In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. 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.
Referring to fig. 1, a schematic structural diagram of a screen projection system provided by an embodiment of the present invention is shown, where the system includes a screen projection end device 1 and a screen-projected end device 2.
For example, the screen projection terminal device 1 is generally a user terminal device with a smaller display screen size, such as a smart phone and a tablet computer; the device 2 to be projected is usually a smart tv, a personal computer, or a smart box, which can display the display content on the device at the projection end with a larger display screen.
The screen projection protocol used by the screen projection end equipment 1 and the screen projection end equipment 2 is compatible with each other, and the screen projection can be successful; the screen projection protocol is compatible with each other, namely the screen projection end equipment 2 can successfully analyze the message sent by the screen projection end equipment 1; and the screen projection end device 1 can successfully analyze the message sent by the screen projection end device 2.
Referring to fig. 2, a flowchart of a screen projection method provided by an embodiment of the present invention is shown, where the method is applied to the screen projection device shown in fig. 1. As shown in fig. 2, the method comprises the steps of:
and S110, acquiring a screen projection failure message.
If the media files projected to the screen-projected end equipment by the screen-projected end equipment cannot be displayed due to the incompatibility of the screen-projected protocols, the screen projection is failed.
In an application scenario, a screen projection failure message is generated by a screen projection end device and is sent to the screen projection end device. And in the scene, the screen-projected end equipment generates a corresponding screen-projection failure message according to the error code defined by the screen-projection protocol and returns the screen-projected end equipment.
For example, a certain screen-projected end device only supports a video file in an MP4 format, and when the screen-projected end device sends a video resource address in an m3u8 format to the screen-projected end device, and after the screen-projected end device requests a corresponding video resource from the video resource server according to the video resource address, because the screen-projected end device does not support the video resource in the m3u8 format, at this time, the screen-projected end device generates a corresponding screen-projection failure message according to an error code corresponding to the condition defined by the screen-projection protocol, and returns the screen-projected end device.
In another application scenario, the screen-projection failure message is generated by the screen-projection end device according to the error information (such as an error code) returned by the screen-projection end device. For example, after receiving the error code returned by the screen-projected device, the screen-projected device generates a corresponding screen-projection failure message according to the definition of the error code in the screen-projection protocol used by the screen-projected device.
And S120, sending the screen projection failure message to the server, so that the server obtains the target screen projection protocol information used by the screen projection end equipment with screen projection failure according to the screen projection failure message.
The screen projection end equipment obtains a screen projection failure message and then sends the screen projection failure message to the server end, and the server end obtains parameter information of a target screen projection protocol used by the screen projection object (namely the screen projection end equipment) according to the screen projection failure message and sends the parameter information to the screen projection end equipment sending the screen projection failure message.
The server side can be a service side which can enable the screen projection side equipment to project the screen to the screen projection side equipment. For example, the screen projection end device and/or the screen projected end device is screen projection software installed for implementing screen projection operation, and the service end in this text is a background service end of the screen projection software.
And S130, receiving target screen projection protocol information sent by the server, and taking the target screen projection protocol information as a basis for sending screen projection contents to the screen projection end equipment by the screen projection end equipment.
And the screen projection terminal equipment receives target screen projection protocol information sent by the service terminal through a wireless network such as a WiFi network. And taking the target screen projection protocol information as a basis for sending screen projection contents to the screen projection end equipment by the screen projection end equipment. Namely, the screen projection end equipment sends screen projection content to the screen projection end equipment according to the target screen projection protocol information.
In an application scenario of the present invention, the same screen projection terminal may perform the screen projection requirements on different screen projection terminal devices at different times.
In order to achieve the purpose, the screen projection end device receives target screen projection protocol information sent by the server end, stores the target screen projection protocol information into the screen projection end device, reads the target screen projection protocol information corresponding to the screen projection end device from the screen projection end device when the screen is projected to the screen projection end device again, and sends screen projection content to the screen projection end device according to the target screen projection protocol information.
In the method, the screen projection protocol content in the screen projection end equipment does not need to be modified, and the screen projection end equipment only needs to acquire the target protocol parameter matched with the currently projected screen end equipment, so that the screen projection end equipment can adapt to any one projected screen equipment.
The following describes, with reference to fig. 3, a process of storing, by the screen projection device, target screen projection protocol information issued by the server:
s1311, analyzing the target screen projection protocol information to obtain target protocol parameters.
After receiving the target screen-casting protocol information returned by the server, the screen-casting end equipment analyzes the target screen-casting protocol information to obtain the protocol parameters carried in the target screen-casting protocol information, namely the target protocol parameters.
For example, the target screen-casting protocol information issued by the server indicates that the screen-casting device only supports the video file format of the MP4 format, and in this case, the screen-casting device analyzes the target screen-casting protocol information to obtain a target protocol parameter of MP 4.
And S1312, storing the target protocol parameters and the corresponding equipment identification of the screen-projected equipment.
In a possible implementation manner of the present invention, the key-value may be stored in a key-value manner, for example, the key value is a device identifier of the screen-projected device, and the corresponding value is a target protocol parameter.
In another possible implementation manner of the present invention, the storage may be performed in a table manner, for example, one column is a device identifier of the screen-projected device, and the other column is the target protocol parameter, where the mapping relationship is embodied in that the device identifier of the screen-projected device having the mapping relationship is stored in the same row as the target protocol parameter.
In another application scenario of the present invention, the screen-projected device of the screen-projecting device does not change basically, for example, the screen-projecting device is only used at home, and in such a scenario, after receiving the target screen-projecting protocol information returned by the server, the screen-projecting device directly modifies the protocol content of the screen-projecting protocol used by the screen-projecting device according to the target screen-projecting protocol information. As shown in fig. 4, the process of modifying the screen-casting protocol by the screen-casting device according to the target screen-casting protocol information is as follows:
s1321, analyzing the target screen projection protocol information to obtain the parameter type and the parameter value of the target protocol parameter.
After receiving the target screen projection protocol information issued by the server, the screen projection end equipment analyzes the target screen projection protocol information to obtain a target protocol parameter used by the screen projection end equipment, and further obtains the parameter type and the parameter value of the target protocol parameter.
S1322, modifying the parameter value of the parameter with the same type as the parameter in the screen projecting protocol of the screen projecting end equipment into the parameter value of the target protocol parameter to obtain the modified screen projecting protocol.
And the screen projection end equipment modifies the parameter value of the parameter with the same type as the target protocol parameter in the screen projection protocol used by the equipment into the parameter value of the target protocol parameter to obtain the modified screen projection protocol.
For example, after the screen projection end device obtains the target protocol parameter, the class including the target protocol parameter in the screen projection protocol is modified, that is, the parameter value in the class including the protocol parameter in the screen projection protocol of the screen projection end device is directly replaced by the parameter value of the target protocol parameter, so as to obtain the modified screen projection protocol.
The screen projection end device can project the screen to the screen projection end device according to the modified screen projection protocol, namely, the screen projection content which accords with the modified screen projection protocol is sent to the screen projection end device.
In the method, the screen projection end equipment directly modifies the screen projection protocol used by the screen projection end equipment, and the method is suitable for the scene that the screen projection end equipment basically does not change.
According to the screen projecting method provided by the invention, the screen projecting end equipment can acquire the target screen projecting protocol information used by the screen projecting end equipment from the server end, and dynamically adjust the basis for projecting the screen to the screen projecting end equipment according to the target screen projecting protocol information, so that the screen projecting range of the screen projecting end equipment is expanded, and the screen projecting success rate is improved.
Referring to fig. 5, a flowchart of another screen projection method provided in the embodiment of the present invention is shown, where the method will focus on a process in which a screen projection end device sends screen projection content to a screen-projected end device by using a stored target screen projection protocol parameter. As shown in fig. 5, the method may include the steps of:
and S210, the screen projection end device reads the target protocol parameters associated with the screen projection end device according to the device identification of the screen projection end device.
In an application scenario of the present invention, after the screen projection end device fails to project a screen to the screen-projected end device, the communication connection between the screen-projected end device and the screen-projected end device is not disconnected.
In another application scenario of the present invention, after the screen projection end device fails to project a screen to the screen projection end device, the communication connection between the screen projection end device and the screen projection end device is disconnected, and in this case, the screen projection end device needs to first determine whether the target protocol parameter of the screen projection end device is stored.
In an embodiment of the present invention, a device list is stored in the screen-projection-end device, and all devices in the device list are device identifiers of the screen-projection-end device, in which corresponding target protocol parameters are stored in the screen-projection-end device.
After the connection between the screen projection end equipment and the screen projection end equipment is established, the screen projection end equipment can search whether the equipment list contains the equipment identification of the screen projection end equipment or not; and if so, continuously reading the target protocol parameters associated with the screen-projected end equipment according to the mapping relation between the equipment identification of the screen-projected end equipment and the target protocol parameters.
For example, the device identifier of the screen-projected device and the corresponding target protocol parameter stored in a key-value manner are searched for a value of the device identifier of the screen-projected device, and data in the value, that is, the target protocol parameter, is read.
And S220, the screen projection end equipment acquires the content to be projected.
The content to be displayed can be specifically the content to be displayed, or can also be a source file address corresponding to the content to be displayed, and the device at the screen-projected end acquires and displays the corresponding content according to the source file region.
And S230, converting the content to be screen-projected into target screen-projected content based on the target protocol parameter.
And for the condition that the content to be subjected to screen projection is the content to be displayed, converting the content to be subjected to screen projection into target screen projection content meeting the parameter requirements of a target protocol.
And sending the source file address of the content to be projected meeting the requirement of the target protocol parameters to the screen-projected end equipment under the condition that the content to be projected is the source file address, so that the screen-projected end equipment can obtain corresponding target screen-projected content according to the source file address.
For example, it is determined that the screen-projected device only supports the video file format of MP4 format according to the target protocol parameters, the screen-projected device sends the source file address of the video file of MP4 format to the screen-projected device, so that the screen-projected device obtains the corresponding video file according to the source file address and plays the video file on the screen-projected device.
And S240, sending the target screen projection content to the screen projection end equipment.
And the screen projection end equipment sends the target screen projection content to the screen projection end equipment so that the screen projection end equipment can successfully display the target screen projection content.
In the screen projection method provided by this embodiment, when the screen projection end device projects a screen to the screen-projected end device, the target protocol parameter corresponding to the screen-projected end device is read from the screen-projected end device. And converting the content to be screen-projected into target screen-projected content according to the target protocol parameters, and sending the target screen-projected content to the screen-projected end equipment, so that the screen-projected end equipment successfully projects a screen to the screen-projected end equipment, and the screen-projected success rate of the screen-projected end equipment is improved.
