It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0033] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0034] The display device provided by the embodiments of the present application may have various implementation forms. For example, it may be a television, a smart TV, a laser projection device, a monitor, an electronic bulletin board, an electronic table, etc. Figure 1 and Figure 2 This is a specific implementation manner of the display device of the present application.

[0035] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0036] Figure 1 Schematic diagram of the operation scenario between a household device and a control device according to one or more embodiments of the present application, as Figure 1 shown, the user can operate the display device 200 through the terminal device 300 and / or the control device 100. The control device 100 can be a remote control. The communication between the remote control and the display device includes infrared protocol communication, Bluetooth protocol communication, wireless or other wired methods to control the display device 200. The user can input user instructions through the buttons on the remote control, voice input, control panel input, etc. to control the display device 200. In some embodiments, a mobile terminal, a tablet computer, a computer, a laptop computer, and other intelligent devices can also be used to control the display device 200.

[0037] In some embodiments, the display device provided by the embodiments of the present disclosure can be the above-mentioned display device 200. Among them, a target application is installed in the display device 200. When the user needs to play a multimedia file, the multimedia file can be played through the target application. At this time, the target application responds to the play operation of playing the multimedia file, obtains the multimedia data of the multimedia file, and displays a prompt message for indicating the buffered multimedia data of the multimedia file; the target application parses the multimedia data to obtain the video data of the first frame of the multimedia file; when the target application completes the pre-operation on the video data of the first frame, it indicates that the first frame of the video data needs to be displayed at the next moment. Therefore, at the next moment, while stopping displaying the prompt message, the first frame of the video data is displayed, which ensures the moment when the target application closes the displayed prompt message and solves the problem of how to ensure that the video application closes the prompt message.

[0038] Figure 2 Shows the hardware configuration block diagram of the display device 200 according to an exemplary embodiment. As Figure 2 shown, the display device 200 includes at least one of a tuner demodulator 210, a communicator 220, a detector 230, an external device interface 240, a controller 250, a display 260, an audio output interface 270, a memory, a power supply, and a user interface 280. The controller includes a central processing unit, a video processor, an audio processor, a graphics processor, RAM, ROM, and a first interface to an nth interface for input / output. The display 260 can be a display with touch function, such as a touch display. The detector 230 is used to collect signals from the external environment or interact with the outside.

[0039] In some examples, the external device interface 240 may include, but is not limited to, the following: a high-definition multimedia interface (HDMI), an analog or data high-definition component input interface (component), a composite video input interface (CVBS), a USB input interface (USB), an RGB port, etc., any one or more interfaces. It can also be a composite input / output interface formed by the above multiple interfaces.

[0040] In some embodiments, the controller 250 controls the operation of the display device and responds to user operations by means of various software control programs stored in the memory. The controller 250 controls the overall operation of the display device 200.

[0041] In some examples, taking the display device 200 applying one or more embodiments as the television 1 and the operating system of the television 1 being the Android system as an example, as Figure 3 shown, the television 1 can be logically divided into an applications layer (abbreviated as the "application layer") 21, an application framework layer (abbreviated as the "framework layer") 22, an Android runtime and system library layer (abbreviated as the "system runtime library layer") 23, and a kernel layer 29.

[0042] Among them, the application layer 21 includes one or more applications. The applications can be system applications or third-party applications. For example: the application layer 21 includes a target application, and the target application is used to play multimedia files.

[0043] The framework layer 22 provides application programming interfaces (APIs) and programming frameworks for the applications in the application layer 21. The system runtime library layer 23 provides support for the upper layer, i.e., the framework layer 22. When the framework layer 22 is used, the Android operating system will run the C / C++ libraries included in the system runtime library layer 23 to implement the functions to be achieved by the framework layer 22. The kernel layer 29 serves as software middleware between the hardware layer and the application layer 21 and is used to manage and control hardware and software resources.

[0044] In some examples, the display device provided by the embodiments of the present application may be the above-mentioned television 1. Among them, a target application is installed in the television 1. When playing a multimedia file, the target application calls the media player middleware of the framework layer 22 of the Android system, and listens to the first prompt message (kWhatOutputFramesRendered) of the video demultiplexing and parsing plug-in (MediaCodec) through the media player middleware, and further detects the value of the target identifier (sys.media.video.render), so as to determine the accurate time when the video data of the first frame is displayed. For example, when the user needs to play a multimedia file, the target application can play the multimedia file through the target application. At this time, the processing unit 101 of the target application responds to the play operation of playing the multimedia file, controls the acquisition unit 102 to acquire the multimedia data of the multimedia file, and controls the display unit 103 to display a prompt message for indicating the buffered multimedia data of the multimedia file; the processing unit 101 of the target application parses the multimedia data acquired by the acquisition unit 102 through the video decoding module 202 to obtain the video data of the first frame of the multimedia file; when the processing unit 101 of the target application completes the pre-operation on the video data of the first frame through the decoding display control module 201, the display control module 203 controls the display unit 103 to exit the display of the prompt message. In this way, the target application can determine whether to exit the display of the prompt message based on the first indication information. Since the first prompt message is generated based on whether the pre-operation on the video data of the first frame is completed, when the pre-operation on the video data of the first frame is completed, the display of the prompt message is exited, ensuring the moment when the target application closes the displayed prompt message.

[0045] In some examples, the decoding display control module 201 is a module of the media player middleware, and sends the first indication information to the processing unit 101 of the target application after listening to the information that the pre-operation of the video data of the first frame is executed sent by the display control module 203.

[0046] In some examples, the video decoding module 202 is a module of the media player middleware. The video decoding module 202 sends the parsed video elementary stream (ES) data into the video demultiplexing and parsing plug-in (MediaCodec) of the Android system, and obtains the decoded video data (usually YUV data) from MediaCode, and calls the interface of MediaCode through the decoding display control module 201 to display the decoded video data.

[0047] In some examples, the display control module 203 is a module of the media player middleware. The display control module 203 registers a callback function (CallBack) with MediaCodec to listen for the message kWhatOutputFramesRendered of MediaCodec. kWhatOutputFramesRendered indicates that MediaCodec sends the video data to be displayed to the display plugin. Among them, for the video data of the first decoded frame, it usually needs to wait for operations such as the initialization of the display plugin and the setting of image-related parameters in the display plugin. There is a time difference between the first kWhatOutputFramesRendered and the actual display of the video data of the first frame. Therefore, after the display control module 203 listens for the first kWhatOutputFramesRendered message, it starts a detection process for the specific flag sys.media.video.render, and detects the value of this attribute every 10 ms. When the display plugin is initialized, the initial value of sys.media.video.render is set to 0, and when the first frame of video data is displayed after the display plugin initialization is completed, the target value of sys.media.video.render is set to 1. When the display control module 203 detects that the value of sys.media.video.render is 1, it sends a first indication message indicating that the pre-operations of the video data of the first frame have been completed to the decoding and display control module 201. After that, when the processing unit of the target application determines that the first indication message has been received in the decoding and display control module 201, it exits the display prompt message.

[0048] In some examples, MediaCodec is a decoding module of the Android system. Among them, when the decoding and display control module 201 calls the interface of MediaCode to display the decoded video data, it means that the media player middleware calls the interface of MediaCodec to send the parsed video ES data to the video decoder, and realizes the decoding and display control of the video data through the interface of MediaCodec.

[0049] In some examples, the display plugin HardwareComposer is a display module of the Android system, which is used to render and display the video data decoded by the video decoding module; among them, the display plugin and MediaCodec of the Android system belong to different processes, and the interface call is an asynchronous operation.

[0050] In some examples, the decoding and display control module 201, the video decoding module 202, and the display control module 203 all belong to the media player middleware layer.

[0051] Specifically, when the execution subject of the multimedia file playing method provided in the embodiments of the present disclosure is the television 1, program codes and other data for storing the multimedia file playing method provided in the embodiments of the present disclosure are stored in the storage unit 104 of the television 1.

[0052] In the following embodiments, taking the execution subject of the multimedia file playing method provided in the embodiments of the present disclosure as the above-mentioned television 1 as an example, the method of the embodiments of the present application will be described.

[0053] The embodiments of the present application provide a multimedia file playing method, which is applied to the television 1, as Figure 4 shown. The multimedia file playing method may include S11-S13.

[0054] S11. In response to a playing operation for playing a multimedia file, obtain multimedia data of the multimedia file, and display a prompt message for indicating buffering of the multimedia data of the multimedia file.

[0055] S12. Parse the multimedia data to obtain video data of the first frame of the multimedia file.

[0056] S13. When a pre-operation on the video data of the first frame is completed, exit the display of the prompt message; wherein, the pre-operation includes one or more of image initialization and image parameter setting.

[0057] In some examples, the pre-operation further includes display time prediction; when the pre-operation on the video data of the first frame is completed, exiting the display of the prompt message includes:

[0058] When one or more of image initialization and image parameter setting on the video data of the first frame are completed, start a timer, and obtain the configuration information and operation information of the television 1.

[0059] Based on the size of the data volume of the frame data of the first frame, the configuration information, and the operation information, determine the first running duration, thus completing the operation of display time prediction.

[0060] In some examples, the configuration information includes one or more of the product model and the model of the processor.

[0061] In some examples, the operation information includes one or more of the network upload rate, the network download rate, the memory occupancy rate, and the processor occupancy rate.

[0062] Exemplarily, a first relation table pre-stored in the memory of the television 1 may be queried based on the configuration information to determine a target relation table; wherein, the target relation table includes theoretical durations corresponding to different data volumes and different operation information.

[0063] Query the target relational table based on the size of the data volume and the running information, determine the theoretical duration corresponding to the size of the data volume and the running information, and use this theoretical duration as the first running duration.

[0064] Based on the preset duration and the first running duration, determine the target duration; where the preset duration is equal to the duration required for the TV 1 to perform image initialization and / or image parameter setting on the video data of the first frame.

[0065] When the cumulative duration of the timer is equal to the target duration, exit the display of the prompt message.

[0066] Exemplarily, the first relational table is shown in Table 1.

[0067] Table 1

[0068] Configuration information Theoretical relationship table Configuration information 1 Theoretical relationship table 1 Configuration information 2 Theoretical relationship table 2

[0069] Table 2

[0070]

[0071] At this time, when the TV 1 obtains the video data of the first frame of the multimedia file, it starts the timer and obtains the configuration information and running information of the TV 1. Then, the TV 1 queries Table 1 based on the configuration information, and can determine the theoretical relational table corresponding to the configuration information, and use the theoretical relational table corresponding to the configuration information as the target relational table. Then, the TV 1 queries in the target relational table in Table 2 through the running information and the size of the data volume of the first frame of data, so as to obtain the theoretical duration corresponding to the size of the data volume and the running information, and use this theoretical duration as the first running duration.

[0072] In some examples, the pre-operation further includes timing comparison; when the pre-operation on the video data of the first frame is completed, exiting the display of the prompt message includes:

[0073] When one or more of image initialization and image parameter setting are completed for the video data of the first frame, obtain the actual liquid crystal driving signal of the video data of the first frame for which one or more of image initialization and image parameter setting are completed;

[0074] Perform timing comparison between the current liquid crystal driving signal of the TV 1 and the actual liquid crystal driving signal, and when it is determined that the current liquid crystal driving signal is the same as the actual liquid crystal driving signal, exit the display of the prompt message.

[0075] In some examples, the pre-operation includes display time prediction and timing comparison; when the pre-operation on the video data of the first frame is completed, exiting the display of the prompt message includes:

[0076] When obtaining the video data of the first frame of the multimedia file, start the timer, and obtain the actual liquid crystal driving signal of the video data of the first frame that has completed one or more of image initialization and image parameter settings, as well as the configuration information and operation information of the television 1.

[0077] Based on the size of the data volume of the frame data of the first frame, the configuration information, and the operation information, determine the first running duration;

[0078] When the cumulative duration of the timer is equal to the target duration and the current liquid crystal driving signal is the same as the actual liquid crystal driving signal, exit the display of the prompt message.

[0079] In some examples, when the pre - operation on the video data of the first frame is completed and the display prompt message is exited, the target display information can be created during the pre - operation on the video data of the first frame; wherein, the target display information is used to indicate the pre - operation on the video data. After determining to create the target display information, the target identifier is started. When the value of the target identifier is the target value, the first indication information for displaying the video data of the first frame is generated. Based on the first indication information, the display is controlled to exit the display of the prompt message. For example, when initializing MediaCodec, the initial value of the target identifier sys.media.video.render needs to be assigned 0. The display control module 203 of the media player middleware registers a callback function with MediaCodec. This callback function is used to monitor the first indication information kWhatOutputFramesRendered received by MediaCodec. This message will be received once for each rendered video frame. When the kWhatOutputFramesRendered is received for the first time, the display control module 203 creates a detection thread. This detection thread is used to loop - detect the value of sys.media.video.render. The loop - detection time can be set to detect once every 10 ms. In the Android system's display plugin HardwareComposer, customized modification is required. When the video data of the first frame is actually displayed, the value of sys.media.video.render needs to be set to 1. When the display control module 203 detects that the value of sys.media.video.render is 1, it sends a first indication message indicating that the pre - operation on the video data of the first frame has been completed to the decoding display control module 203 through the video decoding module 202. At the same time, the display control module 203 ends the thread operation. The decoding display control module 202 sends a first indication message indicating that the pre - operation on the video data of the first frame has been completed to the target application, and the entire detection process ends. The detection of sys.media.video.render is carried out in a newly created thread. This design can avoid blocking. At the same time, this thread needs to determine whether the video playback has ended each time it performs detection. If the video has ended playback, no detection is performed and the thread ends.

[0080] As can be seen from the above, for the multimedia file playing method provided by the embodiments of the present disclosure, the target application responds to the playing operation of playing the multimedia file, obtains the multimedia data of the multimedia file, and displays a prompt message for indicating buffering the multimedia data of the multimedia file; the target application parses the multimedia data to obtain the video data of the first frame of the multimedia file; when the target application completes the pre - operation on the video data of the first frame, it exits the display of the prompt message, ensuring the moment when the target application closes the displayed prompt message.

[0085] S132. When the value of the target identifier is the target value, generate the first indication information for the display of the video data of the first frame.

[0086] In some examples, the target value can be 1.

[0087] In some examples, when the value of the target identifier is the target value, it indicates that the player of the TV 1 needs to display the rendered video data of the first frame at the next moment. Therefore, the player needs to generate the first indication information for the display of the video data of the first frame. Further, the player can notify the target application that it needs to display the rendered video data of the first frame at the next moment. At this time, after receiving the first indication information sent by the player, the target application can control the display to exit the display of the prompt information, so as to more accurately determine the moment to close the display of the prompt information and ensure the user experience.

[0088] S133. Based on the first indication information, control the display to exit the display of the prompt information.
