[0085] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0086] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein. Obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0087] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way. In addition, in the description of the embodiments of the present application, unless otherwise specified, the meaning of "multiple" refers to two or more.

[0088] In the video consumption scenario, the core interface is generally designed to interact with data in a paging mode. Each time the client initiates a request, the server obtains the full access information of the specified number of videos and returns it to the client. In this way, the client can obtain the full playback data of these videos in advance. When the user switches videos, the switched video can be played immediately without additional network requests. Figure 1As shown, under the paging data interaction system, the process of the client accessing video data includes: 1. The client device sends a request to the server. 2. The server determines at least one video to be accessed according to the video recommendation algorithm, the video aggregation algorithm, etc. 3. The server obtains the access information of each video to be accessed. Among them, the access information of the video to be accessed includes: the access address of the native video segment in the video to be accessed, the access address of the picture in the video to be accessed, and the access address of the metadata of the sticker in the video to be accessed. Obtaining the access address of the native video segment in the video to be accessed needs to rely on the downstream service of the server, specifically: sending the ID of the native video segment to the microservice of the video architecture, and receiving the access address of the native video segment returned by the microservice of the video architecture. Obtaining the access address of the picture in the video to be accessed does not need to rely on the downstream service of the server, and can be directly read through the core storage service. Obtaining the access address of the metadata of the sticker in the video to be accessed also needs to rely on the downstream service of the server. 4. The server sends the access information of each video to be accessed to the client device. 5. The client device obtains the playback data of each video to be accessed according to the access information of each video to be accessed. Since the server needs to interact with downstream services in the process of obtaining access information such as the access address of the native video in the video to be accessed and the access address of the sticker metadata, network overhead will be generated between the server and the downstream services in the process of obtaining the access information of the video to be accessed.

[0089] In the business scenario where video creation only supports one video or multiple images, when obtaining the access information of a video, it is only necessary to obtain the access address of one native video at most. Therefore, the network overhead between the server and the downstream service in the process of obtaining the access information of the video to be accessed is still within the acceptable range. However, after video creation supports multiple videos and multiple images mixed, the paging mode of sending full access information is still used to design data interaction. After receiving the request from the client, the server needs to obtain the access information of each segment in each video, and obtaining the access information of a video may require obtaining the access addresses of multiple native videos. Therefore, the network overhead between the server and the downstream service will swell to a very large level. For example: each time the server receives a request from a client device, it determines 10 videos to be accessed. Each video to be accessed includes 100 native video clips. For one request sent by the client device, the server needs to obtain the access addresses of 10*100 native video clips through the downstream service. Even if a single call to the downstream service can obtain the access addresses of 20 native video clips, 50 calls to the downstream service are required. Compared with the business scenario where video creation only supports one video or multiple pictures, the network overhead between the server and the downstream service has expanded 50 times.

[0090] The user's video viewing behavior will cause some of the network overhead between the server and downstream services to be invalid. For example: the server obtains the access information of all the segments of a certain video and sends it to the client device. When watching the video, the user may only watch the first few segments of the video because he is not interested in the video, and then switch to watch other videos, which will cause the network overhead between the server and the downstream service caused by obtaining the access information of the unwatched segments to be invalid. Based on the above content, in order to reduce the network overhead between the server and the downstream services, the embodiment of the present application provides the following technical solution.

[0091] Reference Figure 2 As shown, the embodiment of the present application provides a method for accessing video data, referring to Figure 2 As shown, the method for accessing the video data includes the following steps:

[0092] S201. A client device sends a first video request to a server.

[0093] Correspondingly, the server receives the first video request sent by the client device.

[0094] In some embodiments, the first video request may be a video recommendation request. For example, the terminal device displays videos based on a waterfall view, and monitors in real time whether the number of cached videos is less than a threshold number when the user switches videos by sliding up and down, and triggers the client device to send a video recommendation request to the server when the number of cached videos is less than the threshold number.

[0095] In some embodiments, the first video request may also be a video search request. For example, when a user searches for a video based on a keyword, the client device sends a video search request carrying the keyword to the server. For example, in a daily aggregation scenario where videos posted within a preset time are aggregated into one video, the first video request may be to obtain videos posted by the current user within the preset time.

[0096] S202: The server obtains segment information of the target video in response to the first video request.

[0097] The target video is any video whose access information is to be sent to the client device, and the segment information of the target video includes tags of each segment of the target video. The tag of any segment is used to indicate whether the access information of the segment needs to be obtained through downstream services.

[0098] The target video may include multiple native videos and multiple pictures at the same time, and the video content corresponding to each video or each picture is called a segment of the target video.

[0099] In some embodiments, the implementation method for the server to obtain the segment information of the target video may include: obtaining the identification information of the target video, and reading the segment information of the target video from a preset storage space according to the identification information of the target video and the correspondence between the identification information and the segment information of the target video.

[0100] In some embodiments, the tag of the fragment can be 0 or 1. When the tag of the fragment is 0, it means that the access information of the fragment does not need to be obtained through the downstream service. When the tag of the fragment is 1, it means that the access information of the fragment needs to be obtained through the downstream service.

[0101] S203: The server determines whether to send access information of all segments of the target video to the client device according to the segment information of the target video.

[0102] That is, whether to paginate the target video is determined according to the segment information of the target video, and only the access information of a segment of the target video is sent to the client device.

[0103] In the above step S203, if it is determined to send the access information of all the segments of the target video to the client device, the access information of all the segments of the target video is obtained, and the access information of all the segments of the target video is sent to the client device; if it is determined not to send the access information of all the segments of the target video to the client device, the following step S204 is executed:

[0104] S204: The server obtains access information of each first-category segment and access information of each second-category segment in the target segment interval.

[0105] The first type of fragments are fragments whose access information does not need to be obtained through downstream services, and the second type of fragments are fragments whose access information needs to be obtained through downstream services.

[0106] In some embodiments, access information for obtaining pictures does not need to go through downstream services, while access information for obtaining videos and stickers needs to go through downstream services. Therefore, the first category of clips can be the video content corresponding to the pictures, and the second category of clips can be the video content corresponding to the pictures with stickers, the video content corresponding to the videos, and the video content corresponding to the videos with stickers.

[0107] Since the first category of fragments are fragments whose access information does not need to be obtained through downstream services, the server obtaining the access information of the first category of fragments will not cause network overhead between the server and the downstream service. For the second category of fragments whose access information needs to be obtained through downstream services, only the access information of a part of the second category of fragments (the second category of fragments within the target fragment interval) is obtained, and the access information of the remaining other fragments will be obtained only when needed, and the access information of the remaining other fragments will not be obtained when not needed. Therefore, the embodiment of the present application can reduce the network overhead between the server and the downstream service.

[0108] S205. The server sends access information of each first-category segment and access information of each second-category segment in the target segment interval to the client device.

[0109] Correspondingly, the client device receives the access information of each first-category segment and the access information of each second-category segment in the target segment interval sent by the server.

[0110] S206. The client device obtains the playback data of each first category segment of the target video and the playback data of each second category segment in the target segment interval according to the access information of each first category segment of the target video and the access information of each second category segment in the target segment interval.

[0111] The video data access method provided by the embodiment of the present application, upon receiving a first video request sent by a client device, first obtains the segment information of the target video in response to the first video request, then determines whether to send the access information of all the segments of the target video to the client device according to the segment information of the target video, and, if it is determined that the access information of all the segments of the target video is not to be sent to the client device, obtains the access information of each first-category segment and the access information of each second-category segment in the target segment interval, and sends the access information of each first-category segment and the access information of each second-category segment in the target segment interval to the client device. Since the embodiment of the present application, when it is determined that the access information of all the segments of the target video is not to be sent to the client device, only needs to obtain the access information of the first-category segment whose access information does not need to be obtained through the downstream service and the access information of the second-category segment whose access information in the target segment interval needs to be obtained through the downstream service, therefore, compared with obtaining the access information of all the segments in the target video, the embodiment of the present application can reduce the network overhead between the server and the downstream service.

[0112] As an extension and refinement of the above embodiment, the present application embodiment also provides another method for accessing video data, referring to Figure 3 As shown, the method for accessing the video data includes the following steps:

[0113] S301. A client device sends a first video request to a server.

[0114] Correspondingly, the server receives the first video request sent by the client device.

[0115] S302: The server obtains segment information of the target video in response to the first video request.

[0116] The target video is any video whose access information is to be sent to the client device, and the segment information of the target video includes tags of each segment of the target video. The tag of any segment is used to indicate whether the access information of the segment needs to be obtained through downstream services.

[0117] In some embodiments, the segment information of the target video is pre-generated by the server and stored in a preset storage space. When the segment information of the target video needs to be obtained, it can be directly read from the preset storage space.

[0118] In some embodiments, the implementation method for the server to generate and save the segment information of the target video may include the following steps: determining the content of each segment of the target video; if the content of the first segment of the target video is a picture, determining that the access information of the first segment does not need to be obtained through a downstream service; if the content of the second segment of the target video is a picture or video with stickers or a video with stickers, determining that the access information of the second segment needs to be obtained through a downstream service; based on whether the access information of each segment of the target video needs to be obtained through a downstream service, generating and saving the segment information of the target video.

[0119] In the embodiments of the present application, the bitmap concept can be used to record or save the labels of each segment of the target video (segment information of the target video) with one or more label sequences. In some embodiments, based on whether the access information of each segment of the target video needs to be obtained through a downstream service, the segment information of the target video is generated and saved, including: traversing each segment of the target video, if the access information of the current segment does not need to be obtained through a downstream service, the label corresponding to the current segment is set to a first preset value, if the access information of the current segment needs to be obtained through a downstream service, the label corresponding to the segment is set to a second preset value to obtain the label sequence of the target video; obtain the segment information of the target video according to the label sequence; save the segment information of the target video to a preset storage space.

[0120] Exemplarily, when the first preset value is 0, the second preset value is 1, the target video includes 30 segments, and the first, fourth, fifth, seventh, eleventh, fifteenth, seventeenth, eighteenth, twenty-fourth, twenty-sixth, and twenty-ninth segments of the target video are segments whose access information needs to be obtained through downstream services, and the remaining segments are segments that do not need to be obtained through downstream services, then the tag sequence of the target video can be as follows:

[0121] 100110100010001011000001010010.

[0122] Furthermore, when saving the target video segment information, the target video tag sequence can be directly saved as the target video segment information, and the target video tag sequence can be compressed to reduce the storage space occupied by the target video segment information. For example, the target video tag sequence can be first taken as a decimal number, and converted into a hexadecimal value, and the largest hexadecimal value can be saved as a string attribute.

[0123] It should be noted that, although the bitmap concept can be used to record or save the labels of each segment of the target video (segment information of the target video) in the embodiment of the present application, the storage form of the segment information of the target video is not limited in the embodiment of the present application, and the labels of each segment of the target video can be obtained according to the segment information of the target video. For example: the segment information of the target video can be saved in the form of a mapping relationship table between labels and segment indexes, and for another example: the segment information of the target video can also be saved in the form of a string composed of the label values ​​of each segment.

[0124] S303: The server obtains the total number of segments of the target video according to the segment information of the target video.

[0125] In some embodiments, the total number of segments of the target video may be determined based on tag data in the segment information of the target video.

[0126] S304: The server determines whether the total number of segments of the target video is greater than a preset number of segments.

[0127] In some embodiments, the preset number of segments may be the number of segments within the target segment interval.

[0128] In the above embodiment, if the total number of segments of the target video is less than or equal to the preset number of segments, the following step S305 is performed:

[0129] S305: The server determines to send access information of all segments of the target video to the client device.

[0130] For example, if the total number of segments of the target video is 15 and when paging the video, access information of the first 20 segments needs to be sent for the first time, then there is no need to paging the target video.

[0131] In the above step S304, if the total number of segments of the target video is greater than the preset number of segments, the following step S306 is performed:

[0132] S306: The server determines whether the remaining segments except the segments in the target segment interval include the second type of segments.

[0133] In the above step S306, if the remaining fragments do not include the second type of fragments, obtaining the access information of the remaining fragments will not bring network overhead between the server and the downstream service, so there is no need to paginate the target video, so return to the above step S305 to determine to send the access information of all the fragments of the target video to the client device.

[0134] In the above step S306, if the remaining fragments include the second type of fragments, obtaining access information of the remaining fragments will bring network overhead between the server and the downstream service, so the following step S307 is performed:

[0135] S307: The server determines not to send access information of all segments of the target video to the client device.

[0136] After determining not to send access information of all segments of the target video to the client device, the embodiment of the present application continues to perform the following steps:

[0137] S308: Determine the paging direction of the target video.

[0138] Generally, videos are watched sequentially starting from the first segment, but in some special scenarios, there may be a need to play the video in reverse order from the end. For example, in daily aggregation scenarios, when a user clicks to start playing a video, it will automatically jump to the earliest unread work. At this time, the user may need to play it in reverse order from the back to the front. Therefore, in an embodiment of the present application, the paging direction of the target video can be sequential or reverse.

[0139] S309: Determine the target segment interval according to the paging direction of the target video and a preset interval length.

[0140] In some embodiments, if the paging direction of the target video is sequential, the target segment interval includes a preset interval length of video segments at the head of the target video. For example, if the preset interval length is 20, the target segment interval includes the first 20 segments of the target video.

[0141] In some embodiments, if the target video is paginated in reverse order, the target segment interval includes a preset segment length of video segments at the end of the target video. For example, if the preset segment length is 15, the target segment interval includes the last 15 segments of the target video.

[0142] In some embodiments, determining the paging direction of the target video includes: determining whether the first video request carries direction indication information; if the first video request does not carry indication information, using the default sequential direction as the paging direction of the target video; and if the first video request carries indication information, determining the paging direction of the target video in reverse order.

[0143] S310. The server obtains access information of each first-category segment and access information of each second-category segment in a target segment interval.

[0144] S311. The server sends access information of each first-category segment and access information of each second-category segment in the target segment interval to the client device.

[0145] Correspondingly, the client device receives the access information of each first-category segment and the access information of each second-category segment in the target segment interval sent by the server.

[0146] S312. The client device obtains the playback data of each first-category segment of the target video and the playback data of each second-category segment in the target segment interval according to the access information of each first-category segment of the target video and the access information of each second-category segment in the target segment interval.

[0147] exist Figure 2 The embodiment shown or Figure 3 Based on the embodiment shown, refer to Figure 4 As shown, the method provided in the embodiment of the present application also includes the following steps:

[0148] S401: The server generates paging information of the target video.

[0149] Among them, the paging information includes: at least one of: first indication information, second indication information and third indication information, the first indication information is used to indicate that the target video also includes remaining segments other than the target segment interval; the second indication information is used to indicate the starting position of the remaining segments, and the third indication information is used to indicate the paging direction of the target video.

[0150] S402: The server sends paging information of the target video to the client device.

[0151] Correspondingly, the client device receives the paging information of the target video sent by the server.

[0152] It should be noted that the paging information of the target video can be sent to the client device independently, or can be sent to the client device together with the access information of each first-category segment and the access information of each second-category segment in the target segment interval.

[0153] S403: During the process of playing the target video, the client device determines in real time whether the cached playback duration of the target video is less than a threshold duration.

[0154] That is, during the process of playing the target video based on the playback data of each first-category segment of the target video and the playback data of each second-category segment within the target segment interval, the client device determines in real time whether the cached playback time of the target video is less than the threshold time.

[0155] In the above step S403, if the cached playback duration of the target video is less than the threshold duration, the following step S404 is executed:

[0156] S404: The client device sends a second video request to the server.

[0157] Correspondingly, the server receives the second video request sent by the client device.

[0158] The second video request carries the paging information of the target video.

[0159] S405: The server obtains access information of each remaining second-category segment in response to the second video request.

[0160] The remaining second-category segments are the second-category segments in the remaining segments except the target segment interval.

[0161] S406: The server sends access information of each remaining second-category segment to the client device.

[0162] Correspondingly, the client device receives access information of each remaining second-category segment of the target video sent by the server.

[0163] After sending the access information of each first-category fragment and the access information of each second-category fragment in the target fragment interval to the client device, only the access information of the remaining second-category fragments has not been sent to the client device. Therefore, after the server sends the access information of each remaining second-category fragment to the client device, the client device can obtain the full playback data of the target video, thereby supporting the complete playback of the target video.

[0164] S407: The client device obtains the playback data of each remaining second-category segment of the target video according to the access information of each remaining second-category segment of the target video.
