HBITMAP to AVI问题(谁能解决100分相送)

Question

我用的是http://www.codeproject.com/bitmap/createmovie.asp 的CAviFile类,但是在我压缩
我的HBITMAP对象时总是
if (FAILED(AVISaveOptions(NULL, 0, 1, &m_pAviStream, (LPAVICOMPRESSOPTIONS FAR *) &m_AviStreamInfo)))
{
goto TerminateInit;
}报错不知道什么原因，我压得是16位色函数的具体代码如下：
HRESULT CAviFile::AppendFrameFirstTime(HBITMAP hBitmap)
{
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 TerminateInit;
} ZeroMemory(&bmpInfo,sizeof(BITMAPINFO));
bmpInfo.bmiHeader.biSize=sizeof(BITMAPINFOHEADER);

{

goto TerminateInit;
} ZeroMemory(&m_AviStreamInfo,sizeof(AVISTREAMINFO));
m_AviStreamInfo.fccType=streamtypeVIDEO;
m_AviStreamInfo.fccHandler=mmioFOURCC('M','P','G','4');
m_AviStreamInfo.dwScale=1;
m_AviStreamInfo.dwRate=1; //15fps
m_AviStreamInfo.dwQuality=-1; //Default Quality
m_AviStreamInfo.dwSuggestedBufferSize=nMaxWidth*nMaxHeight*2;
    SetRect(&m_AviStreamInfo.rcFrame,0,0,bmpInfo.bmiHeader.biWidth,bmpInfo.bmiHeader.biHeight);

{

Answer 1

顶一下，我压缩的是24位RGB数据，也出现这种情况，望高手帮忙！

Answer 2

24位 rgb 直接 用就 可以了,,不用压缩...
我也正在想 我的 8位 改怎么显示哦??

Answer 3

16位的如下: 本人机器上通过 运行,显示正确:HRESULT CAviFile::AppendFrameFirstTime(HBITMAP hBitmap)
