Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions in the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without inventive step, are intended to be within the scope of the present disclosure.
The following explains an application scenario of the embodiment of the present disclosure:
fig. 1 is an application scene diagram of a video cache playing method provided in an embodiment of the present disclosure, and the video cache playing method provided in the embodiment of the present disclosure may be applied in a scene of non-Feed stream video resource access of a video application client. An execution subject of the method provided by this embodiment may be a terminal device 11, for example, a smart phone, and more specifically, as shown in fig. 1, the terminal device 11 is connected to a server 12, and a user accesses, through a video class application client (hereinafter, referred to as a client) running in the terminal device 11, video resources in video partitions of specified categories, items, and identifiers, for example, video pages (video partitions) where all video resources (shown as video1 to video6 in fig. 1) published by an X studio are located are accessed, and after clicking any one of the video resources, the video resource is played. And then, based on the sliding operation of the user, the currently played video can be switched to other video resources in the video page for playing.
In the prior art, video switching operation in video APP is usually based on a Feed stream scene, in this scene, a user can cache a subsequent video of a current video in advance based on a Feed stream in a video switching process, so that the subsequent video cached in advance can be smoothly loaded and played when being switched to the current video, however, in a non-Feed stream scene, the APP client cannot cache the subsequent video of the current video in advance based on the Feed stream. For example, when a user enters a video page of a specific user to select a video for playing, the selected video is generally random, and then when the user switches videos through a sliding operation, the sliding direction is also random, which causes switching of the current video to a previous video or a next video, so that it is impossible to determine which direction of video resources on both sides (previous or next) of the current video are cached, and further, problems of subsequent video loading delay, playing jam and the like after video switching are caused. Meanwhile, if the video resources on both sides of the current video are loaded, the buffering time of the video resources is increased due to bandwidth limitation, especially under the condition of mobile network access, which results in waste of user traffic and bandwidth on one hand and still causes the problem of blocking of subsequent video playing on the other hand. The embodiment of the present disclosure provides a video cache playing method to solve the above problem.
Referring to fig. 2, fig. 2 is a first schematic flow chart of a video cache playing method according to an embodiment of the present disclosure. The method of the embodiment can be applied to terminal equipment, and the video cache playing method comprises the following steps:
step S101, playing a first video in the video resource sequence.
Specifically, in a possible implementation manner, the video resource sequence may be a playlist, where the playlist corresponds to video playing addresses in multiple video resource servers, where the playlist includes a video playing address corresponding to a first video, and by accessing the playing address corresponding to the first video in the video resource server, video data corresponding to the first video may be obtained, and the video data corresponding to the first video is downloaded to the local terminal device, and is played after the processes of loading, transcoding, and the like are performed. In another possible implementation manner, the video resource sequence is description information for characterizing a set of one or more videos, and the video resource sequence may be an access address, for example, "www.video.example.com/user _001", where a plurality of video files, for example, "video1", "video2", "video3", and the like, are included. Illustratively, among others, "video2" may be the first video in a sequence of video assets. And adding the file name of the video file after the access address corresponding to the video resource sequence to obtain the corresponding video resource.
Specifically, a client running a video application in a terminal device may determine a video resource sequence and play a first video in a video resource list by connecting the terminal device through video resources displayed on a client interface based on a user operation, the client responds to a click operation of the user, and a process of playing the video is the prior art known by those skilled in the art and is not described herein again.
Step S102, when a first sliding operation aiming at a first video is detected, determining a video caching direction according to a sliding direction corresponding to the first sliding operation; the first sliding operation is used for switching the first video into a second video adjacent to the first video in the video resource sequence to be played, and the video cache direction represents the playing direction of the video resource in the video resource sequence.
Illustratively, the terminal device is provided with a touch screen for man-machine interaction, and the terminal device detects the operation behavior of the user on the terminal device through the touch screen. Specifically, in the process that the terminal device plays the first video through the client, when the first sliding operation is detected, the terminal device responds to the sliding operation according to an operation rule preset by the client, and switches the currently played first video into the second video. The first sliding operation refers to an operation of sliding along the transverse direction or the longitudinal direction of the screen in an operable area of the touch screen to switch a currently played video, for example, sliding upwards to switch to a previous video; sliding downwards and switching to the next video; or sliding to the left to switch to the previous video; and sliding to the right to switch to the next video.
The second video is a video in the video resource sequence, and the second video can be a previous video or a next video adjacent to the first video; fig. 3 is a schematic diagram of a position relationship between a second video and a first video provided by an embodiment of the present disclosure, as shown in fig. 3, for example, a video resource sequence includes "video1", "video2", "video3", "video4", and "video5". The first video is "video2", and the second video may be "video3" or "video1" based on the sliding direction corresponding to the first sliding operation. Wherein, "video3" can be regarded as a subsequent video of "video 2"; "video1" can be considered as the previous video of "video 2".
Further, the video caching direction is a direction for caching videos in the video resource sequence determined based on the usage habits of the user. Illustratively, the video buffering direction may include a forward direction and a backward direction, wherein the previous item is a direction from the currently playing video to a previous video of the currently playing video, i.e. a loop direction of "video1", "video2", "video3", "video4", "video5", "video1", "8230; \8230in the video resource sequence in the embodiment shown in fig. 3; the back item is a direction from the currently playing video to a next video of the currently playing video, that is, a circulation direction of "video5", "video4", "video3", "video2", "video1", "video5", "\ 8230 \\ 8230:in the video resource sequence in the embodiment shown in fig. 3.
In a possible implementation manner, determining the video caching direction according to the sliding direction corresponding to the first sliding operation includes: acquiring preset historical sliding information, wherein the historical sliding information is used for representing the sliding direction corresponding to at least one third sliding operation detected before the first sliding operation; and determining the video cache direction according to the historical sliding information and the sliding direction corresponding to the first sliding operation. Specifically, if the sliding directions corresponding to the third sliding operations which are continuously performed for the preset number of times before the first sliding operation are the same as the sliding directions corresponding to the first sliding operation, the sliding direction corresponding to the first sliding operation is determined as the video caching direction. For example, before the user performs the first sliding operation, the user also performs two times of third sliding operations, where the sliding directions of the first sliding operation and the second sliding operation are the same, that is, the user performs the sliding operation switching video to one direction three times continuously (that is, the determination rule); and determining the video playing direction corresponding to the sliding direction as the video caching direction. The historical sliding information is preset in the terminal equipment, and after the sliding operation implemented by the user is detected each time, the historical sliding information is updated according to the sliding direction of the sliding operation.
Illustratively, the video buffering direction further comprises a pending direction; namely, when the video caching direction cannot be forward or backward through the sliding direction corresponding to the first sliding operation and the preset judgment rule, the video caching direction is determined to be the undetermined direction.
And S103, determining a third video according to the video caching direction, caching the third video, and generating a cached video, wherein the third video is a video adjacent to the second video in the video resource sequence along the video caching direction.
Illustratively, when a first sliding operation aiming at the first video is detected, the terminal device plays the second video through the running client. After the video caching direction is determined, the video played subsequently, namely the third video, can be predicted according to the video caching direction. The third video may be a previous video or a subsequent video of the second video.
Further, the third video is cached, and a locally stored cached video is generated, wherein the cached video includes one or more video data, and when the cached video includes a plurality of video data, each video data is used for storing one video segment of the third video. Thereby realizing the caching of all or part of the third video. The third video may include one or more videos, and each video in the third video may correspond to one or more cached videos, where a specific form of the cached video is not specifically limited herein.
And step S104, responding to a second sliding operation aiming at the second video, and playing the cached video if the sliding direction corresponding to the second sliding operation is the video caching direction.
Illustratively, in the process that the terminal device plays the second video through the running client, when the user continues to switch the video, a second sliding operation is performed on the terminal device, where the second sliding operation is used to switch the second video to a video adjacent to the second video in the video resource sequence for playing, similar to the first sliding operation. Fig. 4A is a schematic diagram illustrating a correspondence relationship between a sliding operation and a playing direction according to an embodiment of the present disclosure, and as shown in fig. 4A, after detecting a second sliding operation, a terminal device may respond to the second sliding operation to switch a second video, and based on the sliding direction of the second sliding operation, play a previous video or a subsequent video of the second video. When the screen is slid down based on the second sliding operation (sliding operation a), the previous video (video 1) of the second video (video 2) is played corresponding to a play direction (play direction a). Fig. 4B is a schematic diagram illustrating a correspondence relationship between a sliding operation and a playing direction according to an embodiment of the present disclosure, and as shown in fig. 4B, when a screen is slid upward based on a second sliding operation (sliding operation B), a video (video 3) subsequent to the second video is played, which corresponds to another playing direction (playing direction B). Accordingly, the correspondence between the second sliding operation and the playback direction can be determined.
When the playing direction corresponding to the second sliding operation is consistent with the playing direction corresponding to the video caching direction, the predicted video caching direction is correct, and the cached video is played at the moment. In another possible implementation manner, if the playing direction corresponding to the second sliding operation performed by the user is different from the video caching direction, or the video caching direction is an undetermined direction, the cached video is not played, and the video is downloaded and played in a conventional video loading manner.
In the embodiment, by playing a first video in a video resource sequence; when a first sliding operation aiming at a first video is detected, determining a video caching direction according to a sliding direction corresponding to the first sliding operation; the first sliding operation is used for switching the first video into a second video adjacent to the first video in the video resource sequence to be played, and the video cache direction represents the playing direction of the video resource in the video resource sequence; determining a third video according to the video caching direction, caching the third video to generate a cached video, wherein the third video is a video adjacent to the second video in the video resource sequence along the video caching direction; and responding to a second sliding operation aiming at the second video, and if the playing direction corresponding to the second sliding operation is the same as the playing direction corresponding to the video caching direction, playing the cached video. The method provided by the embodiment performs prejudgment on the sliding direction corresponding to the subsequent second sliding operation by detecting the first sliding operation of the user, determines the corresponding video cache direction, and caches the video in the video resource sequence in the video cache direction, so as to generate the cached video.
Referring to fig. 5, fig. 5 is a schematic flowchart illustrating a second method for playing a video cache according to an embodiment of the present disclosure. In this embodiment, steps S102 and S103 are further detailed, and the video cache playing method includes:
step S201, a first video in the video resource sequence is played.
Step S202, when a first sliding operation aiming at a first video is detected, a preset sliding prediction model is obtained, wherein the sliding prediction model is a pre-training model used for predicting a sliding direction corresponding to a second sliding operation after the first sliding operation.
And step S203, determining a confidence value of the sliding direction corresponding to the second sliding operation after the first sliding operation according to the sliding prediction model.
And step S204, if the confidence value is greater than the preset value, determining the playing direction corresponding to the second sliding operation after the first sliding operation output by the sliding prediction model as the video caching direction.
Illustratively, the sliding prediction model is a pre-trained prediction model for predicting the sliding direction of the second sliding operation performed by the user after the first sliding operation is performed. The prediction model can predict the sliding direction of the second sliding operation to be implemented by the user later based on the sliding direction of the first sliding operation of the user and the information such as the content, the duration and the like of the first video and the second video displayed by the terminal equipment. In a possible implementation manner, the sliding prediction model directly outputs the predicted sliding direction, and determines the playing direction of each video in the video resource sequence corresponding to the sliding direction as the video caching direction. In another possible implementation, the sliding prediction model directly outputs a confidence value of the predicted sliding direction. For example, the forward direction is 0.8 and the backward direction is 0.2. Further, according to the confidence value, when the confidence value is greater than a preset value, for example, 0.7, the playing direction corresponding to a second sliding operation after the first sliding operation output by the sliding prediction model is determined as the video buffering direction.
Step S205, according to the video resource sequence, determining video sequencing information, wherein the video sequencing information is used for representing the position sequencing of each video in the video resource sequence.
And step S206, determining the position sequence of the second video in the video resource sequence according to the video sequence information.
Step S207, determining a third video according to the position sequence of the second video in the video resource sequence and the video buffering direction.
The video sequencing information is information for representing position sequencing of each video in the video resource sequence, and when each video in the video resource sequence is played, each video is played according to the playing sequence corresponding to the video sequencing information. The video ordering information may include, for example, an identifier of each video in the video resource sequence for ordering, and according to the video ordering information and the identifier of the second video, a position ordering of the second video in the video resource sequence may be determined. Further, on the basis of determining the position ordering of the second video, based on the video caching direction, an identifier adjacent to the identifier of the second video in the video caching direction is determined, and then a video corresponding to the identifier, that is, a third video, is determined.
Optionally, the third video includes multiple continuous videos in the video resource sequence, as shown in fig. 6, step S207 includes two specific implementation steps S2071 and S2072:
step S2071, obtaining a preset buffer parameter, where the buffer parameter is used to represent the number of videos included in the third video.
Step S2072, according to the buffer parameter, determining a preset number of videos of the second video adjacent to each other along the video buffer direction as a third video.
The caching parameter is information preset in the terminal device, and may be configured in the terminal device through user configuration or during client installation and update. Through the steps in this embodiment, a plurality of videos are determined as the third video and are cached, when the user frequently performs sliding operation to switch videos, it is still ensured that the video data are locally cached in the terminal device, and thus the play pause problem is further avoided.
And step S208, acquiring the video buffer amount, and caching the third video based on the video buffer amount to generate a cached video.
Illustratively, the video buffer amount is information for characterizing the amount of data for buffering the third video, e.g., the video buffer amount may be a percentage value, e.g., 50%; it may also be a specific data size, for example 2048kB (kilobyte). By setting the video buffering amount, when the third video is buffered, only part of stream data in the third video is buffered, so that the preliminary buffering of the third video can be realized, and then when the third video is determined to be played, the rest stream data of the third video is continuously buffered, so that the video blockage is avoided, and the flow waste caused by the buffering of all the third videos is avoided.
In one possible implementation, obtaining the video buffer amount includes:
acquiring content information of a first video, wherein the content information represents a video content category of the first video; and determining the video caching amount according to the content information of the first video and the playing time length of the first video.
Illustratively, the content information is information characterizing a video content category of the first video, such as: a fun video, a movie video, a learning video, etc. The content video may be determined by the description information of the first video, such as the category label, the video name, the video author identification, and the like. The user is interested in different video contents. For videos that are of interest to the user, the user may watch for a long time, while for videos that are not of interest to the user, the user may quickly switch to the next video. Therefore, for the cached third video, if the user is not interested in the third video to be played, it is likely that the user will switch the third video to the next video soon, and thus the user may not be interested in playing the third video. And determining a video buffer amount according to the content information of the first video and the playing time of the first video, and performing a small amount of buffer on the third video according to the video buffer amount, so that the network bandwidth and the flow can be saved.
In another possible implementation, obtaining the video buffer amount includes: and determining the video buffer amount according to the confidence value of the sliding direction corresponding to the second sliding operation after the first sliding operation.
For example, the sliding direction corresponding to the second sliding operation and the playing direction corresponding to the second sliding operation have a fixed mapping relationship, and the greater the confidence value of the sliding direction corresponding to the second sliding operation predicted by the sliding prediction model is, the greater the possibility that the video buffering direction is the same as the playing direction corresponding to the second sliding operation is, and conversely, the less the possibility that the video buffering direction is the same as the playing direction corresponding to the second sliding operation is. Determining a corresponding video buffer amount according to the confidence value of the sliding direction predicted by the sliding prediction model, matching the video buffer amount with the possibility that the video buffer direction is the same as the playing direction corresponding to the second sliding operation, and caching a third video by using the smaller video buffer amount when the possibility that the video buffer direction is the same as the playing direction corresponding to the second sliding operation is smaller; otherwise, the third video is cached by using a larger video caching amount, so that the bandwidth utilization rate is further improved, and the flow is saved. Fig. 7 is a schematic diagram of a correspondence relationship between a confidence value of a sliding direction corresponding to a second sliding operation and a video cache amount according to an embodiment of the present disclosure, and as shown in fig. 7, when the confidence value of the sliding direction corresponding to the second sliding operation predicted by a sliding prediction model is 0.8, a data amount of video caching for a third video is 2048kB, and a cache file with a size of 2048kB is generated; when the confidence value of the sliding direction corresponding to the second sliding operation predicted by the sliding prediction model is 0.9, the data size of video caching for the third video is 4096kB, and a cache file with the size of 4096kB is generated.
In step S209, in response to the second sliding operation for the second video, if the playing direction corresponding to the second sliding operation is the same as the playing direction corresponding to the video caching direction, the cached video is played.
