无法使用avimakecompressedstream创建压缩流 [英] Unable to create compressed stream with avimakecompressedstream

问题描述

我正在尝试从位图文件创建avi

我无法创建压缩流

我正在使用64位操作系统

我尝试了win32和x64的调试和发布选项



程序正在编译成功但运行时间错误...



我尝试过：

I'm trying to create avi from bitmap files
I'm not able to create compressed stream
I'm using 64 bit os
I tried both debug and release option's with win32 and x64

Program is compiling successfully but getting run time error...

What I have tried:

HRESULT	CAviFile::AppendFrameFirstTime(int nWidth, int nHeight, LPVOID pBits,int nBitsPerPixel)
{
	int	nMaxWidth=GetSystemMetrics(SM_CXSCREEN),nMaxHeight=GetSystemMetrics(SM_CYSCREEN);

	BITMAPINFO	bmpInfo;

	m_hAviDC=CreateCompatibleDC(NULL);
	if(m_hAviDC==NULL)	
	{
		MessageBox(NULL,"Unable to Create Compatible DC","Error",MB_OK|MB_ICONERROR);
		goto TerminateInitBits;
	}

	ZeroMemory(&bmpInfo,sizeof(BITMAPINFO));
	bmpInfo.bmiHeader.biPlanes=1;
	bmpInfo.bmiHeader.biWidth=nWidth;
	bmpInfo.bmiHeader.biHeight=nHeight;
	bmpInfo.bmiHeader.biCompression=BI_RGB;
	bmpInfo.bmiHeader.biBitCount=nBitsPerPixel;
	bmpInfo.bmiHeader.biSize=sizeof(BITMAPINFOHEADER);
	bmpInfo.bmiHeader.biSizeImage=bmpInfo.bmiHeader.biWidth*bmpInfo.bmiHeader.biHeight*bmpInfo.bmiHeader.biBitCount/8;
	
	if(bmpInfo.bmiHeader.biHeight>nMaxHeight)	nMaxHeight=bmpInfo.bmiHeader.biHeight;
	if(bmpInfo.bmiHeader.biWidth>nMaxWidth)	nMaxWidth=bmpInfo.bmiHeader.biWidth;

	m_hHeap=HeapCreate(HEAP_NO_SERIALIZE,nMaxWidth*nMaxHeight*4,0);
	if(m_hHeap==NULL)
	{
		//MessageBox(NULL,"Unable to Allocate Memory","Error",MB_OK);
		goto TerminateInitBits;
	}
	
	m_lpBits=HeapAlloc(m_hHeap,HEAP_ZERO_MEMORY|HEAP_NO_SERIALIZE,nMaxWidth*nMaxHeight*4);
	if(m_lpBits==NULL)	
	{	
		//MessageBox(NULL,"Unable to Allocate Memory","Error",MB_OK);
		goto TerminateInitBits;
	}

	if(FAILED(AVIFileOpen(&m_pAviFile,m_szFileName,OF_CREATE|OF_WRITE,NULL)))
	{
		//MessageBox(NULL,"Unable to Create the Movie File","Error",MB_OK|MB_ICONERROR);
		goto TerminateInitBits;
	}

	ZeroMemory(&m_AviStreamInfo,sizeof(AVISTREAMINFO));
	m_AviStreamInfo.fccType=streamtypeVIDEO;
	m_AviStreamInfo.fccHandler=VIDEOCODEC;
	m_AviStreamInfo.dwScale=1;
	m_AviStreamInfo.dwRate= FPS;	//Frames Per Second;
	m_AviStreamInfo.dwQuality=-1;	//Default Quality
	m_AviStreamInfo.dwSuggestedBufferSize=nMaxWidth*nMaxHeight*4;
    SetRect(&m_AviStreamInfo.rcFrame,0,0,bmpInfo.bmiHeader.biWidth,bmpInfo.bmiHeader.biHeight);
	strcpy(m_AviStreamInfo.szName,"Video Stream");

	if(FAILED(AVIFileCreateStream(m_pAviFile,&m_pAviStream,&m_AviStreamInfo)))
	{
		//MessageBox(NULL,"Unable to Create Stream","Error",MB_OK|MB_ICONERROR);
		goto TerminateInitBits;

	}

	ZeroMemory(&m_AviCompressOptions,sizeof(AVICOMPRESSOPTIONS));
	m_AviCompressOptions.fccType=streamtypeVIDEO;
	m_AviCompressOptions.fccHandler=m_AviStreamInfo.fccHandler;
	m_AviCompressOptions.dwFlags=AVICOMPRESSF_KEYFRAMES|AVICOMPRESSF_VALID;//|AVICOMPRESSF_DATARATE;
	m_AviCompressOptions.dwKeyFrameEvery=15;
	//m_AviCompressOptions.dwBytesPerSecond=1000/8;
	//m_AviCompressOptions.dwQuality=100;

	if(FAILED(AVIMakeCompressedStream(&m_pAviCompressedStream,m_pAviStream,&m_AviCompressOptions,NULL)))
	{
//////////////////////////////////////////////////////////////////////
                //Here I'm this msgbox is showing......
		MessageBox(NULL,"Unable to Create Compressed Stream","Error",MB_OK);
		goto TerminateInitBits;
//////////////////////////////////////////////////////////////////////
	}

	if(FAILED(AVIStreamSetFormat(m_pAviCompressedStream,0,(LPVOID)&bmpInfo,bmpInfo.bmiHeader.biSize)))
	{
		//MessageBox(NULL,"Unable to Set Format","Error",MB_OK);
		goto TerminateInitBits;
	}

	nAppendFuncSelector=2;		//Point to UsualAppend Function

	return AppendFrameUsual(nWidth,nHeight,pBits,nBitsPerPixel);

TerminateInitBits:

	ReleaseMemory();	MessageBox(NULL,"Error Occured While Rendering the Movie","Error",MB_OK|MB_ICONERROR);

	return E_FAIL;

    }

推荐答案

您没有告诉我们发生了什么样的运行时错误。



错误的可能来源可能是您计算 BITMAPINFOHEADER [ ^ ] biSizeImage 成员错误。请参阅上面链接中的计算表面步幅。

You did not tell us what kind of runtime error occurs.

A possible source of the error might be that that your calculation of the BITMAPINFOHEADER[^] biSizeImage member is wrong. See "Calculating Surface Stride" at the above link.
