使用自己编译的OPENCV4.8.0打开SC3336摄像头，图像异常。是还需要额外的初始化代码吗？

各位大神们好，我用自己编译的OPENCV4.8.0打开SC3336摄像头，图像显示异常：
Code: Select all
cv:Mat buf, im;
this->pCap->open("/dev/video11");
this->pCap->set(cv::CAP_PROP_FRAME_WIDTH, width);
this->pCap->set(cv::CAP_PROP_FRAME_HEIGHT, height);
(*this->pCap) >> buf;
if(buf.empty()) {
LOG(ERROR) << "Nothing!";
return false;
} else {
cv::cvtColor(buf, im, cv::COLOR_YUV2BGR_UYVY);
LOG(INFO) << "Image width: " << im.size().width << " height: " << im.size().height;
return true;
}
我想问下，rk1106对摄像头操作是否还有前置的初始化过程？

改用OpenCV-mobile-4.9.0后，无法获取到图像：

有注意用 killall rkipc 关闭rkipc进程吗，opencv-mobile用到mpp库和系统开机运行的rkipc冲突

是的，确认rkipc已经kill，进程中已不存在rkipc

这是我之前编译的4.9.0版本的，测试捕获一帧图片，你可以试一下

测试你这边编译好的opencv-mobile-test也是一样的
我自己的也是同样情况：

你的系统是在 SPI NAND Flash 上的还是 TF 卡上的，我在 luckfox-pico plus TF 卡上运行的结果：
之前也遇到过运行不了的情况，似乎和 DMA 有关，很遗憾我没记录下来

是在SPI NAND上运行的，不过如果SPI NAND有DMA冲突的话，那rkipc那个也应该要有问题才是
