Figure 1 shows a flow chart of a video encoding adaptation method provided by an embodiment of the present application. The video encoding adaptation method provided by an embodiment of this application can be performed by a video encoding adaptation device, and the video encoding adaptation device can It is realized by means of hardware and/or software, and is integrated in a video coding adaptation device (such as a mobile phone, a tablet, a computer, etc.).

The video coding adaptation method performed by the video coding adaptation device is taken as an example for description below. Referring to Figure 1, the video coding adaptation method includes:

S101: Send a quality query request to the server according to the device type information, to query whether the server stores hard-coded quality information corresponding to the device type information.

The device type information provided in this embodiment is used to indicate the device type corresponding to the video encoding adaptation device, and the device type information may be one of the device model, processing chip, operating system, and system version or a combination of several. Generally, different video encoding adaptation devices with the same device type information have similar encoding and processing capabilities for the same video file due to the same combination of one or more of the device model, processing chip, operating system, and system version. , the hard-coded quality information obtained from the hard-coded quality detection of the test video file by other video coding adaptation devices corresponding to the same device type information can reflect the hard-coded quality information obtained by the current video coding adaptation device from the hard-coded quality detection of the test video file Hard-coded quality information.

Wherein, the hard-coded quality information is recorded in the server based on the corresponding device type information, and the hard-coded quality information recorded in the server may be obtained by testers performing hard-coded quality detection on test video files based on different types of devices, or by other The video encoding adaptation device performs hard-coded quality inspection on the test video file and uploads it.

Optionally, the hard-coded quality information can be recorded in the form of a map, that is, the device type information is used as a key, and the corresponding hard-coded quality information is used as a value, and the hard-coded quality information and device type information are encapsulated in a key-value pair. After receiving the quality query request sent by the video coding adaptation device, the server uses the device type information carried in the quality query request as a key, and matches the same key in the record file of hard-coded quality information to find the hardware Encode quality information.

Exemplarily, when it is necessary to request hard-coded quality information from the server to determine the video encoding method, determine the device type information corresponding to the current video encoding adaptation device, and generate a quality query request according to the device type information.

After receiving the quality query request sent by the video coding adaptation device, the server determines the device type information carried in the quality query request, and checks whether the hard-coded quality corresponding to the device type information is saved in the record file of the hard-coded quality information. information, and return the corresponding quality query result to the video coding adaptation device.

For example, when the server finds the hard-coded quality information of the same device type information, it returns a quality query result indicating that the query is successful to the video coding adaptation device; The video coding adaptation device returns a quality query result indicating that the query fails.

S102: Determine to obtain the hard-coded quality information from the server based on the quality query result returned by the server, or perform hard-coded quality detection according to the test video file to obtain the hard-coded quality information.

Exemplarily, after receiving the quality query result returned by the server, determine the acquisition method of the hardware coding quality according to the quality query result, that is, determine whether to obtain the hard-coded quality information from the server, or perform hard-coded quality detection according to the test video file to obtain the hard-coded quality information. quality information.

For example, when the quality query result indicates that the query is successful, it is determined to obtain the hard-coded quality information from the server. In one embodiment, if the quality query result indicates that the query is successful, the direct query result may carry corresponding hard-coded quality information. When the quality query result indicates that the query fails, it is determined to perform hard-coded quality detection according to the test video file to obtain hard-coded quality information. The test video file can be a test file provided by the server, or a test file previously stored locally by a video encoding adaptation device, and the test video files used by different video encoding adaptation devices for hard-coded quality inspection are the same test Files, select test video files with the same content for encoding, to ensure that the evaluation of video hard-coded quality is not affected by content differences, and to ensure the consistency and objectivity of hard-coded test results between different video encoding adaptation devices.

S103: Determine a video encoding method according to the hard-coded quality information.

Exemplarily, after the hard-coded quality information is obtained, the video coding mode used when encoding the video is determined according to the hard-coded quality information. Wherein, the video coding method includes a hard coding method using a hardware encoder and a soft coding method using a software encoder. It is understandable that in real-time coding, hard coding is faster than soft coding, with lower power consumption, higher coding frame rate, and smoother picture playback. If the hardware performance allows or is sufficient, the quality of video coding can be guaranteed. Under the premise, the encoding effect of the hard-coding method is better than that of the soft-coding method. When the hard-coded quality information indication meets the set conditions, the hard-coded method is preferred to improve the video coding frame rate, reduce the energy consumption of coding, and improve user experience.

In one embodiment, after the video encoding method is determined, when the video needs to be encoded later (for example, when the anchor device needs to upload the video stream generated during the live broadcast to the server), the video will be encoded according to the determined video encoding method . Optionally, after the video encoding method is determined, the determined video encoding method can be recorded, and when the corresponding application is subsequently restarted, the previously determined video encoding method based on the hard-coded quality information will be used, or when the device is detected When the type information changes (such as hardware or system version update), clearly record the video encoding method and/or perform hard-coded quality inspection based on the test video file again, or not record the determined video encoding method, corresponding to each restart When using the application, the video encoding method is re-determined based on the hard-coded quality information.

As mentioned above, by recording the hard-coded quality information corresponding to different device type information in the server, and sending a quality query request to the server according to the device type information, when the hard-coded quality information corresponding to the device type information is recorded in the server, directly from the server To obtain the hard-coded quality information of this device type, there is no need to perform hard-coded quality inspection based on the test video file. If the hard-coded quality information corresponding to the device type information is not recorded in the server, use the test video file to perform hard-coded quality inspection. The hard-coded quality information is measured, and then the video coding method is determined according to the obtained hard-coded quality information, so as to effectively improve the adaptation efficiency of the video coding method and ensure the video coding quality and user experience.

On the basis of the above-mentioned embodiments, FIG. 2 shows a flowchart of another video coding adaptation method provided by the embodiment of the present application. The video coding adaptation method is the embodiment of the above-mentioned video coding adaptation method. Referring to Figure 2, the video encoding adaptation method includes:

S201: Determine whether hard-coded quality information is stored locally.

The video coding adaptation device provided in this embodiment performs video coding through an installed application program (such as live video software), and after the video coding adaptation device starts the application program, it will determine the video coding method at an appropriate time. For example, when the application program is started for a set duration (for example, 5s), or when a functional module that requires video encoding is enabled (for example, the host turns on the live broadcast function), it is determined that the video encoding method needs to be determined through hard-coded quality information.

In this embodiment, the hard-coded quality information stored locally in the video coding adaptation device is preferentially used, and the hard-coded quality information is requested from the server when the hard-coded quality information is not stored locally. Exemplarily, when it is necessary to determine the video encoding method, search for hard-coded quality information locally, if there is hard-coded quality information locally, then jump to step S202, if there is no hard-coded quality information locally, then jump to step S203 .

In one embodiment, locally stored hardcoded quality information may be associated with device type information. When determining whether there is hard-coded quality information stored locally, the hard-coded quality information can be verified based on the latest device type information of the video coding adaptation device. If the latest device type information corresponds to the found hard-coded quality information If the type information is consistent, it is determined that the hard-coded quality information is saved locally. If the latest device type information is inconsistent with the device type information corresponding to the found hard-coded quality information (for example, the video encoding adaptation device has been repaired or upgraded to change the hardware or system) version, resulting in inconsistent device type information), it is considered that the hard-coded quality information is not saved locally, and the wrong hard-coded quality information is deleted.

S202: In response to the hard-coded quality information being stored locally, determine to determine a video encoding method directly according to the hard-coded quality information.

Exemplarily, when the hard-coded quality information is stored locally, it can be determined that the method of determining the video encoding method is to directly determine the video encoding method based on the local hard-coded quality information, and there is no need to request the hard-coded quality information from the server or to test Video files have hard-coded quality checks. The hard-coded quality information stored locally is compared with the coding quality threshold, and when the hard-coded quality information reaches the coding quality threshold, it is determined that the video coding method is hard-coding, and when the hard-coded quality information does not reach the coding quality threshold When the quality threshold is set, the video encoding mode is determined to be soft encoding. When it is determined that the video encoding mode is determined directly according to the hard-coded quality information, jump to step S208.

Wherein, the hard-coded quality information stored locally may be the hard-coded quality information obtained from the server when the video coding adaptation device determined the video coding mode last time, or the hard-coded quality information obtained by performing hard-coded quality detection on the test video file The hard-coded quality information may also be the hard-coded quality information sent by the server actively according to the device type information of the video coding adaptation device.

S203: In response to no hard-coded quality information stored locally, determine to send a quality query request to the server according to the device type information.

Exemplarily, when there is no hard-coded quality information saved locally, it is necessary to send a quality query request to the server according to its own device type information to determine whether to obtain the hard-coded quality information from the server or perform hard-coded quality detection based on the test video file way to get hard-coded quality information.

S204: Send a quality query request to the server according to the device type information, to query whether the server stores hard-coded quality information corresponding to the device type information.

S205: In response to the server returning a successful quality query result, acquire the queried hard-coded quality information from the server.

Exemplarily, when the server returns a successful quality query result, the quality query hard-coded quality information corresponding to the device type information is directly obtained from the server, and jumps to step S208, and the video is directly determined according to the hard-coded quality information returned by the server. Encoding.

S206: In response to the server returning a quality query result of query failure, obtain a test video file from the server, and perform hard-coded quality detection on the test video file to obtain hard-coded quality information.

Exemplarily, when the server returns the quality query result of query failure, that is, there is no previous video coding adaptation device of the same device type to perform hard-coded quality detection based on the test video file and upload the corresponding hard-coded quality information, in order to ensure video coding quality , requires hard-coded quality checks locally.

As shown in the schematic diagram of a hard-coded quality inspection process provided in Figure 3, when the hard-coded quality inspection is performed on the test video file to obtain the hard-coded quality information, it specifically includes:

S2061: Encode the test video file in a hard-coded manner to obtain a video encoding result.

S2062: Calculate hard-coded quality information for hard-coding the test video file according to the video coding result.

Exemplarily, download the test video file according to the video file address provided by the server, and use the local hardware encoder to encode the test video file in a hard-coded manner to obtain the video encoding result, and use the video encoding result to calculate the test video file Hardcoded quality information is hardcoded.

In one embodiment, after hard-coding the hard-coded quality information of the test video file, the hard-coded quality information is saved locally, and when the corresponding application is subsequently opened, the video encoding can be directly determined according to the locally recorded hard-coded quality information. mode to improve the adaptation efficiency of the video coding mode.

S207: Save the hard-coded quality information to the server based on the device type information.

Exemplarily, after hard-coding the hard-coded quality information on the test video file, based on the device type information of the current video coding adaptation device, the locally calculated hard-coded quality information is uploaded to the server, and the server saves the hard-coded quality information based on the device type information The hard-coded quality information is used for other video coding adaptation devices of the same type to obtain the hard-coded quality information based on the same device type information to adapt the video coding method.

In a possible embodiment, the hard-coded quality information and the corresponding device type information are recorded in the form of a map, that is, after the hard-coded quality information is calculated, the device type information is used as the key and the hard-coded quality information is used as the value to construct Key-value pairs are packaged into a map and uploaded to the server, which facilitates the server to record the correspondence between hard-coded quality information and device type information, and improves the query matching efficiency of hard-coded quality information and device type information.

S208: Determine a video encoding method according to the hard-coded quality information.

In a possible embodiment, the video encoding mode adopted may be determined according to a comparison result between the hard-coded quality information and a preset encoding quality threshold. Based on this, as shown in Figure 4, as shown in a flow diagram of determining a video encoding method, this solution specifically includes when determining a video encoding method based on hard-coded quality information:

S2081: Compare the hard-coded quality information with a coding quality threshold.

S2082: In response to the comparison result that the hard-coded quality information reaches the coding quality threshold, determine that the video coding mode is the hard-coded mode.

S2083: In response to the comparison result that the hard-coded quality information does not reach the coding quality threshold, determine that the video coding mode is a soft coding mode.

Exemplarily, after the hard-coded quality information corresponding to the current device type information is obtained, the hard-coded quality information is compared with the coding quality threshold, and a corresponding comparison result is obtained.

In one embodiment, when the comparison result indicates that the hard-coded quality information reaches the coding quality threshold, it can be determined that the coding quality of the hard-coded video under the current hardware configuration can meet the set coding quality requirement, and then the video coding method is determined as Hardcoded way.

When the comparison result indicates that the hard-coded quality information does not reach the coding quality threshold, it can be determined that the coding quality of hard-coding the video under the current hardware configuration does not meet the set coding quality requirements. For the encoding effect of the video, it is necessary to determine the video encoding method as a soft encoding method.

In one embodiment, the hard-coded quality information is one or a combination of objective quality indicators such as peak signal-to-noise ratio (PSNR), structural similarity (SSIM), and video multi-method assessment fusion (VMAF). Correspondingly, the encoding quality threshold is also configured as one or a combination of objective quality index thresholds such as peak signal-to-noise ratio threshold, structural similarity threshold, and video multi-method evaluation fusion threshold.

Take the video encoding adaptation device configured on the mobile phone, tablet and other live broadcast equipment (video encoding adaptation equipment) used by the anchor as an example. (for example, 3 to 5 seconds), the live broadcast device first judges whether there is hard-coded quality information stored locally. If there is hard-coded quality information stored locally, it directly compares the hard-coded quality information If the information reaches the comparison result of the encoding quality threshold, set the video encoding method of the live broadcast program to hard-coding mode. If the hard-coded quality information does not reach the comparison result of the encoding quality threshold, set the video encoding method of the live program to soft encoding mode .

If there is no hard-coded quality information saved locally, a quality query request is sent to the server according to the device type information of the live broadcast device. If the server returns a quality query result indicating that the query is successful, obtain the hard-coded quality information corresponding to the device type information from the server, and compare the hard-coded quality information with the coding quality threshold. If the hard-coded quality information reaches the coding quality threshold If the comparison result, set the video coding method of the live broadcast program to hard coding, if the hard coded quality information does not reach the comparison result of the coding quality threshold, set the video coding method of the live broadcast program to soft coding.

And when the server returns the quality query result indicating query failure, the video file address provided by the server is sent to the live broadcast program, the test video file is downloaded by the live program based on the video file address, and the test video file is hard-coded by the live program using a hardware encoder. Encode to obtain the video encoding result, and calculate the hard-coded quality information based on the video encoding result, save the hard-coded quality information locally, and encapsulate the hard-coded quality information and device type information into a map and upload it to the server for storage. In one embodiment, the hard-coded quality information saved locally is compared with the coding quality threshold, and if the hard-coded quality information reaches the comparison result of the coding quality threshold, the video coding method of the live program is set to the hard-coded method, if If the comparison result of the hard-coded quality information does not reach the coding quality threshold, configure the video coding method of the live program as a soft coding method.

Subsequent anchors enable the live broadcast function of the live program, the live program encodes the video information collected by the camera based on the determined video encoding method to obtain the encoded video information, and uploads the encoded video information to the corresponding server, and the server sends the encoded video information to the viewer's device. video information. After receiving the coded video information, the viewer device can decode the coded video information and play the corresponding video.

As mentioned above, by recording the hard-coded quality information corresponding to different device type information in the server, and sending a quality query request to the server according to the device type information, when the hard-coded quality information corresponding to the device type information is recorded in the server, directly from the server To obtain the hard-coded quality information of this device type, there is no need to perform hard-coded quality inspection based on the test video file. If the hard-coded quality information corresponding to the device type information is not recorded in the server, use the test video file to perform hard-coded quality inspection. Obtain the hard-coded quality information, and then determine the video coding method according to the obtained hard-coded quality information, effectively improve the adaptation efficiency of the video coding method, and ensure the video coding quality and user experience. At the same time, when the server queries the hard-coded quality information of the same device type information, it can directly request the hard-coded information from the server, and there is no need to perform hard-coded quality inspection on the test video file locally, which improves the efficiency of video coding adaptation. After the hard-coded quality inspection of the test video file is performed locally to obtain the hard-coded quality information, the hard-coded quality information is uploaded to the server based on the corresponding device type information. When other devices of the same type need to determine the video encoding method, they can directly obtain the hard-coded quality information from the server. Acquire the corresponding hard-coded quality information to adapt to the video encoding method, further improving the efficiency of video encoding adaptation.
