[0025] The following describes exemplary embodiments of the present disclosure in conjunction with the drawings. Various details of the embodiments of the present disclosure are included to assist understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0026] Figure 1 It is a flowchart of a resolution setting method disclosed according to an embodiment of the present disclosure. This embodiment can be applied to the situation where a communication connection is established between a client and the cloud. The method of this embodiment can be executed by a resolution setting device, which can be implemented in a software and / or hardware manner and is specifically configured in an electronic device with a certain data computing ability. The electronic device can be a client device or a server device. Examples of client devices include mobile phones, tablet computers, vehicle-mounted terminals, and desktop computers, etc.

[0027] S110. Receive the resolution to be set sent by the client.

[0028] In the embodiment of the present disclosure, the display control service deployed in the cloud receives the resolution to be set sent by the client through a pre-added resolution receiving interface. Among them, an interface for receiving the resolution is pre-added in the display control service. Correspondingly, an interface for sending the resolution is pre-added in the client to send the resolution to the display control service deployed in the cloud, and the client can also display options of multiple common resolutions to the user so that the user can set the resolution of the cloud desktop by selecting the resolution option. Exemplarily, the resolution options include 1280*720, 1920*1080, 2560*1440, etc.

[0029] S120. Send the resolution to be set to the graphics interface service through the IPC (Inter-Process Communication) interface, so that the graphics interface service sets the resolution of the cloud desktop according to the resolution to be set.

[0030] Among them, the graphics interface service is a service provided by the cloud operating system for cloud desktop image rendering and cloud desktop image output. The graphics interface service includes a resolution setting module for setting the resolution of the cloud desktop. Exemplarily, under the Linux operating system, the graphics interface service is Xserver, and the resolution setting module included in the X server is Xrandr.

[0031] In the embodiment of the present disclosure, IPC (Inter-Process Communication) communication between the display control service and the graphics interface service is pre-implemented. Specifically, an IPC interface is set in the graphics interface service, and the display control service can send the resolution to be set sent by the client to the graphics interface service through the IPC interface, so that the graphics interface service sets the resolution of the cloud desktop according to the resolution to be set.

[0032] Exemplarily, the display control service under the Linux system receives the resolution to be set, which is 1920*1080, sent by the client. Then, the display control service sends the resolution to be set to the graphics interface service, i.e., the X server, through the IPC interface to instruct the X server to set the resolution of the cloud desktop to 1920*1080. Among them, the X server contains a resolution setting module, X randr, for setting the resolution of the cloud desktop. After receiving the resolution to be set sent by the display control service, the X server can directly call the interface of X randr to set the resolution.

[0033] The technical solution of the embodiment of the present disclosure receives the resolution to be set sent by the client, and then sends the resolution to be set to the graphics interface service through the inter-process communication IPC interface, so that the graphics interface service sets the resolution of the cloud desktop according to the resolution to be set, achieving the effect of setting the resolution of the cloud desktop on the client.

[0034] Figure 2 It is a schematic diagram of a resolution setting in the embodiment of the present disclosure. Based on the above embodiment, it is further refined to provide the specific steps of sending the resolution to be set to the graphics interface service through the inter-process communication IPC interface, so that the graphics interface service sets the resolution of the cloud desktop according to the resolution to be set, and the specific steps before sending the resolution to be set to the graphics interface service. The following combines Figure 2 A resolution setting method provided by the embodiment of the present disclosure is described as follows:

[0035] S210. Receive the resolution to be set sent by the client.

[0036] S220. Turn off the video encoder and the collector.

[0037] Among them, the video collector runs in the display control service in the cloud and is used to collect the video images provided by the graphics interface service. The encoder is used to encode the video images and transmit the encoded data to the client.

[0038] In the embodiments of the present disclosure, before setting the resolution, it is necessary to destroy the original FB (Frame Buffer), and reallocate memory for the FB of the new resolution. Therefore, before setting the resolution, the video encoder and the collector are turned off to destroy the original FB, so as to ensure that after the user adjusts the resolution, the server captures and encodes the video image to be displayed at the adjusted resolution. Correspondingly, the client decodes and displays the video image at the adjusted resolution, realizing a fast and smooth switch of the resolution and improving the user experience. Among them, FB is an interface provided by the Linux system for the display device. It abstracts the display buffer and allows upper-layer application programs to directly read and write the display buffer in the graphics mode.

[0039] S230. Taking the resolution to be set as a parameter, call the IPC interface of the graphics interface service, so that the graphics interface service sets the resolution of the cloud desktop to the resolution to be set by calling the resolution setting module.

[0040] In the embodiments of the present disclosure, after turning off the video collector and the encoder, the display control service takes the resolution to be set as a parameter and calls the IPC interface of the graphics interface service to instruct the graphics interface service to set the resolution of the cloud desktop to the resolution to be set by calling the resolution setting module. Specifically, an IPC network communication client is implemented in the display control service, and the resolution to be set is sent to the graphics interface service through a datagram socket. Correspondingly, an IPC communication server is implemented in the graphics interface service to listen for the resolution to be set sent by the display control service through the datagram socket. Further, after receiving the resolution to be set, the graphics interface service adjusts the resolution by calling the resolution setting module. In the embodiments of the present disclosure, under the Linux system, the display control service and the graphics interface service communicate through the UDP (User Datagram Protocol) protocol based on the Unix domain, so that the communication between the display control service and the graphics interface service does not pass through the network card, which can improve the communication efficiency between the two. And by establishing IPC communication between the display control service and the graphics interface service provided by the system, after the display control service receives the resolution to be set sent by the client, it directly calls the graphics interface service to transfer the resolution to be set to the graphics interface service, so that the graphics interface service performs resolution setting, without the need to develop a separate underlying program for setting the resolution, reducing the development cost of the cloud desktop resolution setting function.

[0041] Among them, the resolution setting module first determines whether the to-be-set resolution obtained is legal, that is, whether the parameters provided by the graphics interface service conform to the set rules. When the to-be-set resolution is legal, it records the original resolution currently used, initializes the FB of the to-be-set resolution, reallocates memory for the FB of the to-be-set resolution, and at the same time destroys the FB of the original resolution. Finally, it redraws the image with the to-be-set resolution to obtain an image corresponding to the to-be-set resolution.

[0042] S240. According to the resolution adjustment feedback information obtained through the IPC interface, turn on the video encoder and the collector.

[0043] In the embodiments of the present disclosure, after the graphics interface service sets the resolution of the cloud desktop to the to-be-set resolution, it will send resolution adjustment feedback information to the display control service through the IPC interface. After receiving the resolution adjustment feedback information, the display control service will restart the video encoder and the collector to continue collecting and encoding the video image rendered by the graphics interface service, and push the video stream to the client to resume the video playback or image display of the client.

[0044] The technical solution of the embodiments of the present disclosure first receives the to-be-set resolution sent by the client, and turns off the video encoder and the collector. Then, taking the to-be-set resolution as a parameter, it calls the IPC interface of the graphics interface service, so that the graphics interface service sets the resolution of the cloud desktop to the to-be-set resolution by calling the resolution setting module. Finally, according to the resolution adjustment feedback information obtained through the IPC interface, it turns on the video encoder and the collector and continues to push the video to the client, realizing the setting of the resolution of the cloud desktop on the client.

[0045] Figure 3 It is a schematic diagram of a resolution setting in the embodiments of the present disclosure. Based on the above embodiments, it is further refined to provide the specific steps of receiving the to-be-set resolution sent by the client and the specific steps before sending the to-be-set resolution to the graphics interface service. The following combines Figure 3 A resolution setting method provided by the embodiments of the present disclosure is described as follows:

[0046] S310. Receive the to-be-set resolution from the client based on the TCP protocol.

[0047] In the embodiments of the present disclosure, the client and the display control service in the cloud communicate through the TCP (Transmission Control Protocol) protocol to achieve reliable communication between the two. The display control service receives the to-be-set resolution from the client based on the TCP protocol to adjust the resolution of the cloud desktop for the to-be-set resolution.

[0048] S320. Compare the to-be-set resolution with the original resolution of the cloud desktop. If the to-be-set resolution is different from the original resolution of the cloud desktop, perform the operation of S330.

[0049] In the embodiments of the present disclosure, after receiving the to-be-set resolution sent by the client, the display control service first needs to determine whether resolution setting is required. Only when resolution setting is required, will the to-be-set resolution be sent to the graphics interface service, avoiding re - setting the resolution when the to-be-set resolution is the same as the resolution currently used by the cloud desktop, which causes waste of network resources and system computing resources. Specifically, after receiving the to-be-set resolution, the display control service first obtains the current resolution of the cloud desktop, and then compares the to-be-set resolution with the current resolution. Only when the two are different, is it necessary to re - set the resolution. Specifically, when the to-be-set resolution is the same as the original resolution of the cloud desktop, no resolution setting is performed. When the to-be-set resolution is different from the original resolution of the cloud desktop, perform the operation of sending the to-be-set resolution to the graphics interface service, so that the graphics interface service adjusts the resolution of the cloud desktop according to the to-be-set resolution.

[0050] S330. Send the to-be-set resolution to the graphics interface service through the inter - process communication IPC interface, so that the graphics interface service sets the resolution of the cloud desktop according to the to-be-set resolution.

[0051] The technical solution of the embodiments of the present disclosure first receives the to-be-set resolution from the client based on the TCP protocol, compares the to-be-set resolution with the original resolution of the cloud desktop. When the to-be-set resolution is different from the original resolution of the cloud desktop, perform the operation of sending the to-be-set resolution to the graphics interface service. Finally, send the to-be-set resolution to the graphics interface service through the inter - process communication IPC interface, so that the graphics interface service sets the resolution of the cloud desktop according to the to-be-set resolution, realizing the effect of setting the resolution of the cloud desktop on the client side.
