Detailed Description
In order to make the objects, technical solutions and advantages of the present disclosure more apparent, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step based on the embodiments in the description belong to the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a three-dimensional image transmission method based on a spread network processor according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
s101, acquiring a desktop image of a local client according to an instruction from a remote client.
The instruction of the remote client may be an instruction of performing desktop virtualization, which is input by a user at the remote client. And after receiving the instruction of the remote client, acquiring the desktop image of the local client.
And S102, directly supplying the physical display card of the physical server corresponding to the local client to the virtual machine corresponding to the local client for use in a preset transmission mode.
In this embodiment of the application, the preset transmission mode may be a transparent transmission mode, and the physical graphics card of the physical server corresponding to the local client is directly provided to the virtual machine for use through the transparent transmission mode.
Transparent transmission refers to that the communication is only responsible for transmitting the transmitted content from a source address to a destination address regardless of the transmitted service content, and no change is made to the content of the service data. And a transparent transmission mode is adopted, so that the method has the advantage of high reliability.
Step S102 may be executed before S101, or may be executed after S101, and is not limited in the embodiment of the present application. In addition, in the embodiment of the present application, the preset transmission method is not limited, and other transmission methods may be selected, and the preset transmission method may be modified according to actual situations.
Because the virtual display card of the virtual machine can only obtain a two-dimensional desktop image, the virtual display card does not support a three-dimensional desktop image. Therefore, the physical display card of the physical server is provided for the virtual machine to use, and the three-dimensional desktop image can be acquired.
And S103, under the condition that the desktop image is the three-dimensional image, sending the desktop image data to a physical display card of the virtual machine.
In this application, the acquired desktop image may be analyzed first to determine whether the desktop image is a three-dimensional image. And under the condition that the desktop image is a three-dimensional image, the desktop image data can be sent to a physical display card of the virtual machine.
It should be noted that the physical graphics card of the virtual machine is obtained in step S102. By the scheme, the problem that the desktop image obtained by the virtual display card of the virtual machine can only be a two-dimensional image when desktop virtualization is carried out by adopting a spice protocol in the prior art is avoided, and the three-dimensional desktop image can be obtained.
And S104, sending the desktop image data in the physical display card to the spice-server through the virtual serial port of the virtual machine.
Because the serial port has a specific serial port communication protocol, in some embodiments of the application, format conversion needs to be performed on the desktop image data first, and the desktop image data after the format conversion corresponds to the communication protocol of the virtual serial port.
It should be noted that, the correspondence means that the data format of the desktop image data after format conversion conforms to the communication protocol of the virtual serial port.
Moreover, the virtual machine may have a plurality of virtual serial ports, so that format conversion of the desktop image data requires a virtual serial port for communication with the first selected virtual serial port.
In some embodiments of the application, the desktop image data in the physical display card is sent to the spice-server through a virtual serial port of the virtual machine, and the method can be implemented in the following manner:
a preset image capturing program in the virtual machine captures desktop image data from the physical display card;
and sending the captured desktop image data to the spice-server through a virtual serial port of the virtual machine.
In some embodiments of the present application, the predetermined grapple program may be a mirror driver (mirrordriver). Because the mirror image drive is carried by the system, the mirror image drive is convenient to use, and the complexity of the system can be reduced.
That is to say, the desktop image data is captured from the physical display card of the virtual machine through a preset image capture program in the virtual machine, and the desktop image data is sent to the spice-server through the virtual serial port. By the scheme, the desktop image data can be acquired from the physical display card of the virtual machine.
It should be noted that the virtual serial port of the virtual machine is configured in advance, and the configured virtual serial port may be consistent with the serial port of the physical server.
S105, the spice-server compresses the desktop image data based on a gzip compression algorithm in the spread processor.
In the description of the application, the spice-server may compress the desktop image data directly based on a gzip compression algorithm built in the Roc processor, and then send the compressed desktop image data to the remote client. On one hand, the desktop image data is compressed and then transmitted, and the transmission efficiency can be improved on the premise of not losing useful information. On the other hand, a built-in gzip compression algorithm in the spread processor is directly adopted, so that the method is simple, convenient and fast.
It should be noted that, in the embodiment of the present application, the gzip compression algorithm in the spread spectrum processor is not limited to be used, and other compression algorithms may also be used.
And S106, the spice-server sends the compressed desktop image data to the remote client through a spice protocol display channel.
The display channel of the spice protocol is used for realizing the communication between the spice-server and the remote client.
In this application, in the process of obtaining the three-dimensional desktop image data obtained by the physical graphics card through the virtual serial port of the virtual machine, the spice-server may interrupt information interaction with the virtual graphics card of the virtual machine, that is, may not receive the two-dimensional desktop image data transmitted by the virtual graphics card any longer. After the spice-server receives the three-dimensional desktop image data, the spice-server can also receive two-dimensional desktop image data transmitted by the virtual display card. By the technical scheme, the three-dimensional desktop image data sent by the virtual serial port is supported to be processed on the basis of being compatible with the original data transmission mode.
S107, the remote client decompresses the received compressed desktop image data to obtain the desktop image data.
In this application, the compressed desktop image data may be decompressed through a decompression algorithm corresponding to the gzip compression algorithm, so that the remote client obtains the decompressed desktop image data.
And S108, the remote client generates a corresponding drawing board according to the decompressed desktop image data, renders the image, and obtains and displays the desktop image.
It should be noted that the received desktop image data may include a format of the desktop image set according to a preset setting, where the format may refer to a size, a resolution, and the like of the desktop image displayed on the remote client.
The remote client can determine the format of the desktop image according to the decompressed desktop image data to generate a drawing board with corresponding size and resolution, and then perform image rendering on the drawing board according to the desktop image data to generate the desktop image.
In some embodiments of the present application, if the desktop image obtained in S101 is a two-dimensional image, the two-dimensional desktop image may be obtained through a virtual graphics card of a virtual machine according to the prior art, so as to complete desktop synchronization. The desktop synchronization can also be realized according to the technical scheme provided by the application specification, and the desktop virtualization mode of the two-dimensional desktop image is not limited in the embodiment of the application.
It should be noted that, when the desktop image is a two-dimensional image, desktop virtualization may also be implemented through the above scheme, that is, when the desktop image is a two-dimensional image, the virtual machine sends the acquired two-dimensional desktop image data to a physical graphics card of the virtual machine, and then completes desktop virtualization in the manner of steps S104 to S108. Therefore, in the technical scheme provided by the embodiment of the application, the transmission of the three-dimensional desktop image can be realized, and the transmission of the two-dimensional desktop image can also be realized.
According to the three-dimensional image transmission method based on the spread-spectrum processor, data of the three-dimensional desktop image can be obtained through the physical display card which is directly provided for the virtual machine to use, the data of the three-dimensional desktop image in the physical display card is sent to the remote client side through the virtual serial port and the spice-server of the virtual machine, and the remote client side can display the three-dimensional desktop image to achieve desktop virtualization. Based on the technical scheme, desktop synchronization of three-dimensional application can be realized when desktop virtualization is performed by adopting a spice protocol, the realization complexity is low, the compatibility is good, and the user experience is improved.
