        我是这么写的,我的I2C用的I2C2,产品分辨率2048*1544

        import sys
        import argparse
        import subprocess
        import cv2
        
        def read_cam(width, height, fps,i2c):
            
            v4l2_cmd = f'media-ctl -d /dev/media0 --set-v4l2 \'"m00_b_mvcam {i2c}-003b":0[fmt:Y8_1X8/{width}x{height}@1/{fps} field:none]\''
            subprocess.run(v4l2_cmd, shell=True)
            
            cap = cv2.VideoCapture(f"v4l2src io-mode=dmabuf device=/dev/video0 ! video/x-raw, format=(string)GRAY8, width=(int){width}, height=(int){height} ! appsink")
            if cap.isOpened():
                cv2.namedWindow("demo", cv2.WINDOW_AUTOSIZE)
                while True:
                    ret_val, img = cap.read();
                    cv2.imshow('demo',img)
                    cv2.waitKey(1)
            else:
             print ("camera open failed");
            cv2.destroyAllWindows()
        if __name__ == '__main__':
            parser = argparse.ArgumentParser(description='Read camera video stream')
            parser.add_argument('--width', type=int, default=2048, help='width of the video stream')
            parser.add_argument('--height', type=int, default=1544, help='height of the video stream')
            parser.add_argument('--fps', type=int, default=30, help='fps of the video stream')
            parser.add_argument('--i2c', type=int, default=2, help='i2c bus number')
            args = parser.parse_args()
            read_cam(args.width, args.height, args.fps, args.i2c)

          @w88121446 不好意思我没有说清楚,我的意思是,你调用这个脚本的时候,使用的命令行是什么?参数是什么?

              需要给一下必要的参数

              python3 ./v4l2dev_2_opencv_show_grey.py --width 2048 --height 1544 --fps 45 --i2c 2

                @veye_xumm 我使用您发给我的命令还是不能打开caramer,再次确认了是I2C-2没有错

                  图像可以采集出来了,想实时预览的话有什么办法吗?

                  此时你说的图像可以采集出来,是怎么判断的?

                    @veye_xumm 可以使用下面这个命令拍照,图片正常

                    ./yavta -c1 -Fy81-2048x1544.raw --skip 0 -f Y8 -s 2048x1544 /dev/video0

                      如果是这样,驱动层是没有问题的。
                      怀疑是使用 OpenCV 的 GStreamer 管道时,确保正确安装和配置了 GStreamer:
                      在某些系统上,GStreamer 可能没有正确配置,导致 OpenCV 无法通过 GStreamer 打开视频设备。

                      gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=GRAY8,width=2048,height=1544 ! autovideosink

                        用您发的这个命令的话,我要把format=GRAY8改成format=NV12才能预览。

                        关于GStreamer 可能没有正确配置,导致 OpenCV 无法通过 GStreamer 打开视频设备。这个事情,我就查一查GStreamer的配置问题是吧!

                          @w88121446 我们用的firefly的板子,gstreamer是支持gray8数据格式的。
