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.
With the rapid development of science and technology and the continuous improvement of living standard of people, live broadcast is more and more popular in recent years, and the live broadcast can create strong sense of scene, so that audiences can form a deep impression when watching the live broadcast. In the related art, many users directly use terminals such as mobile phones and tablet computers to perform live broadcasting.
The technical scheme provided by the embodiment of the disclosure relates to three parties as shown in fig. 1 a: the mobile terminal includes a first terminal 111, a server 100, and a second terminal 102, where the first terminal 111 and the second terminal 102 may be a mobile phone, a tablet computer, a smart wearable device, a television, or a computer, and other devices capable of interacting with the server 100, and this is not limited in the embodiments of the present disclosure. The server 101 may be a device that provides a computing service and is provided and used by a live operator, or may be a device that provides a computing service and is provided and used by a network operator. The server 100 establishes data connections with the first terminal 111 and the second terminal 102 through a wireless communication network or a wired communication network, respectively. In the live broadcast, the anchor 103 may select to capture a live video using the first terminal 111 and upload the captured live video to the server 100, and the second terminal 102 may download the live video uploaded by the anchor from the server 100 and display the live video on the second terminal 102, so that the viewer can watch the live video.
In the related art, the terminal may display a video photographed by the terminal on a display screen of the terminal when the video is photographed by the front camera, in order to keep a user's own image seen through the display screen consistent with the user's own image seen in a mirror, wherein the video displayed on the display screen of the terminal may be a video photographed by the front camera and horizontally mirrored. And if the anchor takes a video through a front camera device of the terminal, and the taken video is used for live broadcasting. The live video uploaded by the terminal can also be a video shot by a front camera and subjected to horizontal mirror image transformation. For example, fig. 1b is a schematic diagram of a live broadcast scene provided by an embodiment of the present disclosure, as shown in fig. 1b, when the anchor 103 uses the first terminal 101 to perform live broadcast, live broadcast software running on the first terminal 101 is in an anchor live broadcast mode, the front camera 111 on the first terminal 101 may shoot the anchor 103, and display the shot video after performing horizontal mirror transformation as a video collected by the first terminal 101 in a live broadcast interface of the live broadcast software, where an own image 121 seen by the anchor 103 in the interface of the live broadcast software is consistent with an own image seen by the anchor 103 in a mirror. Meanwhile, the first terminal 101 uploads the video collected by the first terminal to the server 100, the second terminal 102 downloads the video from the server, and when the live broadcast software running on the second terminal 102 is in a viewer watching mode, the video is played in an interface of the live broadcast software running on the second terminal 102, and at this time, the anchor image 112 seen by the viewer is consistent with the self image 121 seen by the anchor 103.
However, when the video collected by the first terminal includes content that can be correctly understood by the horizontal mirror transformation, if the video collected by the first terminal is directly displayed on the second terminal, difficulty in understanding the content in the live video by the audience is increased, and user experience is damaged. Illustratively, fig. 1c is a schematic diagram of a live scene provided by an embodiment of the present disclosure, as shown in fig. 1c, when the anchor 103 uses the first terminal 101 for live broadcasting, a video may be captured by the front camera 111 on the first terminal 101, where the captured video includes a live frame 113, and the live frame 113 includes characters, numbers, symbols, or the like. After horizontal mirror image transformation is carried out on a shot video by the first terminal 101 of the mobile phone, the shot video can be displayed in a live broadcast interface of live broadcast software running on the first terminal 101, wherein the displayed video comprises a live broadcast display picture 131, and the live broadcast display picture 131 comprises characters, numbers or symbols and the like after the horizontal mirror image transformation because the live broadcast display picture 131 is a live broadcast picture 113 after the horizontal mirror image transformation. Meanwhile, the first terminal 101 uploads the video including the live presentation screen 131 as a live video to the server 100, and the second terminal 102 downloads the live video from the server. When the live broadcast software running on the second terminal 102 is in the viewer viewing mode, the live broadcast video can be played in the interface of the live broadcast software, and the live broadcast video viewed by the viewer includes the live display picture 131. At this time, the live display screen 131 includes characters, numbers, symbols, or the like after horizontal mirroring conversion, and if the content is not horizontally mirrored again, it is difficult for the viewer to understand the content in the live video, thereby impairing the user experience.
In order to solve the above problem, in the technical solution provided in the embodiment of the present disclosure, at least one picture in a live video is acquired, and when it is determined that display content of the at least one picture satisfies a preset condition, a mirror image conversion video for display is acquired. Therefore, when the live video comprises the content which can be correctly understood through the horizontal mirror image transformation, the mirror image transformation video for display is obtained, so that when the mirror image transformation video is displayed to audiences, the audiences can easily understand the content, and the user experience is improved.
The embodiment of the disclosure provides a live broadcast method, which can be applied to a first terminal and also can be applied to a second terminal or a server. As shown in fig. 2, the light intensity information processing method includes the following steps 201 to 202:
in step 201, at least one picture in a live video is acquired.
Illustratively, when the method is applied to the first terminal, the live video may be a video acquired by the first terminal during live broadcasting; when the method is applied to the server, the live video can be a video uploaded to the server by the first terminal during live broadcasting; when the method is applied to the second terminal, the live video can be a video downloaded from the server by the second terminal. At least one picture in the live video is acquired, and the pictures with a preset number of frames can be selected from the live video according to a specified time interval, wherein the preset number is greater than or equal to 1.
In step 202, when it is determined that the display content of at least one picture meets a preset condition, a mirror-converted video for display is acquired.
The mirror image conversion video is a video obtained by performing horizontal mirror image conversion on a live video.
For example, it is determined that the display content of the at least one screen meets the preset condition, the display content of the at least one screen may include content that can be correctly understood by the horizontal mirror transformation, or the proportion of the screen that includes the content that can be correctly understood by the horizontal mirror transformation in the at least one screen is greater than a certain threshold. The content that can be correctly understood by the horizontal mirror transformation may include characters, numbers, symbols, or the like, and the embodiments of the present disclosure are not limited herein.
According to the technical scheme, at least one picture in a live video is obtained, and when the display content of the at least one picture meets the preset condition, the mirror image conversion video for display is obtained. According to the technical scheme, when the content which can be correctly understood by a horizontal mirror transformation party is included in the live video, the live video is subjected to horizontal mirror transformation to obtain the mirror transformation video, so that when the mirror transformation video is displayed to audiences, the audiences can easily understand the content, and the user experience is improved.
The embodiment of the disclosure provides a live broadcasting method, an execution main body implementing the method can be a first terminal, a second terminal or a server, wherein the first terminal can be a terminal for acquiring videos during live broadcasting, the second terminal can be a terminal for playing videos during live broadcasting, and the terminal can be a mobile terminal, such as a mobile phone or a tablet personal computer, and can also be a fixed terminal, such as a computer or a television. According to different implementation main bodies of the method, three sets of live broadcast implementation methods are arranged, and the method comprises the following steps:
first terminal side
Fig. 3a is a flowchart illustrating a live method according to an exemplary embodiment, and as shown in fig. 3a, the live method is used in a first terminal and includes the following steps 301 to 302:
in step 301, a first terminal obtains at least one picture in a live video.
Illustratively, the live video may be a video captured by the first terminal while live. For example, a live Application (APP) may be installed in the first terminal, and the first terminal may detect a live broadcast start instruction input by a user through an operation page of the live APP, and capture a live broadcast video according to the live broadcast start instruction. After the live broadcast video is acquired, the first terminal can select the pictures with the preset number of frames from the live broadcast video according to the specified time interval, and the pictures with the preset number of frames are used as at least one picture in the live broadcast video, wherein the specified time interval and the preset number can be preset in the first terminal, and can also be acquired by detecting click actions or sliding actions of a user in an operation page of a live broadcast APP.
In step 302, when it is determined that the display content of at least one picture meets a preset condition, a mirror image transformation video for display is acquired by the first terminal.
The mirror image conversion video is a video obtained by performing horizontal mirror image conversion on a live video.
For example, the first terminal may detect whether each of the at least one picture includes content that can be correctly understood by the horizontal mirroring, and may determine that the content displayed in the at least one picture satisfies the preset condition when it is determined that each of the at least one picture includes content that can be correctly understood by the horizontal mirroring or it is determined that a proportion of the at least one picture including content that can be correctly understood by the horizontal mirroring is higher in the at least one picture. The first terminal may also select a part of the pictures from the at least one picture according to a specified sampling ratio, and detect one by one whether the selected part of the pictures includes content that can be correctly understood by the horizontal mirror image transformation, and when it is determined that each of the selected part of the pictures includes content that can be correctly understood by the horizontal mirror image transformation, or it is determined that a proportion of the pictures including the content that can be correctly understood by the horizontal mirror image transformation in the selected part of the pictures is higher, it may be determined that the display content of the at least one picture satisfies a preset condition. It should be noted that, the content that can be correctly understood by the horizontal mirror transformation may include characters, numbers, symbols, or the like, and the embodiment of the disclosure is not limited herein.
For example, the mirror image conversion video for displaying may be obtained by performing horizontal mirror image conversion on a live video to obtain the mirror image conversion video, or may be obtained by obtaining a video identifier for indicating the live video, and determining, in a video library, the mirror image conversion video corresponding to the video identifier according to the video identifier. The horizontal mirror transformation may be to transform a picture of each frame in the live video with a vertical central axis of the picture as a center to a pixel in the picture. For example, when it is determined that the display content of at least one frame meets the preset condition, the width w and the length h of the frame in the live video may be obtained, and the position of the pixel in the frame of each frame in the live video may be transformed according to the following formula to obtain the mirror-transformed video:
x＝w-x0-1
y＝y0
wherein (x)0,y0) For the coordinates of the pixels in the picture of each frame in the live video before transformation, (x, y) for the coordinates of the pixels in the picture of each frame in the live video after transformation. The mirrored video may be for presentation on the first terminal, or may be transmitted by the first terminal to the server, downloaded from the server to the second terminal and for presentation on the second terminal.
Fig. 3b is a schematic diagram of a live scene provided by an embodiment of the present disclosure, and as shown in fig. 3b, when the method is applied to the first terminal 101, the first terminal 101 captures a video through the front camera 111, where the captured video includes a live frame 113, and the live frame 113 includes characters, numbers, or symbols. The first mobile phone terminal 101 may be used as a live video after performing horizontal mirroring on the captured video, and at this time, the live video includes a live frame 113 subjected to horizontal mirroring, so that the live frame 113 subjected to horizontal mirroring includes characters, numbers, symbols, and the like subjected to horizontal mirroring, and the above contents may be difficult for viewers to understand if being directly displayed. When the first terminal 101 acquires at least one picture in the live video and determines that the display content of the at least one picture meets a preset condition, the first terminal 101 may acquire a mirror-image-converted video for display, and upload the mirror-image-converted video to the server 100, where the mirror-image-converted video includes a mirror-image-converted picture 141, and the mirror-image-converted picture 141 includes characters, numbers, symbols, or the like that are horizontally mirrored again. The second terminal 102 downloads the mirror-converted video from the server. When the live broadcasting software running on the second terminal 102 is in the audience watching mode, the mirror image conversion video can be displayed in the interface of the live broadcasting software, and because characters, numbers or symbols in the mirror image conversion picture 141 are horizontally mirror-converted again, the audience can easily understand the contents.
According to the technical scheme provided by the embodiment of the disclosure, at least one picture in a live video is acquired by a first terminal, and when it is determined that the display content of the at least one picture meets a preset condition, a mirror image conversion video for display is acquired by the first terminal. According to the technical scheme, when the content which can be correctly understood by a horizontal mirror image transformation party is included in the live video, the first terminal performs horizontal mirror image transformation on the live video to obtain the mirror image transformation video, so that when the mirror image transformation video is displayed to audiences, the audiences can easily understand the content, and the user experience is improved.
In one embodiment, as shown in fig. 3c, in step 302, when it is determined that the display content of at least one screen satisfies the preset condition, acquiring, by the first terminal, a mirror-transformed video for display may be implemented by step 3021:
in step 3021, when it is determined that the number of text pictures in the at least one picture is greater than or equal to the first picture number threshold, obtaining, by the first terminal, a mirror-converted video.
Wherein, the text picture is a picture with display contents including texts.
For example, the first terminal may perform text recognition on the display content of each of the at least one picture one by one, and divide the at least one picture into a text picture group and a non-text picture group according to the recognition result, where the picture in the text picture group may be a picture whose display content includes text according to the recognition result; the pictures in the non-text picture group can be pictures which are determined to be the pictures with the display contents not including the text according to the identification result. The characters may be chinese characters, english letters, german letters, japanese characters, french letters, portuguese letters, spanish letters, numbers, symbols, and other characters or parts of characters, and the embodiments of the disclosure are not limited herein. When the number of pictures in the text picture group is greater than or equal to the first picture number threshold, the mirror image transformation video can be acquired. The first picture quantity threshold may be set in the first terminal in advance, or may be obtained by detecting a click action or a slide action of a user in an operation page of a live APP.
In the technical scheme provided by the embodiment of the disclosure, when the number of character pictures in at least one picture acquired from a live video is determined to be excessive, a mirror image transformation video for display is acquired by a first terminal. Because the text image comprises the text which is difficult to understand and subjected to horizontal mirror image conversion, the difficulty of understanding the content of the live video containing excessive text images by the audience is increased when the live video is directly displayed. In the mirror image transformation video, the characters in the character picture can be normally understood after horizontal mirror image transformation, so that when the mirror image transformation video is displayed, audiences can easily understand the contents in the character picture, and the user experience is improved.
In one embodiment, as shown in fig. 3d, in step 302, when it is determined that the display content of at least one screen satisfies the preset condition, acquiring, by the first terminal, a mirror-transformed video for display may be implemented by step 3022:
in step 3022, when it is determined that the number of multi-object pictures in the at least one picture is greater than or equal to the second picture number threshold, acquiring, by the first terminal, a mirror-converted video.
The multi-object picture is a picture with the number of objects in the display content being greater than or equal to the threshold value of the number of object pictures.
For example, the first terminal may perform object recognition on the display content of each of the at least one screen one by one, and divide the at least one screen into a plurality of screen groups according to the recognition result, where each screen group includes the corresponding object number identifier and the screen whose display content includes the number of objects indicated by the object number identifier, for example, the screen in the first screen group may be a screen whose display content includes a single object according to the recognition result, the screen in the second screen group may be a screen whose display content includes two objects according to the recognition result, the screen in the third screen group may be a screen whose display content includes three objects according to the recognition result, and so on. Wherein the object may be a human body, an animal, a plant, a vehicle or furniture, and the embodiments of the present disclosure are not limited thereto. And then the first terminal acquires an object quantity threshold value and determines a picture group to be counted in the plurality of picture groups according to the object quantity threshold value, wherein the picture group to be counted is the picture group of which the quantity indicated by the object quantity identifier in the plurality of picture groups is greater than or equal to the object quantity threshold value. When the number of pictures in the counted picture group is greater than or equal to the second picture threshold value, in order to facilitate a user to understand the relative position between different objects or the relative movement between different objects in the live video, the mirror-transformed video may be acquired. The object quantity threshold and the second picture quantity threshold may be set in the first terminal in advance, or may be obtained by detecting a click action or a slide action of the user in an operation page of the live APP.
In the technical scheme provided by the embodiment of the disclosure, when the number of multiple object pictures in at least one picture acquired from a live video is determined to be too large, the first terminal acquires a mirror image conversion video for display, and because the multiple object pictures are directly displayed, the displayed pictures are subjected to horizontal mirror image conversion, the position relation among the multiple objects cannot be correctly reflected, and the scheme can ensure that when the proportion of the pictures containing the multiple objects in the live video is higher, the first terminal acquires the mirror image conversion video obtained by performing horizontal mirror image conversion on the live video, so that the position relation among the multiple objects in the video can be correctly reflected when the mirror image conversion video is displayed, thereby improving user experience.
In one embodiment, as shown in fig. 3e, the live broadcasting method provided by the embodiment of the present disclosure further includes the following steps 303:
in step 303, the first terminal obtains a mirroring transformation instruction.
Illustratively, a live broadcast APP can be operated on a first terminal, when the first terminal is used for live broadcast, a mirror image transformation option can be displayed in an operation interface of the live broadcast APP, meanwhile, a click position of a user on an operation page can be monitored in real time, and if the click position of the user is matched with the mirror image transformation option, the first terminal confirms that a mirror image transformation instruction input by the user is received. Or, a preset operation mode corresponding to the mirror image transformation instruction may be set on the first terminal during initialization, where the preset operation mode may be a preset number of times of clicking a screen within a preset time period, or a preset number of times of clicking a physical key within a preset time period, and the like. When the first terminal is used for live broadcasting, the number of clicks on the operation page within a preset time period of a user can be monitored in real time, and if the number of clicks of the user is the same as the preset number, the first terminal confirms that a mirror image conversion instruction input by the user is received.
In step 302, when it is determined that the display content of at least one screen satisfies the preset condition, acquiring, by the first terminal, a mirror-image-converted video for display, which may be implemented by step 3023:
in step 3023, when it is determined that the presentation content of the at least one screen satisfies the preset condition, acquiring, by the first terminal, a mirror-converted video in response to the mirror-conversion instruction.
According to the technical scheme, the first terminal acquires the mirror image transformation instruction and determines that the display content of at least one picture meets the preset condition, the first terminal responds to the mirror image transformation instruction to acquire the mirror image transformation video, so that a user can control whether the video used for display is the video subjected to horizontal mirror image transformation, the space selected by the user during live broadcasting is increased, and the user experience is improved.
In one embodiment, as shown in fig. 3f, in step 3023, when it is determined that the display content of at least one screen satisfies the preset condition, acquiring a mirror-converted video by the first terminal in response to the mirror-conversion instruction may be implemented by step 30231:
in step 30231, when it is determined that the display content of the at least one screen satisfies the preset condition and the live video is the video captured by the front camera of the terminal, the first terminal obtains the mirror-converted video in response to the obtaining of the mirror-converted instruction.
Illustratively, a live broadcast APP can run on a first terminal, when the first terminal is used for live broadcast, a front camera option and a rear camera option can be selected in an operation page of the live broadcast APP, a click position of a user on the operation page is monitored in real time, and if the click position of the user is matched with a front camera, the first terminal acquires a video through the front camera; and if the click position of the user is matched with the rear camera device, the first terminal acquires a video through the rear camera device. When first terminal passes through back camera device and gathers the video, can be directly with the video of gathering through back camera device as live broadcast video, because above-mentioned live broadcast video does not change by horizontal mirror image, consequently need not first terminal and confirm whether it satisfies the condition of predetermineeing when live, can directly upload to the server. When first terminal was through preceding camera device collection video, can show on the display screen after carrying out horizontal mirror image transform with the video of camera device collection before through simultaneously to regard as live video with the video after the horizontal mirror image transform, and upload this live video, so that show this live video. When the live video is the video acquired by the front camera device of the terminal, the content which is difficult to understand due to horizontal mirror image transformation may exist in the live video, so that when the live video is determined to be the video acquired by the front camera device of the terminal and the display content of at least one picture meets the preset condition, the mirror image transformation video is acquired in response to the acquired mirror image transformation instruction. The mirror image transformation video can enable a user to easily understand the content of the mirror image transformation video during display.
According to the technical scheme, when the display content of at least one picture meets the preset condition and the live video is determined to be the video collected through the front camera device of the terminal, the first terminal responds to the mirror image conversion acquisition instruction to acquire the mirror image conversion video, and the scheme can ensure that only the video collected through the front camera device of the terminal is subjected to horizontal mirror image conversion to acquire the mirror image conversion video, so that resources consumed during live broadcasting are reduced, and user experience is improved.

in step 401, a server obtains at least one picture in a live video.
For example, the live video may be a video uploaded to the server by the first terminal during live broadcasting. For example, when the server receives a main broadcast video uploaded by the first terminal, a preset number of frames of pictures may be selected from the live broadcast video according to a specified time interval, and the preset number of frames of pictures may be used as at least one picture in the live broadcast video, where the specified time interval and the preset number may be set in advance on the server, or may be obtained according to a specified time interval command and a preset number command sent by the first terminal or the second terminal, where the first terminal or the second terminal may obtain the specified time interval and the preset number input by the user by detecting a click action or a sliding action of the user in an operation page of the live broadcast APP, and send a preset number command indicating the preset number and a specified time interval command indicating the specified time interval to the server.
In step 402, when it is determined that the display content of at least one picture meets a preset condition, a mirror-converted video for display is acquired by a server.
For example, the server may detect whether each of the at least one picture includes content that can be correctly understood by the horizontal mirroring, and when it is determined that each of the at least one picture includes content that can be correctly understood by the horizontal mirroring, or it is determined that a proportion of the at least one picture including content that can be correctly understood by the horizontal mirroring is higher, it may be determined that the display content of the at least one picture satisfies a preset condition. The server may also select a part of the pictures from the at least one picture according to a specified sampling ratio, and detect one by one whether the selected part of the pictures includes content that can be correctly understood by the horizontal mirror transformation party, and when it is determined that each of the selected part of the pictures includes content that can be correctly understood by the horizontal mirror transformation party, or it is determined that a proportion of the pictures including the content that can be correctly understood by the horizontal mirror transformation party in the selected part of the pictures is higher, it may be determined that the display content of the at least one picture satisfies a preset condition. It should be noted that, the content that can be correctly understood by the horizontal mirror transformation may include characters, numbers, symbols, or the like, and the embodiment of the disclosure is not limited herein.
According to the technical scheme, at least one picture in live videos uploaded to a server by a first terminal is obtained, and when it is determined that display contents of the at least one picture meet preset conditions, a mirror image conversion video for display is obtained by the server. According to the technical scheme, when the content which can be correctly understood by a horizontal mirror transformation party is included in the live video, the server performs horizontal mirror transformation on the live video to obtain the mirror transformation video, so that when the mirror transformation video is displayed to audiences, the audiences can easily understand the content, and the user experience is improved.
In one embodiment, as shown in fig. 4b, in step 402, when it is determined that the display content of at least one screen satisfies a preset condition, acquiring, by a server, a mirror-transformed video for display may be implemented by step 4021:

Wherein, the text picture is a picture with display contents including texts.
For example, the server may perform character recognition on the display content of each of the at least one picture one by one, and divide the at least one picture into a character picture group and a non-character picture group according to the recognition result, where the picture in the character picture group may be a picture whose display content includes characters according to the recognition result; the pictures in the non-text picture group can be pictures which are determined to be the pictures with the display contents not including the text according to the identification result. The characters may be chinese characters, english letters, german letters, japanese characters, french letters, portuguese letters, spanish letters, numbers, symbols, and other characters or parts of characters, and the embodiments of the disclosure are not limited herein. When the number of pictures in the text picture group is greater than or equal to the first picture number threshold, the mirror image transformation video can be acquired. The first picture quantity threshold value may be set in the server in advance, or may be obtained according to a first picture quantity threshold value command sent by the first terminal or the second terminal, where the first terminal or the second terminal may obtain the first picture quantity threshold value input by the user by detecting a click action or a sliding action of the user in an operation page of the live APP, and send a first picture quantity threshold value command indicating the first picture quantity threshold value to the server.
According to the technical scheme, when the number of character pictures in at least one picture acquired from a live video is determined to be excessive, a mirror image transformation video for display is acquired by a server. Because the text image comprises the text which is difficult to understand and subjected to horizontal mirror image conversion, the difficulty of understanding the content of the live video containing excessive text images by the audience is increased when the live video is directly displayed. In the mirror image transformation video, the characters in the character picture can be normally understood after horizontal mirror image transformation, so that when the mirror image transformation video is displayed, audiences can easily understand the contents in the character picture, and the user experience is improved.

When the number of pictures in the counted picture group is greater than or equal to the second picture threshold value, in order to facilitate a user to understand the relative position between different objects or the relative movement between different objects in the live video, the mirror-transformed video may be acquired. The object quantity threshold and the second picture quantity threshold may be set in the second terminal in advance, or the object quantity threshold input by the user may be obtained by detecting a click action or a slide action in an operation page of a live APP running on the second terminal by the user.
In the technical scheme provided by the embodiment of the disclosure, when the number of multiple object pictures in at least one picture acquired from a live video is determined to be too large, the mirror image conversion video for display is acquired by the second terminal, and because the multiple object pictures are directly displayed, the displayed pictures are subjected to horizontal mirror image conversion, the position relation among the multiple objects cannot be correctly reflected, and the scheme can ensure that when the proportion of the pictures containing the multiple objects in the live video is higher, the mirror image conversion video obtained by performing horizontal mirror image conversion on the live video is acquired, so that when the mirror image conversion video is displayed, the position relation among the multiple objects in the video can be correctly reflected, and thus, the user experience is improved.
In one embodiment, as shown in fig. 5d, the live broadcasting method provided by the embodiment of the present disclosure further includes the following steps 503:
