Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to enhance the data decoding performance of the electronic device, the embodiment of the invention provides a data decoding method, the electronic device and a machine-readable storage medium. Next, a data decoding method provided in an embodiment of the present invention will be described first. The method is applied to electronic equipment, and the electronic equipment can be display equipment with a display function, such as a television, a conference panel and the like, and can also be hardware equipment with core processing capability, such as a personal computer, a server and the like. The electronic equipment comprises a main processor and a coprocessor, wherein the main processor mainly provides core processing functions of the electronic equipment, such as target identification, data operation, control and the like, and the coprocessor mainly provides a streaming media data decoding function. The data decoding method provided by the embodiment of the invention is specifically realized by the interaction of a main processor and a coprocessor in the electronic equipment.
As shown in fig. 1, a data decoding method provided by an embodiment of the present invention may include the following steps.
S101, the main processor 10 obtains streaming media data and a stream attribute parameter of the streaming media data.
The code stream attribute parameters represent the coding and decoding characteristics of the stream media data.
S102, the main processor 10 sends the streaming media data and the stream attribute parameter to the coprocessor 20.
And S103, the coprocessor 20 configures a decoder according to the code stream attribute parameters, and decodes the streaming media data by using the decoder.
By applying the embodiment of the invention, the main processor acquires the streaming media data and the code stream attribute parameters of the streaming media data; and sending the streaming media data and the code stream attribute parameters to the coprocessor, wherein the code stream attribute parameters represent the coding and decoding characteristics of the streaming media data, so that after receiving the streaming media data and the code stream attribute parameters, the coprocessor can correspondingly configure a decoder according to the code stream attribute parameters, and the configured decoder is used for decoding the streaming media data. The coprocessor correspondingly configures the decoder according to the code stream attribute parameters after receiving the stream media data and the code stream attribute parameters of the stream media data, and the configured decoder can adaptively decode the received stream media data.
As a main processor providing a core processing function of an electronic device, when streaming media data that needs to be locally displayed by the electronic device exists, the main processor may first acquire the streaming media data, and since the streaming media data may be transmitted from another electronic device or copied from an external memory, the streaming media data may be acquired by the main processor through a transmission interface between the electronic device and another electronic device, or acquired by the processor from an external memory connected to the electronic device. When the streaming media data is acquired, the code stream attribute parameters of the streaming media data can be acquired, and the code stream attribute parameters represent the encoding and decoding characteristics of the streaming media data, that is, the code stream attribute parameters stipulate the relevant information of how to encode and decode the streaming media data. The code stream attribute parameter may be carried in the streaming media data, or may be obtained by analyzing the streaming media data after the streaming media data is obtained.
Optionally, S101 may specifically be: the main processor 10 obtains streaming media data input by an application program when calling a media playing interface and generated code stream attribute parameters, wherein the media playing interface is used for providing playing service for the streaming media data.
Generally, a user of an electronic device may check streaming media data by running a third party APP (Application, Application program) such as a cloud conference, a cloud study, and the like, and when the third party APP is run, input streaming media data to be checked, the APP may call a media playing interface (for example, a MediaPlayer interface of an Android system), and the media playing interface is a standard decoding interface of an operating system of the electronic device, and can provide a playing service for the streaming media data, and a decoding mode of the streaming media data is agreed. The media playing interface can analyze the corresponding code stream attribute parameters according to the format of the stream media data. Therefore, the main processor can intercept the streaming media data and the code stream attribute parameters from the media playing interface when the application program calls the media playing interface. The main processing may obtain, in addition to the stream attribute parameters of the streaming media data, pre-configured decoding-related parameters such as decoder initialization parameters and display parameters. The codestream attribute parameters, decoder initialization parameters, display parameters, etc. may be sent to the co-processor together.
Therefore, in the embodiment of the invention, the electronic device does not need to make special limitation on the third party APP, does not require that the third party APP can only run the streaming media data in the fixed format, and can call the standard media playing interface from the third party APP, and the adaptive decoding operation is realized by the self-defined co-processing mode of the electronic device, so that the non-inductive adaptation to the third party APP can be realized.
After acquiring the streaming media data and the code stream attribute parameters, the main processor sends the streaming media data and the code stream attribute parameters to the coprocessor and the coprocessor decodes the streaming media data and the code stream attribute parameters. After the coprocessor receives the streaming media data and the code stream attribute parameters, the code stream attribute parameters represent the coding and decoding characteristics of the streaming media data, so that a decoder can be correspondingly configured according to the code stream attribute parameters, and the configured decoder can decode the streaming media data in a targeted manner, so that the decoder is more flexible, and therefore, the electronic equipment can decode the streaming media data in different formats adaptively, and the data decoding performance of the electronic equipment is improved.
Optionally, the main processor 10 and the coprocessor 20 are connected via a network.
Correspondingly, S102 may specifically be: the main processor 10 encapsulates the streaming media data and the code stream attribute parameters to obtain an encapsulated data packet; the data packet is sent to the coprocessor 20 via the network according to a predetermined network protocol.
The coprocessor 20 decapsulates the data packet after receiving the data packet sent by the main processor 10, and thus obtains the streaming media data and the code stream attribute parameters.
In an implementation manner of the embodiment of the present invention, the main processor and the coprocessor may be connected via a network, and accordingly, the main processor needs to encapsulate the streaming media data and the attribute parameters of the code stream before sending the streaming media data and the attribute parameters of the code stream, generally, data encapsulation is performed based on a network Protocol, for example, the main processor and the coprocessor are connected via a network that satisfies Transmission Control Protocol (TCP)/Internet Protocol (IP), when performing data encapsulation, encapsulation is performed according to the TCP/IP requirement, and accordingly, when receiving a data packet sent by the main processor, the coprocessor decapsulates the data packet, so as to obtain the streaming media data and the attribute parameters of the code stream, and a specific decapsulating process is also determined according to a format requirement of a specific network Protocol, and will not be described in detail herein.
The main processor 10 and the coprocessor 20 may be connected through a USB, a serial port, or the like, in addition to the above network connection, which is not described in detail herein.
Optionally, the streaming media data is multiple paths of streaming media data.
Correspondingly, the step of decoding, by the coprocessor 20 in S103, the streaming media data by using a decoder may specifically be: the coprocessor 20 decodes each path of streaming media data by using a decoder; and splicing the decoded streaming media data according to a preset splicing mode.
The coprocessor may provide multi-channel decoding, that is, the input streaming media data may be multi-channel streaming media data, for example, in some scenarios, cameras are deployed at different positions, and each camera may acquire a video at a different position, so that the streaming media data transmitted to the electronic device may be multi-channel, the coprocessor may decode each channel of streaming media data separately using a decoder, and the decoding of each channel of streaming media data may be performed synchronously or asynchronously. In addition, one decoder may decode each path of streaming media data, or a plurality of decoders having the same structure may decode each path of streaming media data, respectively, and this is not particularly limited. Because the multiple paths of streaming media data are stored and displayed respectively, the storage and display are not convenient for a user to check, and for the convenience of the user to check, the coprocessor can splice the decoded multiple paths of streaming media data according to a preset splicing mode.
After the coprocessor obtains the decoded streaming media data, the streaming media data can be stored locally or in a storage medium of the electronic device, and the coprocessor waits for a main processor or other units to obtain the streaming media data when necessary. Of course, in an implementation manner, after obtaining the decoded streaming media data, the coprocessor may directly send the obtained streaming media data to the main processor, and the main processor performs processing such as storage and display.
Based on the embodiment shown in fig. 1, an embodiment of the present invention further provides a data decoding method, which is applied to an electronic device that includes a main processor 10, a coprocessor 20 and a display screen 30, and as shown in fig. 2, the following steps may be included.
S201, the main processor 10 obtains the streaming media data and the stream attribute parameter of the streaming media data.
The code stream attribute parameters represent the coding and decoding characteristics of the stream media data.
S202, the main processor 10 sends the streaming media data and the stream attribute parameter to the coprocessor 20.
S203, the coprocessor 20 configures a decoder according to the bit stream attribute parameter, and decodes the streaming media data by using the decoder.
S204, the coprocessor 20 sends the decoded streaming media data to the main processor 10.
S205, the main processor 10 displays the decoded streaming media data on the display screen 30.
In the embodiment of the invention, the electronic equipment processing comprises a main processor, a coprocessor and a display screen, wherein the display screen is used for displaying the streaming media data. The display function of the display screen is specifically controlled by the main processor, so that after the coprocessor obtains the decoded streaming media data, the decoded streaming media data can be sent to the main processor, the main processor controls the display screen to display the decoded streaming media data, the specific display control process can be that the decoded streaming media data is sent to the display screen in a display driving instruction mode, and the display screen displays the decoded streaming media data according to the display driving instruction.
Optionally, the main processor 10 is connected to the coprocessor 20 via a multimedia interface.
S204 may specifically be: the coprocessor 20 transmits the decoded streaming media data to the main processor 10 in the form of a multimedia signal through a multimedia interface.
S205 may specifically be: the main processor 10 displays the received multimedia signal on a display screen.
A conventional way to insert and lose streaming media data between a main processor and a coprocessor is that the coprocessor stores decoded streaming media data into a specified storage medium (e.g., a Dynamic Random Access Memory (DRAM)) of an electronic device, and the main processor reads the streaming media data from the specified storage medium. It can be seen that this way of interaction between processors is complex. In an implementation manner of the embodiment of the present invention, the main processor and the coprocessor are connected through a Multimedia Interface, for example, through an HDMI (High Definition Multimedia Interface), so that the coprocessor can directly send decoded streaming media data to the main processor through the Multimedia Interface in the form of a Multimedia signal, and the main processor can directly display the received Multimedia signal on the display screen.
As shown in fig. 3, a specific process of an electronic device implementing a data decoding method is provided, where the electronic device runs an Android system, and in a running process of a third-party APP, a MediaPlayer interface of the Android system is called, and a main processor intercepts, in the MediaPlayer interface, each code stream (including streaming media data and code stream attribute parameters) transmitted through the MediaPlayer interface, performs code stream encapsulation, and sends the encapsulated code stream to a coprocessor through a network. The coprocessor receives the code stream through the network, decapsulates the code stream to obtain multiple paths of videos, decodes each path of video according to received code stream attribute parameters to obtain multiple pictures, performs screen splitting and splicing on the multiple pictures to obtain spliced pictures, finally outputs the spliced pictures to the main processor through the HDMI, and the main processor displays the received HDMI signals on a display screen connected with the main processor.
