      @veye_xumm 您好,我现在在5.10的内核中可以正确发现MV-IMX265了。目前遇到两个问题
      1.是发送《v4l2-ctl -L》
      回复如下图,不回复FPS等信息了

      2.是发送《v4l2-ctl --set-ctrl frame_rate=10》设置帧率是会报错

      请您指点一下

        配参数应该配置到/dev/v4l-subdev2 吧?
        你可以参考参考part7.2

            我们wiki上面提到一个python脚本,可以做预览,你可以参考一下。

              @veye_xumm 暂时没有python环境,我尝试使用gstreamer里的脚本预览
              设置成这样:media-ctl -d /dev/media0 --set-v4l2 '"m00_b_mvcam 2-003b":0[fmt:Y8_1X8/2048x1544@1/30]'
              然后再预览:gst-launch-1.0 v4l2src device=/dev/video1 io-mode=4 ! queue ! video/x-raw,format=NV12,width=2048,height=1544,framerate=30/1 ! glimagesink
              出来的图颜色不对,有时绿有时粉,方向也不时我想要的,该如何旋转。

              如果设置成这样:media-ctl -d /dev/media0 --set-v4l2 '"m00_b_mvcam 2-003b":0[fmt:UYVY8_2X8/2048x1544@1/30]'
              然后再预览:gst-launch-1.0 v4l2src device=/dev/video1 io-mode=4 ! queue ! video/x-raw,format=NV12,width=2048,height=1544,framerate=30/1 ! glimagesink
              不出图。

              麻烦您指导一下,我的模块是MV-IMX265

                对于只支持单色RAW8格式的camera,直接通过gstreamer进行预览,我们现在觉得支持度不够。
                建议你还是用python调用一下opencv跑一下,这个是最简单的。

                      @veye_xumm 用C++调用OPENCV也可以预览到正常的图像把。

                        应该没问题的。 不过我们缺乏应用层尤其是opencv的经验。 我理解是python调用opencv能预览,用c++应该就可以。
                        opencv的主要问题是效率问题,数据导入到opencv的时候需要用cpu跑一次数据格式转换。

                          @veye_xumm 我用《v4l2dev_2_opencv_show_grey.py》这个文件,报错camera open failed.

                            是参考我们在rk平台的这个python程序吗? 能否截图看一下具体错误?
                            /dev/video0是否存在?

                              @veye_xumm /dev/video0确认存在的,用的下面这个PY脚本

                              import sys
                              import argparse

                                  v4l2_cmd = f'media-ctl -d /dev/media0 --set-v4l2 \'"m00_b_mvcam 2-003b":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:

                                          cv2.imshow('demo',img)
                                          cv2.waitKey(1)
                                  else:

                                  cv2.destroyAllWindows()
                              if __name__ == '__main__':
                                  parser = argparse.ArgumentParser(description='Read camera video stream')
                                  parser.add_argument('--width', type=int, default=1080, help='width of the video stream')
                                  parser.add_argument('--height', type=int, default=1080, 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=7, help='i2c bus number')
                                  args = parser.parse_args()
                              
                                  read_cam(args.width, args.height, args.fps, args.i2c)
                              

                              报错如下
