AVI Writer OpenCV访问冲突 [英] AVI Writer OpenCV access violation

问题描述

CvVideoWriter *writeravi = cvCreateVideoWriter("C:\\outavi.avi",CV_FOURCC('D','I','V','X'),fps,cvSize(frameW,frameH),isColor);

for(int stepframe=0;stepframe<numFrames;stepframe++)
{
	cvGrabFrame(captureavi);          
	imgavi=cvRetrieveFrame(captureavi);
	int t= cvWriteFrame(writeravi,imgavi);  
	cvShowImage("image",imgavi);
	cvWaitKey(20);
}

它给了我违反aceess的习惯，(even writeravi = 0x003ecd18)

如果我输入"0"或"-1"而不是CV_FOURCC("D"，"I"，"V"，"X")可以，但是)代表未压缩输出& -1给出了Dialg框来选择压缩类型，Intel indeo video 4.5可以从中使用压缩类型.

但是在我的应用程序中，我不能使用)或-1 7我要压缩输出.

[edit]删除了SHOUTING，添加了代码块，将我的内容作为纯文本..."选项已禁用-OriginalGriff [/edit]

It gives me aceess violation,(even writeravi=0x003ecd18 )

if i put "0" or "-1" instead of CV_FOURCC(''D'',''I'',''V'',''X'') it works but ) stands for uncompress output & -1 gives dialg box to select compression type , from which Intel indeo video 4.5 works for me.


But in my applicationh i cant use ) or -1 7 i want compresss output.

[edit]SHOUTING removed, Code block added, "Treat my content as plain text..." option disabled - OriginalGriff[/edit]

推荐答案

您在以下位置指定DIVX您的代码不起作用.出现对话框时，选择不是DIVX的Intel indeo视频.我认为未安装DIVX，因此无法正常工作.请查看链接以查看FOURCC编解码器列表并更改编解码器，或者您可以安装DIVX并再次尝试.

You specify DIVX in your code which doesn''t work. When you get a dialog you select Intel indeo video which isn''t DIVX. I think DIVX isn''t installed and therefore won''t work. Have a look at the link to check out the FOURCC codec list and change the codec or you could install DIVX and have another try.
