分析：

这问题是由于摄像头的实际帧率没在设置的帧率范围内造成的。

处理方法：

1、首先抓取log看一下实际帧率在什么范围内，抓取方法如下：

adb root

adb shell setprop persist.debug.sf.showfps 1

adb logcat > logfps.txt

然后再搜索关键字PROFILE_PREVIEW_FRAMES_PER_SECOND。

2、然后再根据实际的帧率修改sensor_out_info和default_fps_ranges的范围。

static cam_fps_range_t default_fps_ranges[] = {
{ 15.0, 15.0, 15.0, 15.0},
{ 24.0, 24.0, 24.0, 24.0},
{ 30.0, 30.0, 30.0, 30.0},
};

————在mct_pipeline.c里修改，前面两个参数是preview的min和max，后面两个参数是video的min和max。

static struct sensor_lib_out_info_t sensor_out_info[] = {

#if SNAPSHOT_PARAMS

{/* 30 fps full size settings */

.x_output = 3264,

.y_output = 2448,

.line_length_pclk = 3688,

.frame_length_lines = 2530,

.vt_pixel_clk = 280000000,

.op_pixel_clk = 280000000,

.binning_factor = 1,

.max_fps = 30.0,

.min_fps = 1,

.mode = SENSOR_DEFAULT_MODE,

},

#endif

————在xxx_lib.c里修改，这里主要修改max_fps和min_fps的值。
