SOLVED CS-USB-IMX307 OpenCV 連續採集影像造成 USB disconnct

[coolmitch]

@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。

[coolmitch]

@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....

[veye_xumm]

@coolmitch
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？

[coolmitch]

@veye_xumm
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）

[veye_xumm]

@coolmitch
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。

[coolmitch]

@veye_xumm
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。

[veye_xumm]

@coolmitch
我也是按照这个步骤做的。但是cmake阶段报错了。

[coolmitch]

@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)

@coolmitch
请问你的cmake版本是？
我的是3.10.2

[veye_xumm]

@coolmitch
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：

@veye_xumm
cmake --version
cmake version 3.10.2

CMake suite maintained and supported by Kitware (kitware.com/cmake).
我的也是 3.10.2
所以會不會是有什麼 dependent lib 沒有安裝完全？

[coolmitch]

@veye_xumm
升級後，開機看到這個

不過我還是讓他去跑著測試了...
今晚先用 python3 的程式跑跑看...

[veye_xumm]

@coolmitch
我这边老化一夜，已经运行38000+次数，现在还是稳定的。 期待你的结果。

[coolmitch]

@veye_xumm 我昨晚也跑了 22000+ 次，這樣應該就過了。所以是什麼原因造成的？
