Pogoplug archlinux 安裝webcam

樓主 / firefox

老大曾經寫過一篇文章是介紹在pogplug上裝webcam，不過那是在dabian上，我的沒有裝dabian，只有archlinux，下面的教程就是針對於archlinux下的攝像頭安裝。

攝像頭:logitech c220，archlinux自帶驅動，所以免去了再安裝驅動的煩惱。

1.安裝攝像頭和軟件。
1.1 啟動archlinux,我直接root.
#>lsusb
Bus 001 Device 003: ID 046d:0819 Logitech, Inc. Webcam C210
#>dmesg
[ 21.676007] Linux video capture interface: v2.00
[ 21.706879] uvcvideo: Found UVC 1.00 device <unnamed> (046d:0819)
[ 21.758583] input: UVC Camera (046d:0819) as /devices/platform/orion-ehci.0/usb1/1-1/1-1.3/1-1.3:1.0/input/input
[ 21.758907] USB Video Class driver (1.1.1)

1.2. 安裝 mjpg-streamer
之前最好update system by (pacman -Syu)
#>pacman -S mjpg-streamer
#>mjpg_streamer -i "input_uvc.so -y" -o "output_http.so -p 8090 -w /usr/share/mjpeg-streamer/www"

然後在browser裡輸入:http://<ip>:8090
選擇stream option，就可以看到圖像了。

1.3.設置成服務
create a new file:
#>vi /etc/systemd/system/mjpgstream.service
[Unit]
Description=mjpg streamer

[Service]
ExecStart=/usr/local/appscript/mjpg.sh

[Install]
WantedBy=multi-user.target

create run script
#> vi /usr/local/appscript/mjpg.sh
#!/bin/sh
export LD_LIBRARY_PATH=/usr/lib/input_uvc.so
mjpg_streamer -i "input_uvc.so -y" -o "output_http.so -p 8090 -w /usr/share/mjpeg-streamer/www"

#> chmod a+x /usr/local/appscript/mjpg.sh
#> systemctl enable mjpgstream
#> systemctl start mjpgstream
