      您好:我參考這個網址http://wiki.veye.cc/index.php/Mv_series_camera_appnotes_4_rpi/zh#.E8.A7.A6.E5.8F.91.E6.A8.A1.E5.BC.8F
      安裝veye_mvcam驅動成功,也抓得到/dev/video0,但是卻無法在opencv及VLC上讀取這個camera,VLC我是參考http://wiki.veye.cc/index.php/V4L2_mode_for_Raspberry_Pi的第6點

      S__393265156.jpg

      請問有方法解決嗎?謝謝!

          @veye_xumm 您好:我參考網頁的6.6.5.2使用opencv預覽GRAY格式圖片,python ./v4l2dev_2_opencv_show_grey.py --width 640 --height 480 --fps 30
          測試是可以有畫面的,但請問width及height是不是不能做調整,我試著調整為2064 * 1544或1920*1080都會顯示Failed to open video device,請問有方法能調整解析度嗎?
          謝謝您!

              这个问题的原因是我们为了实现roi功能,采用selection作为驱动接口。而实际上这个接口过于生僻,应用层如opencv的cv2支持的不好。
              现在给你提供一个临时可用的脚本,后续我们会修改掉驱动的实现方式。

              import sys
              import argparse
              import subprocess
              import cv2
              
              def read_cam(width, height, fps):
                  
                  v4l2_cmd = f"v4l2-ctl --set-selection=target=crop,top=0,left=0,width={width},height={height}"
                  subprocess.run(v4l2_cmd, shell=True)
                  
                  v4l2_cmd = f"v4l2-ctl --set-ctrl frame_rate={fps}"
                  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=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')
                  args = parser.parse_args()
              
                  read_cam(args.width, args.height, args.fps)

                @veye_xumm 我们的驱动已经更新,原有方法依旧有效。请参考。

                  我重新下載此網站6.1的驅動包,並依照6.3卸載驅動後用6.2重新安裝驅動。
                  在此網站下載v4l2dev_2_opencv_show_grey.py及v4l2dev_2_opencv_show_grey2.py,只有v4l2dev_2_opencv_show_grey2.py(原本的)可以使用,後來的v4l2dev_2_opencv_show_grey.py會顯示S__396476419.jpg

                  錯誤內容為:
                  [ WARN:0@0.404] global /home/pi/opencv/modules/videoio/src/cap_gstreamer.cpp (2401) handleMessage OpenCV | GStreamer warning: Embedded video playback halted; module v4l2src0 reported: Device '/dev/video0' does not support 1:4:7:1 colorimetry

                  camera open failed

                  請問我是哪裡做錯了嗎?
                  謝謝您!

                      不好意思,我照著這網頁嘗試過編譯,但始終無法編譯成功,卡在1.7.1缺少構建目錄,也嘗試使用解決方案:
                      升級piOS,重新構建。
                      sudo apt install raspberrypi-kernel raspberrypi-kernel-headers
                      安裝特定版本的內核頭文件。
                      raspberrypi-bootloader 版本為1.20230405-1
                      raspberrypi-kernel版本為1.20230405-1
                      目前raspberrypi的版本Linux raspberrypi 6.1.21-v8+

                      可以幫助我嗎?謝謝!

                          我重新灌樹梅派他剛開始是這樣S__396902407.jpg
                          然後讓他自己更新
                          S__396902409.jpg S__396902410.jpg
                          最後升級後變成這樣

                                到这个链接
                                https://archive.raspberrypi.org/debian/pool/main/r/raspberrypi-firmware/?C=M;O=D
                                下载这个文件:
                                raspberrypi-kernel-headers_1.20230405-1_arm64.deb
                                然后手动安装一下,应该就有build文件了。试一下。

                                          升级系统出错的问题,我觉得是树莓派组织sudo apt install raspberrypi-kernel 这个包管理的不好。 回头可以还是推荐客户用sudo apt full-upgrade吧。

                                          这个问题放一边,先不管他。
                                          你这个如果系统是32位的

                                          1. 先看看/lib/modules/6.1.21-v7l+下面有没有build。
                                          2. 如果有,改一下cam_drv_src\rpi-6.1.y\Makefile,手动指定一下KERNEL_ROOT
                                          KERNEL_ROOT=/lib/modules/6.1.21-v7l+/build 
                                          

                                          Questions will be answered as soon as possible, please be patient.

                                            使用sudo apt full-upgrade 也是無法使用
                                            改Makefile KERNEL_ROOT=/lib/modules/6.1.21-v7l+/build
                                            也有錯誤S__397066260.jpg

                                            我最後把系統改成64位元再照著上面的步驟重複一次就可以使用了
                                            真的非常感謝您!!
