mjpg-streamer is a command line application that can copy JPEG frames from one or more input plugins to multiple output plugins.
It can be used to stream JPEG files from webcams to various types of viewers, such as Chrome, Firefox, Cambozola, VLC, mplayer, and other software capable of receiving MJPG streams through an IP-based network.
It was originally written for embedded devices with very limited RAM and CPU resources. Its predecessor "uvc_streamer" was created because a Linux-UVC compatible camera directly generates JPEG data, even from an embedded device running OpenWRT, it can also achieve fast, high-performance M-JPEG streaming. The input module "input_uvc.so" captures such JPG frames from the connected webcam. mjpg-streamer now supports many different input devices.
