樹莓派+UVC攝像頭+網路監控

電腦上觀看樹莓派的USB攝像頭影象
想在自家房間搭建個USB攝像頭。城中村還是比較亂的。路人吵吵吵。不信任那些人的德行，自好自行做好準備一套好 裝好拆的裝置。想看他們時候，可以立馬安裝裝置。
硬體上：樹莓派Zero W，USB攝像頭。路由器。膝上型電腦。
樹莓派上：
安裝mjpg-streamer:
sudo apt-get update sudo git clone https://github.com/jacksonliam/mjpg-streamer.git cd mjpg-streamer/mjpg-streamer-experimental sudo make sudo make install
使用mjpg-streamer還是會出現還多的error，需要配置引數。
mjpg_streamer -i "input_uvc.so -d /dev/video1 -r 640x480 -f 20 -yuv" -o "output_http.so -p 8082 -w /www/camwww"

github的repo中也說明了是experimental，出現了error還是正常使用的（這我不習慣……）。網頁上可以顯示影象。然後電腦的VLC播放器可以開啟視訊流。
硬體照：
樹莓派zero W + USB攝像頭 + FT232模組。
效果：
小結：2小時內搭建了監控系統。在筆記本上可以觀看攝像頭節點的視訊流。節點是基於樹莓派加mjpg-streamer。筆記本用VLC。資料3是呼叫了官方攝像頭，用軟排線的。資料4是伺服器加客戶端都是用VLC播放器。
據說VLC還有手機端……
