[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0030] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this disclosure are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0031] The following explains the application scenarios of the embodiments of the present disclosure:

[0032] Figure 1 is an application scenario diagram of the interface switching method provided by an embodiment of the present disclosure. The interface switching method provided by an embodiment of the present disclosure can be applied to the scenario of entering and exiting the live broadcast room in an application. More specifically, the interface switching method provided by this embodiment can be applied to the application scenario of entering and exiting the live broadcast room in an application based on the Android operating system. As shown in Figure 1, the method provided by an embodiment of the present disclosure can be applied to a terminal device, such as a smart phone, on which applications such as live broadcast and video are running. In the process of the terminal device running the above-mentioned application, a preview interface 11 of the target live broadcast room will be displayed in the main interface of the application, and a preview video 12 of the target live broadcast room will be played through the preview interface 11. Afterwards, when the user clicks on the preview interface 11, the terminal device jumps from the main interface of the application to the live broadcast room interface of the target live broadcast room, and plays the live video 13 in the live broadcast room interface of the target live broadcast room, thereby realizing the process of entering the live broadcast room interface from the preview interface in the main interface of the application. Similarly, when the user enters the exit command (for example, clicking the exit control in the live broadcast room interface), the terminal device returns from the live broadcast room interface to the main interface of the application, and can continue to play the preview interface of the target live broadcast room through the preview interface located in the main interface, thereby realizing seamless switching between the preview interface in the main interface and the live broadcast room interface, and realizing smooth entry and exit of the live broadcast room.

[0033] However, in actual use, taking the Android operating system as an example, to display the preview interface of the live broadcast room in the main interface of the application, it is necessary to activate the drawing surface view (SurfaceView) corresponding to the preview interface, then cache the image data of the preview video corresponding to the target live broadcast room in the screen image cache corresponding to the drawing surface view, and use the drawing surface (Surface) as a handle to access the screen image cache, thereby realizing the image drawing of the preview video; and after entering the live broadcast room interface, it is necessary to close the drawing surface view corresponding to the preview interface and destroy the screen image cache in the drawing surface view corresponding to the preview interface. Then, the drawing surface view corresponding to the live broadcast room interface is activated again, and the image data of the live broadcast video corresponding to the target live broadcast room is cached in the screen image cache corresponding to the drawing surface view and drawn. The above process is executed by the main thread (UI thread) of the application, that is, the main thread needs to "switch" between the two drawing surface views, but this "switching" process is time-consuming. Due to the time-consuming "switching" process, the existing solutions in the art will experience black screen and freezes when entering the live broadcast room interface from the preview interface, affecting the smoothness of entering and exiting the live broadcast room. The embodiments of the present disclosure provide an interface switching method to solve the above problems.

[0034] Referring to FIG2 , FIG2 is a flow chart of the interface switching method provided in an embodiment of the present disclosure. The method of this embodiment can be applied in a terminal device, and the interface switching method includes:

[0035] Step S101: Play the preview video of the target live broadcast room in the first interface, and pull the live broadcast stream data of the target live broadcast room when a trigger instruction for the preview video is received.

[0036] Exemplarily, referring to the application scenario diagram shown in FIG1 , the execution subject of the interface switching method provided in this embodiment can be a terminal device, such as a smart phone. A target application is installed in the terminal device, and the target application is, for example, a live broadcast software client, a video software client, etc. The interface switching method provided in this embodiment can be stored in the target application in the form of program code or functional modules. When the terminal device runs the above-mentioned target application, it executes the interface switching solution provided in this embodiment. More specifically, the method provided in this embodiment is applied to the application scenario of entering the live broadcast room interface.

[0037] Specifically, after running the target application, the terminal device displays the first interface. The first interface can be the main interface or the lower-level functional interface of the target application, or it can be the video preview interface for playing videos in the main interface or the lower-level functional interface of the target application. The terminal device plays the preview video of the target live broadcast room through the first interface. The preview video has the same content as the live video currently playing in the target live broadcast room, and the video playback progress can be the same or delayed. The preview video and the live video played in the target live broadcast room are generated based on the same live stream data, that is, after decoding and rendering the live stream data of the target live broadcast room, the preview video is generated and played in the first interface. Since the role of the preview video is to provide the user with a preview of the live broadcast room content while displaying the content in the main interface and the lower-level functional interface of the target application, the preview video usually has a lower bit rate and resolution than the live video in the live broadcast room, or only displays images without playing sound. Of course, the preview video can also be exactly the same as the live video in the live broadcast room as needed, which is not specifically limited here. The first interface in this embodiment implements the playback function of the preview video of the target live broadcast room based on the corresponding video playback component. Before playing the preview video of the target live broadcast, it also includes the initialization of the video playback component, obtaining the video stream of the target live broadcast room, and image rendering and caching steps. The specific implementation method of playing the preview video of the target live broadcast room in the first interface will not be repeated here.

[0038] Furthermore, after the preview video of the target live broadcast room is displayed, if the user is interested in the live broadcast content of the target live broadcast room based on the preview video, the user will trigger the interface jump by clicking or other operations, that is, input a trigger instruction for the preview video, so that the terminal device jumps to the live broadcast room interface corresponding to the target live broadcast room. Specifically, when the terminal device receives the trigger instruction for the preview video, it first pulls the live broadcast stream data of the target live broadcast room to perform a subsequent screenshot process based on the live broadcast stream data. Among them, since the preview video of the target live broadcast room itself requires the corresponding live broadcast stream data to be played, in a possible implementation method, the terminal device always continuously obtains the live broadcast stream data of the target live broadcast room. Pulling the live broadcast stream data of the target live broadcast room means that when the terminal device receives the trigger instruction for the preview video, it obtains the latest acquired live broadcast stream data based on the identifier of the target live broadcast room, and performs a subsequent screenshot process based on the latest acquired live broadcast stream data.

[0039] Step S102: Obtain a target frame image of the target live broadcast room through the live broadcast stream data of the target live broadcast room.

[0040] Exemplarily, after obtaining the live streaming data of the target live broadcast room, the live streaming data is processed, that is, the live streaming data is rendered into corresponding image frames and intercepted, and the latest image frame obtained therein is obtained, that is, the target frame image. Among them, the live streaming data is decoded and rendered into a screen image cache, and accessed through a drawing surface (Surface). The specific implementation process is a prior art and will not be repeated here. After obtaining the screen image cache, in a possible implementation method, the image interception of the live streaming data is implemented through a target function built into the target application, thereby obtaining the current frame screenshot. Specifically, the target function is a custom screenshot function, which includes a pixel copy (PixelCopy) function. Among them, the pixel copy function can be called a pixel copy (PixelCopy) interface, which is an official API interface provided by the Android system. Through the pixel copy interface, with the drawing surface (Surface) as the input parameter, a screenshot of the screen image cache can be implemented, that is, a screenshot rendered for SurfaceView, that is, the target frame image, and its corresponding data format is a bitmap (bitmap). More specifically, the pixel copy function is implemented by passing the message handler object corresponding to the main thread and using the message handler object to post a callback message to execute the corresponding screenshot function. The specific implementation method of the pixel copy function is existing in the art and will not be detailed here.

[0041] Step S103: Display the target frame image in the second interface until the live video of the target live broadcast room is loaded, and then play the live video of the target live broadcast room in the second interface.

[0042] For example, because the terminal device responds to the trigger instruction and jumps to the second interface, it is necessary to rebuild the loading screen image cache on the second interface to realize the display of the image content in the drawing surface view, that is, there is a "gap period" after the first interface disappears and before the live video is played on the second interface, which leads to the visual appearance of a "black screen". Before the second interface of the target application completes loading the screen image cache, that is, before the live video of the target live broadcast room is loaded, the content of the live video cannot be displayed in the second interface. Therefore, the target frame image obtained in the previous step is temporarily displayed in the second interface, so that the second interface visually displays the content of the live video, avoiding the visual effect of a black screen. Until the second interface completes loading the screen image cache, the live video of the corresponding target live broadcast room is played on the second interface, realizing the process of switching from the first interface to the second interface.

[0043] Figure 3 is a schematic diagram of a process of switching from a first interface of a target application to a second interface provided by an embodiment of the present disclosure. As shown in Figure 3, in the main interface of the target application, a first interface is displayed based on a live broadcast control, and a preview video of the target live broadcast room is played in the first interface; after the user clicks on the first interface, the terminal device first jumps to the second interface, that is, the live broadcast room interface of the target live broadcast room, and displays the target frame image obtained through the live broadcast stream data of the target live broadcast room in the second interface, and at the same time loads the screen image cache of the target live broadcast room (shown in the figure as loading the screen image cache), until the screen image cache is loaded, and then the live video of the target live broadcast room starts to be played in the second interface, thereby completing the process of switching from the first interface to the second interface.

[0044] In this embodiment, the preview video of the target live broadcast room is played in the first interface, and upon receiving a trigger instruction for the preview video, the live stream data of the target live broadcast room is pulled; the target frame image of the target live broadcast room is obtained through the live stream data of the target live broadcast room; the target frame image is displayed in the second interface of the target application until the live video of the target live broadcast room is loaded, and then the live video of the target live broadcast room is played in the second interface. In the process of jumping from the first interface where the preview video is located to the second interface where the live video is located, the corresponding target frame image is obtained through the live stream data, and the target frame image is displayed before the screen image cache is loaded in the second interface, thereby avoiding a black screen during the jump from the first interface to the second interface and increasing the smoothness of the interface switching process.

[0045] Referring to FIG4 , FIG4 is a second flow chart of the interface switching method provided by the embodiment of the present disclosure. Based on the embodiment shown in FIG2 , this embodiment further refines the process of obtaining the target frame image. The interface switching method includes:

[0046] Step S201: creating a first drawing surface in a first interface of a target application.

[0047] Step S202: downsample the live streaming data of the target live broadcast room to generate downsampled video data.

[0048] Step S203: Draw the downsampled video data on the first drawing surface to play the preview video of the target live broadcast room.

[0049] Exemplarily, after the target application is run, a first drawing surface is first created for the first interface for playing the preview video of the target live broadcast room. Specifically, the first drawing surface may refer to an object of a drawing surface view (SurfaceView object) located in the first interface. The process of creating and initializing SurfaceView is a prior art known to those skilled in the art and will not be described in detail here. Afterwards, the acquired live stream data of the target live broadcast room is downsampled, for example, by reducing the image resolution, frame rate, or bit rate, to generate data suitable for video preview, i.e., downsampled video data. Afterwards, based on the specific implementation method of SurfaceView, the downsampled video data is drawn, and the drawn image is displayed in the preview interface, thereby realizing the playback of the preview video of the target live broadcast room.

[0050] Step S204: When a trigger instruction for previewing the video is received, the live streaming data of the target live broadcast room is pulled, and a second drawing surface is created in the second interface of the target application.

[0051] Step S205: Create a renderer object through the main thread of the target application.

[0052] Step S206: Execute the target function through the renderer object to process the live stream data and obtain the target frame image. The target function includes a pixel copy function, which receives the rewritten target method to immediately generate the target frame image.

[0053] For example, when the terminal device receives a trigger instruction for the preview video, it triggers a jump to the live broadcast room interface, that is, the second interface. First, the second interface of the target application is started, and a second drawing surface is created in the second interface. The second drawing surface is similar to the first drawing surface, and both are objects of the drawing surface view (SurfaceView object). This process can be executed by the main thread of the target application, and the specific process steps are not repeated.

[0054] Afterwards, a renderer object (ThreadedRenderer) is created through the main thread of the target application, and the renderer object executes the corresponding target function to process the live stream data to obtain the target frame image. The target function is a custom function built into the target application, and the target function includes a pixel copy (PixelCopy) function. Through the pixel copy interface, with the drawing surface (Surface) as the input parameter, a screenshot of the screen image cache can be achieved, that is, a screenshot of the SurfaceView rendering, so as to obtain the target frame image. The data format corresponding to the target frame image is a bitmap. More specifically, the pixel copy function is implemented by passing in the message handler object (handler) corresponding to the main thread, and using the message handler object to make a callback message (post) to execute the corresponding screenshot function.

[0055] In the related art, in order to realize the screenshot of the drawing surface view (SurfaceView) through the pixel copy function, it is necessary to use the message handler object (handler) of the main thread as an input parameter, and use the message handler object to make a callback message (post) to realize the screenshot function. However, in the scenario of entering and exiting the live broadcast room, many complex and time-consuming logics and tasks need to be executed by the main thread. Therefore, the execution time of the callback message (post) becomes longer and cannot be controlled. This further leads to a delay in the implementation of the screenshot function. In the process of switching the target application from the first interface to the second interface, if the screenshot function is delayed, it will lead to the inability to generate and display the target frame image in time, and the black screen state cannot be blocked in time, resulting in problems such as freeze and reduced fluency, affecting the user experience.

[0056] In response to the above problem, in this embodiment, the target function includes a pixel copy function, and the pixel copy function realizes the immediate generation of the target frame image by receiving the overridden target method. Among them, the target method is, for example, a specific time message sending method (sendMessageAtTime method). By re-using the specific time message sending method, the screenshot function can be executed immediately, even if the execution message (runnable) in the callback message is executed immediately, without the need to execute the screenshot function through the message queue (MessageQueue) as in the solution in the related art, thereby avoiding the above-mentioned callback message (post) The execution time becomes longer and uncontrollable problem, so that the target frame image can be generated in time, and the black screen state in the process of switching from the first interface to the second interface is blocked.

[0057] FIG5 is a schematic diagram of a process for generating a target frame image provided by an embodiment of the present disclosure. As shown in FIG5 , in related art, the process for generating a target frame image includes:

[0058] S01. Execute ThreadedRenderer.copySurfaceInto.

[0059] S02. Execute listenerThread.post.

[0060] S03. Execute sendMessageDelayed.

[0061] S04. Execute sendMessageAtTime.

[0062] S05. Execute enqueueMessage.

[0063] S06. Execute the runnable through the message queue to generate a target frame image.

[0064] Among them, ThreadedRenderer is the renderer object, and copySurfaceInto is the target function. Furthermore, in the target function, listenerThread.post is called, listenerThread is the daemon thread, and post is the callback message. Furthermore, in the callback message, the sendMessageDelayed function is called, and sendMessageDelayed is a delayed sending function (interface). Through this delayed sending function, the execution message is inserted into the specified delayed position in the message queue. Furthermore, the delayed sending function is based on the sendMessageAtTime function, that is, the specific moment message sending method is implemented. The specific moment message sending method is used to send messages at a determined time. Afterwards, the enqueueMessage function in the sendMessageAtTime function is called. The enqueueMessage function is used to insert messages. Through the enqueueMessage function, the runnable (execution message) is inserted into the message queue and waits for execution. Finally, when the message queue executes runnable, the screenshot function is executed to generate the target frame image.

[0065] FIG6 is a schematic diagram of another process of generating a target frame image provided by an embodiment of the present disclosure. As shown in FIG5 , in this embodiment, the process of generating a target frame image includes:

[0066] S01. Execute ThreadedRenderer.copySurfaceInto.

[0067] S02. Execute listenerThread.post.

[0068] S03. Execute sendMessageDelayed.

[0069] S14. Execute the rewritten sendMessageAtTime.

[0070] S15. Execute runnable to generate a target frame image.

[0071] For example, in combination with the process diagram shown in reference Figure 5, after executing the same steps S01-S03, the rewritten sendMessageAtTime is executed, and the runnable is directly executed in sendMessageAtTime to immediately generate the target frame image without entering the message queue to wait, thereby avoiding the problems of excessively long time and uncontrollable time consumption in generating the target frame image in the above-mentioned related technologies.

[0072] In a possible implementation, as shown in FIG7 , a specific implementation of step S206 includes:

[0073] Step S2061: calling the drawing surface access interface to obtain the screen image cache based on the drawing surface view corresponding to the live stream data.

[0074] Step S2062: Taking the screen image cache and the specific moment message sending method of the message processor object as input, the pixel copy function is called to generate the target frame image, wherein the specific moment message sending method of the message processor object is overwritten, and the specific moment message sending method is used to immediately execute the execution message corresponding to the pixel copy function.

[0075] Exemplarily, the drawing surface view is surfaceView, and the screen image cache based on the drawing surface view is the cached image rendered by surfaceView. The drawing surface access interface is surfaceHolder, which stores a reference to the Surface object. Through the drawing surface access interface, the screen image cache corresponding to the Surface can be obtained and accessed. That is, the screen image cache is obtained through surfaceHolder, and the specific implementation method is to obtain the screen image cache by calling surfaceHolder.surface. Afterwards, the above-mentioned screen image cache and the specific moment message sending method are input, and the pixel copy function (PixelCopy.request) is called. Among them, the specific moment message sending method of the message processor object is overridden, and the specific moment message sending method is used to immediately execute the execution message corresponding to the pixel copy function. Among them, exemplarily, the overriding method of the specific moment message sending function includes:

[0076] override fun sendMessageAtTime(msg:Message?,uptimeMillis:Long

[0077] msg?.callback?.run()

[0078] return true)

[0079] The rewritten specific moment message sending function implemented by the above exemplary code implementation method can realize the immediate execution of the execution message corresponding to the pixel copy function, thereby achieving the purpose of generating the target frame image. The code implementation in the above code lines complies with the development language (such as Java) specifications for developing Android applications, and the specific meanings are not repeated one by one. At the same time, it should be noted that the rewritten specific moment message sending function can also include other implementation methods, which are not listed here one by one. Any implementation method that can realize the immediate execution of the execution message corresponding to the pixel copy function and the immediate execution of the screenshot function for SurfaceView is acceptable.

[0080] Step S207: Display the target frame image in the second interface of the target application.

[0081] Step S208: Obtain the screen image cache through the handle of the screen image cache.

[0082] Step S209: Draw the screen image cache in the second drawing surface to play the live video of the target live broadcast room.

[0083] For example, after obtaining the target frame image, the target frame image is displayed within the second interface. Simultaneously, a handle to the screen image cache, i.e., a surface, is obtained, and live video data is obtained through the surface. Specifically, the screen image cache handle can be called through a drawing surface access interface to obtain the screen image cache, i.e., the live video data used to implement live video playback. This process, i.e., loading the screen image cache, is described in detail in the embodiment shown in FIG. 2 and will not be further elaborated here. Subsequently, the screen image cache is drawn within the second drawing surface to achieve the purpose of playing the live video from the target live broadcast room.

[0084] For example, as shown in FIG8 , the specific implementation of step S209 includes:

[0085] Step S2091: Obtain the live video timestamp corresponding to the target frame image.

[0086] Step S2092: According to the live video timestamp, obtain the corresponding target video frame from the screen image cache.

[0087] Step S2093: Starting from the target video frame of the screen image cache, the screen image cache is drawn in the second drawing surface to play the live video of the target live broadcast room from the position of the target frame image.

[0088] Exemplarily, after obtaining the screen image cache, the video live broadcast timestamp corresponding to the target frame image is further obtained. The video live broadcast timestamp can be obtained through the reference information in the live streaming data. The specific implementation steps are described in detail. Then, according to the video live broadcast timestamp corresponding to the target frame image, a video frame whose playback timestamp is the same or similar to the video live broadcast timestamp is found from the screen image cache, that is, the target video frame. Since the target video frame and the timestamp corresponding to the target frame image are the same or similar, it can be ensured that the image content in the target video frame is the same or similar to the video content of the target frame image. Then, starting from the target video frame, the screen image cache is drawn in the second drawing surface, thereby achieving the effect of playing the live video of the target live room from the location of the target frame image. Through the above steps, when the terminal device switches from the first interface to the second interface, a seamless connection is formed between the preview video and the live video, avoiding the skipping of part of the live content due to the time-consuming switching process, and improving the viewing effect.

[0089] Referring to FIG9 , FIG9 is a flow chart of the third method for switching interfaces provided by an embodiment of the present disclosure. The method of this embodiment can be applied in a terminal device, and the method for switching interfaces includes:

[0090] Step S301: In the second interface of the target application, the live video of the target live room is played, and after receiving the exit instruction for the target live room, the live stream data of the target live room is pulled.

[0091] Step S302: Obtain the target frame image of the target live broadcast room through the live broadcast stream data of the target live broadcast room.

[0092] Step S303: Display the target frame image in the first interface until the preview video of the target live broadcast room is loaded, and then play the preview video of the target live broadcast room in the first interface.

[0093] Exemplarily, the interface switching method provided in this embodiment can be applied to the application scenario of launching a live broadcast room. Referring to the application scenario schematic diagram shown in Figure 1, the second interface is the live broadcast room interface within the target application. When the terminal device receives an exit instruction for the target live broadcast room, the terminal device pulls the live stream data of the target live broadcast room, and generates a target frame image based on the live stream data of the target live broadcast room. Then, it returns to the main page of the target application and displays the target frame image in the first interface within the main page, that is, the live broadcast room preview interface. After the preview video of the target live broadcast room is loaded, the preview video of the target live broadcast room is played in the first interface, thereby completing the process of switching from displaying the second interface to displaying the first interface, that is, the process of exiting the live broadcast room.

[0094] In one possible implementation, step S302 obtains the target frame image of the target live broadcast room through the live broadcast stream data of the target live broadcast room, including: creating a renderer object through the main thread of the target application; executing the target function through the renderer object to process the live broadcast stream data to obtain the target frame image, wherein the target function includes a pixel copy function, and the pixel copy function realizes the immediate generation of the target frame image by receiving the rewritten target method.

[0095] In a possible implementation, the target method is a message sending method at a specific moment.

[0096] In one possible implementation, the steps in step S302: executing the target function, processing the live stream data, and obtaining the target frame image, the specific implementation method includes: calling the drawing surface access interface to obtain the screen image cache based on the drawing surface view corresponding to the live stream data; taking the screen image cache and the specific time message sending method of the message processor object as input, calling the pixel copy function to generate the target frame image, wherein the specific time message sending method of the message processor object is overwritten, and the specific time message sending method is used to immediately execute the execution message corresponding to the pixel copy function.

[0097] In this embodiment, the corresponding target frame image is obtained through live streaming data, and the target frame image is displayed before the first interface has loaded the screen image cache, thereby avoiding the problem of a black screen in the first interface during the jump from the second interface to the first interface, and increasing the smoothness of the interface switching process. Among them, the process of generating the target frame image (step S302) involved in this embodiment is the same as the specific implementation method of generating the target frame image in the embodiment corresponding to Figures 2 to 8, that is, the method of generating the target frame image in the embodiment corresponding to Figures 2 to 8 can also be partially or completely applied to this embodiment. The specific implementation method can refer to the relevant introduction in the embodiment corresponding to Figures 2 to 8, and will not be repeated here.
