Fig. 1A is a schematic flowchart of a method for controlling live video provided in an embodiment of the present application, and as shown in fig. 1A, the method includes, but is not limited to, the following steps:

s100, acquiring video live broadcast data;

specifically, the terminal on the viewer side may acquire the live video data through the network. Fig. 1B is a schematic diagram of an architecture of a live video broadcast provided by the embodiment of the present application, and the architecture includes one or more terminals 101 on a viewer side, a server 102, and a live device 103 on a main broadcast side or main broadcast side. After acquiring the live video data, the live video equipment 103 sends the live video data to the server 102 through the network 103, and then the server 102 forwards the live video data to the terminal 101, so that the terminal 101 can acquire the live video data.

Step S102, playing and displaying video content corresponding to the video live broadcast data in a first playing and displaying area of a display interface;

specifically, the first playing display area in the embodiment of the present application may be a full screen area, that is, the entire display interface; as shown in fig. 2, in an interface display diagram of live video provided in this embodiment of the present application, the first playing display area 201 may also be a non-full screen area, and this application is not limited. And continuously playing the acquired live video data in the first playing display area.

Step S104, receiving a first control instruction aiming at the video content; the first control instruction is used for indicating on-demand review of the video content;

specifically, in the process of watching the live video, if there is a review requirement for the content that has just been watched, the user may input a first control instruction to instruct that the video content is to be reviewed on demand. The terminal receives a first control instruction for the video content.

The input of the first control instruction may be triggered according to a first operation input by a user, where the first operation may be an operation of clicking a virtual button or a control, an operation of pressing a display area, a preset sliding operation, and the like, and the application is not limited.

And S106, dividing a second playing display area and a third playing display area on the display interface according to the first control instruction.

Specifically, as shown in fig. 2, in response to the first control instruction, the terminal divides a second play display area 202 and a third play display area 203 into display interfaces, which are equivalent to split display. The second playing and displaying area 202 is used for continuously playing and displaying the video content corresponding to the obtained video live broadcast data; the third display area 203 is used for playing back the video content before the first control instruction is received. The user can control the playing of the video content in the third playing display area 203 to realize review.

In the following, the embodiments of the present application will be described by taking a description of a PPT document on a host side as an example: the video content of the embodiment of the present application may be a PPT video file.

The PPT video file in the embodiment of the present application may contain an image corresponding to each slide in the PPT document and a playing time stamp of each slide. Specifically, after video content uploaded by live broadcast equipment on the anchor side is acquired, the server may acquire an image corresponding to each slide in the PPT document and a playing time stamp of each slide by analyzing the video content, and then generate a PPT video file. The PPT video file also includes audio data for the anchor presentation.

In a possible implementation manner, a server may obtain a PPT document uploaded by a live device on a anchor side in advance, then control a command for playing the PPT document according to the received anchor, and then generate a corresponding slide image or picture for each slide in the PPT document; and acquiring the playing time stamp of each slide in the playing process, and establishing a mapping relation between the generated image and the time stamp so as to generate the PPT video file. The mapping relationship facilitates the subsequent operation of adjusting the playing progress.

In a possible implementation manner, the server may obtain a PPT document uploaded by live broadcast equipment on the anchor side in advance, analyze a change degree of video live broadcast content through an intelligent image analysis algorithm, extract an image frame of which the change degree exceeds a certain threshold to form a slide, and record a change time as a play time stamp in a playing process of the slide. And then the server acquires the playing time stamp of each slide in the playing process, and establishes a mapping relation between the generated image and the time stamp, thereby generating the PPT video file. The mapping relationship facilitates the subsequent operation of adjusting the playing progress.

In the embodiment of the present application, the image corresponding to the slide show is specifically an image containing part or all of the content in the slide show. The presentation time stamp for each slide image includes: the starting time point and the duration of each slide image. For example, as shown in table 1, the PPT document includes 10 slides, and for each slide, a corresponding slide image is generated, namely image 1, image 2, and image 10. Taking image 1 as an example, the starting time point of the image starting playing is 0s, and the duration of the image playing is 2min20 s.

TABLE 1 mapping relationship between images and timestamps

Slide show	Numbering	Starting point in time	Duration of continuous play
				Image 1	1	0s	2min20s
Image 2	2	2min20s	2min25s
				Image 3	3	4min45s	2min35s
......	......	......	......
				Image 10	10	45min20s	4min00s

In a possible implementation manner, when the server sends the video live broadcast data to the terminal on the viewer side, the server can simultaneously carry the image corresponding to each slide in the PPT document and the playing time stamp of each slide to send to the terminal. Or when the user inputs the first control instruction, the image corresponding to each slide in the PPT document and the playing time stamp of each slide are sent to the terminal.

With reference to fig. 3A, which is a schematic flow chart of a control method for video playback provided in the embodiment of the present application, how to play and display video content in a third playing display area after a second playing display area and the third playing display area are divided from the display interface is described:

step S300, after a second playing display area and a third playing display area are divided on the display interface, displaying a first slide image in the third playing display area; the first slide image is a slide image which is correspondingly played by the video content at the moment of receiving the first control instruction;

in this embodiment of the application, as shown in fig. 3B, a touch button may be displayed in a third display area of the terminal, and specifically, the touch button may include: a play button and a page turning button; wherein, the play button is used for controlling the play of the video layer (the play can include play start and play pause); and the page turning button is used for controlling the turning of the slide images. In an embodiment of the present application, the page turning buttons may include a page up button, a page down button, a fast page up button, and a fast page down button. Wherein, the page up button is used to flip the currently displayed slide image (i.e., the first slide image) to the upper 1 slide image; a page down button for flipping the currently displayed slide image to the next 1 slide image; a fast page-up button for flipping the currently displayed slide image to the top N slide images, where N is a positive integer greater than 1; a fast page down button for flipping the currently displayed slide image to the next N slide images, where N is a positive integer greater than 1. It should be noted that the display of the play button and the page turning button provided in the embodiment of the present application is only an example and should not be limited, for example, the page turning button may be displayed on the left and right sides of the terminal.

In this embodiment of the present application, in a case that a slide includes an animation playback element, a slide image corresponding to a current playback time may be a sub-image corresponding to a certain animation playback element, or may be an image in which all animation playback elements complete animation effect display.

In some implementations, if the PPT document contains a first slide, the first slide contains animation playback elements, which may include an entry effect or an exit effect for text, pictures, charts, video, and the like. At this time, the terminal may obtain a playing sequence of animation playing elements included in the first slide, and generate the first dynamic image of the first slide according to the playing sequence of the animation playing elements, and then, after the terminal receives a playing control instruction initiated by a user, if a slide image corresponding to a current playing time includes animation playing elements, then the slide image corresponding to the current playing time is displayed, the playing dynamic image is displayed according to the playing sequence of the included animation playing elements, that is, the PPT video file in the playing state is covered by the dynamic image of the slide. The dynamic images of the slides can represent the richness of the slide demonstration effect, so that the user can better know the PPT document content, and the use experience of the user can be improved.

In some implementations, the implementation process of the terminal generating the dynamic image according to the playing sequence of the animation playing elements may include: the terminal obtains the starting playing time and the ending playing time of each animation playing element in the PPT video file, and then the PPT video file can be cut according to the starting playing time and the ending playing time of each animation playing element to obtain the animation playing video corresponding to each animation playing element. Taking the first animation playing video corresponding to the first animation playing element as an example, in this case, the terminal decodes the first animation playing video to obtain a video frame sequence corresponding to the first animation playing video, and then extracts a preset number of video frames in the video frame sequence according to a preset extraction rule, so as to generate a dynamic image corresponding to the first animation playing element according to the extracted video frames. Here, the preset decimation rule may include decimation at a fixed video frame interval, for example, decimation by one video frame every two frames, decimation by one video frame every three frames, and so on. In this implementation, it can be ensured that the generated dynamic image completely contains the characteristics of the animation playing element.

In this embodiment of the application, the terminal may determine whether the video frame of the PPT video file includes an animation playing element by detecting whether the video frame of the PPT video file changes, and acquire the animation playing video corresponding to the animation playing element when detecting that the video frame of the PPT video file changes.

In the embodiment of the application, the terminal may detect whether a video frame of the PPT video file has changed by using an image recognition detection algorithm, for example, the image recognition detection algorithm may include a convolutional neural network, and may also include a deep learning neural network, and the like.

In some implementations, the implementation process of the terminal generating the dynamic image according to the playing sequence of the animation playing elements may include: the terminal acquires time point information of each animation playing element for finishing animation effect display, acquires a frame of video frame image according to the time point information of each animation effect display, and then generates a dynamic image according to the video frame image corresponding to each animation playing element. For example, the slide image 1 includes 3 animation playback elements, where the time point information when the animation playback element 1 completes the animation effect display is 0 second 00, the time point information when the animation playback element 2 completes the animation effect display is 1 second 20, and the time point information when the animation playback element 3 completes the animation effect display is 3 seconds 40, and the terminal respectively obtains video frame images corresponding to the 3 pieces of time point information, and then generates a dynamic image according to the 3 pieces of video frame images. In practical applications, considering that the time duration for displaying the dynamic image is a set time duration (e.g., 3 seconds), in this case, the video frame image sequences of 1 second may be respectively obtained according to the above-mentioned 3 time point information (i.e., an average obtaining manner), and then the dynamic image is generated according to the 3 video frame image sequences.

In some implementations, taking slide image 1 as an example, the playing duration of slide image 1 is 4 seconds, where the time point information of animation effect display completed by animation play element 1 is 0 second 00, the time point information of animation effect display completed by animation play element 2 is 1 second 20, and the time point information of animation effect display completed by animation play element 3 is 3 seconds 40, and the implementation process of generating dynamic images by the terminal according to the playing sequence of animation play elements may include: the terminal determines the display duration of each animation playing element according to the playing duration of the slide image 1 and the time point information of each animation playing element for finishing the animation effect display, and then determines the occupation ratio between the display duration and the playing duration of each animation playing element. Considering that the time length for displaying the dynamic image is a set time length (for example, 3 seconds), in this case, a corresponding video frame image sequence is obtained according to the ratio between the display time length and the playing time length of each animation playing element, and then the dynamic image is generated according to the obtained plurality of video frame image sequences.

The above-mentioned process of generating the moving image may be completed by the server, and then the server sends the moving image to the terminal for displaying.

Step S302, receiving a page turning instruction input by a user in the third playing display area, and turning the slide images according to the page turning instruction;

in this embodiment of the application, the page turning instruction may be a click operation of the user, a press operation, a slide operation, an operation for the page turning button shown in fig. 3B, or the like. For example, the user has performed one-press operation on the page turn button displayed in the third play display area. Then, after receiving a page turning instruction input by the user in the third broadcast display area, the terminal may perform a page turning up operation or a page turning down operation on the plurality of slide images to implement page turning of the slide images.

If the next slide image contains animation play elements after the current slide image is turned to the next slide image, then the next slide image is displayed according to the playing sequence of the animation play elements contained in the next slide image.

In this embodiment, the page turning instruction may include a normal page turning instruction and a fast page turning instruction.

Taking a common page turning instruction as an example, in some implementation manners, after receiving a page turning instruction input by a user, a terminal turns 1 slide image by a page turning operation once, for example, the number of the slide images is 10, and the images are respectively image 1, image 2, image 10, and a user performs a page turning operation for image 1, and at this time, image 2 is displayed on a display screen of the terminal, that is, image 2 is turned from currently displayed image 1. In the case where the number of slide images is small, it may be convenient for the user to better input a page turn determination instruction.

Taking a fast page turning instruction as a first fast page turning instruction as an example, if the number of the slide images contained in the PPT document is smaller than a first threshold value, turning the slide images currently displayed to a third slide image according to the first fast page turning instruction; the third slide image is the next N or the last N images of the slide image currently displayed. If the number of the slide images contained in the PPT document is larger than or equal to the first threshold value, turning from the slide image currently displayed to a fourth slide image; the fourth slide image is the lower M or upper M images of the slide image currently displayed; the N and the M are positive integers, and the N is smaller than the M.

In some implementations, the number of slide images that can be turned by one page-turning operation may be set according to how many slide images are, for example, when the number of slide images is smaller than a set first threshold (for example, the first threshold is 30), the number of slides that can be turned by one page-turning operation is N each time under the effect of the first fast page-turning instruction, for example, 3 slide images can be turned by one page-turning operation; for another example, when the number of slide images is greater than or equal to the set first threshold, the number of slide images is M each time under the effect of the first fast page turning instruction, and for example, 5 slide images may be turned by one page turning operation. The number of slide images turned each time may be N when the number of slide images is less than or equal to a set first threshold (e.g., the first threshold is 30), and M when the number of slide images is greater than the set first threshold.

Taking the example that the fast page turning instruction comprises a second fast page turning instruction, according to the second fast page turning instruction, turning up the image in the previous image set or turning down the image in the next image set from the image set where the slide image currently displayed is located; wherein, the flipping from the image set where the slide image is currently displayed to the image in the previous image set or the flipping to the image in the next image set, further comprises: and determining a plurality of image sets according to the relevance between the slide presentation contents in the PPT document.

The image in the flipped image set may be the first image or the key image in the image set, or the last image. The key image can be an image which can represent the content of the image set after being analyzed by a related content analysis algorithm.

In some implementation manners, from the user experience, when a user learns by using a PPT video file, in order to better understand a certain related knowledge point in the PPT document (that is, there is often a greater association degree between two adjacent slide presentation contents in the PPT document) so as to achieve the best learning effect, the user often has a higher requirement for adjusting the playing progress of the PPT video file. In this case, the terminal may obtain the association degree between two slide presentations in the PPT document, and then determine whether the association degree between two slide presentations is greater than a preset threshold (for example, the preset threshold may be 0.6, or may be 0.8, or the like), and cluster two slides when the association degree between two slide presentations is greater than the preset threshold, so as to obtain M image sets. Here, M is a positive integer greater than 0.

For example, taking the PPT document as "yearly summary" as an example, the PPT document contains 10 slides, where slide 1 forms a slide image set a "summary outline", slide 2, slide 3, slide 4, slide 5, and slide 6 form a slide image set B "work summary", slide 7 and slide 8 form a slide image set C "problem", and slide 9 and slide 10 form a slide image set D "new plan", that is, the PPT document can be divided into 4 slide image sets in content. Then, in this case, one slide image set is flipped by a page flip operation, and then, the user can input a page flip determination instruction in the slide images included in the slide image set to reduce the complexity of the page flip operation.

It should be noted that, after the slides are initially displayed in the third broadcast display area, the pages cannot be turned forward in general, because the current slide is the newest slide in the review video content by default, and the page turning can only be performed backward.

Step S304, receiving a page turning determination instruction input by a user aiming at the second slide image;

in this embodiment of the application, the page turning determination instruction may be triggered according to a third operation input by the user, where the third operation may be a click operation, a press operation, a slide operation, or the like. Here, by inputting a page-turning determination instruction to the second slide image, an adjusted playback node of the PPT video file may be determined, and then playback may be performed according to the adjusted playback node. The first operation, the second operation, and the third operation may be the same or different, and the present application is not particularly limited.

And S306, adjusting the playing progress of the PPT video file to the playing time stamp corresponding to the second slide image according to the page turning determination instruction, and playing.

In the embodiment of the application, after the terminal receives a page turning determination instruction input by a user for the second slide image, the terminal obtains the play timestamp corresponding to the second slide image from the mapping relationship between the slide images and the play timestamps, and then the terminal starts to play the PPT video file from the play timestamp corresponding to the second slide image in the third play display area, that is, the play progress of the PPT video file is adjusted to the play timestamp corresponding to the second slide image for playing, so that the adjustment of the play progress can be completed.

In practical applications, after the terminal receives a page turning determination instruction input by the user for the second slide image, the terminal starts to play the PPT video file in the third play display area from the play timestamp corresponding to the second slide image, and at the same time, the terminal may hide the second slide image, which may be understood as overlaying the PPT video file in the play state on the second slide image.

In order to facilitate better understanding of the technical solutions described in the present application, the following description is made with reference to specific examples. For example, taking the PPT video file as "yearly summary" as an example, the PPT video file contains 10 slide images, and specifically, the mapping relationship between the 10 slide images and the playing time stamp can be shown in table 2:

TABLE 2 mapping relationship between images and timestamps

In practical application, the terminal plays the PPT video file "summary in year", and the slide image played at the current time is image 5. The user inputs a playing control instruction for the PPT video file "yearly summary" in the playing state, the terminal displays the slide image (i.e. image 5) corresponding to the current playing time in the third playing display area of the PPT video file according to the playing control instruction after receiving the playing control instruction, at this time, the terminal receives a page turning operation input by the user in the third playing display area to turn the slide image, and then, the terminal receives a page turning determination instruction input by the user for the second slide image (image 2), the terminal obtains the playing time stamp (0min25s) corresponding to the second slide image (image 2) from the mapping relation (such as table 2) between the slide images and the playing time stamps, and then, the terminal starts playing the PPT video file from the playing time stamp (0min25s) corresponding to the second slide image in the third playing display area, thereby, the adjustment of the playing progress can be completed.

By implementing the embodiment of the application, the terminal can acquire the playing time stamp corresponding to the second slide image from the mapping relation between the slide images and the playing time stamps, then, the playing progress of the PPT video file is adjusted to the playing time stamp corresponding to the second slide image to be played, the playing progress bar of the PPT video file can be accurately adjusted to the node needing to be played, and the requirement of a user for quickly and accurately adjusting the playing progress of the PPT video file can be met.

In some implementations, in order to attract a lot of users to watch the PPT video file, a page of the video playing platform may display a high-quality PPT video file in a page recommendation list, where the page may be a top page of the application platform. In the prior art, a PPT video file is often presented in a page recommendation list in a static manner, and the realization manner cannot completely reflect the characteristics of the PPT video file, so that the eyes of a user cannot be attracted to the greatest extent. Based on this, in the embodiment of the application, when performing page recommendation display on a PPT video file, a key slide image in the PPT document is acquired, and a display motion map is generated according to the key slide image and displayed on a page with the display motion map, where the display motion map may be used to describe characteristics of the PPT video file. Therefore, when a user selects a PPT video file which is interested in, the user can quickly know which key contents are covered by the PPT video file by displaying the motion picture, and the clicking efficiency of the PPT video file can be improved.

In this embodiment of the application, the terminal may select one or more representative slide images from the generated slide images as key slide images, and then generate a display moving picture according to the key slide images.

In the embodiment of the application, the slide images can be screened according to the key content in the PPT document, so that one or more representative slide images can be screened and obtained as the key slide images. Specifically, after being analyzed by a related content analysis algorithm, one or more key slide images which can represent the content of the image set are obtained.

It should be noted that, in the embodiment of the present application, an execution sequence of generating a display motion picture by a terminal according to a key slide image is not limited, for example, in some implementations, when the terminal performs page recommendation display on a PPT video file, the slide images may be first screened to obtain the key slide image, and then the display motion picture is generated according to the key slide image; in some implementations, the display animation can also be generated from the key slide image when the page recommendation display is not performed on the PPT video file. It should be noted that the implementation manner and the execution sequence of generating the display images according to the key slide images are only an exemplary case, and are not exhaustive, and those skilled in the art may make other modifications or changes based on the technical solutions of the present application while understanding the spirit of the technical solutions of the present application, so long as the implemented functions and the achieved technical effects are similar to the present application, and the scope of the present application should be covered.

In some implementations, the PPT video file may include barrage information, which may be a note clip generated when the user last viewed the PPT video file, or comment information generated when the user viewed the PPT video file, for example, the comment information may include but is not limited to: "Tainiu! "," too wonderful! "and the like.

For example, as shown in fig. 3C, in the process of displaying, in a first play display region of a display interface, a video content corresponding to the video live broadcast data in a play mode, when the bullet screen information is in an activated state, the first play display region may be divided to obtain a first sub-region and a second sub-region, where the first sub-region and the second sub-region are both located in the first play display region and are not overlapped with each other, specifically, the bullet screen information is displayed in the first sub-region, the PPT video file is played in the second sub-region, and a region equivalent to an original PPT video file is scaled to the second sub-region to be played, so that the bullet screen information and the PPT video file can be displayed in different regions, and the bullet screen information is prevented from blocking the PPT document content. Or it can be understood from another direction that the blank area also belongs to the second sub-area in fig. 3C, that is, the first sub-area and the second sub-area constitute a first playing display area, but the PPT video file is not displayed in the whole second sub-area, the area of the original PPT video file is scaled to the second sub-area for playing, in order to ensure the playing ratio of the original PPT video file, the left and right edges of the second sub-area are blank areas (the blank areas refer to areas without content display, and may be full white areas or full black areas, etc.)

For another example, as shown in fig. 3D, in the process of displaying, in a first playing display region of a display interface, a video content corresponding to the video live broadcast data in a playing manner, when the bullet screen information is in an activated state, the first playing display region may be divided to obtain a first sub-region and a second sub-region, where the first sub-region and the second sub-region form the first playing display region, and the first sub-region and the second sub-region are not overlapped with each other, specifically, the bullet screen information is displayed in the first sub-region, and a PPT video file is played in the second sub-region, so that the bullet screen information and the PPT video file can be displayed in different regions, and the bullet screen information is prevented from blocking the document content.

In this embodiment of the present application, the bullet screen information being in the activated state may be triggered by the user turning on a "bullet screen switch button".

In some implementation manners, the size of the second sub-region may be obtained by scaling the display region of the PPT video file according to a preset scale, or by expanding a scaling edge and a blank region generated by an edge of the display region of the terminal after scaling the display region of the PPT video file according to the preset scale, which is not limited in this embodiment of the application.

In some implementation manners, the terminal can also detect a blank area in the PPT video file in a playing state through an intelligent algorithm, and display the bullet screen information in the blank area of the PPT video file.

Specifically, the terminal or the server may collect a large number of training samples of video content in advance, train one or more detection models or feature extraction models through the training samples, and different types of video content may correspond to different detection models or feature extraction models. The detection model or the feature extraction model is used for detecting and analyzing the video content to detect whether the video content contains information which is concerned or interested or should be regarded by the user.

For example, for educational video content, keywords such as "dividing point", "core", "attention", "examination point" and the like can be obtained as target feature information through training, and then whether the target feature information is included or not can be detected from video images or audio data, and if the target feature information is included, switching reminding information is output.

In some implementations, the output form of the switching reminder information includes, but is not limited to, highlighting the target information in the second display area (e.g., flashing a target button of a certain area several times), or playing a reminder switching voice to the user, etc.
