Embodiment Construction

[0015] Such as figure 1 As shown, the present invention adopts the following steps to realize a method for freely switching computer cameras on the web page.

[0016] Step 1. Define the required tags on the page, define the tag to display the video (video), and define the drop-down tag (select) to select the camera option;

[0017]

[0018] Video Options: .

[0019] Step 2, using mediaDevices.enumerateDevices to collect the information of multimedia input and output devices available on the computer;

[0020] var videoElement = document. querySelector('video');

[0021] var videoSelect = document. querySelector('select#videoSelect');

[0022] navigator.mediaDevices.enumerateDevices().then(oppendMedia).then(callVideo).catch(function (err){

[0023] console.log('Error: ', err);

[0024]}).

[0025] Step 3. Obtain the collected computer camera information, and add the computer camera information to the drop-down option cyclically;

[0026] function oppendMedia(device...

Abstract

The invention relates to the technical field of WEB development and application, in particular to a web version type method for freely switching computer cameras. The method comprises the steps that 1, a required label is defined in a page; 2, information of available multimedia input and output equipment on a computer is collected; 3, information of the computer cameras is added into an option; 4, parameters and methods (callVideo) for calling the cameras are defined; 5, media information is obtained again when the option of the computer cameras is changed, and the cameras are called. According to the method, the problem that users need to close operations of redundant computer cameras by themselves under the condition that a computer is provided with multiple cameras is solved, the workefficiency is improved, and the web version type method which is convenient to use, efficient and friendlier to the users and used for freely switching the computer cameras is provided for clients.

Description

technical field [0001] The invention relates to the technical field of WEB development and application, in particular to a method for freely switching computer cameras on a web page.
