看，风轻云淡

刷了论坛上下载的固件：硬件版本V1.6及以上703N专用WIFI-Robot智能小车机器人 Openwrt固件http://www.wifi-robots.com/thread-6936-1-1.html     摄像头用的天敏r006，但是摄像头没有开启，看系统日志打印了这些消息：

是怎么回事呢？为什么初始化失败，是摄像头不支持吗？

init_VideoIn failed
1、你的摄像头可能不支持Mjepg
2、检查摄像头的5V供电够不够。

我看论坛上好像有人用过这个摄像头的，天敏r006，应该支持Mjpeg格式的，那怎么检查供电够不够啊？

是不是可以压缩视频格式的？具体怎么操作？

/etc/init.d/wificar文件中，Mjpg_streamer启动参数加一个-y
