Fig. 2 is a flowchart of a method for acquiring a video cover according to an embodiment of the present disclosure. The embodiment is described by taking a terminal as an execution subject, and referring to fig. 2, the embodiment includes:
The server stores page data corresponding to each webpage. The page data includes a script text file (such as a JavaScript file), a style text file (such as a CSS file), and text data, etc., the script text file is used to control the jumping and displaying logic in the web page, and the style text file is used to control the layout and display style of the page data in the web page. In the embodiment of the present application, the video decoding tool may be stored in the page data as a Webassembly file.
In implementation, when a user opens a video upload page on a browser, a terminal sends a request for acquiring video upload page data to a server. And after receiving the request sent by the terminal, the server sends the page data of the video uploading page to the terminal. After the terminal receives page data of the video uploading page sent by the server, the browser displays the video uploading page based on the page data.
It should be noted that the video decoding tool in the embodiment of the present application may include multiple decoding manners, or may include only several fixed decoding manners, where the several fixed decoding manners may be decoding manners corresponding to videos supported by the video upload page. For example, as shown in fig. 1, the video formats supported by the video upload page only include four video formats, namely mp4, mov, mkv, and webm, and therefore, the video decoding tool may only include decoding modes corresponding to the four video formats, so that the decoding modes included by the video decoding tool can be set specifically according to the characteristics of the video upload page, and meanwhile, the occupied space of the video decoding tool is reduced.
The target video in the embodiment of the application is obtained through two encoding processes, the first encoding process is to encode decoded video frames to obtain video frames in an intermediate format, and the second encoding process is to encode all the video frames in the intermediate format to obtain the target video. Since the target video in this application is obtained through two encoding processes, two decoding processes are required. The first decoding process corresponds to step 202 in the present embodiment, and the second decoding process corresponds to step 203.
The intermediate format video frame described above is a video frame obtained by encoding a decoded video frame, but both the intermediate format video frame and the decoded video frame are video frames, and the difference is that the data amount corresponding to the intermediate format video frame is smaller than the data amount of the decoded video frame.
Optionally, after the terminal determines the target video to be uploaded, the target video may be decoded for the first time by the video decoding tool. The method comprises the following specific steps: and after the video decoding tool is loaded, decoding the target video for the first time based on the video coding tool to obtain a plurality of video frames with intermediate formats.
Wherein, the target video is the video that the user needs to upload.
In implementation, a video uploading instruction is received at a terminal, a storage address of a target video in a terminal hard disk is determined, the target video can be found according to the storage address, a binary target video is read and stored in a terminal memory, and finally a loaded video decoding tool is used for decoding the target video in the terminal memory for the first time to obtain a plurality of video frames with intermediate formats.
Optionally, after the terminal finishes uploading the target video, the target video is decoded for the first time by the video decoding tool to obtain a plurality of video frames in the intermediate format. The method comprises the following specific steps: and after the video uploading instruction is received, loading a video decoding tool in the page data, and after the target video is uploaded, decoding the target video for the first time based on the video coding tool to obtain a plurality of video frames with intermediate formats.
For example, as shown in fig. 3, when the user clicks on a selection video file, the video file selection page is entered. And the user selects the video file in the video file selection page, clicks a determined button on the video file selection page, and returns to the video uploading page. And meanwhile, taking the instruction corresponding to the determined button as a video uploading instruction, and loading a video decoding tool in the page data. After the video decoding tool is loaded, or after the video decoding tool is loaded and the target video is uploaded, the loaded video decoding tool is used for decoding the target video for the first time to obtain a plurality of video frames with intermediate formats.
And 203, based on the video decoding tool, performing secondary decoding on the video frame with the intermediate format corresponding to the at least one preset time point to obtain at least one first decoded video frame.
The page data may store at least one preset time point, and the terminal may acquire the at least one preset time point when receiving the page data.
In implementation, the terminal acquires at least one preset time point in the page data, and performs second decoding on the video frame in the intermediate format corresponding to the at least one preset time point based on the video decoding tool to obtain at least one first decoded video frame.
Optionally, determining frame numbers respectively corresponding to at least one preset time point according to the at least one preset time point and the frame interval duration; determining memory addresses corresponding to the intermediate format video frames respectively corresponding to at least one preset time point according to the frame number respectively corresponding to the at least one preset time point, the initial memory address corresponding to the first intermediate format video frame and the frame data amount corresponding to the intermediate format video frame; and performing secondary decoding on the video frame of the intermediate format indicated by the memory address based on the video decoding tool to obtain at least one first decoded video frame.
The frame interval duration corresponding to each intermediate format video frame is equal, and the frame interval duration is preset by a technician, for example, the frame interval duration is 10 ms. The terminal allocates equal storage space for each intermediate format video frame, i.e. the amount of frame data corresponding to each intermediate format video frame is equal. When the terminal reads the target video stored in the hard disk into a binary target video and stores the binary target video in the memory, the terminal can directly acquire the initial memory address corresponding to the target video.
In implementation, for any one of at least one preset time point, determining a frame number corresponding to the preset time point according to the preset time point and a preset frame interval duration. And determining the number of the frames spaced between the video frame in the intermediate format corresponding to the preset time point and the video frame in the first intermediate format according to the frame sequence number corresponding to the preset time point. Then, multiplying the frame number and the data volume to obtain a product of the frame number and the data volume, adding the product and the initial memory address to obtain a sum of the product and the initial memory address, and further determining the memory address corresponding to the preset time point. And determining the memory address corresponding to each preset time point by the same method. And the terminal uses a video decoding tool to carry out secondary decoding on the video frame with the intermediate format indicated by the memory address to obtain at least one first decoded video frame.
In the embodiment of the present application, the preset time point which does not meet the condition may also be deleted. The terminal stores the duration corresponding to the target video, or reads the duration corresponding to the target video when the target video is uploaded on the video uploading page. Before the terminal determines the frame number corresponding to at least one preset time point, the maximum time point corresponding to the target video is determined according to the duration corresponding to the target video. And reserving preset time points which are less than or equal to the maximum time point, and determining first decoded video frames corresponding to the preset time points respectively based on the reserved preset time points. Deleting the preset time points which are larger than the maximum time point, and not determining the first decoding video frames respectively corresponding to the preset time points.
Or the terminal stores the maximum frame number corresponding to the target video. After determining the frame numbers respectively corresponding to at least one preset time point, the terminal may further obtain a maximum frame number corresponding to the target video, reserve the frame numbers less than or equal to the maximum frame number, and determine, based on the reserved frame numbers, first decoded video frames respectively corresponding to the reserved frame numbers. Deleting the frame numbers greater than the maximum frame number without performing the step of determining the first decoded video frames corresponding to the frame numbers respectively.
Or the terminal stores the termination memory address corresponding to the target video. The step of obtaining the termination memory address comprises the following steps: when the terminal stores the binary file corresponding to the target video in the terminal memory, the terminal can also obtain the termination memory address corresponding to the video. After the terminal determines the memory addresses corresponding to the video frames in the intermediate format respectively corresponding to at least one preset time point, the terminal determines whether the memory addresses are before the termination memory address. And if the memory address is before the termination memory address, performing second decoding on the video frame in the intermediate format indicated by the memory address based on the video decoding tool to obtain at least one first decoded video frame. If the memory address is after the terminating memory address, the memory address is deleted.
Optionally, displaying at least one first decoded video frame on the video upload page; when a selection instruction for a target decoded video frame among the at least one first decoded video frame is received, the target decoded video frame is determined as a cover image of the target video.
In an implementation, at least one first decoded video is displayed on a video upload page. And when the terminal receives the selection instruction, determining the target decoding video frame corresponding to the selection instruction as a cover image of the target video.
Taking the example that the terminal acquires a preset time point in the page data, that is, after the second decoding, only one first decoded video frame can be obtained, so that the terminal can directly display the first decoded video frame as a cover image of the target video on the video uploading page, and the specific display result is shown in fig. 3.
Optionally, when a manual cover searching instruction is received, displaying a time axis corresponding to the target video; when a selection instruction corresponding to a target time point on a time axis is received, determining at least one video frame in an intermediate format from a plurality of video frames in the intermediate format stored in a terminal memory based on the target time point; performing secondary decoding on the at least one video frame with the intermediate format based on a video decoding tool to obtain at least one second decoded video frame; and acquiring a target decoded video frame as a cover image of the target video in the at least one second decoded video frame.
The manual cover searching instruction may be triggered by a virtual key on the terminal, may also be triggered by an entity key on the terminal, and may also be triggered by a specific gesture of the user, which is not specifically limited in this application. For example, when the user operates the mouse to click on the cover image on the page, a manual cover finding instruction is triggered.
In implementation, when none of the decoded video frames displayed by the video upload page is the cover page desired by the user, the user may click on a certain position on the video upload page, or some operation, to trigger a manual cover page search instruction. And the terminal receives a manual cover searching instruction and displays the time axis, so that the user can select a time point on the time axis. When the terminal receives a selection instruction corresponding to a target time point on a time axis, at least one video frame in an intermediate format is determined in a plurality of video frames in the intermediate format stored in a terminal memory based on the target time point. And the terminal uses the video decoding tool to carry out secondary decoding on the video frame with the at least one intermediate format to obtain at least one second decoded video frame. And the terminal displays at least one second decoded video frame, and takes the target decoded video frame as a cover image of the target video when receiving a selection instruction of the target decoded video frame.
As shown in fig. 6, when the user operates the mouse to click on a certain position on the page, a manual cover searching command is triggered. After triggering the manual find cover instruction, the terminal may display a manual find cover page that displays a timeline, a time control on the timeline, 6 initial second decoded video frames, and a plurality of buttons. The time control is used for a user to select time on the time axis, and the initial second decoded video frame is a second decoded video frame determined based on the initial time point. The user drags the time control to make the time control stay at a certain position. At this time, when the terminal detects that the staying time of the time control at a certain position exceeds a preset numerical value, the terminal can determine a target time point corresponding to the position, further determine at least one second decoded video frame according to the target time point, and display a thumbnail corresponding to the second decoded video frame on the manually searched cover page. And displaying the thumbnail corresponding to the 6 second decoded video frames on the manual searching cover page, and displaying the enlarged image of the second decoded video frames on the manual searching cover page after receiving the selection instruction of the thumbnail corresponding to the first second decoded video frame. And when the user clicks the determining button, taking the second decoded video frame as a cover image of the target video.
The embodiment of the application provides two modes for determining at least one video frame with an intermediate format based on a target time point, and the specific steps are as follows:
in the first mode, a first video frame corresponding to a target time point, and a preset number of video frames before and a preset number of video frames after the first video frame are determined from a plurality of video frames in an intermediate format stored in a terminal memory.
Wherein the preset number may be preset empirically by the technician, for example, the technician sets the preset number to 5.
In implementation, in a plurality of intermediate format video frames stored in a terminal memory, a frame number corresponding to a target time point is determined according to the target time point and a frame interval duration, and then a first video frame corresponding to the target time point, and a preset number of video frames before and a preset number of video frames after the first video frame are determined.
The video frames with the preset number of front/back of the first video frame may be the video frames with the preset number of intermediate formats adjacent to the front/back of the first video frame, or the video frames with the preset number of intermediate formats not adjacent to the front/back of the first video frame.
In order to ensure that the difference between a preset number of video frames in the intermediate format is large, the similarity between the video frames in the intermediate format can be detected in advance, and then the video frames in the intermediate format with the similarity smaller than a preset threshold value are recommended to a user. Taking the determination of n nonadjacent video frames of the intermediate format after the first video frame as an example, the terminal is provided with a similarity calculation model, the similarity calculation model calculates the similarity between the first video frame and the video frame of the intermediate format after the first video until determining a second video frame of which the similarity with the first video is lower than a preset threshold, and the second video frame is taken as a video frame of the first intermediate format in the n nonadjacent video frames. And then, the similarity calculation model calculates the similarity of the second video frame and the video frame of the intermediate format behind the second video frame until a third video frame with the similarity lower than the preset similarity between the first video frame and the second video frame is determined, and the third video frame is used as the video frame of the second intermediate format in the next n nonadjacent video frames of the intermediate format. By the method, the video frame of the nth intermediate format in the next n nonadjacent video frames of the intermediate format is determined. Wherein n represents a preset number and is an integer greater than or equal to 1.
The similarity calculation model may be a machine learning model or a non-machine learning model. For example, the similarity calculation model may calculate a euclidean distance between any two video frames in the intermediate format, and calculate the similarity between the two video frames in the intermediate format based on the euclidean distance and the Softmax function.
In an alternative scheme, after a first video frame corresponding to a target time point is determined and before a preset number of video frames before and a preset number of video frames after the first video frame are determined, the terminal analyzes the content of the video, and then classifies the video according to the content of the video to obtain a category corresponding to the video.
