Detailed Description
The present application will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
It can be understood that with the continuous development of communication technology, video call becomes an important tool for people to exchange information. A video call is a call from one terminal to another in which each participant hears and sees the other participant, thereby communicating with the other participant. A video call between users may have only two participants and is limited to the participants' own audio and video. Whereas a video call in an enterprise environment may be more than two participants and may be provided with a multimedia presentation. The multimedia presentation may include office files, video content other than the presenter, and still pictures.
At present, along with the increasing network speed and the increasing mobile phone performance, the requirement of people on high-definition video call is also increased day by day. However, in the video call process, due to the influence of the network signal strength, when the pixel of the device is high, the data volume transmitted in the video call process is large, so that the picture is blocked, the picture cannot be stably and smoothly normally performed, and the user experience is poor.
Based on the above defects, embodiments of the present application provide a method, an apparatus, a device, and a medium for processing a video call, in which a maximum resolution of a transmission image is calculated through a network transmission speed and a system parameter, so that call parameters can be correspondingly adjusted based on the maximum resolution to perform a call, so that a terminal device can perform a call stably and smoothly regardless of a change in a network environment, and user experience is improved to a great extent.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating a system architecture of a video call method according to an embodiment of the present disclosure. As shown in fig. 1, the system architecture includes: a transmitting device 10 and a receiving device 20.
Optionally, the sending device 10 may be any user device that has a data sending function and can perform a video call. The network technology on which the terminal equipment depends to realize the video call is not limited, and the terminal equipment can be a voice technology VoLTE based on an LTE network, a video technology ViLTE based on the LTE network, a voice technology ViWiFi based on a WiFi network, or a video technology ViWiFi based on the WiFi network.
The receiving device 20 is configured to perform voice and image signal interaction with the sending device in response to the video call request after receiving the video call request sent by the sending device, so as to perform a video call.
The transmitting device 10 or the receiving device 20 according to the embodiment of the present application may include a mobile terminal such as a mobile phone, a tablet computer, a notebook computer, a palm computer, a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a navigation device, a wearable device, a smart band, smart glasses, a smart wristwatch, a pedometer, and a fixed terminal such as a digital TV, a desktop computer, and the like. For example, the video call provided by the embodiment of the present application may occur between the wearable device and the wearable device, may also occur between the wearable device and the mobile phone, may also occur between the wearable device and the personal computer, may also occur between the mobile phone and the personal computer, and may also occur between the mobile phone and the mobile phone.
The sending device may actively send the video call request, or receive the video call request sent by other devices, to perform the video call service. The sending device may send the video call request through a video call entry of the operating system, or may send the video call request through an installed third-party application, which may be, for example, instant messaging software.
For convenience of understanding and explanation, the video call processing method, apparatus, device and medium provided by the embodiments of the present application are described in detail below with reference to fig. 2 to 6.
Fig. 2 is a schematic flowchart illustrating a video call processing method according to an embodiment of the present application, where the method may be executed by a sending device. As shown in fig. 2, the method includes:
s101, acquiring the network transmission speed of the video call and the system parameters of the system for operating the video call function.
Specifically, the sending device may obtain the network transmission speed and the system parameter for operating the video call function in the video call process by calling the system interface, or may obtain the network transmission speed and the system parameter for operating the video call function in the video call process by using a third-party tool library. The third-party tool library can be, for example, a speed measurement tool library and a system parameter tool library.
The corresponding network transmission speeds are different when the device is in the network environment of different positions. For example, when the device is in a 2G network environment, the corresponding network transmission speed may be 10Kb/s-20Kb/s; when the device is in a 3G network environment, the corresponding network transmission speed may be 120Kb/s-600Kb/s; when the device is in a 4G network environment, the corresponding network transmission speed may be 1.5Mb/s-10Mb/s.
The system parameter may be, for example, a bit depth during the video call and a number of frames played per second during the video call.
And S102, determining the maximum resolution of the video call based on the network transmission speed and the system parameters.
In this step, after the network transmission speed and the system parameters are obtained, the bit depth in the video call process and the number of frames played per second in the video call process can be obtained from the system parameters, and then the maximum resolution in the video call process is calculated by adopting a preset algorithm based on the bit depth, the number of frames played per second and the network transmission speed.
Specifically, the maximum resolution of the video call can be calculated by the following formula:
wherein p represents the maximum resolution of the video call; v represents the network transmission speed of the video call; b represents the bit depth in the video call process; n represents the number of frames played per second during the video call.
The resolution is the precision of the screen image, and is how many pixels can be displayed on the display. Since the dots, lines and planes on the screen are made up of pixels, the more pixels the display can display, the finer the picture. The image resolution refers to the number of pixels contained within a unit inch.
In a video image, the color information of each pixel is described by a binary number of bits, which is called bit depth. Each cell storing 1 pixel can typically store 8 bits of binary number (byte addressing). We refer to the binary number that each memory cell can store as depth. Color bit depth refers to the number of binary bits used to store each pixel, and the color bit depth of an image directly affects the number of colors it can support. If the color bit depth of the image is denoted by a, the number of colors that the transmitted image can support is 2a. The color bit depth of the transmitted image is typically divided into 1 bit, 4 bits, 8 bits, 16 bits and 24 bits. In a 1-bit transmission image, each pixel can only be black or white; if the color bit depth is 24 bits, the number of supported colors is 1667 thousands, which is usually called true color, and the display screen of a typical device has a bit depth of 8 bits, 10 bits at the high end, and less preferably 6 bits.
S103, adjusting the call parameters of the video call according to the maximum resolution of the video call, and carrying out the call according to the adjusted call parameters.
In this step, the call parameter may include, for example, a target transmission object and a target resolution corresponding to the target transmission object, or may include parameters such as a call mode. The target transmission object may be, for example, a whole transmission image, where the whole transmission image is a first target image, or may be a target image corresponding to a target object, where the target image corresponding to the target object is a second target image, and for example, when the target object is a human face, the corresponding second target image is a human face image; and when the target object is a character, the corresponding second target image is a character image.
After the maximum resolution of the video call is calculated by adopting a preset algorithm, the current network signal state can be determined according to the maximum resolution of the video call, and then the call parameters are adjusted based on the current network signal state, so that a processed image is formed according to the adjusted call parameters, and the processed image is sent to equipment at the opposite end of the video call service. The method for adjusting the call parameters may be, for example, adjusting the resolution of the video call correspondingly, or adjusting the call mode so that the call parameters in the video call process can be matched with the current network signal state.
It should be noted that the maximum resolution of the video call is the resolution transmitted at the current network transmission speed and in compliance with the transmitted picture definition standard.
The adjustment of the resolution of the video call can be realized by adjusting the compression ratio of the image. The higher the compression ratio of the image, the lower the resolution of the image; the lower the compression ratio of the image, the higher the resolution of the image.
According to the video call processing method provided by the embodiment of the application, the network transmission speed and the system parameters of the video call are obtained, the maximum resolution of the video call is calculated based on the network transmission speed and the system parameters of a system running the video call function, then the call parameters of the video call are adjusted according to the maximum resolution of the video call, and the call is carried out according to the adjusted call parameters. According to the technical scheme, the maximum resolution of the video call is obtained through calculation according to the network transmission speed and the system parameters, so that call parameters can be correspondingly adjusted to carry out the call based on the maximum resolution, the data volume uploaded in the video call process is reduced, the terminal equipment can stably and smoothly carry out the call no matter how the network environment changes, and the user experience is improved to a great extent.
Optionally, on the basis of the foregoing embodiment, as shown in fig. 3, the step S103 may include the following method steps:
s201, determining a second target image from the first target image by adopting an image recognition algorithm.
S202, calculating the current resolution of the first target image and the resolution corresponding to the second target image, wherein the resolution corresponding to the second target image is smaller than the current resolution.
S203, comparing the maximum resolution with the current resolution and the resolution corresponding to the second target image, and determining the current network signal state.
And S204, adjusting the call parameters of the video call according to the current network signal state, and carrying out the call according to the adjusted call parameters.
In this embodiment, in the video call process, the second target image may be determined from the first target image by calling a system interface or a third-party tool library and using an image recognition algorithm. For example, the first target image may be subjected to image preprocessing to obtain a preprocessed image, the preprocessed image is subjected to feature extraction to obtain target feature points, and then the second target image is determined according to the target feature points. The first target image is an image of the whole video window, and the second target image is an image corresponding to the target object.
After a second target image is determined from the first target image, calculating the current resolution of the first target image and the resolution corresponding to the second target image, wherein the current resolution of the first target image is greater than the resolution corresponding to the second target image, then comparing the maximum resolution with the current resolution and the resolution corresponding to the second target image, determining the current network signal state, adjusting the call parameters of the video call according to the current network signal state, and carrying out the call according to the adjusted call parameters.
When the maximum resolution P0 of the video call is greater than or equal to the current resolution P1 corresponding to the first target image, namely P0 is greater than or equal to P1, determining that the current network signal state is a first network state, wherein the first network state represents that the current network environment is good.
When the maximum resolution P0 of the video call is smaller than the current resolution P1 corresponding to the first target image and is greater than or equal to the resolution P2 corresponding to the second target image, namely P1> P0 is greater than or equal to P2, the current network signal state is determined to be a second network state, and the second network state represents that the current network environment is poor.
And when the maximum resolution P0 of the video call is smaller than the resolution P2 corresponding to the second target image, determining that the current network signal state is a third network state, wherein the third network state represents the worst current network environment.
If the current network signal state is determined to be the first network state, determining that a target transmission object of the video call is a first target image, determining that the current resolution corresponding to the first target image is the target resolution, adjusting the first target image according to the current resolution to form a processed image, and then sending the processed image to equipment at the opposite end of the video call service so as to perform call transmission with the equipment at the opposite end of the video call service. And if the current network signal state is determined to be the second network state, determining that a target transmission object of the video call is a second target image, determining the maximum resolution as the target resolution of the video call, adjusting the second target image with the maximum resolution to form a processed image, and then sending the processed image to equipment at the opposite end of the video call service so as to perform call transmission with the equipment at the opposite end of the video call service. And if the current network signal state is determined to be the third network state, adjusting the call mode from the video call mode to the voice call mode, and then carrying out the call in the voice call mode.
Exemplarily, a wearable device such as a smart watch is used as the sending device, a user of the smart watch is a child, an opposite-end device communicating with the smart watch is a mobile phone, and a user of the smart phone is a parent. When the smart watch and the smart phone carry out video call, the smart watch can acquire the network transmission speed of the video call and the system parameters of a system for running the video call, wherein the system parameters comprise bit depth and the number of frames played per second, and then the maximum resolution of the video call is calculated by adopting a preset algorithm based on the bit depth, the number of frames played per second and the network transmission speed. The intelligent watch can identify a first target image collected by a camera according to a preset video, determine a second target image from the first target image by adopting an image identification algorithm, and calculate to obtain the current resolution of the first target image and the resolution corresponding to the second target image.
When the maximum resolution of the video call is greater than or equal to the current resolution, determining that the current network signal state is a first network state, determining that a target transmission object of the video call is a first target image, determining the current resolution corresponding to the first target image as the target resolution, adjusting the first target image according to the current resolution to obtain a processed image, and sending the processed image to the smart phone; when the maximum resolution of the video call is smaller than the current resolution corresponding to the first target image and larger than or equal to the resolution corresponding to the second target image, determining that the current network signal state is the second network state, determining that a target transmission object of the video call is the second target image, determining the maximum resolution of the video call as the target resolution, adjusting the second target image according to the maximum resolution to obtain a processed image, and sending the processed image to the smart phone; when the maximum resolution of the video call is smaller than the resolution corresponding to the second target image, the current network signal state is determined to be the third network state, the call mode is adjusted from the video call mode to the voice call mode, and then the call is carried out with the smart phone in the voice call mode.
In the embodiment, the current resolution of the first target image and the resolution corresponding to the second target image are calculated, the maximum resolution is compared with the current resolution and the resolution corresponding to the second target image, the current network signal state is determined, and the call parameters are intelligently adjusted according to the current network signal state to carry out call, so that the data volume uploaded in the video call process is reduced, the problem of blocking is solved, and the user experience is improved.
