RK3399pro使用opencv无法打开视频

      在RK3399pro 上面编译安装opencv3.4.7和FFmpeg4.1，在调用VideoCapture函数打开本地视频文件时，一直报错，报错信息如下：

复制代码      请问各位也遇到这样的问题了吗？

請問有解決了嗎
目前我在rv1126上面, sdk裡面沒有videoio.a,
後來自己下載跟sdk同版本的opencv自己編譯
呼叫VideoCapture函数打开本地视频文件时
也出現VIDIOC_REQBUFS: Inappropriate ioctl for device
請問後來是如何處理？
請問這是rock chip的問題嗎？？
謝謝
