[0085] In order to enable the above and other objectives of the present application to be more clearly understood and to be realized, a more detailed description of the present application will be rendered by reference to the following scheme. It is to 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, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in other manners different from those described herein. It is apparent that the embodiments described in the specification are only a part of the embodiments of the present application, and not all the embodiments.

[0087] In the embodiments of the present application, the words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or advantageous than other embodiments or design schemes. Rather, the words "exemplary" or "for example" are used to present relevant concepts in a concrete manner. In addition, in the description of the embodiments of the present application, the meaning of "plurality" is two or more, unless otherwise specified.

[0088] In the consumption scenario of a video, the core interface is generally designed for data interaction in a paging mode. The client initiates a request each time, the server obtains full access information of a specified number of videos, and returns the information to the client. In this way, the client can obtain full playback data of the videos in advance, and the user can immediately play the switched video without additional network requests when switching videos. For details, refer to Figure 1As shown, under the paging data interaction system, the process of video data access by the client includes: 1. The client device sends a request to the server. 2. The server determines at least one video to be accessed according to a video recommendation algorithm, a video aggregation algorithm, etc. 3. The server obtains access information of each video to be accessed. The access information of the video to be accessed includes: access address of a native video segment in the video to be accessed, access address of a picture in the video to be accessed, and access address of metadata of a sticker in the video to be accessed, etc. 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. 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. 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 the downstream service in the process of obtaining the access information of the native video in the video to be accessed, the network overhead between the server and the downstream service will be generated in the process of the server obtaining the access information of the video to be accessed.

[0089] In the business scenario where video creation only supports one video or multiple pictures, when obtaining the access information of a video, at most only the access address of one native video needs to be obtained, so 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 bearing range, but after video creation supports multiple videos and multiple pictures mixed arrangement, the paging mode of sending full access information is still used for designing data interaction. Since the server needs to obtain the access information of each segment in each video after receiving the request of the client, and obtaining the access information of a video may need to obtain the access addresses of multiple native videos, the network overhead between the server and the downstream service will be inflated to a very large value. For example: the server receives a request sent by the client device each time, determines 10 videos to be accessed, each video to be accessed includes 100 native video segments, then for one request sent by the client device, the server needs to obtain the access addresses of 10*100 native video segments through the downstream service. Even if a single call to the downstream service can obtain the access addresses of 20 native video segments, 50 calls to the downstream service are still needed. 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 is inflated by 50 times.

[0090] The video watching behavior of a user can cause part of network overhead between a server and a downstream service to be invalid. For example, the server obtains access information of all segments of a certain video and sends the access information to a client device. When the user watches the video, the user can only watch the first few segments of the video and then switch to watch other videos because the user is not interested in the video, thereby causing network overhead between the server and the downstream service caused by obtaining access information of segments that are not watched to be invalid. Based on the foregoing, in order to reduce network overhead between the server and the downstream service, an embodiment of the present application provides the following technical solutions.

[0091] Referring to Figure 2 FIG. 1, an embodiment of the present application provides a video data access method. Referring to Figure 2 FIG. 2, the video data access method 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 can be a video recommendation request. For example, the terminal device displays videos based on a waterfall view. The terminal device monitors whether the number of cached videos is less than a threshold number in real time during switching of videos by the user through up and down sliding, 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 can also be a video search request. For example, when the user searches for videos based on a keyword, the client device sends a search video request carrying the keyword to the server. For example, in a daily aggregation scene in which videos published within a preset time period are aggregated into one video, the first video request can be to obtain videos published by the current user within the preset time period.

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

[0097] The target video is any video for which access information is to be sent to the client device. The segment information of the target video includes labels of each segment of the target video. The label of any segment is used to indicate whether access information of the segment needs to be obtained through a downstream service.

[0098] The target video can include multiple original videos and multiple pictures at the same time. Video content corresponding to each video or each picture is referred to as a segment of the target video.

[0099] In some embodiments, the implementation of the server obtaining the segment information of the target video can include: obtaining 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 a corresponding relationship between the identification information and the segment information of the target video.

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

[0101] S203, the server determines whether to send the 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, according to the segment information of the target video, it is determined whether to page 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 segments of the target video to the client device, the access information of all segments of the target video is obtained, and the access information of all segments of the target video is sent to the client device; and if it is determined not to send the access information of all segments of the target video to the client device, the following step S204 is performed:

[0104] S204, the server obtains the access information of each first type segment and the access information of each second type segment in the target segment interval.

[0105] The first type segment is a segment whose access information does not need to be obtained through the downstream service, and the second type segment is a segment whose access information needs to be obtained through the downstream service.

[0106] In some embodiments, the access information of the picture does not need to be obtained through the downstream service, and the access information of the video and the sticker needs to be obtained through the downstream service, so the first type segment can be the video content corresponding to the picture, and the second type segment can be the video content corresponding to the picture with the sticker, the video content corresponding to the video, and the video content corresponding to the video with the sticker.

[0107] Since the first type of segment is a segment whose access information does not need to be acquired through the downstream service, the server acquiring the access information of the first type of segment does not bring network overhead between the server and the downstream service, and for the second type of segment whose access information needs to be acquired through the downstream service, only the access information of a part of the second type of segment (the second type of segment in the target segment interval) is acquired, and subsequently, the access information of the remaining other segments is acquired only when needed and is not acquired when not needed, so that the present embodiment can reduce the network overhead between the server and the downstream service.

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

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

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

[0111] The video data access method provided by the present embodiment, when receiving the first video request sent by the client device, first acquires the segment information of the target video in response to the first video request, then determines whether to send the access information of all segments of the target video to the client device according to the segment information of the target video, and in the case of determining not to send the access information of all segments of the target video to the client device, acquires the access information of each first type of segment and the access information of each second type of segment in the target segment interval, and sends the access information of each first type of segment and the access information of each second type of segment in the target segment interval to the client device. Since the present embodiment only needs to acquire the access information of the first type of segment whose access information does not need to be acquired through the downstream service and the access information of each second type of segment in the target segment interval whose access information needs to be acquired through the downstream service in the case of determining not to send the access information of all segments of the target video to the client device, compared with acquiring the access information of all segments in the target video, the present embodiment can reduce the network overhead between the server and the downstream service.

[0112] As an extension and refinement of the above-mentioned embodiments, the present embodiment also provides another video data access method, which, as shown in Figure 3 The video data access method comprises the following steps:

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

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

[0115] S302, the server acquires segment information of a target video in response to the first video request.

[0116] The target video is any video for which access information is to be sent to the client device, and the segment information of the target video includes labels of each segment of the target video, where a label of any segment is used to indicate whether access information of the segment needs to be acquired through a downstream service.

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

[0118] In some embodiments, the implementation manner in which the server generates and saves the segment information of the target video can include the following steps: determining the content of each segment of the target video; if the content of a first segment of the target video is a picture, determining that access information of the first segment does not need to be acquired through a downstream service; if the content of a second segment of the target video is a picture with a sticker or a video with a sticker or a video with a sticker, determining that access information of the second segment needs to be acquired through a downstream service; and generating and saving the segment information of the target video according to whether access information of each segment of the target video needs to be acquired through a downstream service.

[0119] In the embodiments of the present application, the labels (segment information of the target video) of each segment of the target video can be recorded or saved by bitmap idea with one or more label sequences. In some embodiments, generating and saving the segment information of the target video according to whether access information of each segment of the target video needs to be acquired through a downstream service includes: traversing each segment of the target video, if access information of a current segment does not need to be acquired through a downstream service, setting a label corresponding to the current segment to a first preset value, if access information of the current segment needs to be acquired through a downstream service, setting the label corresponding to the segment to a second preset value, to acquire a label sequence of the target video; acquiring the segment information of the target video according to the label sequence; and saving the segment information of the target video into a preset storage space.

[0120] For example, 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 that need to be acquired through the downstream service, and the remaining segments are segments that do not need to be acquired through the downstream service, the tag sequence of the target video can be as follows:

[0121] 100110100010001011000001010010.

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

[0123] It should be noted that, although the bitmap idea can be used to record or save the tags of the segments of the target video (the segment information of the target video) in the embodiments of the present application, the form of saving the segment information of the target video is not limited in the embodiments of the present application, and the tags of the segments of the target video can be acquired 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 of tags and segment indexes, and for another example, the segment information of the target video can be saved in the form of a string composed of tag values of the segments.

[0124] S303, the server acquires the total segment quantity of the target video according to the segment information of the target video.

[0125] In some embodiments, the total segment quantity of the target video can be determined according to the tag data in the segment information of the target video.

[0126] S304, the server determines whether the total segment quantity of the target video is greater than a preset segment quantity.

[0127] In some embodiments, the preset segment quantity can be the quantity of the segments in the target segment range.

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

[0129] S305, the server determines to send the access information of all the 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 the first 20 segments of the target video are required to be sent to the client device, it is not necessary to page the target video.

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

[0132] In step S306, the server determines whether the second type of segments is included in the remaining segments other than the segments in the target segment interval.

[0133] In step S306, if the second type of segments is not included in the remaining segments, obtaining the access information of the remaining segments does not cause network overhead between the server and the downstream service, and therefore it is not necessary to page the target video, and step S305 is returned to determine whether to send the access information of all segments of the target video to the client device.

[0134] In step S306, if the second type of segments is included in the remaining segments, obtaining the access information of the remaining segments causes network overhead between the server and the downstream service, and therefore step S307 is performed.

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

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

[0137] In step S308, the paging direction of the target video is determined.

[0138] In general, video watching starts from the first segment and plays in sequence, but in some special scenarios, there is a demand to play in reverse order from the tail of the video. For example, in a daily aggregation scenario, a user jumps to the earliest unread work when starting to play a video, and at this time, the user may need to play in reverse order from the back to the front. Therefore, in the embodiment of the application, the paging direction of the target video can be a sequence direction or a reverse direction.

[0139] In step S309, the target segment interval is determined according to the paging direction of the target video and the preset interval length.

[0140] In some embodiments, the paging direction of the target video is a sequence direction, and the target segment interval includes the 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, the target video has a reverse direction of the paging direction, and the target segment interval includes a preset interval length of video segments at a tail of the target video. For example, the preset interval length is 15, and 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, and if the first video request does not carry the indication information, using a default order direction as the paging direction of the target video, and if the first video request carries the indication information, determining the paging direction of the target video as a reverse direction.

[0143] S310, the server acquires access information of each first type segment and access information of each second type segment in the target segment interval.

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

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

[0146] S312, the client device acquires the play data of each first type segment of the target video and the play data of each second type segment in the target segment interval according to the access information of each first type segment of the target video and the access information of each second type segment in the target segment interval.

[0147] In Figure 2 the embodiments shown in the specification or Figure 3 the embodiments shown in the specification, the method provided by the embodiments of the present application further includes the following steps: Figure 4

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

[0149] 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 further includes remaining segments other than the target segment interval, the second indication information is used to indicate a starting position of the remaining segments, and the third indication information is used to indicate a paging direction of the target video.

[0150] S402, the server sends the 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 type segment and the access information of each second type segment in the target segment interval.

[0153] S403, the client device determines whether the cache playing duration of the target video is less than the threshold duration in real time during playing the target video.

[0154] That is, the client device determines whether the cache playing duration of the target video is less than the threshold duration in real time during playing the target video based on the playing data of each first type segment of the target video and the playing data of each second type segment in the target segment interval.

[0155] In the above step S403, if the cache playing duration of the target video is less than the threshold duration, the following step S404 is performed:

[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 acquires the access information of each remaining second type segment in response to the second video request.

[0160] The remaining second type segment is the second type segment in the remaining segment except the target segment interval.

[0161] S406, the server sends the access information of each remaining second type segment to the client device.

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

[0163] After sending the access information of each first type segment and the access information of each second type segment in the target segment interval to the client device, only the access information of the remaining second type segment is not sent to the client device. Therefore, after the server sends the access information of each remaining second type segment to the client device, the client device can acquire the full playing data of the target video, thereby supporting complete playing of the target video.

[0164] S407, the client device acquires the playing data of each remaining second type segment of the target video according to the access information of each remaining second type segment of the target video.
