Description

Method and device for configuring video cover pictures of terminal equipment

Technical Field

The disclosure relates to the technical field of internet, and in particular relates to a method, a device and a system for configuring camera configuration parameters of terminal equipment.

Background

With the vigorous development of the short video and live broadcast industries, various video playing services occupy a large amount of Internet surfing time and network traffic of people. On the consumption side, the video watching jamming condition and clarity greatly influence the consumption experience of the user. For example, in a short video service, a cover picture of a video is the first step of watching the video, and a user selects to search the video through the cover picture and decides whether to watch the video, so that the loading speed of the cover picture of the video greatly influences the consumption experience of the user.

The format of the picture has a great influence on the loading speed. For example, the heif picture format employs a coding format of High Efficiency Video Coding (HEVC), with a compression ratio of 90% less than the commonly used cover picture format jpeg and 30% less than webp. The adoption of the cover picture with the high compression ratio can obviously reduce the time consumption of picture downloading, but HEVC coding complexity is high, and performance problems possibly exist on terminal equipment with certain models, so that the problems of slow picture display and the like are caused.

In the related art, this problem is solved by means of a model blacklist: and adding the models which do not support the decoding of the specific picture format or have poor performance into a blacklist, and only issuing cover pictures in a default general format for the models. This approach may lead to a problem of reduced user experience due to the inability to update the blacklist in time.

Fig. 1 illustrates a system environment implementing a method and apparatus for configuring a video cover picture of a terminal device according to an exemplary embodiment of the present disclosure. As shown in fig. 1, the system environment may include a plurality of terminal apparatuses 100-1, 100-2, … 100-n, a server 200. Here, the terminal device 100 may be a terminal device having a communication function and a camera function, and for example, the terminal device 100 in the embodiment of the present disclosure may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, a netbook, a personal digital assistant (personal digital assistant, PDA), an augmented reality (augmented reality, AR)/a Virtual Reality (VR) device. Various video playing applications may be run on the terminal device 100, such as a short video application, a live application, a social application, a video conferencing application, an online education application, and the like. The terminal device 100 is connected to and communicates with the server 200 through a network while running the applications, thereby using the corresponding video services provided by the server 200.

According to an exemplary embodiment of the present disclosure, the plurality of terminal apparatuses 100-1, 100-2, … 100-n may determine decoding performance for a picture of a specific format by decoding a test picture, and transmit the test result to the server 200 through a network.

For example, for a particular model of smartphone, the server 200 may collect thousands of test data recorded by the smartphone in decoding pictures in the HEIF encoding format, and determine from the collected test data whether the model of smartphone has a better performance for decoding pictures in the HEIF encoding format. A method of configuring a video cover picture performed at a terminal device and a method of determining a video cover picture performed at a server will be described with reference to fig. 2 and 3, respectively.

Fig. 2 illustrates a flowchart of a method of configuring a video cover picture performed by a terminal device according to an exemplary embodiment of the present disclosure. In the following description, a smartphone is described as an example of a terminal device, but the present disclosure is not limited thereto. The method of configuring a video cover picture according to an exemplary embodiment of the present disclosure may be performed by an application installed in a terminal device. For example, the method may be performed at the time of a cold start application, so that the configuration for the video cover picture may be predetermined before the video cover picture is loaded, without affecting the playback of the video.

Specifically, first, in step S210, decoding test result information obtained by performing decoding on a test picture by a terminal device and cover picture request information are transmitted to a server.

Next, in step S220, information about the video cover picture is received from the server, and the video cover picture is acquired according to the received information about the video cover picture.

According to an exemplary embodiment of the present disclosure, the terminal device may transmit the cover picture request information to the server while transmitting the decoding test result information within a predetermined period of time after the cold start, wherein the terminal device does not transmit the decoding test result information any more in response to transmitting the decoding test result information to the server a predetermined number of times or the predetermined period of time elapses.

For example, when the user installs the video application and opens the video application for the first time, the video application may perform decoding for the test picture and generate decoding test result information at step S210. The test picture here may be a picture having at least one format stored in advance in the terminal device. For example, at least one format of the test picture may be stored in the terminal device at the time of installing the application, and the test picture may also be downloaded in advance from the server according to an exemplary embodiment of the present disclosure. In this way, the format of the test picture can be configured at the server end and issued to the terminal equipment, so that the decoding performance can be tested for the terminal equipment more flexibly.

According to an exemplary embodiment of the present disclosure, the format of the picture may include at least an encoding manner of the picture. For example, the format of the test picture may be a HEIF encoded picture, a WEBP encoded picture, or a JPEG encoded picture. It should be understood that the encoding method of the picture is not limited to the above encoding method. The decoding test result information may include at least decoding time-consuming information of the terminal device for a test picture of a certain format. If the tested picture has a plurality of formats, the decodable test result information may include a decoding time-consuming information table corresponding to each format.

According to an exemplary embodiment of the present disclosure, the test pictures may include still pictures and/or moving pictures having at least one format, each having a specific resolution, frame rate, and encoding scheme. Accordingly, the decoding test result information may include information such as model information of the terminal device, encoding mode of the test picture, picture resolution, frame rate, decoding time consumption, and the like. Here, decoding time-consuming refers to time taken from the start of decoding the test picture to the completion of display of the test picture.

It should be understood that the various picture characteristics included in the format of the test pictures mentioned above are merely illustrative, and that one skilled in the art may employ pictures having other characteristics as test pictures according to test needs. It should be understood that the above-mentioned information items included in the decoding test result information are also only illustrative, and those skilled in the art may add or reduce the information items included in the decoding test result information according to the test needs, for example, may add information such as memory occupancy and/or CPU occupancy as the decoding test result information, or may use a test picture of uniform resolution without adding picture resolution information, etc., to which exemplary embodiments of the present disclosure are not limited. For example, if the test picture is a moving picture encoded in the HEIF mode, with a resolution of 1080p and a frame rate of 30fps, the decoding test result information may include model information of the terminal device, the encoding mode information HEIF, the resolution information 1080p, and the frame rate information of 30fps, and decoding time consumption of the test picture for the format.

According to an exemplary embodiment of the present disclosure, the generated decoding test result information and cover picture request information may be transmitted to the server according to a predetermined protocol through the communication unit of the terminal device at step S210. For example, the terminal device may access a network (e.g., a 3G, 4G, 5G mobile communication network) through the communication unit, so that a video application running on the terminal device may transmit decoding test result information and cover picture request information to the server through a preset protocol such as HTTP protocol. In this way, after the server receives the decoding test result information from the plurality of terminal devices, the format of the video cover picture for the terminal device can be determined according to the decoding test performance of the terminal devices of the same model for the picture of the predetermined format.

According to an exemplary embodiment of the present disclosure, before performing the decoding test (S210), the terminal device may transmit a decoding test request including model information of the terminal device to the server and receive decoding test configuration information as a response from the server. And the terminal equipment performs decoding operation on the test picture to obtain decoding test result information in response to the decoding test configuration information indicating that the decoding test is performed, and directly requests the server to acquire the video cover picture without performing the decoding operation on the test picture in response to the decoding test configuration information indicating that the decoding test is not performed. In this way, if it is determined at the server side that enough decoding test result information has been received from the terminal device of the model in the previous process, the performance of the terminal device of the model is known and the format of the video cover picture available for the terminal device is determined, the terminal device can be notified to skip the step of the test, thereby avoiding repeated execution of the test each time the video application is opened.

According to an exemplary embodiment of the present disclosure, if the decoding test configuration information indicates that the decoding test needs to be performed, the decoding test configuration information may further include an address for downloading the test picture, so that the terminal device may acquire the picture for performing the test according to the address.

According to an exemplary embodiment of the present disclosure, the received information about the video cover picture may include a download address indicating a video cover picture having a predetermined format (e.g., a Uniform Resource Locator (URL) for downloading the video cover picture) such that, after receiving the download address of the video cover picture, the terminal device may download the encoded video cover picture from the download address, decode the encoded video cover picture and render the decoded video cover picture to a picture control for video at step S220. Here, the server determines a format of a video cover picture suitable for the terminal device based on decoding test result information transmitted by a plurality of terminal devices of the same model of the terminal device. For example, if it is determined from the test result information that the terminal device has poor decoding performance (for example, decoding takes more time than a threshold or the memory occupancy is too high) for the test picture with the resolution of 1080p and the frame rate of 30fps of the HEIF encoding, the server may send the address of the video cover picture in other formats. For example, the address of a WEBP-encoded or JPEG encoded video cover picture may be transmitted.

As described above, since the decoding test is performed on the test picture in the predetermined format, the server can determine the format of the cover picture suitable for the terminal device, so that the loading speed of the cover picture for loading the video can be increased, and a better experience is brought to the user.

A method of configuring a video cover picture of a terminal device performed by a server according to an exemplary embodiment of the present disclosure will be described below with reference to fig. 3.

According to an exemplary embodiment of the present disclosure, the server may be a server for providing a service related to video. For example, the server may be a server that provides services related to a short video application, a live application, a social application, a video conferencing application, an instant messaging application, or an online educational application. The server may acquire various information from the terminal device through communication interaction with an application installed in the terminal device.

As shown in fig. 3, in step S310, the server receives decoding test result information and cover picture request information for a test picture from a plurality of terminal devices of the same model of the terminal device. As shown in fig. 1, the server 200 may receive decoding test result information from a plurality of terminal apparatuses 100-1, 100-2, 100-3, … 100-n, wherein decoding test results of terminal apparatuses of the same signals among the plurality of terminal apparatuses 100-1, 100-2, 100-3, … 100-n may be obtained.

According to an exemplary embodiment of the present disclosure, decoding test identifications for various models of terminal devices may be stored in a server. Each time decoding test result information is received from a certain model of terminal device, the decoding test result information of the received model of terminal device may be counted, and if a predetermined number (e.g., 100) of decoding test result information have been collected, the decoding test identifier corresponding to the model of terminal device may be changed to indicate no decoding test.

According to an exemplary embodiment of the present disclosure, in response to determining that the identification indicates that a decoding test is performed, decoding test configuration information including information indicating that a decoding test is performed is transmitted to the terminal device; and in response to determining that the identification indicates that the decoding test is not performed, transmitting decoding test configuration information including information indicating that the decoding test is not performed to the terminal device. That is, when the number of times the decoding test has been performed for the same model of terminal device exceeds a predetermined value, the identification corresponding to the model of terminal device indicates that the decoding test is not performed, and when the number of times the decoding test has been performed for the same model of terminal device does not exceed the predetermined value, the identification corresponding to the model of terminal device indicates that the decoding test is performed.

According to an exemplary embodiment of the present disclosure, the test picture may include still pictures and/or moving pictures having at least one format downloaded from the server, each of the still pictures and/or moving pictures having a specific resolution, frame rate, and encoding scheme, and the decoding test result information may include model information of the terminal device, encoding scheme of the test picture, picture resolution, frame rate, and decoding time consumption.

Next, in step S320, the format of the video cover picture for the model terminal device is determined according to the decoding test result information of the plurality of terminal devices.

According to an exemplary embodiment of the present disclosure, an average decoding time consumption of the model terminal device for the test picture may be determined according to decoding test result information received from the plurality of terminals, and a format of a video cover picture for the model terminal device may be determined according to the average decoding time consumption for the test picture at step S320. That is, if decoding test result information is received from 100 terminal devices of the same model, an average time consumption of the 100 devices for a test picture may be calculated, and if the average time consumption is lower than a threshold value, a format in which the test picture may be used as a format of a video cover picture of the terminal device of the model is determined.

According to an exemplary embodiment of the present disclosure, the format of the test picture is determined to be the format of the video cover picture for the model of the terminal device in response to determining that the average decoding time consumption corresponding to the format of the test picture is less than a threshold, and the default format is determined to be the format of the video cover picture for the model of the terminal device in response to determining that the average decoding time consumption corresponding to the format of the test picture exceeds the threshold.

For example, if the test picture issued by the server is a HEIF encoded picture and the decoding test result information received from the terminal device indicates that the decoding time consumption of the terminal device for the HEIF encoded test picture is above a threshold, the server may determine that it is not suitable to apply the HEIF encoded cover picture on the terminal device. At this time, a cover picture such as a JPEG encoding format may be used as a default cover picture.

According to an exemplary embodiment of the present disclosure, if the test pictures issued by the server have a plurality of formats, the server may determine at least one format of the test pictures having average decoding time less than a threshold value, and determine the format of the test picture having the highest priority among the at least one format as the format of the video cover picture for the terminal device of the model. Here, the priority may be a preference order for pictures of different formats set according to a predetermined rule.
