求助。最新版arch。摄像头已经驱动，cheese不正常

[zhexuezhuzi]

代码： 全选

 mplayer tv:// -tv driver=v4l2 

使用上述命令可以用mplayer看到摄像头正常工作。

但是使用cheese可以拍照，却不能在其窗口内预览，窗口里显示的永远是刚打开cheese时的图像。换句话说，正常情况下图像应该是可变的，但是现在图像是静止的。

求助。

是不是因为驱动？可是mplyer可以通过driver=v4l2播放流媒体。

难道cheese无法正确识别驱动？

v4l2的问题 同样的 skype能认到但是捕捉不到....

可靠消息说2.6.31的git12版本及以后就好了...

现在改用mplayer截屏热键来实现拍照功能。唉
