      您好，结合您邮件中提到的现象和问题。
      我有几个建议可供分别尝试，

      1. 把你的控制流程改为
        开启--->循环读取达到需要的图片数目-->关闭。
      2. 如果不能按照第一条进行，在关闭摄像头到下次开启摄像头中间放一个delay，给足camera响应的时间。

      Questions will be answered as soon as possible, please be patient.
      如果你使用中文，请直接用中文提问。
      May the force be with YOU. (This is the translation of the mysterious Chinese symbol above.)

        @veye_xumm 因為我的主機電源是電池，為了節電，在影像採集完畢後會讓系統進入休眠狀態。所以我採取了開啟->讀取->關閉這樣的循環程序。目前的時序是 （開啟-讀取-關閉）6sec ->（休眠）54sec ，每 60 秒一個循環。
        昨天使用 C920 相同環境與軟體測試時（不休眠），執行了 32000 個循環沒有問題。然 CS-USB-IMX307 大約 4500 個循環就會產生 usb disconnect 的現象。
        原本我採用 MJPG 串流通到，昨天改變為 h264 串流通道測試仍舊在 6000+ 循環時發生。
        若需要一個 delay ，請問建議需要多久？

          @veye_xumm 我採用了另一個方式測試

          #!/bin/bash
          for ((i=0; i<65535; i++))
          do
          echo $i
          ffmpeg -nostats -loglevel error -y -ss 1 -input_format h264 -s 1280x720 -i /dev/video0 -qscale:v 4 -vframes:v 1 x_$i.jpg
          done

          過程之中，發現偶而會發生 usb disconnect，但試過幾秒鐘以後 /dev/video0 會恢復，/var/log/syslog 供你參考如下。

            请问，你的关闭，会把jetson nano 和 usb摄像头都断电吗？

            Questions will be answered as soon as possible, please be patient.
            如果你使用中文，请直接用中文提问。

              @veye_xumm jetson nano 使用 systemctl suspend 到休眠狀態，USB 不斷電。

                        以下是一段 python 程式碼，「開啟」「讀取」「關閉」的程序，cap.releaes() 之後，系統休眠約 54 sec，然後回到 cv2.VideoCapture() 重複一直執行。因為 cv2.VideoCapture() 啟動之後，每秒 30 張影像會一直放進 buffer 中，不讀取會一直佔住。所以為了讀取最新的影像，我會先用 cap.release() 先關閉 video capture。

        # 啟用一個影像擷取
        cap = cv2.VideoCapture(self.CAM_PORT, cv2.CAP_V4L)
        cap.set(cv2.CAP_PROP_FOURCC, cv2.VideoWriter.fourcc('h','2','6','4'))
        cap.set(cv2.CAP_PROP_FRAME_WIDTH, 1920)
        cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 1080)
        cap.set(cv2.CAP_PROP_FPS, 30)

        # 丟棄前面讀到的過亮的影像
        for i in range(self.DISCARD_NUM):
            ret, frame = cap.read()

        # 讀取正常影像
        ret, frame = cap.read()

        # 儲存影像檔
        cv2.imwrite(save_to, resized_frame, self.TARGET_JPEG_QUALITY)

        # 關閉影像擷取
        cap.release()

                  我现在基本的判断,是摄像头这端内存资源管理的问题,类似于内存泄漏. 我已经安排排查此问题,需要一定的时间.

                      希望有改版時，對於 uvcvideo 的參數也能夠支援。目前我無法對 power_line_frequency 做設定，對於不支援這些參數這點我非常困擾。以下是對 CS-USB-IMX307 (/dev/video0) 以及另一款 USB Camera module (/dev/video1) 的比較

                        这个问题，可能是v4l2-ctl在一个一个查询参数配置的时候，遇到不支持的参数之后就停掉了。实际摄像头是支持power_line_frequency 的，要不然我们用pc的软件也会显示不支持。
                        当然怎样通过命令行去配置，我现在只能想到C语言调用v4l2接口一途。

                          @veye_xumm 一般是可以這樣設定
                          v4l2-ctl -d /dev/video1 --set-ctrl=power_line_frequency=2
                          不會報錯誤訊息

                          但我對 CS-USB-IMX307 設定時，回應是
                          v4l2-ctl -d /dev/video0 --set-ctrl=power_line_frequency=2
                          unknown control 'power_line_frequency'

                          對了，我去下載你說那個 potplayer 但畫面長不一樣，是不是版本不同？我找不到設定的地方....

                            可以参考一下这篇文章：
                            http://wiki.veye.cc/index.php/Windows系统下怎样查看USB摄像头视频

                            另外，我这边对opencv和python不太熟。使用你给的ffmpeg的方法，的确重现了一次问题。
                            现在我的结论是，并不是内存泄漏，需要进一步查找，困难度比预期的要高。
                            有没有更快重现问题的方法？

                              我用 ffmpeg 看到的錯誤訊息跟 python3+opencv 跑出來的有點不太一樣。但都需要跑很久（每次都大概需要 2~3hrs 左右）可以重現。（本來每分鐘跑一個循環需要 2 天半）。如果我給你 python3 的程式碼，你那邊能夠執行嗎？（需要有 opencv 安裝好）

                                我今天安装了一个3.2.0版本的opencv，跑你之前给的例程不行。
                                安装4.5.2的版本，失败了。

                                  我重寫一個 python3 程式給你。照理沒有一定要 4.5.2，但你可以試看看 https://qengineering.eu/install-opencv-4.5-on-jetson-nano.html
                                  我是照這個步驟編譯的。編譯過程一定要把 swap 打開，不然虛擬記憶體會不夠用。

                                    我也是按照这个步骤做的。但是cmake阶段报错了。😰

                                      @veye_xumm cmake 可能需要重新安裝新版。
                                      參考這個（我有點忘記更新 cmake 的程序了)

                                        重新把程式碼排版ㄧ下...

                                        #! /usr/bin/python3
import cv2

def run_once():

    cap = cv2.VideoCapture('/dev/video0', cv2.CAP_V4L)
    # cap.set(cv2.CAP_PROP_FOURCC, cv2.VideoWriter.fourcc('M','J','P','G'))
    cap.set(cv2.CAP_PROP_FOURCC, cv2.VideoWriter.fourcc('h','2','6','4'))
    cap.set(cv2.CAP_PROP_FRAME_WIDTH, 1920)
    cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 1080)
    cap.set(cv2.CAP_PROP_FPS, 30)

    # 讀取 10 個 frames
    for i in range(10):
        ret, frame = cap.read()

    cap.release()

def main():
    cap_count = 0
    while True:
        run_once()
        print('-- %d --' % cap_count)
        cap_count += 1

if __name__ == '__main__':
    main()

                                          请问你的cmake版本是？
                                          我的是3.10.2

                                            我更新了一下cmake，还是编译不过。
                                            anyway，这事先放一放。
                                            我现在改了一个版本的固件，用ffmpeg循环测试的方法，测试到6000+次数，还是稳定的。
                                            请你也升级并老化测试一下：
