can also synchronize video-related information such as video duration and playback status to the viewer through the live broadcast backend service. Based on the actual synchronized playback requirements of the shared video, the viewer's required synchronization information can be adaptively configured.

[0035] Furthermore, in order to avoid the occurrence of illegal content during the playback of live shared videos, the live broadcast server also needs to synchronize the video identifier and playback start progress of the current live shared video from the live broadcast backend service, so as to subsequently pull the live shared video and perform screenshot operations based on the above video identifier and playback start progress. Similarly, according to actual needs, the live broadcast server can also synchronize the above video related information such as video duration and playback status. It should be noted that the live broadcast backend service, live broadcast screenshot and live broadcast review operations of this application can be integrated into the live broadcast server for execution, or they can be executed separately by different platforms. The live broadcast server only needs to obtain the video identifier and playback start progress provided by the live broadcast backend service.

[0036] S120: Obtain a live shared video from a video sharing platform based on the video identifier.

[0037] Furthermore, by obtaining the video ID, the corresponding live broadcast shared video can be pulled from the video sharing platform for playback. The video sharing platform can be of different types, providing video streams for the host to share and play during the live broadcast. Each video contains a unique video ID for easy identification. Based on the video ID, the live broadcast server can access the corresponding video sharing platform and obtain the live broadcast shared video corresponding to the video ID to perform a screenshot operation on the live broadcast shared video.

[0038] S130: determining the real-time playback progress according to the playback start progress, extracting frames from the live shared video after the real-time playback progress to obtain video screenshots, and performing video content review of the live shared video based on the video screenshots.

[0039] Based on the acquired live shared video, by determining the real-time playback progress of the live shared video on the live broadcast side, the video content can be reviewed by taking video screenshots starting from the playback position after the real-time playback progress. It is understandable that there is a time difference between the start of the live shared video playback on the host side and the start of the screenshot operation on the live broadcast server. The purpose of reviewing video screenshots is to avoid video content violations and to filter out illegal content in a timely manner. Therefore, it is necessary to determine the real-time playback progress of the live shared video and then obtain video screenshots from the playback position after the real-time playback progress.

[0040] Exemplarily, the live broadcast server obtains video screenshots through the video frame extraction module. When starting to take screenshots, a frame extraction request is sent to the video frame extraction module. After receiving the frame extraction request, the video frame extraction module calculates the real-time playback progress (i.e., the playback start progress plus the time difference) based on the playback start progress and the time difference from the start of playing the live shared video to the current moment on the live broadcast end, and performs frame extraction and screenshot conversion starting from the current real-time playback progress. By adjusting and speeding up the video stream pulling speed, a pre-screenshot can be taken 1 second / 3 seconds / 5 seconds after the current real-time playback progress, and the progress of the stream pulling and frame extraction and screenshot conversion is kept ahead of the real-time playback progress. In this way, under the premise of ensuring the real-time and interactivity of the live broadcast, the live video content can be screenshoted in advance and submitted to the review system for review.

[0041] Further, referring to FIG3 , after extracting frames from the live shared video to obtain video screenshots after the real-time playback progress, the method further includes:

[0042] S1301: Store the video screenshot in the file system and obtain a resource locator corresponding to the video screenshot in the file system;

[0043] S1302: Send the video identifier, resource locator, play start progress and real-time play progress to the live broadcast review system so as to conduct video content review of the live broadcast shared video through the live broadcast review system.

[0044] The video screenshot obtained from the video frame extraction module is sent to the screenshot processing module to be uploaded to the file system for storage, and the resource locator returned by the file system is received. The resource locator indicates the storage location of the video screenshot in the file system. After receiving the resource locator of the screenshot, the video identifier, resource locator, playback start progress and real-time playback progress are sent to the live broadcast review system together. In addition, the live broadcast room attribute information (live broadcast room type, such as single-person, multi-person, voice, video and other live broadcast rooms, multiple attributes can exist at the same time), video playback status and other related information can also be sent to the live broadcast review system. The live broadcast review system receives the above information, uses the resource locator to obtain the corresponding video screenshot from the file system, and conducts a video screenshot review based on the above information to determine whether the video content violates the rules. If a violation occurs, it is necessary to shut down the dissemination of the live broadcast shared video in time to prevent the audience from receiving the illegal content, thereby ensuring the transmission security of the live broadcast shared video and optimizing the live broadcast operation and maintenance effect.

[0045] This allows for effective screenshots and review of live content from cross-platform video sharing broadcasts. This involves using a video frame crawler to extract the selected video, converting it into a screenshot, and then uploading it to file storage and submitting it to the review system for review, thereby meeting the requirements for live content supervision. It should be noted that different countries and regions have different review standards for live shared video content, and video sharing platforms and live broadcast platforms may belong to different countries or regions. In this case, even if the video sharing platform reviews the video content as compliant, it may not meet the review standards of the live broadcast platform. Therefore, it is necessary to conduct a compliance review of live shared videos shared by third-party video sharing platforms to avoid content that does not meet the review standards of the live broadcast platform.

[0046] Optionally, after obtaining the video identifier and playback start progress of the current live shared video, the method further includes:

[0047] When it is detected that the host adjusts the playback progress of the live shared video, the playback start progress is updated synchronously.

[0048] When the host adjusts the playback progress of a shared video on their end, they notify the live streaming backend service of the playback status and the latest progress. The live streaming backend service then synchronizes this information with the audience in the live streaming room and the live streaming screenshot system. The audience resumes playback from the latest progress, and the live streaming screenshot system notifies the video frame extraction module to adjust the video frame extraction and screenshot position, continuing the frame extraction and screenshot conversion from the new position.

[0049] Understandably, when a host adjusts the video playback progress during a live broadcast, the skipped video content will not be played in the live broadcast room and therefore does not require review. Through the video progress synchronization mechanism, the host will send the new progress starting point to the live broadcast backend service. The live broadcast backend service adjusts the working position of the screenshot system based on the new progress starting point, thereby achieving synchronization of live broadcast screenshots.

[0050] Optionally, after extracting frames from the live shared video after the real-time playback progress to obtain a video screenshot, the method further includes:

[0051] When it is detected that the host has paused the live broadcast shared video, or the number of online viewers in the corresponding live broadcast room of the host is lower than the set number, the frame extraction of the live broadcast shared video is stopped.

[0052] When the anchor pauses the shared video playback on the anchor side, or the live broadcast backend server calculates that the number of viewers in the live broadcast room is lower than the set number, such as the number of viewers in the live broadcast room is 0. The live broadcast backend server synchronizes information to the live broadcast screenshot system, and the live broadcast screenshot system notifies the video frame extraction module to stop extracting frames and converting screenshots. Since the video content will not be disseminated, there is no need for screenshot review, in order to reduce the resource consumption of the live broadcast platform related services. Until the anchor continues to play the shared video or the number of viewers in the live broadcast room is not 0, the live broadcast screenshot will be reopened. In this way, by notifying the screenshot system through the backend service to stop crawling and converting screenshots for review, the efficiency of live broadcast review can be improved and the resource consumption of the live broadcast platform related services can be reduced.

[0053] In addition, referring to FIG4 , after extracting frames from the live shared video to obtain video screenshots after the real-time playback progress, the method further includes:

[0054] S1303: Obtain the host's live broadcast room attribute information and / or the number of online viewers, and determine the video screenshot resolution based on the live broadcast room attribute information and / or the number of online viewers;

[0055] S1304: Convert the resolution of the video screenshot according to the video screenshot resolution, and save the converted video screenshot.

[0056] During the live broadcast process, the live broadcast backend service synchronizes the live broadcast room attribute information and the number of online viewers in real time to the live broadcast screenshot system. Among them, the live broadcast room attribute information identifies the live broadcast type of the live broadcast room, such as single-person, multi-person, voice, video, etc. According to different live broadcast room attributes, different video screenshot resolutions can be configured. Similarly, for different numbers of online people, the video screenshot resolution can also be adaptively adjusted. Generally speaking, the more people online, the closer the video screenshot resolution is to the original image. Conversely, if there are fewer people, the video screenshot resolution can be adaptively lowered to reduce the video screenshot's occupancy of the server hard disk storage space. It is understandable that in the case where the live broadcast shared video has a smaller dissemination range, the server hard disk storage space occupied by the video screenshot can be adaptively reduced.

[0057] The video screenshot resolution is determined based on the live broadcast room attribute information and / or the number of online viewers, including:

[0058] The video screenshot resolution corresponding to the resolution level is selected according to the live broadcast room attribute information and / or the number of online viewers. The resolution level corresponds to different ranges of online viewers and / or different live broadcast room attribute settings.

[0059] Exemplarily, the screenshot processing module classifies the live broadcast room screenshots into three grades: large, medium, and small, according to a preset threshold value, and performs proportional scaling when the video frame extraction module extracts the frame data and converts it into a screenshot. Taking the video screenshot with a resolution of 1920x1080 as an example, when the number of viewers in the live broadcast room is between 1 and 5, the screenshot is scaled to 854x480, when the number of viewers is between 5 and 20, it is scaled to 1280x720, and when the number of viewers is greater than 20, the original size is maintained. In this way, the space occupied by file storage can be reduced while ensuring the availability of screenshots. Similarly, for different live broadcast room attributes, corresponding resolution gears can also be configured for resolution conversion. According to actual needs, different live broadcast room attributes can also set different optional gear ranges, and then the video resolution gear can be selected from the optional gears based on the actual number of online viewers.

[0060] In addition, a calculation formula can be set according to different live broadcast room attribute information, and then the corresponding video resolution can be calculated according to the number of online viewers and the corresponding calculation formula to perform resolution conversion for video screenshots.

[0061] In this way, by dividing the video screenshots to be converted into three resolutions: large, medium and small, the back-end server synchronizes the live broadcast room attribute information and / or the number of online viewers to the screenshot system, and dynamically converts them into one of the resolutions based on the live broadcast room attribute information and / or the number of online viewers. While ensuring the availability of the screenshots, the space occupied by file storage is effectively reduced and storage costs are reduced.

[0062] In addition, referring to FIG5 , after the video content review of the live shared video based on the video screenshot is performed, the following steps are also included:

[0063] S1305: If it is determined that the live shared video is played continuously and completely, obtain the video content review result of the live shared video;

[0064] S1306. If the video content review result shows no violation, the live shared video is placed in the video white library for use in video screenshots and skipping decisions for video content review.

[0065] After the shared video is played, when the live broadcast review system receives a screenshot of the video playback status, it determines whether the screenshots are continuous from the beginning to the end of the video, and whether any screenshots hit high-risk (i.e., violations). If the video screenshots are continuous and complete and do not hit high-risk, the video will be recorded in the video white library.

[0066] By establishing a video white library to record videos that have been fully reviewed, the resource consumption of repeated screenshot review can be reduced. Afterwards, when the live screenshot system receives a live screenshot request, it will first query the live review system to see if it is in the video white library (recording videos that have been fully reviewed and have no high-risk screenshots) based on the video ID in the request. If the video is recorded in the video white library, there is no need to take a live screenshot, so as to reduce repeated screenshots and reduce the consumption of file storage space and review resources; if it is not in the video white library, the video ID and the video playback start progress will be notified to the video frame extraction module, and the video frame extraction module will start to pull the video stream from the video sharing platform, parse the video stream frame and convert it into screenshots. By first querying whether the video is in the video white library, the videos in the video white library no longer need to be crawled and screenshoted by the video frame extraction module for review, thereby avoiding redundant review of video sharing live content.

[0067] As mentioned above, by obtaining the video ID and playback start progress of the current live shared video, the live shared video is sent to the host end and the audience end through the video sharing platform for synchronous playback; based on the video ID, the live shared video is obtained from the video sharing platform; the real-time playback progress is determined according to the playback start progress, and the live shared video is extracted from the real-time playback progress to obtain a video screenshot, so as to review the video content of the live shared video based on the video screenshot. By adopting the above technical means, the live shared video is obtained from the video sharing platform through the video ID, and then the video screenshot is obtained by extracting the frame according to the real-time playback progress of the live shared video. In this way, the video content of the live shared video can be obtained, so that the live broadcast platform can review the shared video transmitted by the video sharing platform, ensure the content compliance of the live shared video, avoid the occurrence of illegal content, and optimize the live broadcast operation and maintenance effect.
