Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The embodiment of the present disclosure provides a coding acceleration method, which is applied to a source device, and as shown in fig. 2, the method includes the following steps:

step 201, when it is detected that the receiving end device is accessed to the display device, obtaining the current display parameters of the display device.

Wherein the current display parameters include a current display resolution and a current display frame rate.

For example, the source device includes a virtual machine or a physical machine, the virtual machine runs on a cloud server, the physical machine may be a cloud server, the virtual machine or the physical machine establishes a connection with the receiving end device, and when the receiving end device corresponding to the virtual machine or the physical machine accesses a display device (for example, a display), the receiving end device feeds back the detected Extended Display Identification Data (EDID) to the corresponding virtual machine or physical machine, so that the virtual machine or the physical machine obtains current display parameters of the display device, where the current display parameters include a current display resolution and a current display frame rate.

It should be noted that the resolution and the display frame rate of the display device set by the user may be the maximum display resolution and the maximum display frame rate of the display device, or may be values smaller than the maximum display resolution and the maximum display frame rate, which is not limited in this disclosure.

It should be noted that the purpose of obtaining the current display resolution and the current display frame rate is to implement super-resolution display, for example, a 4K144 display is accessed on a receiving end device, whereas in terms of the existing capability, the S end can only display the resolution and the frame rate of 1K 144 at most, and at this time, if the receiving end device performs resolution and frame rate negotiation with the S end, it can only negotiate the resolution and the frame rate of 1K 144 with the S end at most, which obviously cannot meet the display requirement of the display of the receiving end device, and therefore, the main purpose of the present disclosure is to accelerate by a coding server, so that the receiving end device can negotiate the resolution and the frame rate (e.g., 4K144) as high as possible.

Step 202, determining whether the physical display card supports the display requirement of the display device according to the current display parameter and all display mode parameters supported by the physical display card of the source device.

Wherein the display mode parameters include a resolution and a frame rate of the physical display card.

For example, when the current display parameter of the display device is obtained, searching an effective mode list of a physical display card of the source device, as shown in fig. 3, where all display mode parameters of the physical display card are stored in the effective mode list, and the display mode parameters include a resolution and a frame rate, therefore, if the current display resolution and the current display frame rate of the display device are in the effective mode list of the physical display card of the source device, it is determined that the physical display card supports the display requirement of the display device; if the current display resolution and the current display frame rate of the display device are not found in the effective mode list, it indicates that the physical display card cannot support the display requirement of the display device.

Step 203, when it is determined that the physical display card does not support the display requirement of the display device, sending a display card resource request to an encoding server, so that the encoding server sends a target display card resource to the source device.

Optionally, acquiring the current resource occupancy rate of the physical display card; and when the current resource occupancy rate is determined to be greater than a first preset threshold value, sending the video card resource request to the coding server.

Illustratively, when it is determined that the physical graphics card does not support the display requirement of the display device, the current resource occupancy rate of the physical graphics card is continuously monitored, the current resource occupancy rate is compared with a first preset threshold, and when it is determined that the current resource occupancy rate is greater than the first preset threshold, it is indicated that the current remaining graphics card resources of the physical graphics card are insufficient, at this time, a graphics card resource request is sent to the encoding server for requesting graphics card resources, and the encoding server divides the local graphics card resources in advance, for example, by taking 0.1 as a unit, so that when the graphics card resource request is received, a predetermined number of target graphics card resources can be directly allocated to the source end device.

And step 204, receiving the target display card resource sent by the coding server.

Optionally, a first preset unit of display card resources sent by the encoding server each time is received; determining the current resource occupancy rate of the physical display card according to the display card resources of the first preset unit; and sending the current resource occupancy rate to the coding server, so that the coding server determines whether to continuously send the video card resources of the first preset unit to the source end device according to the current resource occupancy rate.

For example, the method for allocating the predetermined number of target video card resources to the source device by the encoding server may specifically adopt the following method: the method comprises the steps that a coding server allocates resources of a first preset unit of display card to a source end device each time, when the source end device receives the resources of the first preset unit of display card, the resources of the first preset unit of display card and the residual resources of a physical display card are added to obtain the current resource occupancy rate of the physical display card, the current resource occupancy rate of the physical display card is fed back to the coding server in real time, when the coding server determines that the current resource occupancy rate of the physical display card is larger than a first preset threshold value, the resources of the first preset unit of display card are allocated to the source end device continuously until the current resource occupancy rate of the physical display card of the source end device is smaller than the first preset threshold value, and the resources of the first preset unit of display card are stopped being allocated to the source end device continuously.

Further, receiving a resource return instruction sent by the coding server; the resource returning instruction is used for indicating that a second preset unit of display card resources are returned to the coding server every time according to a second preset frequency until the current resource occupancy rate is greater than a second preset threshold value; and responding to the resource returning instruction, and returning the display card resources of a second preset unit to the coding server every time according to a second preset frequency until the current resource occupancy rate is greater than a second preset threshold value.

Wherein the second preset threshold is smaller than the first preset threshold; the second preset unit is smaller than the first preset unit.

And 205, encoding the data to be encoded according to the target display card resources and the resources of the physical display card.

For example, when receiving the target graphics card resource, the source device may encode the data to be encoded according to a combination of the remaining resource of the physical graphics card and the target graphics card resource, so as to accelerate encoding.

Further, as shown in fig. 4, when it is determined that the physical graphics card supports the display requirement of the display device, the method further includes the following step 206:

and step 206, when it is determined that the physical display card supports the display requirement of the display device, encoding data to be encoded according to the resource of the physical display card.

For example, when the source device determines that the physical display card supports the display requirement of the display device, it indicates that the display card resources of the physical display card are sufficient, and at this time, the source device may encode the display card resources of the physical display card.

Further, as shown in fig. 5, after the step 205 is executed, the method further includes the following steps:

and step 207, determining whether the current display parameters are changed.

For example, if a user changes a display device connected to the receiving device or modifies display parameters of the display device, the current display parameters of the display device may be changed.

And 208, when the current display parameters are determined to be changed, determining whether the physical display card supports the display requirements of the display equipment according to the changed current display parameters.

For example, when determining that the current display parameter of the display device changes, the source device needs to search for the changed current display parameter in the valid mode list, and if the changed current display parameter is found in the valid mode list, it indicates that the physical display card supports the display requirement of the display device; if the changed current display parameters are not found in the effective mode list, it indicates that the physical display card cannot support the display requirement of the display device.

Step 209, when it is determined that the physical graphics card supports the display requirement of the display device, sending a graphics card resource release request to the encoding server, so that the encoding server stores the target graphics card resource in a resource pool again.

For example, when it is determined that a physical display card supports a display requirement of a display device, it indicates that the computing power of the source device is sufficient, at this time, a display card resource release request needs to be sent to the encoding server, so that the encoding server releases a target display card resource transferred to the source device when receiving the display card resource release request, the released display card resource returns to the resource pool again, and can be subsequently allocated to other source devices, and meanwhile, the encoding server does not monitor and adjust the display card resource occupancy rate of the physical display card of the source device any more.

It should be noted that, in order to ensure normal communication between the code server and the source device, it is usually required that the source device and the code server are preferably in one network segment, and a gigabit local area network is preferred because high-speed communication is required.

The disclosed embodiment provides a coding acceleration method, which determines whether a display card supports the display requirement of display equipment according to the current display parameters of the display equipment and all display mode parameters supported by the display card of source equipment, and when determining that the display card does not support the display requirement of the display equipment, sends a display card resource request to a coding server, so that the coding server sends a target display card resource to the source equipment, and thus the source equipment can code data to be coded according to the target display card resource and the resource of a physical display card, thereby improving the flexibility of the coding capability of the source equipment under the condition of not replacing the physical display card, and bringing great convenience to a user; with the increase of the computing power requirement of the source-end equipment, only the display card needs to be added in the resource pool of the coding server, and the physical display card does not need to be continuously replaced.

The embodiment of the present disclosure provides a coding acceleration method, which is applied to a coding server, and as shown in fig. 6, the method includes the following steps:

step 601, receiving a display card resource request sent by a source end device.

Step 602, sending a target graphics card resource to the source device, so that the source device encodes data to be encoded according to the target graphics card resource and the resource of the graphics card.

Optionally, a first preset unit of display card resources are sent to the source end device each time according to a first preset frequency; after the display resources of the first preset unit are sent each time, receiving the current resource occupancy rate of the display card sent by the source end device; when the current resource occupancy rate is determined to be greater than the first preset threshold, continuously sending the first preset unit of display card resources to the source end device, and stopping sending the first preset unit of display card resources to the source end device until the current resource occupancy rate is less than the first preset threshold.

Illustratively, the encoding server divides the local video card resources in advance, for example, by 0.1, so that when receiving a video card resource request, the encoding server can allocate a predetermined number of target video card resources to the source end device directly, that is, the encoding server allocates a first preset unit of video card resources to the source end device each time, the source end device adds the first preset unit of video card resources and the remaining resources of the physical video card to obtain the current resource occupancy rate of the physical video card when receiving the first preset unit of video card resources, and feeds back the current resource occupancy rate of the physical video card to the encoding server in real time, when determining that the current resource occupancy rate of the physical video card is greater than a first preset threshold, the encoding server continuously allocates the first preset unit of video card resources to the source end device until the current resource occupancy rate of the physical video card of the source end device is less than the first preset threshold, and stopping continuously allocating the first preset unit of display card resources to the source end equipment. For example, the display device needs to obtain 4K144 display resources, the current resource occupancy rate of the physical display card is 100%, at this time, the display card resources of the encoding server are called to accelerate, the encoding server may divide the display card resources in the resource pool into integer equal parts, give 1 equal part or multiple equal parts to the source device each time, and if the integer equal parts or multiple equal parts are not enough, give 1 equal part or multiple equal parts again until the current resource occupancy rate of the physical display card is lower than a first preset threshold (for example, 80%).

Further, monitoring the current resource occupancy rate of the physical display card; and when the current resource occupancy rate is determined to be smaller than a second preset threshold value, sending a resource return instruction to the source end equipment, and receiving a second preset unit of display card resources returned by the source end equipment.

The resource returning instruction is used for indicating that a second preset unit of display card resources are returned to the coding server every time according to a second preset frequency until the current resource occupancy rate is greater than a second preset threshold value; the second preset threshold is smaller than the first preset threshold; the second preset unit is smaller than the first preset unit.

Illustratively, in the process of encoding by the source end device, the resource occupancy rate of the display card of the source end device is in a dynamic change, so the encoding server needs to continuously monitor the current resource occupancy rate of the physical display card of the source end device in real time, when it is determined that the current resource occupancy rate of the physical display card is smaller than a second preset threshold, it indicates that there is a surplus of resources of the physical display card of the source end device, at this time, a resource return instruction is sent to the source end device, that is, the source end device is controlled to return second preset unit of display card resources to the encoding server, and the current resource occupancy rate of the physical display card is fed back to the encoding server in real time, when it is determined that the current resource occupancy rate of the physical display card is smaller than the second preset threshold, the encoding server continuously controls the source end device to return second preset unit of display card resources to the encoding server until the current resource occupancy rate of the physical display card of the source end device is larger than the second preset threshold, and prohibiting the source terminal equipment from returning the video card resource to the encoding terminal equipment, and storing the returned video card resource in the resource pool by the encoding server. The current resource occupancy rate of the physical display card of the source end equipment can be stabilized between a first preset threshold (80%) and a second preset threshold (60%), namely, the current resource occupancy rate is stabilized in a [ 60%, 80% ] interval, the source end equipment is controlled to return the display card resource which is released to the coding server once the current resource occupancy rate is less than 60%, and the display card resource which is released to the source end equipment is increased once the current resource occupancy rate is greater than 80%, so that the display card resource of the physical display card of the source end equipment can meet the display requirement of the display equipment and can be in a relatively reasonable interval range, and the reasonable utilization of the resource of the coding server is realized.

The disclosed embodiment provides a coding acceleration method, wherein a coding server sends target video card resources to a source end device when receiving a video card resource request sent by the source end device, so that the source end device can code data to be coded according to the target video card resources and the resources of a physical video card, thereby improving the flexibility of the coding capability of the source end device without replacing the physical video card and bringing great convenience to a user; with the increase of the computing power requirement of the source-end equipment, only the display card needs to be added in the resource pool of the coding server, and the physical display card does not need to be continuously replaced.

Step 704, when determining that the current resource occupancy rate is greater than a first preset threshold, the source device sends the video card resource request to the encoding server.

Step 705, the encoding server sends a first preset unit of video card resources to the source end device each time according to a first preset frequency.

Step 706, after the encoding server sends the first preset unit of display resources each time, receiving the current resource occupancy rate of the display card sent by the source end device.

And 707, when determining that the current resource occupancy rate is greater than the first preset threshold, the encoding server continuously sends the first preset unit of video card resources to the source end device, and when determining that the current resource occupancy rate is less than the first preset threshold, the encoding server stops sending the first preset unit of video card resources to the source end device.

Step 708, the coding server monitors the current resource occupancy rate of the physical display card.

Step 709, the coding server sends a resource return instruction to the source end device when determining that the current resource occupancy rate is smaller than a second preset threshold.

Step 710, the source end device responds to the resource return instruction, and returns a second preset unit of video card resources to the encoding server each time according to a second preset frequency until the current resource occupancy rate is greater than the second preset threshold.

Step 711, the source device determines whether the current display parameter changes.

Step 712, when determining that the current display parameter changes, the source device determines whether the physical display card supports the display requirement of the display device according to the changed current display parameter.

Step 713, when determining that the physical display card supports the display requirement of the display device, the source device sends a display card resource release request to the encoding server, so that the encoding server stores the target display card resource in a resource pool again.
