DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of this application more clear, the present application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] It should be noted that the descriptions of "first", "second", etc. in the embodiments of the present application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0025] In the description of this application, it should be understood that the numerical labels before the steps do not indicate the order in which the steps are executed. They are only used to facilitate the description of this application and to distinguish each step. Therefore, they cannot be understood as limitations on this application.

[0026] First, an explanation of the terms used in this application is provided: Player: A software or hardware device used to play various media content.

[0027] Canvas: An element provided by HTML5 (Hypertext Markup Language) for drawing visual content such as graphics, animations, and games on web pages.

[0028] Video element: refers to a tag or component in a web page that is specifically used to embed and play videos.

[0029] Danmu (bullet screen): Subtitles or images that pop up and move in a predetermined direction when watching a video online. While there's no fixed term for this term in English, it's commonly referred to as comment, danmaku, barrage, bullet screen, or bullet-screen comment. Danmu allows viewers to leave comments or reflections, but unlike typical video sharing websites where comments are displayed in a dedicated area below the video player, these comments appear in real time as sliding subtitles on the video screen, ensuring that all viewers are aware of them. Danmu can be managed through a Danmu system. Some Danmu systems utilize CSS (Cascading Style Sheets) or JavaScript to provide customized Danmu formats, such as allowing them to appear or disappear at specific locations, control their speed, and position. Furthermore, Danmu that appears fixed at the bottom or top of the screen can also serve as subtitles for videos without subtitles.

[0030] Secondly, in order to facilitate those skilled in the art to understand the technical solutions provided by the embodiments of the present application, the relevant technologies are described below: The applicant has learned that the server can perform splicing and expansion processing on the main video, that is, multiple spliced ​​videos and the main video are transcoded and merged into one video, and then the video is sent to the client. The client divides the main video and the spliced ​​video into multiple video elements, and when it is necessary to display the spliced ​​video, the video elements of the spliced ​​video are overlaid on the video elements of the main video. However, this solution of suppressing the spliced ​​video into the main video takes a long time when the video is switched, and the user will experience a serious sense of freeze, which affects the user's viewing experience. In addition, the transcoding cost of the server side of this solution is high, and the spliced ​​video cannot be dynamically adjusted, and the flexibility is poor. Since the video element overlay method has the situation of displaying and hiding video elements, the entire video playback-related experience will be interrupted, such as barrage, thumbnails, etc. will disappear as the video elements are covered, and the drastic changes in the playback screen will make the user's viewing experience feel disconnected.

[0031] To this end, the embodiments of the present application provide a video processing technology solution. In this technology solution, (1) the duration of video switching can be reduced; (2) the computing cost of the server is reduced; (3) the spliced ​​video can be dynamically adjusted with high flexibility; and (4) the changes in the playback screen are reduced to minimize the user's sense of fragmentation. See below for details.

[0032] Finally, for ease of understanding, an exemplary operating environment is provided below.

[0033] like Figure 1 As shown, the environment diagram includes a server 2, a network 6, and a client 4, wherein: The server 2 can be composed of a single or multiple computing devices. These multiple computing devices can include virtualized computing instances. Virtualized computing instances can include virtual machines, such as emulations of computer systems, operating systems, servers, and the like. A computing device can load a virtual machine based on a virtual image and / or other data defining the specific software (e.g., operating system, specialized application, server) used for the emulation. As the demand for different types of processing services changes, different virtual machines can be loaded and / or terminated on one or more computing devices. A hypervisor can be implemented to manage the use of different virtual machines on the same computing device.

[0034] The server 2 can be configured to communicate with the client 6 or the like via a network 4. The network 4 includes various network devices, such as routers, switches, multiplexers, hubs, modems, bridges, repeaters, firewalls, proxy devices, and / or the like. The network 4 can include physical links, such as coaxial cable links, twisted pair cable links, optical fiber links, combinations thereof, or wireless links, such as cellular links, satellite links, Wi-Fi links, and the like.

[0035] The server 2 can provide services such as video transcoding, video confluence, video query, and video delivery, such as providing a video delivery service in response to a video request from a client.

[0036] Client 4 can be an electronic device running an operating system such as Windows, Android™, or iOS, such as a smartphone, tablet, laptop, virtual reality device, gaming device, set-top box, in-car terminal, or smart TV. Based on these operating systems, various applications can be run, such as video playback websites.

[0037] The client 4 can provide / configure a user access page for obtaining videos, etc. from the service platform 2.

[0038] It should be noted that the above devices are exemplary, and the number and type of devices can be adjusted in different scenarios or according to different needs.

[0039] The following describes the technical solutions of the present application through multiple embodiments, using the client or server as the execution body. It should be noted that these embodiments can be implemented in many different forms and should not be interpreted as being limited to the embodiments described here.

[0040] Example 1 Figure 2 The flowchart of the video processing method according to the first embodiment of the present application is schematically shown.

[0041] This video processing method is used in the client, such as Figure 2 As shown, the video processing method may include steps S200 to S202, wherein: Step S200: Obtain a video resource list provided by the server, wherein the video resource list includes multiple resource addresses corresponding to multiple videos.

[0042] Step S202: Based on the multiple resource addresses, obtain video additional information of at least two videos to be played.

[0043] Step S204: combining the additional information of each video according to the video presentation order to obtain resources to be played.

[0044] Step S206: Play the resource to be played, and present the video additional information of the resource to be played to the viewer in the form of a single video.

[0045] The video processing method provided in this embodiment obtains a video resource list provided by a server and, based on multiple resource addresses in the video resource list, obtains video additional information for at least two videos to be played. The video additional information is combined according to the video presentation order to obtain the resources to be played. Therefore, by playing the resources to be played, the video additional information of each video can be displayed in an orderly manner based on a single video. For viewers, the playback of multiple videos appears as a single video, thereby improving the overall viewing experience.

[0046] The following combination Figure 2 , each step in steps S200~S202 and other optional steps are described in detail.

[0047] Step S200 , obtain a video resource list provided by the server, wherein the video resource list includes multiple resource addresses corresponding to multiple videos.

[0048] The client can send a video request to the server to obtain video resources and play them. Based on the video request sent by the client, the server can determine whether the video requested by the client requires video splicing. If the video requested by the client requires video splicing, the server obtains multiple resource addresses to form a video resource list and returns it to the client. The client can play the spliced ​​video based on the video resource list. In some embodiments, the resource address can be a URL pointing to the corresponding video resource. A URL (Uniform Resource Locator) is a standard address used to locate and access resources (such as videos, images, files, etc.) on the Internet.

[0049] Step S202 , based on the multiple resource addresses, obtain video additional information of at least two videos to be played.

[0050] Based on multiple resource addresses, the player can retrieve at least two videos to be played and their corresponding additional video information. Additional video information refers to auxiliary data related to the video, in addition to the audio and video content itself. This information can be used to enhance the user experience or enable additional functionality. Additional video information can include bullet comments and thumbnails. Depending on actual needs, additional video information can also include subtitles, interactive elements (such as like and share buttons), and more.

[0051] Step S204 , according to the video presentation order, the additional information of each video is combined to obtain the resource to be played.

[0052] The video presentation order can be the order in which the corresponding resource addresses of the videos appear in the video resource list. Additional information for each video can be added to the resource to be played in a chronological or logical order. A resource to be played can be composed of multiple videos and their corresponding additional information. The resulting resource to be played can provide users with more video content. Additional information for each video can be uniformly organized and integrated in the resource to be played in a chronological or logical order, so that the resource to be played presents a single video playback effect.

[0053] The following will provide a further exemplary introduction to combining and obtaining resources to be played through more embodiments.

[0054] In an optional embodiment, the video additional information includes bullet screen data. The at least two videos include a main video and one or more spliced ​​videos. Figure 3 As shown, step S204 may include: Step S300, obtaining the barrage data of the main video and the barrage data of each spliced ​​video.

[0055] Step S302: Based on the total duration of the multiple videos, the pop-up time of each barrage data is adjusted according to the video presentation order to obtain multiple barrage data in the resource to be played.

[0056] The main video can be the video requested by the user to be played, and the spliced ​​video is the video associated with the main video. By splicing the spliced ​​video with the main video, the video content of the main video can be expanded to provide more information to the user. Since the resources to be played include multiple videos, in order to make the barrage corresponding to each video display normally, the pop-up time of each barrage data needs to be offset according to the total length of the multiple videos. The pop-up time corresponding to each barrage data needs to be added with the total length of other videos before the corresponding video. For example, the videos to be played include video A, video B and video C, and the video presentation order is ABC. Since there is no other video before video A, the pop-up time of the barrage data of video A does not need to be offset. The pop-up time of the barrage data of video B needs to be added with the length of video A, and the pop-up time of the barrage data of video C needs to be added with the total length of video A and video B.

[0057] In this embodiment, the pop-up time of each bullet screen data is obtained according to the total duration offset of the resource to be played, so as to realize the normal display of the bullet screen of each video, thereby improving the user experience.

[0058] Regarding obtaining the various bullet screen data of the resource to be played. In an optional embodiment, Figure 4 As shown, upload a video list of one or more stitched videos to the server so that the server can perform the following operations: Step S400: Obtain the bullet comment data of each spliced ​​video.

[0059] Step S402: Update the barrage pool of the main video according to the barrage data of the main video and the barrage data of the spliced ​​video; in the barrage pool, the pop-up time of each barrage data is offset according to the total duration of the multiple videos.

[0060] In order to achieve the effect of seamless switching between the barrages of multiple videos as much as possible, the barrage pulling interface can be modified. The modified interface provides the server with a video list of one or more spliced ​​videos, so that the server can return multiple barrage data offset according to the total length of the target video. Since the spliced ​​video only expands the video content of the main video, the spliced ​​video does not have a corresponding barrage pool. In the case that the spliced ​​video does not have a corresponding barrage pool, the barrage corresponding to the spliced ​​video will disappear when the spliced ​​video is played. Therefore, the interface for sending barrages can be modified so that the barrages sent when playing the spliced ​​video can be attributed to the barrage pool of the main video.

[0061] In this embodiment, by updating the barrage data of the spliced ​​video with the barrage pool of the main video, it is possible to effectively prevent the barrage corresponding to the spliced ​​video from disappearing as the playback of the spliced ​​video is completed without being fully displayed during the subsequent playback of the resources to be played, thereby minimizing the drastic changes in the picture that may cause users to feel a sense of playback disconnection.

[0062] In an optional embodiment, the video additional information includes a thumbnail, and the multiple videos include a main video and one or more spliced ​​videos. Figure 5 As shown, step S204 may further include: Step S500: Obtain a thumbnail of the main video and thumbnails of each spliced ​​video.

[0063] Step S502 , based on the total duration of the multiple videos, adjust the corresponding time of each thumbnail on the play progress bar according to the video presentation order to obtain multiple thumbnails in the resource to be played.

[0064] Each thumbnail is displayed as a thumbnail according to the corresponding time mapped on the playback progress bar.

[0065] During video playback, to enhance the fast-forward and preview experience, the player can display thumbnails on the progress bar when the user drags or hovers over it. A thumbnail is a static preview image corresponding to a specific time point in the video and can be generated from a screenshot of the screen at that time point. Each video (including the main video and the stitched video) has a corresponding thumbnail, and each thumbnail represents a specific time point in its corresponding video. After stitching together multiple videos, a main progress bar is created, representing the total duration of the resource to be played. The time points corresponding to each thumbnail are mapped to this main progress bar, and the thumbnail mapped to that time point can then be displayed based on the current playback time point of the resource to be played. For example, if the resource to be played reaches the first minute of the main progress bar, and the resource to be played includes two preceding videos and the currently playing video, and the total duration of these two preceding videos is 40 seconds, the thumbnail corresponding to the 20th second of the currently playing video will be mapped to the first minute of the target video for display. In this embodiment, the binding time of each thumbnail on the playback progress bar is updated according to the total duration of the resource to be played, so as to accurately display the thumbnail corresponding to the time point of the resource to be played.

[0066] Step S202 , the resource to be played is played, and the video additional information of the resource to be played is presented to the viewer in the form of a single video.

[0067] When switching between multiple videos during playback of a resource, a black screen may appear. To minimize this, the next video and its corresponding additional video information can be preloaded before the current video completes playback, so that the resource appears as a single video. Preloading refers to loading a resource or data into memory or cache before it is needed, enabling faster response and reducing latency during actual use. In some embodiments, the next video and its corresponding additional video information can be preloaded before the current video begins playing. Alternatively, the next video and its corresponding additional video information can be preloaded some time before the current video ends, for example, 5 or 10 seconds before the current video ends. In some embodiments, switching between videos and their corresponding additional video information can be performed using IJK, a video player that supports multiple video formats and hardware acceleration. After the current video ends, the preloaded next video and its corresponding additional video information are immediately used to replace it. Because video switching using IJK occurs in milliseconds, there is virtually no lag in video playback, making video switching imperceptible to the user.

[0068] The following will provide a further exemplary introduction to the playback process through more embodiments.

[0069] Regarding sequential playback, such as Figure 6 As shown, in an optional embodiment, the method may include: Step S600: when the current video among the multiple videos is finished playing, extract the last frame of the current video to generate a first canvas image; Step S602: Overlay the first canvas image on the player until the first frame of the next video of the current video is obtained.

[0070] When the current video among multiple videos has finished playing, it is necessary to switch videos. During the switching process, the first canvas image is generated by the last frame and will be overlaid on the player. After the first frame of the next video has been successfully loaded and displayed, the player will remove the first canvas image and play the actual video content of the next video. For example, the player can use the video element (video element) to load and play the current video normally. When the current video is finished playing, the last frame image of the video element is extracted and drawn on the Canvas element to generate a Canvas image (that is, the first canvas image), and the Canvas image is overlaid on the upper layer of the video element. The video element loads the next video. Because the Canvas image is "covering" the video above, the user cannot see that the video screen is changing, and the visual sense remains stable.

[0071] In this embodiment, when the current video among multiple videos is completed, the last frame of the current video is extracted to generate a first canvas image and overlay it on the player to avoid black screen or blank screen as much as possible, thereby achieving seamless switching of videos from the user's perspective.

[0072] Regarding jump play, in an optional embodiment, as Figure 7 As shown, the method may further include: Step S700, in response to a video jump instruction between the multiple videos, extracting a current frame of a current video from the multiple videos to generate a second canvas image; Step S702: Overlay the second canvas image on the player until the target frame of the target video is obtained.

[0073] The target video is the video pointed to by the video jump instruction, the target jump instruction corresponds to a target time point, and the target frame is the frame of the target video pointed to by the target time point.

[0074] The video jump instruction can be triggered by clicking on the progress bar corresponding to the total length of multiple videos, or by clicking on the barrage jump link, which is not limited here. During the jump playback process between multiple videos, video switching is required. During the switching process, the current frame is extracted to generate a second canvas image and it will be overlaid on the player. When the target frame pointed to by the video jump instruction has been successfully loaded and displayed, the player will remove the second canvas image to achieve the jump of the target video. In some embodiments, the second canvas image can also be a Canvas image, which is generated by extracting the current frame image of the video element and drawing it on the Canvas element to generate a Canvas image corresponding to the second canvas.

[0075] In this embodiment, when jumping between multiple videos, the current frame of the current video is extracted to review the second canvas image and overlay it on the player to minimize flickering and freezing during video playback, thereby achieving seamless switching of videos from the user's perspective.

[0076] Regarding jump playback, in an optional embodiment, multiple videos are temporarily stored in a queue, such as Figure 5 As shown, the method further includes: Step S800: In response to a video jump instruction between the multiple videos, a target video to be jumped to is searched from the queue.

[0077] Step S802: Determine the playback progress of the target video according to the jump progress of the video jump instruction.

[0078] Among them, during the video jump process, the display screen of the player is kept at the current screen of the current video at the time of jump and the player is set to a loading state until the target video is obtained, the loading state is canceled and the target video is played.

[0079] Based on the video resource list provided by the server, the client organizes multiple videos into an ordered video playback queue. In default playback mode, the player plays videos sequentially according to this queue. When jumping between multiple videos, the player searches the queue for the target video based on the jump instruction and determines the target video's playback progress based on the jump progress. The loading state is displayed by the player or user interface while waiting for content to load, conveying to the user the message "The system is processing, please wait." For example, if Videos A, B, and C each have a duration of 5 minutes and are played in the order of A, B, and C, the corresponding queue duration is 15 minutes. While playing Video A, a jump instruction is issued, indicating a queue duration of 12 minutes. The jump instruction then finds the corresponding Video C in the queue. Based on the jump instruction's duration (12 minutes) and Video C's duration (5 minutes), the player determines that Video C's playback progress is 2 minutes, and then jumps to the corresponding duration for Video C and plays it.

[0080] In this embodiment, multiple videos are played in a queue, allowing the user to perceive them as a single, coherent video. This allows the user to accurately find and play the target video in the queue based on the progress of the jump, effectively minimizing screen changes and minimizing the user's sense of disconnection during viewing.

[0081] Example 2 The video processing method provided in this embodiment is used in the server, and the technical details can be found above.

[0082] Figure 9 The flowchart of the video processing method according to the second embodiment of the present application is schematically shown.

[0083] like Figure 9 As shown, the video processing method may include steps S900 to S906, wherein: Step S900: receiving a video request sent by a client, wherein the video request includes a video identifier of a primary video.

[0084] Step S902: Determine one or more spliced ​​videos according to the video identifier of the main video.

[0085] Step S904: Generate a video resource list based on the main video and the one or more spliced ​​videos, wherein the video resource list includes multiple resource addresses of multiple videos; the multiple videos include the main video and the one or more spliced ​​videos.

[0086] Step S906: Send the video resource list to the client, and the client is used to: obtain video additional information of at least two videos to be played based on the multiple resource addresses; combine the respective video additional information according to the video presentation order to obtain the resources to be played; and send the resources to be played to the client so that the video additional information of the resources to be played is presented to the viewer in the form of a single video.

[0087] The server can query the spliced ​​videos associated with the main video based on the video ID of the main video. The server can generate a spliced ​​video ID list based on the determined video ID of the spliced ​​video. Based on the spliced ​​video ID list and the video ID of the main video, the server can query and obtain the resource addresses of the corresponding video IDs from the video cloud. Video cloud is a video service solution based on cloud computing technology that can provide users with convenient, efficient, and low-cost video-related services. The server assembles the multiple resource addresses obtained into a video resource list and sends the list to the client. In the process of generating the resource list, the server can flexibly adjust the position of the resource address corresponding to the spliced ​​video. At the same time, it can obtain more targeted resource addresses of the spliced ​​video based on actual conditions to achieve dynamic adjustment of the spliced ​​video, thereby more accurately expanding the video content of the main video. In some embodiments, the server can determine whether the input parameters of the video request carry a spliced ​​video ID list. If a spliced ​​video ID list exists, the server can directly obtain the corresponding resource address from the video cloud through the spliced ​​video ID list.

[0088] In this embodiment, the server sends a video resource list to the client, so that the client can play multiple videos in sequence according to the resource addresses in the resource list. In this way, the server does not need to transcode and merge multiple videos, thereby reducing the server's computing cost.

[0089] Regarding determining the spliced ​​video, in an optional embodiment, the method further includes: Step 1000: Determine whether the video ID of the main video is in a preset list.

[0090] Step 1002: When the video identifier of the main video is located in the preset list, determine the one or more spliced ​​videos.

[0091] The preset list can be a black and white list of spliced ​​videos. The black and white list of videos is checked according to the video identifier of the main video. If the video identifier of the main video is on the white list of the black and white list, the spliced ​​video associated with the main video can be found according to the video identifier of the main video. In some embodiments, the resource position of the main video that can be spliced ​​can be queried, such as how many videos can be spliced ​​before the main video and how many videos can be spliced ​​after the main video. In some embodiments, the corresponding spliced ​​video identifier list can also be queried according to the video information of the main video, for example, the corresponding spliced ​​video identifier list can be obtained according to the episode information in the video information.

[0092] In this embodiment, video splicing can be performed on a specific main video through a preset list to expand the video content.

[0093] Regarding barrage processing, in an optional embodiment, the method further includes: Step 1100: Obtain the bullet comment data of each spliced ​​video.

[0094] Step 1102: Update the barrage pool of the main video according to the barrage data of the main video and the barrage data of the spliced ​​video; in the barrage pool, the pop-up time of each barrage data is offset according to the total duration of the multiple videos.

[0095] In order to make this application easier to understand, the following Figure 12 、 13 An exemplary application is provided.

[0096] like Figure 12 As shown, take the user requesting video playback as an example.

[0097] Step S1: The client sends a video request to the server, where the video request includes a video identifier of the main video.

[0098] Step S2: The server determines one or more spliced ​​videos based on the video identifier of the main video.

[0099] The server can determine one or more spliced ​​videos associated with the main video based on the video ID of the main video. The server can also determine one or more spliced ​​videos based on the video ID of the main video and a preset list.

[0100] Step S3: The server generates a video resource list based on the main video and one or more spliced ​​videos.

[0101] Step S4: The server returns the video resource list to the client.

[0102] Step S5: The client obtains video additional information of at least two videos to be played according to the multiple resource addresses in the video resource list and combines the video additional information according to the video presentation order to obtain the resource to be played.

[0103] Step S6: Play the resource to be played.

[0104] like Figure 13 As shown, the multiple videos in the resources to be played may include a main video, a spliced ​​video A, a spliced ​​video B, a spliced ​​video C, and a spliced ​​video D. The progress and duration of the multiple videos can be divided. The progress can be divided into display progress and main video progress. The display progress is the sum of the progress of the main video plus the duration of the video before the main video. The main video progress is the actual progress of the main video. The duration can be divided into display duration and the duration of each video. The display duration is the sum of the time of all videos. In this way, during the playback of multiple videos, the multiple videos are equivalent to a complete video from the user's perspective, which can provide users with a complete playback experience.

[0105] During the playback process, the next video of the current video can be preloaded. For example, before the playback of the spliced ​​video A is completed, the spliced ​​video B can be preloaded.

[0106] During sequential playback, when spliced ​​video A finishes playing and a video switch is required, the last frame of video A can be extracted to generate the first canvas image, which is overlaid on the video element, and then the player switches to the video. When the first frame of spliced ​​video B appears, the first canvas image is removed, and spliced ​​video B plays normally.

[0107] When a user jumps to another video, such as from Spliced ​​Video A to the main video, the player extracts the current frame of Spliced ​​Video A to generate a second canvas image. This second canvas image is then overlaid on the video element, and the player switches the video. When the target frame of the main video corresponding to the jump instruction appears, the second canvas image is removed, and the main video plays normally.

[0108] Step S7: The client sends the video list of the spliced ​​video to the server.

[0109] Step S8: The server obtains the bullet comment data of each spliced ​​video according to the video list of the spliced ​​video.

[0110] Step S9: The server integrates the bullet screen data of the main video and the bullet screen data of the spliced ​​video, and offsets the pop-up time of the bullet screen data according to the duration of the main video and the spliced ​​video.

[0111] Step S10: The server sends the bullet comment data after the offset time to the client.

[0112] Step S11: The client displays the bullet screen according to the bullet screen data.

[0113] Step S12: The client reports the display data of the spliced ​​video to the server.

[0114] The server obtains the display data of the spliced ​​video to facilitate subsequent optimization of the splicing expansion of the main video.

[0115] In this exemplary application, the sense of playback fragmentation caused by video switching is reduced, so that seamless switching of multiple videos can be achieved from the user's perspective, thereby improving the user's viewing experience.
