忘不吝赐教!
ubuntu12.04-i386
cheese3.4.1
运行cheese后无画面,只有黑色框
终端运行cheese后出现如下提示:

运行链接了clutter库的程序出现这个警告的解决办法
Clutter-WARNING **: Whoever translated default:LTR did so wrongly.

设置一个环境变量CLUTTER_TEXT_DIRECTION=ltr就可以了

谢谢你,我试了一下,声明后,警告消失了,但是图像采集依然有问题,怀疑是解码或者是驱动的问题。另外我在14.04 用opencv2.4.9打开摄像头,出现相同的问题。总之,十分感谢。
