楼主
大家好,我需要让系统支持一个定制的mipi摄像头,它支持1280x720和1027x768这两种分辨率,然后我直接使用了系统自带的OV2685_MIPI_YUV的代码,修改了里面的一些通信,然后成功的让系统能够播放1280x720的分辨率,但是呢我设置1027x768这个分辨率的时候发现不行,系统本身好像不支持这个分辨率,然后我在cam_board.xml 以及 CameraHal 里面设置了 相关的分辨率,这样上层是可以设置这个分辨率的,但是我发现,出了一个问题:

- 剩下是一直重复打印上面的两句话
复制代码 其中这里有句 01-01 15:40:36.896: E/CameraHal_Marvin(166): CAM_API_CAMENGINE: changeResolution (can't change resolution of sensor)
这里是libisp_silicomimageisp_api这个库里面的函数 , 不知道调用了什么,导致设置失败了,接着分辨率就变成了默认的1280x720了:
01-01 15:40:36.896: E/CameraHal(166): setupPreview(259): >>>>>>>width_sensor=1280,height_sensor=720,preview_w=1280,preview_h=720
有没有知道这里该怎么改才能让系统支持1027x768这个分辨率呢?
CAM_API_CAMENGINE: changeResolution (can't change resolution of sensor)
这里该如何修改才能够正常的设置呢?一定得是系统自带的分辨率么?kernel 驱动里面好像也没有找到有关分辨率设置的相关代码,都是在cam_board.xml里面设置的么?
我看好久以前有人发过帖子
http://developer.t-firefly.com/f ... =%C9%E3%CF%F1%CD%B7
这个人也是添加新分辨率遇到了问题,有人能解决这个问题么?
