特地有去看了下内核配置
Video For Linux
---help---
This kernel includes support for the new Video for Linux Two API,
(V4L2) as well as the original system. Drivers and applications
need to be rewritten to use V4L2, but drivers for popular cards
and applications for most video capture functions already exist.
内核默认配置好像就选择了ov511和SPCA5XX
这个版本的内核,中星微的好像就是用的SPCA5XX驱动
不过驱动是否用v4l2写的我就不知道了
楼主如果熟悉v4l2可否交流下
