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

veye_xumm

@coolmitch
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....

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)

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：

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？

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？

veye_xumm

@coolmitch
应该是我这边程序在处理close的时候，对资源的释放上有逻辑不完善的地方。希望你后面也继续测试观察吧。嵌入式端控制frequency的问题，我再研究一下。

coolmitch

@veye_xumm 瞭解。昨晚的還繼續在跑。我今天會做另一個測試站雙重測試。uvccamera 的參數看有沒有辦法讓有支援的都給出來，這樣在 linux 這邊會比較好處理（之前用 python 的那個 fourcc 的處理方式，因為沒有完整 uvc 的參數，搞了很久才找到那個怪方法...）

veye_xumm

@coolmitch
这个涉及到的改动太大了。暂时做不了所有参数都支持。现在我们只能是把摄像头默认参数调到最好。
另外就是你说的frequency hz设置的问题，需要解决一下。

coolmitch

@veye_xumm
對了，在 CS-USB-IMX307 新版韌體更新後，插入主機時會出現以下訊息，請問那些 Failed to query (GET_DEF) UVC control ... 是否就是 driver 要去讀取 uvccamera 參數時讀不到的錯誤？

这个就是对于uvc参数支持不完善所体现出来的。
