[0035] In this way, when the display device 200 plays the locally encrypted multimedia file selected by the user, it reads the encapsulation information of the target multimedia file and the encrypted file in the same folder as the target multimedia file; the first application determines the encoding method of the target multimedia file based on the target data; in this way, the display device 200 can parse the target multimedia file according to the encoding method and play the parsed target multimedia file, so that the display device 200 can play the locally encrypted multimedia file.
[0036] Figure 2 FIG. 2 shows a hardware configuration block diagram of a display device 200 according to an exemplary embodiment. Figure 2 The display device 200 shown includes at least one of a tuner 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, a RAM, a ROM, and a first interface to an nth interface for input / output. The display 260 can be a display with a touch function, such as a touch display. The detector 230 is used to collect signals of the external environment or interaction with the outside.

[0038] In some embodiments, the controller 250 controls the operation of the display device and responds to user operations through various software control programs stored in the memory. The controller 250 controls the overall operation of the display device 200.
[0039] In some examples, the display device 200 of one or more embodiments is a TV set 1, and the operating system of the TV set 1 is an Android system. Figure 3 As shown, the television 1 can be logically divided into an application layer (Applications) (referred to as "application layer") 21, an application framework layer (Application Framework) (referred to as "framework layer") 22, an Android runtime (Android runtime) and system library layer (referred to as "system runtime library layer") 23, and a kernel layer 29.
[0040] The application layer 21 includes one or more applications. The application may be a system application or a third-party application. For example, the application layer 21 includes a first application, which is used to play non-Blu-ray multimedia files and Blu-ray multimedia files, wherein the first application creates a Blu-ray download plug-in when playing Blu-ray multimedia files.
[0041] The framework layer 22 provides an application programming interface (API) and a programming framework for the applications of the application layer 21. The system runtime layer 23 provides support for the upper layer, namely the framework layer 22. When the framework layer 22 is used, the Android operating system will run the C / C++ library contained in the system runtime layer 23 to implement the functions to be implemented by the framework layer 22. The kernel layer 29 is used as a software middleware between the hardware layer and the application layer 21 to manage and control hardware and software resources.
[0042] In some examples, the display device provided by the embodiments of the present disclosure may be the above-mentioned TV 1. A first application is installed in the TV 1, and the first application can play multimedia files. A first application is installed in the TV 1, and the first application can play multimedia files. When a user needs to play a multimedia file, the user can select the target multimedia file to be played in the application interface of the first application displayed on the TV 1. The target multimedia file is a locally encrypted multimedia file. At this time, the processing unit 201 of the first application responds to the playback operation of the target multimedia file, reads the encapsulation information of the target multimedia file, and the encrypted file in the same folder as the target multimedia file; the processing unit 201 determines the encoding method of the target multimedia file based on the target data; wherein the target data includes one or more items of the encapsulation information and the encrypted file; the processing unit 201 parses the target multimedia file according to the encoding method, and controls the display unit 202 to play the parsed target multimedia file.
[0043] Specifically, when the executing subject of the multimedia file playback method provided by the embodiment of the present disclosure is the television 1, the storage unit 203 of the television 1 is used to store data such as program codes of the multimedia file playback method provided by the embodiment of the present disclosure.
[0044] In the following embodiments, the method of the embodiment of the present disclosure is described by taking the television 1 as an example of an execution subject of the multimedia file playback method provided by the embodiment of the present disclosure.
[0045] The present disclosure provides a method for playing multimedia files, which is applied to a television set 1. Figure 4 As shown, the multimedia file playing method may include S11-S13.
[0046] S11. In response to a play operation on a target multimedia file, read encapsulation information of the target multimedia file and an encrypted file in the same folder as the target multimedia file; wherein the target multimedia file is a locally encrypted multimedia file.
[0047] In some examples, the encryption method of the locally encrypted multimedia file includes any one of China Digital Rights Management (ChinaDRM) and DRM digital rights management function Widevine.
[0048] S12: Determine the encoding method of the target multimedia file based on the target data, wherein the target data includes one or more items of the encapsulation information and the encrypted file.
[0049] In some examples, when determining the encoding method of the target multimedia file based on the target data, if the target data includes encapsulation information, and the encapsulation information includes encoding information, the encoding method of the target multimedia file is determined to be the encoding method corresponding to the encoding information. Alternatively, if the target data includes an encrypted file, the encapsulation information does not include encoding information, and the encrypted file contains encoding information, the encoding method of the target multimedia file is determined to be the encoding method corresponding to the encoding information.
[0050] In some examples, when determining the encoding method of the target multimedia file based on the target data, the target multimedia file can be input into the analysis model for data analysis to determine the encoding method of the target multimedia file. The training process of the analysis model includes:
[0051] The training sample data and the marking result of the training sample data are obtained, wherein the training sample data includes historical locally encrypted multimedia files, and the marking result includes the encoding method corresponding to the historical locally encrypted multimedia files.
[0052] The training sample data is input into the neural network model for learning, and the prediction results of the neural network model for the training sample data are obtained.
[0053] Based on the prediction results and labeling results, the network parameters of the neural network model are adjusted until the neural network model converges to obtain the analysis model.
[0054] S13, parsing the target multimedia file according to the encoding method, and playing the parsed target multimedia file.
[0055] From the above, it can be seen that in the multimedia file playback method provided by the embodiment of the present disclosure, when the TV 1 plays the locally encrypted multimedia file selected by the user, it reads the encapsulation information of the target multimedia file and the encrypted file in the same folder as the target multimedia file; the first application determines the encoding method of the target multimedia file based on the target data; in this way, the TV 1 can parse the target multimedia file according to the encoding method, and play the parsed target multimedia file, so that the TV 1 can play the locally encrypted multimedia file.
[0056] In some examples, the target data includes packaging information; Figure 4 ,like Figure 5 As shown, the above S12 can be specifically implemented through the following S120.
[0057] S120: When the encapsulation information includes coding information, determine that the coding method of the target multimedia file is the coding method corresponding to the coding information.
[0058] For example, Figure 6As shown, when the player corresponding to the first application is hsplayer pipeline, after Avdemux (mp4) parses the encapsulation information, if there is encoding information (pssh information) in the encapsulation information, the pssh information is notified to the decoder plug-in through the message mechanism of the plug-in framework. If there is no pssh information in the Avdemux encapsulation information, the result and the source path are notified to the decoder plug-in through the message mechanism of the plug-in framework.
[0059] From the above, it can be seen that in the multimedia file playback method provided by the embodiment of the present disclosure, when the TV 1 plays the locally encrypted multimedia file selected by the user, it reads the encapsulation information of the target multimedia file and the encrypted file in the same folder as the target multimedia file; when the first application includes encoding information in the encapsulation information, it determines that the encoding method of the target multimedia file is the encoding method corresponding to the encoding information; in this way, the TV 1 can parse the target multimedia file according to the encoding method, and play the parsed target multimedia file, so that the TV 1 can play the locally encrypted multimedia file.
[0060] In some possible implementation examples, the target data includes an encrypted file; Figure 5 ,like Figure 7 As shown, the multimedia file playing method provided by the embodiment of the present disclosure further includes S14.
[0061] S14: When the encapsulation information does not include the encoding information and the encrypted file contains the encoding information, determine that the encoding method of the target multimedia file is the encoding method corresponding to the encoding information.
[0062] In some examples, if pssh information does not exist in the encapsulation information after Avdemux (mp4) parses the encapsulation information, the decoder plug-in is notified through the message mechanism of the plug-in framework. The decoder plug-in reads the encryption information file (i.e., the encrypted file in the same folder as the target multimedia file) according to the source path. After that, the decoder plug-in parses the encrypted file, and if pssh information is obtained, the encoding method corresponding to the pssh information is used as the encoding method of the target multimedia file. If pssh information is not obtained, an indication information is generated to indicate that the target multimedia file cannot be played.
[0063] In some examples, if the decoder plug-in does not obtain the pssh information in the encrypted file, the decoder plug-in can obtain the historical playback information of the current user account.
[0064] The decoder plug-in determines the historical encoding method based on the historical playback information.
[0065] The decoder plug-in decodes the target multimedia file using each encoding method in the history, and uses the encoding method of the decodable target multimedia file as the encoding method of the target multimedia file.
[0066] From the above, it can be seen that in the multimedia file playback method provided by the embodiment of the present disclosure, when the TV 1 plays the locally encrypted multimedia file selected by the user, it reads the encapsulation information of the target multimedia file and the encrypted file in the same folder as the target multimedia file; when the first application does not include encoding information in the encapsulation information and there is encoding information in the encrypted file, it determines that the encoding method of the target multimedia file is the encoding method corresponding to the encoding information; in this way, the TV 1 can parse the target multimedia file according to the encoding method, and play the parsed target multimedia file, so that the TV 1 can play the locally encrypted multimedia file.
[0067] In some examples, the target data includes packaging information; Figure 4 ,like Figure 8 As shown, the above S13 can be specifically implemented through the following S130-S133.
[0068] S130, before creating a decoder, obtaining a license interaction request;
[0069] S131, sending a license interaction request via a target network protocol;
[0070] S132: After receiving the response information in response to the license interaction request, create a decoder and set the decoder in the audio and video codec framework.
[0071] In some examples, the decoder can be MediaCrypto.
[0072] In some examples, the audio and video codec framework can be Mediacodec.
[0073] S133: Parse the target multimedia file through the audio and video codec framework, and play the parsed target multimedia file.
[0074] In some examples, the interaction flow of a license interaction request includes:
[0075] 1. The first application sends program information in response to the user's selection operation, including DRM information (ContentID, encryption mode, authorization uniform resource locator (URL)) and playback URL.
[0076] 2. The first application starts playback and passes in the DRM information and URL.
[0077] 3. The player control (calling Android DRM) sends New MediaDRM, MediaDRM.opensession, New MediaCrypto to Android DRM (MediaDRM, MediaCrypto).
[0078] 4. The player control creates a player based on the URL, passes MediaCrypto, starts playback, and notifies the player kernel (obtains video data, decapsulates, decrypts DRM, decodes, and renders).
[0079] 5. The player kernel sends a request for video data to CDN (media delivery service).
[0080] 6. CDN sends the video index file and video data (optionally carrying DRM information) to the player kernel.
[0081] 7. The player core decapsulates the video data. Optionally, the player core pushes the DRM information obtained from the video index file or the video data.
[0082] 8. The player controls the on-demand content to be encrypted, and obtains a license interaction request (MediaDRM.GetKeyRequest) from Android DRM based on the DRM information.
[0083] 9. Android DRM sends a license interaction request to the player control.
[0084] 10. After receiving the license interaction request sent by the player control, the player control sends a license interaction request to the DRM content authorization service.
[0085] 11. When the DRM content authorization service receives the license interaction request sent by the player control, it sends a license interaction response (MediaDRM.provideKeyResponse) to the player control.
[0086] 12. When the player control receives the license interaction response sent by the DRM content authorization service, it sends the license interaction response to Android DRM.
[0087] 13. The player kernel sends Config Secure Code (MediaCrypto) to Android DRM.
[0088] 14. The Secure Codec of the player kernel calls Android DRM's MediaCrypto.decrypt(ES) to decrypt the content.
[0089] 15. The player core decodes and renders the video data, and controls the player core to display the rendered video data.
[0090] 16. The player controls sending MediaDRM.closeSession to Android DRM.
[0091] 17. The player controls the first application to end playing the video data.
[0092] As can be seen from the above, the multimedia file playback method provided by the embodiment of the present disclosure is that when the TV 1 plays the locally encrypted multimedia file selected by the user, it reads the encapsulation information of the target multimedia file and the encrypted file in the same folder as the target multimedia file; the first application determines the encoding method of the target multimedia file based on the target data; in this way, the TV 1 can obtain a license interaction request before creating a decoder; send the license interaction request through the target network protocol; after receiving the response information in response to the license interaction request, create a decoder and set the decoder in the audio and video codec framework; parse the target multimedia file through the audio and video codec framework, and play the parsed target multimedia file, so that the TV 1 can play the locally encrypted multimedia file.
