基於mini2440的WEB遠程視頻實時監控系統
2014年3月2號
1 本項目是基於申嵌實踐項目中的一個
由於官方提供的(光盤)編譯之後的代碼有問題，在這花費了不少的時間，再次寫這篇博客，希望大家在以後的學習中少走彎路，
參考：http://blog.csdn.net/opencpu/article/details/7016904
2 開發環境;
編譯器版本 :4.3.2
ubuntu 12.04
攝像頭中星微Z301p（YUYV） 和 Pixarrt() （這個免驅動的，因爲內核2.6以後已經包含了功能驅動，選中相應的模塊編進內核即可）
3 第一需要首先確定攝像頭可以被正常的識別到
顯示信息：
[root@FriendlyARM /]# usb 1-1: USB disconnect, address 2
usb 1-1: new full speed USB device using s3c2410-ohci and address 3
usb 1-1: New USB device found, idVendor=093a, idProduct=2700

中星微攝像頭正常識別
4 測試 Pixarrt() 攝像頭
運行./start_uvc.sh
