fimc_capture_scaler_info: invalid source size(sx : -806203264, sy : -815800792)

平台： s5pc110

系统： android2.3

摄像头：bf3703、s5k5ba、gc0308、gt2005

1、在andorid2.2系统上调试好的摄像头驱动，移植到android2.3过程中有以下错误：

[36.338839] bf3703_enum_framesizes

[36.341381] bf3703_s_ctrl

[36.343985] xu_bin sx= -806203264,sy = -815800792,tx= 640,ty= 480

[36.350045] s3c-fimc-0 :fimc_capture_scaler_info: invalid source size(sx : -806203264, sy : -815800792)

报错位置：driver\media\video\samsung\fimc\fimc_capture.c中

static int fimc_capture_scaler_info(struct fimc_control *ctrl)

{

struct fimc_scaler *sc = &ctrl->sc;

struct v4l2_rect *window = &ctrl->cam->window;

int tx, ty, sx, sy;

sx = window->width;

sy = window->height;

tx = ctrl->cap->fmt.width;

ty = ctrl->cap->fmt.height;

sc->real_width = sx;

sc->real_height = sy;

printk("xu_bin sx= %d,sy = %d,tx= %d,ty= %d\n",sx,sy,tx,ty);

fimc_dbg("%s: CamOut (%d, %d), TargetOut (%d, %d)\n", \

__func__, sx, sy, tx, ty);

if (sx <= 0 || sy <= 0) {

fimc_err("%s: invalid source size(sx : %d, sy : %d)\n",

__func__, sx, sy);

return -EINVAL;

}

2，在android2.3的内核中要加入下面红色部分：

static int GT2005_enum_framesizes(struct v4l2_subdev *sd, \

struct v4l2_frmsizeenum *fsize)

{

int err = 0;

#if 1//modify by xu_bin for GB

fsize->type = V4L2_FRMSIZE_TYPE_DISCRETE;

fsize->discrete.width = 640;

fsize->discrete.height = 480;

#endif

return err;

}
