Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.
The embodiment of the application provides a method for generating a spliced video cover, 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, a notebook computer and the like, or a fixed terminal such as a desktop computer and the like. The server may be a single server or a cluster of servers.
As shown in fig. 1, the process 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 acquired.
In an implementation, when a user wants to make a stitched video, an application that can make the stitched video can be opened on the terminal. After the application program is opened, corresponding operation can be performed, 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 number of video materials selected by the user can be set, and when the number of the video materials selected by the user is smaller than the minimum number of the video materials, the user is prompted to continue to select the video materials.
In one 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 program), 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 application is executed by the server, the terminal can send the identifier of the video material selected by the user from the online video material library to the server, and the server can acquire the 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 a plurality of video materials selected by a user are acquired, video stitching processing may be performed to obtain a stitched video. And when in splicing, video splicing processing can be carried out according to the selection sequence of the video materials to obtain spliced video.
As shown in fig. 5, the video stitching process may be performed by stitching the video material N according to the selection order of the video materials, where the video material N indicates that the video material is selected N.
In step 102, a plurality of target video materials are determined from a plurality of video materials.
In an implementation, after a plurality of video materials selected by a user are acquired, a plurality of target video materials can be determined in the plurality of video materials, and a spliced 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.
Wherein N is a set positive integer, and N should be less than the minimum number of video materials. For example, N may be 4.
In practice, the user selects the video material according to a certain selection order. When determining the target video material, selecting the video material with the sequence of the first N from the plurality of video materials, and determining the video material 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 target video materials.
In another possible implementation, the top N video materials with the highest play amount are determined as the plurality of target video materials from the plurality of video materials.
In an implementation, if the video material is selected from the online video material library, the online video material library also corresponds to the play amount of the stored video material. The top N (e.g., top 4) video materials with the highest play out of the plurality of video materials may be determined as the target video material.
The first N video materials with the highest playing amount are determined to be target video materials, so that the finally obtained spliced video cover contains the information of the target video materials, thereby improving the attraction of the spliced video and increasing the playing amount of the spliced video.
In another possible implementation, the N video materials are uniformly selected as the plurality of target video materials according to a selection order among the plurality of video materials.
In implementation, the target video material can be selected uniformly in the multiple video materials according to the selected sequence. For example, when the user selects 10 video materials, N is 4, it may be determined that the video materials selected in the 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, the target video material may also be determined by the user, that is, the user may mark the target video material when selecting the video material, and the terminal or the server may determine the target video material according to the mark in the video material.
At step 103, at least one target image frame is selected in each target video material.
Wherein, a target image frame can be selected from each target video material, and the target image frame can be any image frame of the target video material, for example, can be a cover of the target video material.
In implementations, the cover 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 more suitable for being used as the 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, and the information of the video materials contained in the spliced video can be expressed more clearly.
In step 104, the selected plurality of target image frames are subjected to image stitching processing, so as to obtain a stitched video cover.
In implementation, when performing the image stitching process on the 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), the plurality of target image frames may be stitched along a vertical direction, or the plurality of target image frames may be stitched in a manner of multiple rows and multiple columns (for example, two rows and two columns), which is not limited in the embodiment of the present application.
When a plurality of target image frames are subjected to splicing, it is necessary to perform splicing in a certain splicing order, particularly in a manner of performing splicing in the horizontal direction and the vertical direction. The principle of determining the splicing order can be as follows:
in one possible implementation manner, according to the selection sequence of the video materials corresponding to the target image frames, the image stitching process is performed on the target image frames, so as to obtain the stitched video cover.
The selection sequence of the video materials corresponding to the target image frames, namely the sequence of selecting the video materials by the user.
In practice, as shown in fig. 6, video material 1 represents the video material that was selected by user 1 st. The selected target video materials are the first 4 video materials selected by the user, the target image frames selected in the target video materials are the covers of the video materials, the covers of the video materials are spliced along 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 amounts of the video materials corresponding to the target image frames, the image stitching process is performed on the target image frames, so as to obtain the stitched video cover.
In the implementation, the image stitching process may be performed on the plurality of target image frames according to the order of the playing amounts of the video materials corresponding to the target image frames.
For example, each target image frame is subjected to the stitching processing in the horizontal direction, and the play amount of the video material corresponding to each target image frame gradually decreases in the order from left to right.
In another possible implementation, the image stitching process may also be performed on the plurality of target image frames in a random order.
In addition, after the generation of the spliced video cover, if a certain video material in the video material library is deleted, the corresponding target image frame in the spliced video cover may not be displayed normally, in one possible implementation, when the video material corresponding to the first target image frame in the spliced video cover is detected to be deleted, a second target image frame is selected from the video materials except for the plurality of target video materials. The first target image frame in the stitched video cover is replaced with the second target image frame. That is, if a certain target video material is deleted, one target video material is selected again from the non-target video materials, and a target image frame is selected from the target video material for replacing the first target image frame in the spliced video cover.
In another possible implementation manner, when it is detected that the video material corresponding to the first target image frame in the spliced video cover is deleted, a set picture is acquired, and the first target image frame in the spliced 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 a default set picture.
It should be noted that if a certain video material is deleted, corresponding processing is also required to be performed on the spliced video, specifically, each video material may be subjected to splicing processing again, so as to obtain a new spliced video. Alternatively, the portion of the video material that is deleted may be replaced with a default piece of video. Then, the new spliced video is processed based on the method for generating the spliced video cover in the embodiment, so as to obtain the new spliced video cover.
According to the method for generating the spliced video cover, the plurality of target video materials are determined from the plurality of video materials selected by the user, at least one target image frame is selected from each target video material, and finally, the selected plurality of target image frames are subjected to picture splicing processing to obtain the spliced video cover. Thus, the generated spliced video cover contains information of a plurality of video materials, and the expressed spliced video is large in information, so that a watching user can roughly know the content of the spliced video by watching the spliced video cover.

The acceleration sensor 311 can detect the magnitudes of accelerations on three coordinate axes of the coordinate system established with the terminal 300. For example, the acceleration sensor 311 may be used to detect components of gravitational acceleration on three coordinate axes. The processor 301 may control the display screen 305 to display a user interface in a landscape view or a portrait view according to the gravitational acceleration signal collected by the acceleration sensor 311. The acceleration sensor 311 may also be used for the acquisition of motion data of a game or a user.
The gyro sensor 312 may detect the body direction and the rotation angle of the terminal 300, and the gyro sensor 312 may collect the 3D motion of the user to the terminal 300 in cooperation with the acceleration sensor 311. The processor 301 may implement the following functions according to the data collected by the gyro sensor 312: motion sensing (e.g., changing UI according to a tilting operation by a user), image stabilization at shooting, game control, and inertial navigation.
The pressure sensor 313 may be disposed at a side frame of the terminal 300 and/or at a lower layer of the display 305. When the pressure sensor 313 is provided at the side frame of the terminal 300, a grip signal of the terminal 300 by a user may be detected, and left-right hand recognition or shortcut operation may be performed according to the grip signal. When the pressure sensor 313 is disposed at the lower layer of the display screen 305, control of the operability control on the UI interface can be achieved according to the pressure operation of the user on the display screen 305. The operability controls include at least one of a button control, a scroll bar control, an icon control, and a menu control.
The fingerprint sensor 314 is used to collect a fingerprint of a user to identify the identity of the user based on the collected fingerprint. Upon recognizing that the user's identity is a trusted identity, the user is authorized by the processor 301 to perform relevant sensitive operations including unlocking the screen, viewing encrypted information, downloading software, paying for and changing settings, etc. The fingerprint sensor 314 may be provided on the front, back or side of the terminal 300. When a physical key or a manufacturer Logo is provided on the terminal 300, the fingerprint sensor 314 may be integrated with the physical key or the manufacturer Logo.
The optical sensor 315 is used to collect the ambient light intensity. In one embodiment, processor 301 may control the display brightness of display screen 305 based on the intensity of ambient light collected by optical sensor 315. Specifically, when the intensity of the ambient light is high, the display brightness of the display screen 305 is turned up; when the ambient light intensity is low, the display brightness of the display screen 305 is turned down. In another embodiment, the processor 301 may also dynamically adjust the shooting parameters of the camera assembly 306 according to the ambient light intensity collected by the optical sensor 315.
A proximity sensor 316, also referred to as a distance sensor, is typically disposed on the front face of the terminal 300. The proximity sensor 316 is used to collect the distance between the user and the front of the terminal 300. In one embodiment, when the proximity sensor 316 detects a gradual decrease in the distance between the user and the front of the terminal 300, the processor 301 controls the display 305 to switch from the bright screen state to the off screen state; when the proximity sensor 316 detects that the distance between the user and the front surface of the terminal 300 gradually increases, the processor 301 controls the display screen 305 to switch from the off-screen state to the on-screen state.
