Pixel Format is not same between capture and output

hi，
I am using a isp which output YUYV to tx2,when i using this command to capture video,only select UYVY pixel format can see right picture
1、capture command

v4l2-ctl -d /dev/video0  --stream-mmap --stream-count=10 --stream-to=image.yuv

2、query the video capture format

nvidia@tegra-ubuntu:~/Videos$ v4l2-ctl -V
Format Video Capture:
        Width/Height      : 1920/1080
        Pixel Format      : 'YUYV'
        Field             : None
        Bytes per Line    : 3840
        Size Image        : 4147200
        Colorspace        : JPEG
        Transfer Function : Default (maps to sRGB)
        YCbCr/HSV Encoding: Default (maps to ITU-R 601)
        Quantization      : Default (maps to Full Range)
        Flags             :
nvidia@tegra-ubuntu:~/Videos$

the code is follow:
1、

#define OV2718_DEFAULT_DATAFMT	MEDIA_BUS_FMT_UYVY8_2X8
common_data->colorfmt		= camera_common_find_datafmt(
					  OV2718_DEFAULT_DATAFMT);
..
priv->s_data			= common_data;
..
err = camera_common_initialize(common_data, "ov2718");

2、camera_sensor.c

static const struct camera_common_colorfmt camera_common_color_fmts[] = {
	{
		MEDIA_BUS_FMT_SRGGB12_1X12,
		V4L2_COLORSPACE_SRGB,
		V4L2_PIX_FMT_SRGGB12,
	},
	{
		MEDIA_BUS_FMT_SRGGB10_1X10,
		V4L2_COLORSPACE_SRGB,
		V4L2_PIX_FMT_SRGGB10,
	},
	{
		MEDIA_BUS_FMT_SBGGR10_1X10,
		V4L2_COLORSPACE_SRGB,
		V4L2_PIX_FMT_SBGGR10,
	},
	{
		MEDIA_BUS_FMT_SRGGB8_1X8,
		V4L2_COLORSPACE_SRGB,
		V4L2_PIX_FMT_SRGGB8,
	},
	{
		MEDIA_BUS_FMT_UYVY8_1X16,
		V4L2_COLORSPACE_SRGB,
		V4L2_PIX_FMT_UYVY,
	},
       {
		MEDIA_BUS_FMT_UYVY8_2X8,
		V4L2_COLORSPACE_SRGB,
		V4L2_PIX_FMT_UYVY,
	},
	{
		MEDIA_BUS_FMT_VYUY8_2X8,
		V4L2_COLORSPACE_SRGB,
		V4L2_PIX_FMT_VYUY,
	},
	{
		MEDIA_BUS_FMT_YUYV8_2X8,
		V4L2_COLORSPACE_SRGB,
		V4L2_PIX_FMT_YUYV,
	},
	{
		MEDIA_BUS_FMT_YVYU8_2X8,
		V4L2_COLORSPACE_SRGB,
		V4L2_PIX_FMT_YVYU,
	},

3、sensor_common.c,uyvy is set in device-tree

static int extract_pixel_format(
	const char *pixel_t, u32 *format)
{
	size_t size = strnlen(pixel_t, OF_MAX_STR_LEN);

	if (strncmp(pixel_t, "bayer_bggr10", size) == 0)
		*format = V4L2_PIX_FMT_SBGGR10;
	else if (strncmp(pixel_t, "bayer_rggb10", size) == 0)
		*format = V4L2_PIX_FMT_SRGGB10;
	else if (strncmp(pixel_t, "bayer_bggr12", size) == 0)
		*format = V4L2_PIX_FMT_SBGGR12;
	else if (strncmp(pixel_t, "bayer_rggb12", size) == 0)
		*format = V4L2_PIX_FMT_SRGGB12;
	else if (strncmp(pixel_t, "bayer_wdr_pwl_rggb12", size) == 0)
		*format = V4L2_PIX_FMT_SRGGB12;
	else if (strncmp(pixel_t, "bayer_wdr_dol_rggb10", size) == 0)
		*format = V4L2_PIX_FMT_SRGGB10;
	else if (strncmp(pixel_t, "bayer_xbggr10p", size) == 0)
		*format = V4L2_PIX_FMT_XBGGR10P;
	else if (strncmp(pixel_t, "bayer_xrggb10p", size) == 0)
		*format = V4L2_PIX_FMT_XRGGB10P;
	else if (strncmp(pixel_t, "uyvy", size) == 0)
	{
	 //	 *format = V4L2_PIX_FMT_YVYU;
       //        *format = V4L2_PIX_FMT_UYVY;
	 	*format = V4L2_PIX_FMT_YUYV;
	//	*format = V4L2_PIX_FMT_VYUY;
	}
	else {
		pr_err("%s: Need to extend format%s\n", __func__, pixel_t);
		return -EINVAL;
	}

	return 0;
}

Could you print the format from the vi4_fops.c to check if the value with TRM PIXFMT register.

vi4_channel_write(chan, vnc_id, PIXFMT_FORMAT, format);

1、I add code like this

static void vi4_channel_write(struct tegra_channel *chan,
		unsigned int index, unsigned int addr, u32 val)
{
        printk("%s,val=0x%0x\n",__func__,val);
	writel(val,
		chan->vi->iomem + VI4_CHANNEL_OFFSET * (index + 1) + addr);
}

2、when system is boot,i can got the log info,whit this command

dmesg |grep vi4_channel_write

3、when i capture video,the log is found,but the message is too much

v4l2-ctl -d /dev/video0  --stream-mmap --stream-count=10 --stream-to=ov2718_video.yuv

Just print the write function to write the PIXFMT_FORMAT in the tegra_channel_capture_setup()

hi,ShaneCCC
What is the offset value of the register,i modify the code and the log message is follow:

printk("%s,val=0x%0x,addr=0x%0x,index=%d,offset=0x%0x\n",__func__,val,addr,index,
                  VI4_CHANNEL_OFFSET * (index + 1) + addr);

the PIXFMT_FORMAT val = 200

Create Surface with imgW=1920, imgH=1080, memFmt=200

Why don’t you have print function in the tegra_channel_capture_setup() instead of vi4_channel_write()

The REG setting is correct, that show the host driver setting is fine. It’s could be the output source pixel type not as your expect.

200 = T_Y8_U8__Y8_V8

tks for your reply
I change the isp output format as UYVY,the problem is not found
