In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart of a video canvas control method provided by the present invention, and it should be noted that the video canvas control method according to the embodiment of the present invention is not limited to the steps and the sequence in the flowchart shown in fig. 1, and the steps in the flowchart may be added, removed, or changed according to different requirements.
As shown in fig. 1, the canvas control method for a video provided by the present invention includes the following steps:
s10, starting a video monitoring interface, and detecting whether the video monitoring interface receives the first click operation of the number of the trigger canvas.
In the embodiment of the invention, the data structure corresponding to the video monitoring interface is encapsulated through a VUE framework, that is, the data structure corresponding to the video monitoring interface is encapsulated through a development component library by adopting an VUE framework, then the type of a data interface is defined as an array object, file data is acquired, the file data is imported into the video monitoring interface through the data interface, and the video monitoring interface is formed through rendering and drawing, so that the video monitoring interface displays corresponding file data.
The vue framework adopted by the invention constructs the video monitoring interface, so that the video monitoring interface displaying the picture can be presented only by importing different file data without changing the data structure of the video monitoring interface, the requirements of different types of users or enterprises are met, the reusability is improved, and meanwhile, the vue framework realizes the responsive data binding and combined view assembly, thereby being easy to master, being convenient for being integrated with a third-party library or an existing project and greatly improving the popularization.
The data format of the file data is a tree list format, and each piece of data represents a node, which is equivalent to a branch on a tree. The data format of the file data includes fields such as label (directory structure), child (subdirectory), video data (video list data) fontColor (font color) catalog icon (directory icon) video icon (video icon) canvas options (canvas number).
When the video monitoring interface is rendered and drawn, whether a rtmp field is included in the sub-directory (children) field data in the imported file data is judged, if the rtmp field is included, the data corresponding to the sub-directory field is video data, and if the rtmp field is not included, the data corresponding to the sub-directory field is not video data and is a file, namely at least one root directory (similar to a folder) is displayed, and at least one sub-directory is included under each root directory. Specifically, as shown in fig. 2 (taking 4 canvas as an example), the rendered and drawn video monitoring interface includes a directory list area 102 and a playing area 101, and the positions of the directory list area and the playing area can be left and right sides of the video monitoring interface. The directory list area 102 is used for displaying the directory and the number of videos corresponding to the file data in a directory list form. I.e., the directory listing area 102 includes a search area 1021, a video directory area 1022, and a canvas selection area 1023. The search area 1021 is used for searching playable videos according to the directory name or the key sub-search, so that the search efficiency is improved. The video directory region 1022 displays imported file data in a file list format corresponding to a hierarchical format, and displays names (directory names) of folders, the number of videos, and video names and pause or play buttons corresponding to each video if each subfolder has a video. When a user clicks a button corresponding to the video for the first time, the video is synchronously played in each sub-playing area under the current canvas quantity, and when the button is clicked again, the video corresponding to each sub-playing area is switched from a playing state to a pause state. In this way, the state of the video display in the directory list area is synchronized with the pause or play state of the video in each sub-play area.
In some embodiments, the positions of the directory list area and the play area may be upper and lower sides.
The numerical value of the canvas quantity can be set to be single canvas, 4 canvases, 6 canvases, 9 canvases, 16 canvases and the like, and the canvas quantity set by default of the system is the single canvas. Of course, the numerical value is not limited, and when the number of the canvas is set, only the size and the definition of the picture of each sub-play area after the play area is divided need to meet the requirements of the user.
Further, the starting the video monitoring interface and detecting whether the video monitoring interface receives the first click operation of the number of the trigger canvas specifically includes:
s11, starting a video monitoring interface, wherein the video monitoring interface is initialized and displayed by a single canvas;
s12, detecting whether the video monitoring interface receives the first click operation of the number of the trigger canvas.
That is, the first click operation refers to the user determining the number of canvases to be displayed in the selection of the canvas selection area 1023, such as selecting 4 canvases.
The play area 101 is divided according to the number of the selected canvas.
S20, when the video monitoring interface is detected to trigger the first click operation of the canvas number, obtaining a first canvas number value, and dividing the playing area according to the first canvas number value, so that the video to be played is played synchronously in the sub-playing area corresponding to the first canvas number value.
That is, step S20 specifically includes:
s21, acquiring the first canvas quantity value, and averagely dividing the playing area according to the first canvas quantity value to obtain a sub-playing area corresponding to the first canvas quantity value;
s22, receiving a playing operation corresponding to the video triggering button, and acquiring a video to be played corresponding to the playing operation;
and S23, respectively displaying and synchronously playing the video to be played in each sub-playing area.
Specifically, the playing area is divided into sub-playing areas on average, and the number of the sub-playing areas is a first canvas number value. When the user clicks any video in the directory list area (i.e. the button displays the playing state), the video is played synchronously in each sub-playing area.
When the video in the directory list area is clicked again (i.e., the button displays the pause state), the video is paused in each sub-play area synchronously.
Further, in the playing process, a second click operation for triggering the number of the canvases again is detected, a second canvas number value corresponding to the second click operation is obtained, if 4 canvases are switched to 6 canvases, the original playing area is divided equally again according to the second canvas number value, and a new sub-playing area corresponding to the second canvas number value is obtained, namely, the new sub-playing area is divided into 6 sub-playing areas on average; and the video played in the atomic playing area synchronously plays the video being played again in each new sub-playing area.
When the number of the canvas is changed, the state of the video being played or the video being paused in each sub-playing area is not changed.
In some embodiments, if the play area is playing 6 videos, i.e. the first canvas amount value is 6, and the user selects to play only 4 videos again, i.e. the second canvas amount value is 4, the user is prompted to manually delete the video being played. That is, the user manually deletes the video corresponding to the canvas difference number.
In other embodiments, if the multi-canvas is switched to the single canvas, the user is prompted with a prompt dialog box "the video being played may not be played". When a positive answer is received, it automatically switches to a canvas to play or pause the video.
And if the single canvas is switched into the multiple canvases, the video to be played is played in each sub-playing area sequentially.
As shown in fig. 2, each sub-play area includes a pop-up window identification button 1011 and a close button 1012, and when it is detected that the user clicks the close button 1012, the video in the sub-play area corresponding to the close button 1012 is removed, and a blank state is displayed. Thus, the method can be used for playing new videos.
If the video is in the condition of multiple paintings, a plurality of sub-playing areas (the number of the paintings is smaller than that of the paintings) are randomly closed, and when the video is changed to be in the idle state, and when the video to be played is detected again, the played video is played in the sub-playing area in the idle state.
For another example, in the playing process, whether each sub-playing area receives the click operation of the popup identification button 1011 is detected; when it is detected that at least one sub-play area receives the click operation of the pop-up window identification button 1011, an editable window pops up, and the video which is being played and corresponds to the sub-play area is continuously played in the editable window.
That is, as shown in fig. 2, the user clicks the pop-up window identifier 1011, and at this time, the sub-play area corresponding to the clicking operation is displayed in the form of a pop-up window, that is, an editable window pops up, and the video in the atomic play area continues to play the video being played in the sub-play area in the editable window.
The editable window has editability, namely the window can be moved and adjusted in size and the like, is set in a user-defined mode according to user requirements, and is more humanized compared with the existing popup window which can only be set in a fixed area and cannot be changed in size.
Therefore, the pictures corresponding to the number of the canvas are automatically displayed according to the selection of the number of the canvas of the user, the presentation style of the video window can be changed according to the requirement, the video can be played, paused and switched at any time, and the like, and the user can conveniently use the video.
