Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The embodiment of the application provides a method for generating a cover of a spliced video, which can be realized by a terminal or a server. The terminal can be a mobile terminal such as a mobile phone, a tablet computer and a notebook computer, and can also be a fixed terminal such as a desktop computer. The server may be a single server or a cluster of servers.
As shown in fig. 1, the processing flow of the method for generating a stitched video cover may include the following steps:
in step 101, a plurality of video materials selected by a user are obtained.
In an implementation, when a user wants to make a spliced video, an application program that can make the spliced video can be opened on the terminal. After the application program is opened, corresponding operation can be carried out, so that the terminal displays the video material library, and a user can select a plurality of video materials in the video material library. In addition, the minimum video material quantity selected by the user can be set, and when the quantity of the video materials selected by the user is smaller than the minimum video material quantity, the user is prompted to continue selecting the video materials.
In a possible implementation manner, the video material library is a local video material library, and when the method provided by the embodiment of the present application is executed by a server (the server may be a background server of an application), the terminal may send the video material selected by the user in the local video material library to the server. When the method provided by the embodiment of the application is executed by the terminal, the terminal can directly acquire a plurality of video materials from the local video material library.
In another possible implementation manner, the video material library is an online video material library, and when the method provided by the embodiment of the present application is executed by a server, a terminal may send an identifier of a video material selected by a user from the online video material library to the server, and the server may obtain a corresponding video material from the online video material library based on the received identifier. When the method provided by the embodiment of the application is executed by the terminal, the terminal can acquire the video material selected by the user from the online video material library.
It should be noted that after the multiple video materials selected by the user are obtained, video splicing processing may be performed to obtain a spliced video. When splicing, video splicing processing can be performed according to the selection sequence of the video materials to obtain a spliced video.
The flow of the video splicing process can be as shown in fig. 5, where the video material N indicates that the video material is selected nth, and the spliced video is spliced according to the selection sequence of the video materials.
In step 102, a plurality of target video materials are determined among a plurality of video materials.
In implementation, after a plurality of video materials selected by a user are acquired, a plurality of target video materials can be determined from the plurality of video materials, and a stitched video cover is generated by using image frames in the target video materials.
The rules for determining the plurality of target video materials among the plurality of video materials may be as follows:
in one possible implementation, the first N video materials selected by the user are determined among the plurality of video materials as the plurality of target video materials.
Where N is a positive integer, and N should be less than the minimum video material amount. For example, N may be 4.
In implementation, when the user selects the video material, the video material is selected according to a certain selection sequence. When the target video material is determined, the video material with the top N sequence selected from the plurality of video materials may be determined as the target video material.
For example, if the user selects 10 video materials, the first, second, third and fourth selected video materials may be determined as the target video materials.
In another possible implementation manner, the first N video materials with the highest playing amount are determined among the plurality of video materials as the plurality of target video materials.
In practice, if the video material is selected from an online video material library, the online video material library will also have a corresponding amount of video material stored therein. The first N (e.g., the first 4) video materials with the highest playability among the plurality of video materials may be determined as the target video materials.
The first N video materials with the highest playing quantity are determined as the target video materials, so that the finally obtained spliced video cover contains the information of the target video materials, the attraction of the spliced video can be improved, and the playing quantity of the spliced video is increased.
In another possible implementation manner, the N video materials are uniformly selected from the plurality of video materials as the plurality of target video materials according to the selection order.
In implementation, the target video material may be selected uniformly in the plurality of video materials according to the selection order. For example, if the user selects 10 video materials and N is 4, it can be determined that the video materials having the selection order of 1, 4, 7, and 10 are the target video materials.
In another possible implementation, N video materials are randomly selected from the plurality of video materials as the target video material.
In another possible implementation manner, the target video material may also be determined by the user, that is, when the user selects the video material, the target video material may also be marked, and then the terminal or the server may determine the target video material according to the mark in the video material.
In step 103, at least one target image frame is selected in each target video material.
One target image frame may be selected from each target video material, and the target image frame may be any image frame of the target video material, for example, may be a cover page of the target video material.
In implementation, the cover page of each target video material may be taken as a target image frame. Because the covers of the video materials are generally selected image frames which are suitable for being used as covers, and other users can know the video materials in the video material library through the covers, the covers of a plurality of video materials in the spliced video are selected as target image frames, so that the information of the video materials contained in the spliced video can be more clearly expressed.
In step 104, the selected target image frames are subjected to image stitching processing to obtain a stitched video cover.
In an implementation, when performing picture stitching processing on a plurality of target image frames, the plurality of target image frames may be stitched along a horizontal direction (as shown in fig. 6 and 7), or the plurality of target image frames may be stitched along a vertical direction, or the plurality of target image frames may be stitched in multiple rows and multiple columns (for example, two rows and two columns), which is not limited in this embodiment of the present invention.
When the target image frames are spliced, the target image frames need to be spliced according to a certain splicing sequence, particularly in a manner of splicing along the horizontal direction and the vertical direction. The determination principle of the splicing order can be as follows:
in a possible implementation manner, according to the selection sequence of the video materials corresponding to the plurality of target image frames, the plurality of target image frames are subjected to image splicing processing, and a spliced video cover is obtained.
The selection sequence of the video materials corresponding to the target image frames, that is, the sequence in which the user selects the video materials, is described.
In implementation, as shown in fig. 6, video material 1 represents the video material that is the 1 st selected video material by the user. The selected target video materials are the first 4 video materials selected by the user, the target image frame selected from the target video materials is the cover of the video materials, the covers of the video materials are spliced in the horizontal direction, and the selection sequence of the video materials corresponding to the covers is gradually increased along the sequence from left to right.
In another possible implementation manner, according to the order of the playing amount of the video material corresponding to the plurality of target image frames, the plurality of target image frames are subjected to image splicing processing, so that a spliced video cover is obtained.
In implementation, the image stitching processing may be performed on the plurality of target image frames according to the size sequence of the playing amount of the video material corresponding to the target image frames.
For example, each target image frame is processed by stitching along the horizontal direction, and the playing amount of the video material corresponding to each target image frame gradually decreases along the sequence from left to right.
In another possible implementation manner, the multiple target image frames may be subjected to image stitching processing in a random order.
In addition, after the generation of the stitched video cover, if a certain video material in the video material library is deleted, which may cause that the corresponding target image frame in the stitched video cover cannot be displayed normally, in a possible implementation manner, when it is detected that the video material corresponding to the first target image frame in the stitched video cover is deleted, a second target image frame is selected from the video materials except for the plurality of target video materials. And replacing the first target image frame in the spliced video cover with the second target image frame. That is, if a certain target video material is deleted, a target video material is reselected from the non-target video materials, and a target image frame is selected from the target video material to replace the first target image frame in the stitched video cover.
In another possible implementation manner, when it is detected that the video material corresponding to the first target image frame in the stitched video cover is deleted, a set picture is obtained, and the first target image frame in the stitched video cover is replaced by the set picture. That is, if some target video material is deleted, the first target image frame in the stitched video cover is replaced with the default setting picture.
It should be noted that if a certain video material is deleted, corresponding processing needs to be performed on the spliced video, and specifically, each video material may be subjected to splicing again to obtain a new spliced video. Alternatively, the deleted portion of the video material may be replaced with a default piece of video. Then, the obtained new spliced video is processed based on the method for generating the spliced video cover in the above embodiment, so as to obtain a new spliced video cover.
According to the method for generating the spliced video cover, a plurality of target video materials are determined from a plurality of video materials selected by a user, at least one target image frame is selected from each target video material, and finally, the selected target image frames are subjected to image splicing processing to obtain the spliced video cover. Therefore, the generated spliced video cover contains the information of the plurality of video materials, and the information of the expressed spliced video is large, so that the watching user can roughly know the content of the spliced video by watching the spliced video cover.
