Detailed Description
In order to make the objects, technical solutions and advantages 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.
As shown in fig. 1, the video mouse interaction method according to the preferred embodiment of the present invention includes the following steps:
s10, opening a multi-channel video playing picture, receiving an operation of dragging the picture in playing by a mouse, and controlling the position of the multi-channel video to be exchanged randomly;
s20, when the mouse is detected to double click one path of video in the multi-path video, controlling the double-clicked one path of video to be displayed maximally;
and S30, dividing one path of video image into a plurality of virtual quadrants, executing a pan-tilt rotation function after receiving the mouse press, and amplifying or reducing the focus of the video through the mouse roller.
Specifically, for example, 16 paths of videos are played on a scheduling monitoring system platform, and the positions of the 16 paths of videos can be arbitrarily exchanged by dragging the played pictures with a mouse; double-clicking a certain path of video through a mouse to realize the maximization of the path of video; a video picture is divided into 8 virtual quadrants, the pan-tilt rotation function after a mouse is pressed is realized (for example, some cameras have the functions of remote control rotation, focusing, zooming and the like, and the functions are called pan-tilt control), and the zooming-in or zooming-out of the video focus by a mouse roller is realized.
Further, after the mouse interaction behavior is defined, after a handle of a Winform control needs to be handed to a bottom layer video SDK (Software Development Kit), the control function is not affected, and because the Winform control does not support the control to be transparent, the Winform control needs to be designed into a form of double panels (a Panel is a meaning of a Panel, and is generally used for receiving and drawing a video stream), the double panels are overlapped together, the upper Panel is used for drawing a video picture, the handle of the upper Panel needs to be handed to the SDK, and the lower Panel is mainly used for subscribing a mouse event; in order to prevent the upper Panel from blocking the lower Panel from acquiring a mouse event, the Enabled attribute of the upper Panel (the Enabled attribute is an attribute of the Panel control, and after the attribute is set to False, the Panel control cannot respond to any mouse and keyboard operation) needs to be set to False, so that the mouse interaction behavior of the whole player cannot be influenced no matter any video SDK is docked.
That is to say, when a video is accessed, a handle of a Winform control is transmitted to a software development kit for playing the video, and the software development kit draws a video picture to a control specified by a client; the Winform control comprises double Panel controls, namely a first Panel control and a second Panel control which is arranged below the first Panel control in an overlapped mode, wherein the first Panel control is used for drawing a video picture and transmitting a handle to the software development kit; and the second Panel control is used for subscribing mouse events and controlling mouse interaction. Setting an Enabled attribute in the first Panel control to False, wherein the Enabled attribute is used for docking a software development kit of any video, and avoiding influencing the mouse interaction behavior of the whole player; the Enabled attribute is an attribute of the first Panel control, and when the Enabled attribute is set to False, the first Panel control cannot respond to any mouse or keyboard operation.
As shown in fig. 2, in a background that a Winform control cannot support transparentization, the dual Panel control design manner in fig. 2 can avoid a problem that the Panel control cannot respond to mouse interaction due to the influence of the video SDK after the previous Panel control handle is transferred to the video SDK. The effect achieved is that the existence of double Panel controls cannot be sensed on the interface, the video is drawn on the front Panel control, and the interaction of the mouse is realized by the rear Panel control.
As shown in fig. 3, it is shown that the video picture is dragged to achieve the effect that the two video pictures are interchanged with each other; in many cases, the user wishes to monitor multiple cameras and can sort through the order he or she wants. The dragging mode can make a monitoring picture appear at any position (generally, video monitoring has a plurality of layout modes, such as 1 picture, 4 pictures, 9 pictures, 16 pictures, 32 pictures, etc., when only one path of camera is played, the layout is 16 pictures, and then the path of camera can be placed at any position of 16 positions through dragging).
As shown in fig. 4, it shows that a single video frame is double-clicked by a mouse, and the frame can be quickly viewed in a full screen.
As shown in fig. 5, by virtually dividing a video frame into 8 quadrants, when the left button of the mouse is pressed, the position where the mouse is pressed is detected, and the camera can be rotated in different directions (pan/tilt/zoom control).
For example, 4-way video pictures are opened; the video pictures need to be adjusted to change the sequence from 1234 to 2143, and the 1 picture needs to be dragged to the 2 pictures, and the 3 picture needs to be dragged to the 4 picture; the 1 picture lens needs to rotate about 30 degrees towards the left side, the 1 picture needs to be found, then the left mouse button is pressed in the middle of the left side of the 1 picture, the picture can rotate at the moment, and after the 30 degrees is reached, the left mouse button is released to stop rotating; the 2-picture lens needs to be amplified, the 2 pictures are selected firstly, then the mouse roller rolls forwards, and the lens is correspondingly amplified; if the maximum 1 picture is presented, the 1 picture is double clicked.
Further, the interactive behavior of the mouse may be extended to the keyboard.
Further, as shown in fig. 6, based on the above video mouse interaction method, the present invention also provides an intelligent terminal, which includes a processor 10, a memory 20, and a display 30.
