[問題] OpenCV存取影片問題 (avi檔)
我是用OpenCV 2.0，在VC 2008上工作
我最近快被這個寫影片的問題搞瘋，簡單來說就是cvCreateVideoWriter(AviFileName,
CV_FOURCC('X', 'V', 'I', 'D') ,FPS,AviSize,AviColor); 中第2個參數有問題，
不論我用XVID,DIVX或是raw file等等都失敗。我也試過從現有的avi檔做拿FOURCC的值
例如cvGetCaptureProperty(capturesrc, CV_CAP_PROP_FOURCC)來當我的FOURCC
但是依然失敗。
我安裝過ffdshow，我安裝過最新的Xvid codec，我實在不知道是哪裡的問題
跑出的錯誤訊息是如下 http://ppt.cc/;9g2
code大家有興趣看的話如下
int main()
{
CvCapture *capture;
IplImage *frame;
capture=cvCreateCameraCapture(0);
cvNamedWindow("Webcam",0);
CvVideoWriter *writer;
char AviFileName[]="Output.avi";
int FPS = 25;
CvSize AviSize = cvSize(320,240);
int AviColor = 1;
writer=cvCreateVideoWriter(AviFileName,CV_FOURCC('X', 'V', 'I', 'D')
,FPS,AviSize,AviColor);
int i=0;
while(true)
{
frame = cvQueryFrame(capture);
cvWriteFrame(writer,frame);
cvShowImage("Webcam",frame);
if(cvWaitKey(20)>0) break;
i++;
}
cvReleaseCapture(&capture);
cvReleaseVideoWriter(&writer);
cvDestroyWindow("Webcam");
}
有請各位大神解答，小弟在此叩謝了
