Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Referring to fig. 1, fig. 1 is a diagram illustrating an application environment for adjusting a play duration of a video frame according to an exemplary embodiment, where the application environment may include a client 01 and a cloud platform 02.

The cloud platform 02 may include a duration adjustment module, a cloud game module, and a library file (e.g., libc. The library file includes a time acquisition function. Alternatively, the cloud platform may be a cloud host including any operating system type that supports cloud gaming. Optionally, the cloud platform may include, but is not limited to: the cloud host is constructed based on a Linux system, the cloud host is constructed based on a Windows system, the cloud host is constructed based on an Andriod system (android system), the cloud host is constructed based on an iOS system and the like.

The time length adjusting module can be used for hooking a time obtaining function in a library file in advance, receiving a playing time length adjusting request carrying playing time length adjusting information of a video frame in a cloud game, obtaining a target playing time length of the video frame according to the initial playing time length and the playing time length adjusting information of the video frame, responding to the time obtaining request triggered by the cloud game module in the cloud platform, and returning the target playing time length to the cloud game module.

The cloud game module can be used for receiving the target playing time length returned by the time length adjusting module.

The client 01 may be configured to send a play duration adjustment request of a video frame in the cloud game to a duration adjustment module in the cloud platform 02. Alternatively, the client 01 may be a player game terminal held by a user, the player game terminal is used for starting a cloud game, and the player game terminal may include a terminal device such as a smartphone, a desktop computer, a tablet computer, a notebook computer, a digital assistant, an Augmented Reality (AR)/Virtual Reality (VR) device, and a smart wearable device.

It should be noted that the above application environment is only an example, and the embodiments of the present disclosure may also include other application environments.

Fig. 2 is a schematic diagram illustrating a networking architecture of a cloud game according to an example embodiment. As shown in fig. 2, an Application (APP) runs on a client 01, and a cloud game runs on a cloud platform, which may communicate over a network.

The control flow is used for representing game operation instructions (such as instructions triggered by various click operations in a game) for controlling a cloud game on the cloud platform by operating an APP on a user terminal by a user, and can also be used for representing business instructions (such as instructions triggered by login, payment and the like) related to the cloud game between the APP and the cloud game.

And the audio and video stream is used for indicating that the cloud platform can send the audio and video stream of the cloud game to the APP on the client, and the APP is used for displaying a game picture corresponding to the audio and video stream to the user so that the user can further execute game operation to play the game based on the displayed game picture.

Fig. 3 is a flowchart illustrating a method for adjusting a playing time length of a video frame according to an exemplary embodiment, where the method is applied to the time length adjusting module in fig. 1, and may include the following steps.

In step S11, a play time length adjustment request of a video frame in a cloud game is received; the playing time length adjusting request carries the playing time length adjusting information of the video frame.

Illustratively, the duration adjustment module may be a process for adjusting the playing duration in the cloud platform.

In particular, the cloud game may include any type of cloud game. Such as a stand-alone game, a multiplayer online game, etc. The plurality of persons may refer to at least two persons.

Optionally, the video frame corresponds to a cloud game running in the cloud platform, and the video frame may be any game frame in a cloud game video, that is, any playing picture in the cloud game video.

Specifically, the playing duration of a video frame refers to: the time required for playing the video frame can also be understood as the interval time between two picture switches (i.e. the time required for updating each video frame).

For example, in the process of participating in the game, if the playing time of the video frame in the game video is to be adjusted, the video frame in the cloud game video displayed in the client may be clicked and the like, so as to send the playing time adjustment request to the time adjustment module in the cloud platform. Optionally, the playing time length adjustment information may include, but is not limited to: the playing time of the video frame is prolonged, the playing time of the video frame is shortened, the playing of the preset content in the video frame is skipped, and the like.

In practical applications, most mobile phone games develop games by using two major engines (a Cocos2D engine and a Unity3D engine), and the two major engines calculate the playing time of each frame of the game (i.e. the time required for updating each frame) by using a fixed library file function. For example, the Cocos2D engine computes the updates per frame through the gettimeoffday function in the library file, and the Unity3D engine computes the updates per frame by calling clock _ gettime in the library file.

Optionally, the duration adjustment module may perform hooking processing on the time obtaining function in the library file in advance. The time acquisition function may include the gettimeoffday function described above, clock _ gettime, and the like.

In step S13, a target playing time length of the video frame is obtained according to the initial playing time length of the video frame and the playing time length adjustment information.

Specifically, the initial play duration of a video frame refers to: the preset time that is preset by the cloud platform and is required for playing the video frame may also be understood as a preset interval time for switching between two pictures (i.e., a preset time that is required for updating each video frame). The cloud game video generally includes a plurality of video frames, and the initial playing time of each video frame may be the same or different.

In the embodiment of the present disclosure, the initial playing time of the video frame is preset, and the time length adjusting module may obtain the preset initial playing time, and calculate the target playing time length of the video frame according to the initial playing time length of the video frame and the playing time length adjusting information.

It should be noted that, the initial playing time length of each video frame in the cloud game video may be the same or different. Under the condition that the initial playing time length of each video frame is the same, the target playing time length calculated by the time length adjusting module is suitable for all the video frames. For example, the game picture currently being watched by the user is a video frame a, if the user triggers a play duration adjustment request at this time, the duration adjustment module obtains an initial play duration of the video frame a (which is equivalent to obtaining the initial play duration of each video frame), and obtains a target play duration of the video frame a (which is equivalent to obtaining the target play duration of each video frame) according to the initial play duration and the play duration adjustment information of the video frame a.

And under the condition that the initial playing time length of each video frame is different, the target playing time length calculated by the time length adjusting module is suitable for each video frame. In this case, the duration adjustment module needs to obtain the initial playing duration of each video frame in real time, and calculate the target playing duration of each video frame according to the initial playing duration and the playing duration adjustment information. For example, the game picture currently watched by the user is a video frame a, and if the user triggers a play duration adjustment request at this time, the duration adjustment module first obtains an initial play duration of the video frame a, and obtains a target play duration of the video frame a according to the initial play duration and play duration adjustment information of the video frame a. When the game picture is switched from the video frame a to the next video frame (for example, the video frame B), the duration adjustment module may continue to obtain the initial playing duration of the video frame B, and obtain the target playing duration of the video frame B according to the initial playing duration and the playing duration adjustment information of the video frame B, and so on, thereby obtaining the target playing duration of each video frame.

In step S15, in response to a time acquisition request triggered by a cloud game module in the cloud platform, returning the target playing duration to the cloud game module; the cloud game module corresponds to the cloud game.

Specifically, the cloud game module may be a cloud game process in the cloud platform that controls the operation of the cloud game.

In the embodiment of the disclosure, the cloud game module can call the time obtaining function in the library file in real time, and when the time obtaining function is called, the time obtaining request is triggered. Since the time obtaining function is hooked in advance by the time length adjusting module, when the time obtaining function is called, the time length adjusting module can intercept the time length adjusting module, so that the target playing time length is returned to the cloud game module in response to the time obtaining request.

In the embodiment of the disclosure, when receiving a play duration adjustment request carrying play duration adjustment information of a video frame, a duration adjustment module may obtain a target play duration of the video frame according to an initial play duration and the play duration adjustment information of the video frame, and when responding to a time acquisition request triggered by a cloud game module in a cloud platform, return the target play duration to the cloud game module, where the target play duration returned to the cloud game module is different from the initial play duration, that is, change the play duration of the video frame (increase the play duration or shorten the play duration), thereby enabling acceleration or deceleration of the video frame and improving game experience of a user.

In an exemplary embodiment, the play-time adjustment information represents: increasing or shortening the initial playing time of the video frame by a preset number times; the obtaining the target playing duration of the video frame according to the initial playing duration of the video frame and the playing duration adjustment information may include:

Optionally, when the video frame is a cut-in animation, a leader animation, or the like of the cloud game, the user has a need to accelerate playing of the animation, so that time is saved. The user clicks the 'speed-doubling playing' button at the client to display a speed selection box for clicking the speed in the speed selection box, so as to trigger the playing time length adjustment information for shortening the initial playing time of the video frame by a preset time.

The cut scene is a part of the game, when the cut scene is displayed, a player generally cannot actively control the game (or has little control right), and the cut scene is often used for interrupting the current game, developing a story line, displaying the development of a character, or providing background information, environment atmosphere, conversation and clues. The cut scene may be in the form of animation, or may be an actual movie picture.

The leader animation refers to a plurality of animations which are played before the game is played and used for popularizing the brand of a game manufacturer.

Fig. 4 is a diagram illustrating a method for shortening an initial play time of a video frame by a preset number times according to an exemplary embodiment. As shown in fig. 4, when the video frame is a cut scene, a "double speed play" button may be displayed, and a user clicks the "double speed play" button at the client to display a speed selection box. Assuming that the user selects "2X" in the speed selection box, it indicates that the initial play time period of the cutscene needs to be shortened by 2 times. At this time, the time length adjusting module can calculate the ratio of the initial playing time length (assumed to be 5s) of the cut scene animation to the speed multiple speed selected by the user, and obtain the target playing time length of the cut scene animation to be 2.5s, so that the playing time of the cut scene animation is shortened, the acceleration of the cut scene animation is realized, the user can experience the plot content of the game in less time, and the game experience of the user is improved.

Alternatively, when the game rhythm in the cloud game is too fast, the user may not be able to fully draw the game content, or for a difficult game, the user may wish to slow down the game screen in order to easily pass through the level of the game. Therefore, when the video frame is the game picture, the 'one-key deceleration' button can be displayed in the cloud game. The user clicks the 'one-click speed reduction' button at the client to display a speed selection box for clicking the speed in the speed selection box, so as to trigger the change of the initial playing time of the video frame to the preset time of the playing duration adjustment information.

For example, when the user clicks the "speed play" button on the client, the speed selection box may not be displayed, and the initial play time of the game animation may be shortened by a preset number times by default.

Fig. 5 is a diagram illustrating an increase in an initial play-out time length of a video frame by a preset number times according to an exemplary embodiment. As shown in fig. 5, when a video frame is a game picture with high difficulty, a "one-click speed reduction" button can be displayed, and a user clicks the "one-click speed reduction" button at a client, so that the initial playing time of the game animation can be increased by a preset number of times by default, the playing time of the game animation is prolonged, the speed reduction of the game animation is realized, the speed of the whole game is slowed, more obstacle response time is provided for a player, the user can smoothly pass through a game stage, and the game experience of the user is improved.

Illustratively, when the user clicks the "speed-down by one button" button on the client, the speed-down selection box may be displayed, and if the user selects "2X" on the speed-down selection box, it indicates that the initial play time of the video frame needs to be increased by a preset number times (for example, 2 times). At this time, the duration adjustment module may calculate a product of the initial playing duration (assumed to be 5s) of the cut scene and the playing duration adjustment information, so as to obtain a target playing duration of the cut scene as 10 s.

Optionally, when the user clicks the "speed reduction by one key" button at the client, the speed reduction selection box may be displayed, and if the user selects "2X" in the speed reduction selection box, it indicates that the initial playing time of the video frame needs to be increased by 2 times.

In the embodiment of the disclosure, when the representation of the playing duration adjustment information increases or shortens the initial playing duration of the video frame by a preset number times, the multiplication and division operation is performed on the initial playing duration and the playing duration adjustment information to obtain the target playing duration, which not only can improve the precision of calculating the target playing duration, but also can calculate the target playing duration according to the playing duration adjustment information carried in the playing duration adjustment request triggered by the user at the client, so that the determination of the target playing duration can meet the actual requirement of the user, so that the user can experience the scenario content of the game in less time or slow down the speed of the whole game, give more obstacle response time to the user, and improve the game experience of the user.

In an exemplary embodiment, the play-time adjustment information represents: skipping playing of preset content in the video frame; the obtaining the target playing time length of the video frame according to the initial playing time length of the video frame and the playing time length adjustment information includes:

calculating the difference value between the initial playing time length and the preset time to obtain the target playing time length; the preset time is the time required for playing the preset content

Optionally, in the case that the video frame is any video frame in the cloud game video, the preset content may be a part of or all of the content in any video. At this time, the difference between the initial playing time and the preset time required for playing the preset content may be used as the target playing time of the video frame.

Optionally, in a case where the video frames are a plurality of video frames in the cloud game video, the preset content may be a part of or all of the content in the plurality of videos. At this time, the sum of the initial playing times corresponding to the plurality of video frames and the difference between the preset times required for playing the preset contents in the plurality of videos may be used as the target playing times corresponding to the plurality of video frames.

Illustratively, when the video frame is a live animation, a leader animation, a battle round picture (a long waiting time exists in the battle round, and many battle processes belong to full-automatic battles without user operation, and the user needs to watch a uniform battle animation at the moment and can receive a reward after the battle is finished), and the like, the "one-key skip" button can be displayed in the cloud game, and when the user clicks the "one-key skip" button at the client, the play duration adjustment request can be triggered, so that the play of the preset content is skipped.

Fig. 6 is a diagram illustrating a skipping of preset content in a video frame according to an example embodiment. As shown in fig. 6, when the video frame is a battle turn picture, a "one-click skip" button may be displayed, and the user clicks the "one-click skip" button at the client, so that the button may skip playing of the preset content, thereby accelerating the battle process and getting rewards faster. At this time, the duration adjustment module may calculate a difference between an initial playing duration (assumed to be 10s) of the battle round picture and a preset time (for example, 5s) required for playing the preset content, and obtain a target playing duration of the battle round picture as 5s, so that the playing duration of the battle round picture is shortened, skipping of the preset content in the battle round picture is realized, a user does not need to watch a uniform battle animation, rewards are received more quickly, and user game experience is improved.

Continuing with fig. 4, a "skip by one key" button may also be displayed in the scene of passage, and the user may skip playing the preset content by clicking the "skip by one key" button at the client, so that the user may experience the plot content of the game in less time.

In the embodiment of the present disclosure, in the representation of the playing duration adjustment information: when the playing of the preset content in the video frame is skipped, the difference between the initial playing time and the preset time required for playing the preset content can be calculated to obtain the target playing time. The target playing time length calculation method has the advantages that the target playing time length calculation precision can be improved, the target playing time length can be obtained through calculation according to the playing time length adjustment information carried in the playing time length adjustment request triggered by the user at the client, the target playing time length can be determined to meet the actual requirements of the user, the user can skip the uninteresting content, the user time is saved, and the user experience is improved.

In an optional embodiment, before the receiving the request for adjusting the playing time length of the video frame, the method further includes:

and hooking the time acquisition function in an inline hook mode.

In the embodiment of the disclosure, the time acquisition function in the library file can be hooked by an Inline Hook (Hook), and the Inline Hook can modify an instruction in the time acquisition function to change the return time of the time acquisition function, so that the playing duration of the video frame is changed, and the acceleration or deceleration of the game can be realized.

Fig. 7 is a flowchart illustrating a process of returning the target play duration to the cloud game module in response to a time acquisition request triggered by the cloud game module in the cloud platform according to an exemplary embodiment. As shown in fig. 7, in the step S15, the returning the target playing time length to the cloud game module in response to the time obtaining request triggered by the cloud game module in the cloud platform may include:

in step S1501, the time acquisition function is intercepted in response to the time acquisition request triggered by the cloud game module calling the time acquisition function.

In step S1503, jump is made to the head address of the time acquisition function.

In step S1505, the command in the first address is updated based on the target playing time length, and an updated time obtaining function is obtained.

In step S1507, returning the updated time acquisition function to the cloud game module; the cloud game module is used for acquiring the target playing time length from the updated time acquisition function.

For example, the instruction in the update header address may be an instruction in the modify header address, that is, an instruction in the header address is overwritten by the target play time length.

Specifically, the cloud game module may call a time obtaining function in the library in real time, and trigger a time obtaining request, and the library file may forward the event obtaining request to the duration adjustment module. Since the time length adjusting module has previously hook the time obtaining function, the time length adjusting module may intercept the time obtaining function in response to the time obtaining request, and jump to the first address of the time obtaining function. And the time length adjusting module modifies the first instruction in the first address by using the calculated target playing time length so as to obtain an updated time obtaining function. After the update is completed, the time length adjusting module returns the updated time obtaining function to the cloud game module, and the cloud game module can obtain the target playing time length from the time obtaining function.

In the embodiment of the disclosure, the target playing time is inserted into the time obtaining function to change the returning time of the time obtaining function, so that the playing duration of the video frame is changed, and further, the acceleration or deceleration of the game can be realized.

In a possible embodiment, in the step S11, the receiving a play time length adjustment request of a video frame in a cloud game may include:

and receiving the play time length adjustment request sent by the client.

Correspondingly, the method may further include:

responding to the time acquisition request, and returning the target playing time length to the cloud game module; the cloud game module is used for adjusting the playing speed of the video frame according to the target playing duration and sending the video frame with the adjusted speed to the client.

And the client is used for playing the video frame after the speed adjustment.

Specifically, after the cloud game module obtains the target playing time, the playing speed of the video frame can be adjusted through the target playing time, and the video with the speed being jumped to is sent to the client, so that the client plays the video with the speed adjusted. For example, if the target playing time is 2 times the initial playing time, the playing speed of the video frame is reduced by 2 times.

In the embodiment of the present disclosure, the video frame with the adjusted speed may be issued to the client according to the play duration adjustment request triggered by the client, and played by the client. The acceleration or one-key skipping of the video frames can accelerate the progress of the game, reduce the waiting feeling of the user and improve the game experience; the video frame is decelerated, so that the game progress can be slowed down, the challenge difficulty of the game is reduced, the user can smoothly pass the game without the condition of 'card closing', and the user can experience more game contents conveniently.

In the following, the method for adjusting the playing time of a video frame is introduced by taking the example of accelerating the video frame at double speed, the game engine is a Unity engine, and the time obtaining function is clock _ gettime:

fig. 8 is a flowchart illustrating another method for adjusting a play-time duration of a video frame according to an example embodiment. As shown in fig. 8, the method comprises the following steps:

in step S201, when the cloud platform is started, the duration adjustment module is automatically pulled up, and the duration adjustment module performs a clock _ gettime method from Hook to libc.

In step S203, after the user clicks and starts speed-doubling acceleration at the client, a play duration adjustment request carrying play duration adjustment information is triggered (the play duration adjustment information represents that the play duration of a video frame is shortened by a preset number of times), the client transmits the play duration adjustment request to a duration adjustment module, the duration adjustment module records the speed-doubling acceleration inside, and calculates a target play duration of the video frame (i.e., a time required to update the video frame) according to the initial play duration of the video frame and the play duration adjustment information.

In step S205, the cloud game module calls clock _ gettime in libc.

So forwards the time acquisition request to the duration adjustment module in step S207. Because the time length adjusting module is used for intercepting the time acquisition request in advance by a clock _ gettime method from Hook to libc.

In step S209, the duration adjustment module returns the clock _ gettime method with the modified head address to the cloud game module, where a first instruction in the head address of the modified clock _ gettime method is the calculated target playing duration.

In step S2011, the cloud game module executes the first instruction in the first address to increase the speed of the video frame according to the target playing time length.

In step S2013, the cloud game module compresses the accelerated video frames and transmits the compressed video frames to the client.
