我需要在Mac os X 10.8上使用OpenCV
从GIge相机保存灰度视频。我使用以下代码:
namedWindow("My video",CV_WINDOW_AUTOSIZE);
Size frameSize(659, 493);
VideoWriter oVideoWriter ("MyVideo.avi",-1, 30, frameSize, false);
While(1)
{
...
Mat Image=Mat(Size(GCamera.Frames[Index].Width,GCamera.Frames[Index].Height),CV_8UC1,GCamera.Frames[Index].ImageBuffer);
oVideoWriter.write(Image);
...
}
我收到此错误:
最佳答案
我是这样写的:
VideoWriter oVideoWriter ("MyVideo.avi",CV_FOURCC('M','J','P','G'), 30, frameSize);
While(1)
{
Mat Image=Mat(Size(GCamera.Frames[Index].Width,GCamera.Frames[Index].Height),CV_8UC1,GCamera.Frames[Index].ImageBuffer);
Mat colorFrame;
cvtColor(Image, colorFrame, CV_GRAY2BGR);
oVideoWriter.write(colorFrame);
}
关于c++ - 使用opencv创建灰度视频,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/23066542/
