V853使用MIPI CSI接口是否只支持RAW格式像素？
-
因为给的V853 sensor支持列表全都是raw格式的摄像头，我再在/tina-v853-open/lichee/linux-4.9/drivers/media/platform/sunxi-vin/modules/sensor文件夹下搜索mipi_bps，因为mipi摄像头肯定要设置这个参数，结果只找到rn6854和nvp名称开头的驱动是使用YUV像素的，但这些传感器在kernel_menuconfig里都不能选中。
我再仔细看了看教程，用到的名词是"YUV 的并口模组"，用的是例子是OV5640，它的驱动里没有设置mipi_bps，所以，，是我误解了？V853的MIPI CSI不能接收YUV格式像素？ -
@xjy_5 MIPI CSI接收的是RAW数据，不支持YUV这样的
-
@awwwwa 难怪这么久都没有成，一开始就错了，呜呜呜...
现在又有了另一个问题，TC358743里有另一个模式使用的是MEDIA_BUS_FMT_RGB888_1X24，这个V853支持吗？现在我找了半天大概也是不支持 -
@xjy_5 RGB888_1X24 我感觉是直出RGB信号的吧
这个DTSI是在T507上配置的，可以参考一下

重新确认了一下，MIPI 接受的数据格式与MIPI无关，也就是MIPI也可以接收YUV这类数据。
是否是因为后端配置的问题。参考T507的TC358743驱动配置的是
MEDIA_BUS_FMT_UYVY8_2X8 -
@awwwwa 应该后端设置出问题了，开了VIN_LOG_FMT，能看到这些内容

@awwwwa 是不是要改ISP驱动啊？还是说应用层调用的时候有什么办法不使用ISP?
-
@xjy_5 驱动都不用ISP，ISP是上层用户程序定义的，可以用camerademo抓图测试绕过ISP

Sensor输出图像格式
sensor输出图像格式定义在sensor_format_struct结构体中，vin v4l2驱动框架通过获取sensor_format_struct结构体成员信息来获取当前sensor输出图像格式，sensor_formats结构体中需要填写的成员是.desc和.mbus_code。
.desc是描述sensor输出的图像格式，本例中gc2053是RGB Raw sensor，故.desc成员填写为"Raw RGB Bayer"。.mbus_code为sensor图像数据输出顺序，sensor RAW图像是以Bayer格式传输的（每个像素只表示RGB其中一个分量），常见的Bayer格式为：RGGB、BGGR、GRBG、GBRG，这个可以询问一下sensor原厂或者翻阅sensor datasheet进行查找。.mbus_code若填错, 会导致色彩偏紫红和出现网格状纹理。 本例中
gc2053图像输出格式为RGGB，且当前的配置是10bit mipi接口，故.mbus_code填写为
MEDIA_BUS_FMT_SRGGB10_1X10，若当前调试的sensor配置是8bit输出，
则.mbus_code填写为MEDIA_BUS_FMT_SRGGB8_1X8，按照这种规则进行填写。static struct sensor_format_struct sensor_formats[] = { { .desc = "Raw RGB Bayer", /* 填写 Sensor 初始化时默认的 Bayer 格式，目的是告知主控端ISP当前图像的 Bayer 格式，ISP需要以同样的格式来接收和处理图像数据 */ .mbus_code = MEDIA_BUS_FMT_SRGGB10_1X10, .regs = sensor_fmt_raw, .regs_size = ARRAY_SIZE(sensor_fmt_raw), .bpp = 1 }, }; 如果
sensor输出图像格式是YUV的话，则需要根据sensor图像数据输出顺序选择YUYV/VYUY/UYVY/YVYU其中一种，如下：static struct sensor_format_struct sensor_formats[] = { { .desc = "YUYV 4:2:2", .mbus_code = MEDIA_BUS_FMT_YUYV8_2X8, .regs = sensor_fmt_raw, .regs_size = ARRAY_SIZE(sensor_fmt_raw), .bpp = 2, }, }; 同时，
sensor_get_fmt_mbus_core函数也要将当前sensor的图像输出格式赋值给函数参数*code，有些sensor在翻转后RGB顺序不会自动进行调整，需要主控端ISP需要按照当前sensor翻转后的图像格式更新RGB顺序，避免翻转后出现图像色彩异常的问题，如下，gc2053支持翻转后sensor内部自动调整RGB顺序，所以函数参数*code仍赋值为MEDIA_BUS_FMT_SRGGB10_1X10。static int sensor_get_fmt_mbus_core(struct v4l2_subdev *sd, int *code) { *code = MEDIA_BUS_FMT_SRGGB10_1X10; // gc2053 support change the rgb format by itself } static long sensor_ioctl(struct v4l2_subdev *sd, unsigned int cmd, void *arg) { int ret = 0; struct sensor_info *info = to_state(sd); switch (cmd) { case VIDIOC_VIN_GET_SENSOR_CODE: /* vin v4l2框架层在sensor翻转接口被调用后， 通过VIDIOC_VIN_GET_SENSOR_CODE获取当前sensor的RGB顺序 */ sensor_get_fmt_mbus_core(sd, (int *)arg); break; default: return -EINVAL; } return ret; } -

@awwwwa reset脚，中断脚我在设备树其他地方定义，在驱动的sensor_init里获取来用了，也能用，iic是用rk628原本的regmap，也能用，不过这些放一边先。
驱动里设置 MEDIA_BUS_FMT_UYVY8_2X8 用camerademo抓图应该设置那个像素格式？使用gc2053的经验告诉我，设备树里关掉isp后抓图设置的像素格式应该和驱动里设置的一致，那MEDIA_BUS_FMT_UYVY8_2X8 对应的是哪个？int return_format(char *short_name) { if (strcmp(short_name, "YUV422P") == 0) return V4L2_PIX_FMT_YUV422P; else if (strcmp(short_name, "YUV420") == 0) return V4L2_PIX_FMT_YUV420; else if (strcmp(short_name, "YVU420") == 0) return V4L2_PIX_FMT_YVU420; else if (strcmp(short_name, "NV16") == 0) return V4L2_PIX_FMT_NV16; else if (strcmp(short_name, "NV12") == 0) return V4L2_PIX_FMT_NV12; else if (strcmp(short_name, "NV61") == 0) return V4L2_PIX_FMT_NV61; else if (strcmp(short_name, "NV21") == 0) return V4L2_PIX_FMT_NV21; else if (strcmp(short_name, "YUYV") == 0) return V4L2_PIX_FMT_YUYV; else if (strcmp(short_name, "YVYU") == 0) return V4L2_PIX_FMT_YVYU; else if (strcmp(short_name, "UYVY") == 0) return V4L2_PIX_FMT_UYVY; else if (strcmp(short_name, "VYUY") == 0) return V4L2_PIX_FMT_VYUY; else if (strcmp(short_name, "MJPEG") == 0) return V4L2_PIX_FMT_MJPEG; else if (strcmp(short_name, "H264") == 0) return V4L2_PIX_FMT_H264; else if (strcmp(short_name, "BGGR8") == 0) return V4L2_PIX_FMT_SBGGR8; else if (strcmp(short_name, "GBRG8") == 0) return V4L2_PIX_FMT_SGBRG8; else if (strcmp(short_name, "GRBG8") == 0) return V4L2_PIX_FMT_SGRBG8; else if (strcmp(short_name, "RGGB8") == 0) return V4L2_PIX_FMT_SRGGB8; else if (strcmp(short_name, "BGGR10") == 0) return V4L2_PIX_FMT_SBGGR10; else if (strcmp(short_name, "GBRG10") == 0) return V4L2_PIX_FMT_SGBRG10; else if (strcmp(short_name, "GRBG10") == 0) return V4L2_PIX_FMT_SGRBG10; else if (strcmp(short_name, "RGGB10") == 0) return V4L2_PIX_FMT_SRGGB10; else if (strcmp(short_name, "BGGR12") == 0) return V4L2_PIX_FMT_SBGGR12; else if (strcmp(short_name, "GBRG12") == 0) return V4L2_PIX_FMT_SGBRG12; else if (strcmp(short_name, "GRBG12") == 0) return V4L2_PIX_FMT_SGRBG12; else if (strcmp(short_name, "RGGB12") == 0) return V4L2_PIX_FMT_SRGGB12; else return -1; } -
@awwwwa 要是有办法绕掉sunxi_isp.c就好了
，sunxi_csi_formats里都有MEDIA_BUS_FMT_UYVY8_2X8的定义了
-
@xjy_5 一般来说配置sensor0_isp_used = <0>; 就不会调用ISP，虽然会配置但是不会处理。需要再跟踪一下调用
-
@awwwwa 出图了，黑白色，我的天，今晚做梦都能笑出来了，哈哈
主要改了sunxi_isp_formats 和 sunxi_tdm_formats ，添加了含MEDIA_BUS_FMT_UYVY8_2X8的定义static struct tdm_format sunxi_tdm_formats[] = { { .code = MEDIA_BUS_FMT_UYVY8_2X8, .input_type = INPUTTPYE_8BIT, .input_bit_width = RAW_8BIT, .raw_fmt = BAYER_RGGB, },{ ...static struct isp_pix_fmt sunxi_isp_formats[] = { { .fourcc = V4L2_PIX_FMT_YUV422P, .mbus_code = MEDIA_BUS_FMT_UYVY8_2X8, .infmt = ISP_BGGR, .input_bit = RAW_8, },{ ...用yuvplayer看的图
-
@awwwwa 能看到有点彩色，但和图像有偏移
-
@awwwwa 果然这邪门方法还是不想，出图了，黑白色搞不定，除非继续深挖改写代码，这样这块只会变得越来越像屎山，有没有什么靠谱的办法啊。
-
@awwwwa 看来设备树里关ISP只是不使用硬件ISP但set_fmt还是会在代码里面过过，我开了ISP就出现isp error了，现在看来抓图应该是抓成功了，但数据格式不太对，有颜色，颜色都有偏移，文件大小也稍大了些，理论上192010802=417200字节，实际上是4177920字节，多出来什么了？
我截图桌面用ffmpeg转成yuv422图片确实是417200字节
-
@xjy_5 这个不太清楚了，没有调试过这款芯片。我这边是T507+TC358743实现的
-
@awwwwa 我这边想走硬件获取视频输入好适配H264编码，像素格式YUV422P，默认mpp的程序里是不支持这个格式的，原来的就只有YUV420，请问有哪个设备的SDK适配了YUV422P像素格式的摄像头吗？我参考参考程序
在videoInputHW.c里有
-
@xjy_5 请问最后有成功支持TC358743吗？
