我的内核是2.6.15,插入摄像头后可以直接认出来,但是截取图像的时候出错.
v4l-conf的输出结果:
$ v4l-conf
v4l-conf: using X11 display :0.0
dga: version 2.0
WARNING: No DGA support available for this display.

xawtv运行后可以看到图像,但是无法截图
$ xawtv
This is xawtv-3.94, running on Linux/i686 (2.6.15-1-686)

v4l-conf had some trouble, trying to continue anyway
Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-*" to type FontStruct

请问应该怎么解决这个问题呢? |
