Detailed Description
In order that the above-mentioned objects, features and advantages of the present application may be more clearly understood, the solution of the present application will be further described below. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be practiced in other ways than those described herein; it is to be understood that the embodiments described in this specification are only some embodiments of the present application and not all embodiments.
At present, in order to keep the fluency of the video dynamic cover, a plurality of repeated video frame pictures can be added in a reverse order and played in sequence to form a motion picture effect. Assume that the resource file used to generate the video motion cover includes 6 video frame pictures, with indices of 0, 1, 2, 3, 4, 5, respectively. In the related art, a plurality of repeated video frame pictures may be added in reverse order after the 6 th video frame picture. For example, the 5 th video frame picture, the 4 th video frame picture and the 3 rd video frame picture may be added in sequence after the 6 th video frame picture to form 9 video frame pictures.
As shown in fig. 1, the 7 th video frame picture (video frame picture with subscript 6) and the 5 th video frame picture (video frame picture with subscript 4) are the same video frame picture, the 8 th video frame picture (video frame picture with subscript 7) and the 4 th video frame picture (video frame picture with subscript 3) are the same video frame picture, and the 9 th video frame picture (video frame picture with subscript 8) and the 3 rd video frame picture (video frame picture with subscript 2) are the same video frame picture.
When generating the video dynamic surface, the 9 video frame pictures can be played circularly according to the sequence from subscript 0 to subscript 8, and then from 0 to 8. Due to the existence of repeated video frame pictures, the video dynamic cover occupies more storage space, consumes more bandwidth flow and occupies larger device memory when the video dynamic cover is displayed, and the problem is more prominent for low-end mobile devices.
In order to solve the problem, embodiments of the present application provide a dynamic cover generation method, an apparatus, an electronic device, a medium, and a program product, which can reduce a storage space occupied by a video dynamic cover on the premise of ensuring smooth visual experience of the video dynamic cover, and reduce occupied memory and traffic consumption when playing the video dynamic cover.
Fig. 2 is a schematic diagram showing a system architecture of an exemplary application environment to which the video dynamic cover generation method of the embodiment of the present application can be applied.
As shown in fig. 2, system architecture 100 may include terminal device 101, terminal device 102, one or more of terminal devices 103, network 104, and server 105. Network 104 is the medium used to provide communication links between terminal device 101, terminal device 102, terminal device 103, and server 105. Network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few. The terminal devices 101, 102, 103 may be various electronic devices having a display screen, including but not limited to desktop computers, portable computers, smart phones, tablet computers, and the like. It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation. For example, server 105 may be a server cluster comprised of multiple servers, or the like.
The video dynamic cover generation method provided by the embodiment of the present application may be executed by a terminal device, and after the terminal device 101, the terminal device 102, and the terminal device 103 generate a video dynamic cover according to the video dynamic cover generation method provided by the embodiment of the present application, a video file and a video dynamic cover of the video file may be uploaded to the server 105.
Referring to fig. 3, fig. 3 is a flowchart of a method for generating a video dynamic cover page in an embodiment of the present application, which may include the following steps:
s310, obtaining a preset number of continuous video frame pictures in the video file.
The video file is composed of a plurality of video frame pictures, and a preset number of video frame pictures can be acquired from the video file to generate a video dynamic cover. The preset number may be the same as the number of resource files used by the aforementioned "reverse addition method", and may be, for example, 5, 6, 7, or the like. Therefore, the content displayed by the video dynamic cover can not be reduced while the video dynamic cover is realized.
For example, the video dynamic cover in fig. 1 is composed of 9 video frame pictures, including 6 original video frame pictures and 3 repeated video frame pictures. In the embodiment of the present application, duplicate video frame pictures (video frame pictures with subscripts of 6, 7, and 8) can be removed, and as shown in fig. 4, 6 original video frame pictures are used for generating a video dynamic cover.
And S320, performing reciprocating circular playing on the preset number of video frame images according to the time sequence of the preset number of video frame images to generate a dynamic cover of the video file.
In the embodiment of the application, because the preset number of video frame pictures do not contain repeated video frame pictures, if the video frames are played according to the existing sequential playing mode, an obvious abrupt feeling can be generated. Therefore, the playing mode is changed from sequential playing to reciprocating playing to keep smooth visual effect. Referring to fig. 5, fig. 5 is a schematic diagram of performing a reciprocating circular playing on a preset number of video frame pictures in the embodiment of the present application, where the number of the video frame pictures is 6, and after playing from a video frame picture with a subscript of 0 to a video frame picture with a subscript of 5, the video frame pictures are played in a reverse order to the video frame picture with a subscript of 0, and the above process is repeated, so as to implement the reciprocating circular playing.
It should be noted that, since the video frame picture with the subscript of 8 in fig. 1 is the same as the video frame picture with the subscript of 2, when the video frame picture with the subscript of 0 is returned from the video frame picture with the subscript of 8 for playing, that is, when the video frame picture with the subscript of 2 jumps directly to the video frame picture with the subscript of 0, the video frame picture with the subscript of 1 jumps. Compared with the playing mode shown in fig. 1, in the above-mentioned reciprocating playing process, the adjacent video frame pictures are all continuous, so that the problem of picture skipping does not occur, and the smooth effect can be better realized.
According to the method for generating the dynamic cover of the video, after the preset number of video frame pictures in the video file are obtained, the preset number of video frame pictures are played in a reciprocating circulating mode, namely, after the first video frame picture of the preset number of video frame pictures is played to the last video frame picture in sequence, the last video frame picture is played to the first video frame picture in a reverse sequence, the first video frame picture is played to the last video frame picture in sequence, and the like, and the video is played in a reciprocating circulating mode according to the mode. On one hand, because adjacent video frame pictures are continuous in the playing process, the smoothness of a dynamic front cover of the video can be ensured, and the problem of picture flashing cannot occur; on the other hand, because the repeated video frame pictures are not added, namely the repeated video frame pictures are reduced, the storage space occupied by the dynamic cover can be smaller, the flow consumed by network transmission can be effectively reduced, and meanwhile, a smaller memory can be occupied when the dynamic cover is displayed. Taking a single video file as an example, about 1.5M of memory can be saved, and the memory occupation is effectively reduced.
Referring to fig. 6, fig. 6 is a flowchart of another method for generating a video dynamic cover page in the embodiment of the present application, which may include the following steps:
s610, obtaining a preset number of continuous video frame pictures in the video file.
In the embodiment of the application, the video file can be a video file shot by a user in real time, and the user can shoot a target object through the terminal equipment. Accordingly, the terminal device generates a video file in response to a shooting operation for a target object. The video file may also be a locally pre-stored video file, and the locally stored video file may be directly obtained, or the locally stored original video file may also be obtained, and the original video file is edited to obtain the video file.
In an alternative embodiment, the user may be provided with an interface for selecting video frame pictures, and the user may select the video frame picture of interest in the interface as the resource file of the video dynamic cover. Specifically, the user may first click a button for displaying a video frame picture, and the terminal device displays a plurality of video frame pictures in the video file in response to a display operation for each video frame picture in the video file. And then, the user selects the video frame picture of interest from the plurality of video frame pictures and carries out click operation, and the terminal equipment responds to the selection operation aiming at the plurality of video frame pictures to obtain a continuous preset number of video frame pictures.
In yet another alternative embodiment, a preset number of video frame pictures may also be automatically acquired. For example, scene recognition may be performed on each video frame picture in the video file, and a key video frame picture in the video file may be determined based on the scene recognition result. The key video frame picture generally refers to a video frame picture containing important content, and may be one or a plurality of pictures. For example, for a person video, a video frame picture containing a key action of the person may be taken as a key video frame picture.
And then, acquiring a preset number of continuous video frame pictures containing the key video frame pictures from the video file. For example, one or more frames of video frames are selected before and/or after the key video frame to obtain a preset number of consecutive video frames.
And S620, performing reciprocating circular playing on the preset number of video frame images according to the time sequence of the preset number of video frame images to generate a dynamic cover of the video file.
The specific process of performing the reciprocating playing of the preset number of video frame pictures can be referred to the description in S320 in the embodiment of fig. 3, and is not described herein again.
And S630, performing scene recognition on a preset number of video frame pictures to obtain a scene recognition result, determining one or more text messages matched with the scene recognition result, and displaying the one or more text messages.
In the embodiment of the application, after the video dynamic cover is obtained, in order to better embody the content represented by the video dynamic cover, related text information can be added. For example, a mapping relationship between a scene and text information may be established in advance, and a scene recognition result may be obtained by performing scene recognition on a preset number of video frame pictures. And determining text information matched with the scene recognition result according to the mapping relation, and displaying the text information for the user to select.
For example, if a scene of classroom learning is identified, it may be determined that the textual information matching the scene may be: "good learning, upward every day"; or "carefully learned samples are truly lovely" and the like. If a scene of a birthday is identified, it may be determined that the text information matching the scene may be "happy birthday" or the like.
And S640, responding to the selection operation aiming at one or more text messages, acquiring the target text message, and displaying the target text message in the dynamic cover page.
If the number of the displayed text messages is multiple, the user can select one text message from the multiple text messages, or select two or more text messages as the target text message, and display the target text message in the dynamic cover page. For example, the target text information may be displayed in a preset area of the dynamic cover page, and of course, the user may adjust the display area of the target text information.
S650, if the preset number of video frame pictures contain characters, performing expression recognition on the characters to obtain expression recognition results, determining one or more expression images matched with the expression recognition results, and displaying the one or more expression images.
In the embodiment of the application, if the preset number of video frame pictures contain characters, after the video dynamic cover is obtained, related expression images can be added to better reflect the mood of the characters in the video dynamic cover. The character in the video frame picture can be subjected to expression recognition, and expression recognition results are obtained, for example, the expression recognition results can include anger, nausea, fear, happiness, sadness, surprise, neutrality and the like. Similarly, one or more expression images matching the representation recognition result may be determined and displayed for selection by the user.
And S660, responding to the selection operation aiming at one or more expression images, acquiring a target expression image, and displaying the target expression image in the dynamic cover.
The user may select an expression image of interest from the one or more expression images as a target expression image and display the target expression image in the dynamic cover page. In this way, the content of the video motion cover can be presented more vividly.
According to the method for generating the video dynamic cover, after the continuous preset number of video frame pictures in the video file are obtained, the video dynamic cover is generated in a reciprocating circulating playing mode, the smoothness of the dynamic cover can be guaranteed, the repeated video frame pictures are reduced, the storage space occupied by the video dynamic cover is smaller, the flow consumed by network transmission can be effectively reduced, and the occupied memory is reduced when the dynamic cover is displayed. In addition, after the video dynamic cover is generated, text information or expression images can be added into the video dynamic cover, so that a user watching the video dynamic cover can know the content of a video file more accurately, and an interested video file can be selected accurately for watching.
