[0031] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0032] The shooting control method provided by the embodiment of the present disclosure is applied to the shooting control scenario of a camera device with a network connection function. When using a camera device with a network connection function, users usually need to adjust and control various parameters. These devices have a variety of adjustable parameters, such as focal length, exposure, white balance, etc. By connecting to the network and using a terminal device such as a computer, a smart phone or a tablet computer, the user can remotely control and adjust these parameters.

[0033] However, there is no mature protocol specification for the parameter control of camera devices with network connection function. Therefore, in the relevant technology, a communication protocol specifically responsible for device parameter control is usually defined. When parameter control is required, the terminal needs to select the corresponding protocol to perform parameter control according to different requirements.

[0034] In the scenario of controlling the parameters of a camera device with a network connection function, two devices are usually involved. One of them plays the role of a camera, and the other plays the role of a monitor. For the convenience of description in the following embodiments of the present disclosure, the device playing the role of a monitor is referred to as the first device, and the device playing the role of a camera is referred to as the second device.

[0035] Figure 1 FIG. 1 is a flow chart of a shooting control method according to an exemplary embodiment. Figure 1As shown, the shooting control method is used in a terminal and includes the following steps.

[0036] In step S11, when the first electronic device requests to control the second electronic device to collect media files, a control parameter is determined, where the control parameter is a parameter for controlling the second electronic device to collect media files.

[0037] In the embodiment of the present disclosure, the parameters for controlling the second electronic device to collect media files refer to controlling the parameters of the second electronic device when collecting media files by setting specific parameters. These parameters may involve multiple aspects, including but not limited to: white balance, exposure, sensitivity (ISO) and other parameters.

[0038] In step S12, the control parameters are encapsulated in a streaming media text format to obtain a control instruction in a streaming media text format.

[0039] In the disclosed embodiment, the control parameters are combined and packaged in a specific streaming media text format to form a streaming media text format containing control instructions. Such control instructions can be sent to a corresponding device or system as a command or instruction to control its behavior, set its parameters or perform specific operations.

[0040] Among them, the streaming media text format is a specific data format, which is usually used to transmit audio, video or other multimedia data during network transmission. By encoding and encapsulating the control parameters in the streaming media text format, the control instructions can have a certain structure and markup, which is convenient for parsing and processing during the transmission process. Such control instructions in the streaming media text format can be parsed and recognized by the receiver, and then the corresponding operations are performed according to the control parameters therein, such as adjusting certain parameters of the device. By using a unified streaming media text format, interoperability between devices can be achieved, and remote control and configuration can be conveniently performed.

[0041] In step S13, a control instruction in a streaming media text format is sent to the second electronic device.

[0042] In the disclosed embodiment, the control instruction in the streaming media text format includes specific parameters and commands to ensure that the second electronic device can correctly perform the required operation.

[0043] In the related art, in order to achieve control over the shooting process, the terminal needs to select the corresponding protocol to perform parameter control according to different needs. In the embodiment of the present disclosure, when the first device requests to control the second device to collect media files, the control parameters are determined and encapsulated as instructions in a streaming text format, and then sent to the second device. It is understandable that in order to transmit the content captured by a camera device with a network connection function, the camera device with a network connection function usually supports some streaming protocols, such as: Real-time Streaming Protocol (RTSP) and the like. In the embodiment of the present disclosure, by encapsulating the control parameters as instructions in a streaming text format and sending them to the second device, direct control of the shooting process is achieved without the need to select a corresponding protocol to perform parameter control according to different needs.

[0044] Figure 2 FIG. 1 is a flow chart showing a method for determining a streaming media text format control instruction according to an exemplary embodiment. Figure 2 As shown, the method for determining streaming media text format control instructions includes the following steps.

[0045] In step S21, based on the control parameter, the parameter type, parameter value, version information and identification information characterizing the control parameter are obtained.

[0046] In the disclosed embodiment, the first device obtains information such as parameter type, parameter value, version information, and identification information based on the control parameter.

[0047] Among them, the parameter type is used to indicate the type or attribute of the parameter, which provides important clues about the classification and characteristics of the parameter. The parameter value represents a specific numerical value or setting, through which the first device can understand the specific value range and current setting of the parameter. Version information may include the version number of the control parameter and related update records, which helps the first device understand the historical evolution of the parameter and possible improvement directions. The identification information is used to identify a specific control parameter so that it can be independently identified and distinguished in the system.

[0048] In step S22, the parameter type, parameter value, version information and identification information are converted into plain text and encapsulated as the content of the parameter setting method in the streaming media transmission protocol to obtain a control instruction in the streaming media text format.

[0049] In the disclosed embodiment, in order to convert the parameter type, parameter value, version information and identification information into plain text form, the object parameter format should be considered when selecting the control parameter. This is because some parameter formats are plain text formats, which are suitable for use as a format for representing control parameters. For example: object representation (JSON object) format. Some parameter formats are binary formats, which are not suitable for use as formats for identifying control parameters.

[0050] In the disclosed embodiment, based on the control parameter, the type, parameter value, version information and identification information of the control parameter are converted into a plain text format and encapsulated into a control instruction in a streaming media text format. After encapsulation, the control parameter can be directly transmitted through the streaming media transmission protocol, without the need to select the corresponding protocol to perform parameter control according to different requirements.

[0051] Figure 3 FIG. 1 is a flow chart of a shooting control method according to an exemplary embodiment. Figure 3 As shown, the shooting control method is used in a terminal and includes the following steps.

[0052] In step S31, when the first electronic device requests to control the second electronic device to collect media files, a control parameter is determined, where the control parameter is a parameter for controlling the second electronic device to collect media files.

[0053] In step S32, the control parameters are encapsulated in a streaming media text format to obtain a control instruction in a streaming media text format.

[0054] In step S33, a control instruction in a streaming media text format is sent to the second electronic device.

[0055] Regarding the above steps in this embodiment, the specific method of performing the operation in each step has been described in the relevant Figure 1 The invention has been described in detail in the embodiments of the present invention and will not be described in detail here.

[0056] In step S34, response information sent by the second electronic device is received. The response information is encapsulated in a streaming media text format and is used to represent the execution result of the second electronic device executing the control instruction.

[0057] The response information is encapsulated in a streaming media text format. In other words, the response information is transmitted from the second electronic device to the first electronic device using a streaming media protocol.

[0058] In the disclosed embodiment, the response information sent by the second electronic device is transmitted to the first electronic device via the streaming media protocol. That is, when the second electronic device transmits the response information to the first electronic device, it is not necessary to perform parameter control according to other protocols, and the transmission of the response information can be completed by directly selecting the ready-made streaming media protocol. Therefore, through the disclosed embodiment, it is possible to directly control the shooting process and receive the response information without selecting the corresponding protocol to perform parameter control according to different needs.

[0059] It can be understood that, in order to indicate whether the control instruction is executed successfully, the response information sent by the second electronic device should include a field that can reflect whether the control instruction is executed successfully.

[0060] In one embodiment provided by the present disclosure, the response information encapsulated in the streaming media text format includes a first field, the first field includes a first array representing the successful execution of the control instruction, or includes a second array for representing parameter information corresponding to the execution of the control instruction.

[0061] The first field may include both a first array representing the successful execution of the control instruction and a second array representing parameter information corresponding to the execution of the control instruction. However, the first field may not include both the first array and the second array at the same time, because that would result in the field being unable to accurately represent the execution result of the control instruction.

[0062] In the disclosed embodiment, the instruction execution result feedback specification is as follows: if the control instruction is successfully executed, the instruction feedback will not include the "error" field, but must include the "result" or "results" field.

[0063] In another embodiment provided by the present disclosure, the response information encapsulated in the streaming media text format includes a second field, and the second field includes a third array representing a control instruction execution failure flag and execution failure content.

[0064] The second field needs to include both the control instruction execution failure flag and the execution failure content. If the third array in the second field does not include both the control instruction execution failure flag and the execution failure content, the field cannot accurately represent the execution result of the control instruction.

[0065] In the disclosed embodiment, the instruction execution result feedback specification is as follows: if the control instruction execution fails, the instruction feedback will not include the "result" field or the "results" field, but must include the "error" field.

[0066] Here, it is necessary to explain the meaning of the items that may appear in the instruction execution result feedback: "error" means: error, "result" / "results" means: result / results. In the instruction feedback, the "result" field contains one element, which is an array of fixed length. The "results" field contains multiple elements, each element is also an array of fixed length, and the array length and data type of these elements are determined by the second electronic device. The "error" field contains two elements, namely, error_code of integer type and error_message of string type, and its format is [error_code, error_message].

[0067] In the above embodiments, the format of the control parameters involved may be a JSON object format, and the format of the streaming media text involved may be a format corresponding to the RTSP protocol.

[0068] Figure 4 FIG. 1 is a flow chart of a shooting control method according to an exemplary embodiment. Figure 4 As shown, the shooting control method is used in a terminal and includes the following steps.

[0069] In step S41, when the first electronic device requests to control the second electronic device to collect media files, a control parameter is determined, where the control parameter is a parameter for controlling the second electronic device to collect media files, and the format of the control parameter is a JSON object.

[0070] For the convenience of description, the JSON object format is selected as the format of the control parameters in the embodiment of the present disclosure, and the streaming media text format is set to the format corresponding to the RTSP protocol. It should be clear that the selection in the embodiment of the present disclosure is only for the convenience of description, and does not limit the format of the control parameters to the JSON object format, or the streaming media text format to the format corresponding to the RTSP protocol.

[0071] In the embodiment of the present disclosure, the camera parameters are encapsulated by the following method: querying all parameters supported by the remote device in the format of JSON object, modifying one or more parameters in these JSON objects, converting the modified JSON object into text as the content of setting parameters (SET_PARAMETER) in the RTSP protocol and sending it to the second electronic device, the second electronic device parses the SET_PARAMETER request in the RTSP message and executes the corresponding application programming interface (API), and the second electronic device encapsulates the execution result of the API into JSON-RPC format text.

[0072] In step S42, the control parameters in the JSON object format are encapsulated in the RTSP text format to obtain a control instruction in the RTSP text format.

[0073] In the disclosed embodiment, since the RTSP protocol is a plain text protocol, the control instruction carrier is in plain text format. The control instruction is encapsulated in JSON object format. For each parameter, the control instruction contains the following information of the parameter: parameter type, parameter value, version information and identification information.

[0074] Specifically, in the control instruction, the "method" field corresponds to the parameter type of the parameter, the "params" field corresponds to the parameter value of the parameter, the "version" field corresponds to the version information of the parameter, and the "id" field corresponds to the identification information of the parameter.

[0075] The specifications of each field are as follows: the "method" field in the control instruction is determined by the implementation of the second electronic device, the length of the "params" field in the control instruction and the type of each element are determined by the second electronic device, and the control instruction must contain a "version" field. "version" is of string type (eg "1.0"), and the "id" field in the control instruction is of integer type ("0" is a reserved field and cannot be used). Its value range is 1-2147483647, that is, 0x00000001–0x7FFFFFFF.

[0076] In step S43, a control instruction in RTSP text format is sent to the second electronic device.

[0077] In the embodiment of the present disclosure, the first electronic device uses the SET_PARAMTER method in its standard protocol to send the control instruction.

[0078] Here, it is necessary to explain the process of the first electronic device sending the control instruction using the SET_PARAMETER method based on the RTSP protocol. The specific process is as follows:

[0079] The first electronic device establishes an RTSP session connection with the second electronic device. The first electronic device sends an option request (OPTIONS) to obtain a method list and protocol version information supported by the second electronic device.

[0080] The first electronic device sends a description request (DESCRIBE) to obtain information about a specific resource (eg, a video stream) on the second electronic device.

[0081] The first electronic device sends a setup request (SETUP) to establish a transmission channel. In the SETUP request, the first electronic device specifies the transmission protocol to be used (such as RTP / UDP, RTP / TCP, etc.) and allocates the corresponding port number. Once the setup is completed, the first electronic device can send a play request (PLAY) to start playing the media stream.

[0082] It is understandable that the RTSP protocol only transmits control instructions, not RTSP data. Therefore, in addition to specifying the communication protocol used to transmit control instructions as RTSP, the first electronic device must also specify the communication protocol used for RTSP data transmission. The transmission protocol for RTSP data transmission that is usually used in conjunction with the RTSP protocol is RTP / UDP or RTP / TCP.

[0083] The first electronic device sends a request to the second electronic device using the SET_PARAMETER method, specifies the parameter to be controlled and the corresponding parameter value, and waits for a response from the second electronic device.

[0084] In step S44, it is determined whether the control instruction is executed successfully.

[0085] If the control instruction is executed successfully, execute step S45.

[0086] In step S45, the response information encapsulated in the RTSP text format includes a first field, and the first field includes a first array representing that the control instruction is successfully executed, or includes a second array for representing parameter information corresponding to the execution of the control instruction.

[0087] If the control instruction is not executed successfully, step S46 is executed. In step S46, the response information encapsulated in the RTSP text format includes a second field, and the second field includes a third array representing the control instruction execution failure mark and the execution failure content. Among them, the second field needs to include the control instruction execution failure mark and the execution failure content. If the third array in the second field does not include the control instruction execution failure mark and the execution failure content at the same time, it will cause the field to be unable to accurately represent the execution result of the control instruction.

[0088] Regarding the above steps in this embodiment, the specific manner of performing the operation in each step has been described in detail in the above embodiments and will not be elaborated here.

[0089] Here, it is necessary to explain the meaning of the items that may appear in the instruction execution result feedback: "error" means: error, "result" / "results" means: result / results.

[0090] In the disclosed embodiment, the instruction execution result feedback specification is as follows: If the control instruction is successfully executed, the instruction feedback will not contain the "error" field, but must contain the "result" or "results" field. If the control instruction fails to execute, the instruction feedback will not contain the "result" field or the "results" field, but must contain the "error" field. In the instruction feedback, the "result" field contains one element, which is an array of a fixed length. The "results" field contains multiple elements, each element is also an array of a fixed length, and the array length and data type of these elements are determined by the second electronic device. The "error" field contains two elements, namely, an error_code of integer type and an error_message of string type, and its format is [error_code, error_message].

[0091] For ease of understanding, the present disclosure will now describe the above-mentioned shooting control method with examples.

[0092] Example: Implementation of remote control of white balance WB parameters in camera mode:

[0093]

[0094]

[0095] After executing step S45 or step S46, execute step S47. In step S47, receive the response information sent by the second electronic device, the response information is encapsulated in RTSP text format and used to represent the execution result of the second electronic device executing the control instruction.

[0096] In the embodiment of the present disclosure, the second device needs to determine whether the control instruction is executed successfully. On the one hand, if the control instruction is executed successfully, the second device includes a first field in the response information encapsulated in the RTSP text format. The field may include a first array for characterizing the successful execution of the control instruction, or a second array for representing the parameter information corresponding to the execution of the control instruction. On the other hand, if the control instruction is not successfully executed, the second device includes a second field in the response information encapsulated in the RTSP text format. The field includes a third array for characterizing the failure of the control instruction and the execution failure content. Regardless of whether the control instruction is executed successfully, the first device will receive the response information sent by the second electronic device, which is also encapsulated in the RTSP text format and used to characterize the execution result of the second electronic device executing the control instruction. In the embodiment of the present disclosure, when the first electronic device requests to control the second electronic device to collect media files, the second electronic device uses the camera parameter acquisition method (Camera.getParameters) to collect control parameters, and then encapsulates the control parameters into JSON object format, and waits for the first electronic device to request streaming playback through the RTSP protocol. The first electronic device requests streaming playback, and at the same time, the first electronic device sends a control instruction to the second electronic device to remotely control the second electronic device, such as adjusting parameters such as white balance, exposure, and ISO. After the second electronic device receives the control instruction, it performs the corresponding operation and feeds back the response information to the first electronic device. The response information is also encapsulated in the JSON object format and fed back to the first electronic device via the RTSP protocol. The response information is divided into two situations, one is the successful execution of the control instruction, and the other is the failure of the control instruction. But in either case, the response information is encapsulated in the JSON object format and sent via the RTSP protocol. At the same time, the control instruction is also encapsulated in the JSON object format and sent via the RTSP protocol. Therefore, during the entire shooting control process, the first electronic device can directly control the shooting process without having to select the corresponding protocol to perform parameter control according to different needs.

[0097] Based on the same concept, the embodiment of the present disclosure also provides a shooting control device.

[0098] It is understandable that in order to realize the above functions, the shooting control device provided by the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art may use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.
