The client APIs on mobile devices and desktops are not initially synchronized. Initially, you always have some features and APIs on your mobile device, but slowly, these APIs appear on your desktop computer. One of the application interface technologies is the Getusermedia API, which allows app developers to access the user's webcam or built-in camera. Let me show you how to access your webcam through a bro

Push-Flow is a third-party iflivekit framework. This framework is based on RTMP protocol, the C language and OC language is very clear, very friendly to OC language, relatively simple to use.The gpuiimage is integrated inside the Iflivekit. The interior achieves such glamorous effects as image rendering. Reduces the development time of the glamorous effect of debugging.Requirements: Create a simple push-flow page. Included features are: 1. Push-flow status monitoring. 2. Switch the camera. 3. To

How to Use Motion to manipulate Linux surveillance cameras Motionhttp: // www. lavrsen. dk/foswiki/bin/view/Motion/) is a small, lightweight, but powerful application software that can be used to manipulate surveillance cameras on Linux. It works with any camera that supports Linux, including all V4L network cameras, many IP cameras, and anxun Axis cameras. It also controls the translation and tilt functions. Motion allows you to record short clips and snapshots in JPEG, PPM, and MPEG formats.
