"Requirement is called camera, scan the qr code, parsing qr code", is in the browser? As far as I know is to do, you see which websites, one east, a web page version of the treasure, can call camera sweep qr code? Unless special plug-in installation in the browser, only on the page (HTML + CSS + javascript) is made,If the server side, your intraweb program can be used dspack, videocap, component calls such VFW camera, but is the local camera, do you want to invoke the browser end computer cameras or not (or not serious security hidden danger? :),

Want to use on a mobile phone, idea is a mobile phone camera, browser callsCodePudding user response:

The browser can do, but to the plugin, you can use the VLC player plugin is embedded into the page to play the video stream of cameras (set the RTSP stream address line), capture the need to redo a plug-in, an additional to capture video player window screenshot uploaded to the server after identification, the video server results returned back, really want to do is probably to be a plug-in to capture video player window,
