請問有人可以大概告訴我~~ 這段程式碼有哪段是用攝影機抓照片且一秒抓幾張的是哪段呢? 或者是根本沒有這段~~ 這段程式碼大概是做什麼用的 謝謝大家~~幫我解決一下問題 <textarea class="cpp" rows="10" cols="60" name="code"> extern String FilePath; extern bool StartCapture; extern "C" AM_MEDIA_TYPE g_StillMediaType; class SampleGrabberCallback : public ISampleGrabberCB { public: //static SYSTEMTIME st; //--計算系統時間 // Fake referance counting. STDMETHODIMP_(ULONG) AddRef() { return 1; } STDMETHODIMP_(ULONG) Release() { return 2; } STDMETHODIMP QueryInterface(REFIID riid, void **ppvObject) { if (NULL == ppvObject) return E_POINTER; if (riid == __uuidof(IUnknown)) { *ppvObject = static_cast(this); return S_OK; } if (riid == __uuidof(ISampleGrabberCB)) { *ppvObject = static_cast(this); return S_OK; } return E_NOTIMPL; } STDMETHODIMP SampleCB(double Time, IMediaSample *pSample) { return E_NOTIMPL; } STDMETHODIMP BufferCB(double Time, BYTE *pBuffer, long BufferLen) { static int kk = 1; if( !StartCapture ) { kk = 1; return S_OK; } if ((g_StillMediaType.majortype != MEDIATYPE_Video) || // (g_StillMediaType.subtype != MEDIASUBTYPE_RGB24) || (g_StillMediaType.formattype != FORMAT_VideoInfo) || (g_StillMediaType.cbFormat < sizeof(VIDEOINFOHEADER)) || (g_StillMediaType.pbFormat == NULL)) { return VFW_E_INVALIDMEDIATYPE; } String count; count = FormatFloat("#000",kk) ".bmp"; kk ; VIDEOINFOHEADER *pVideoHeader = (VIDEOINFOHEADER*)g_StillMediaType.pbFormat; if(pVideoHeader==NULL) return E_FAIL; BITMAPINFO BitmapInfo; ZeroMemory(&BitmapInfo, sizeof(BitmapInfo)); CopyMemory(&BitmapInfo.bmiHeader, &(pVideoHeader->bmiHeader), sizeof(BITMAPINFOHEADER)); HBITMAP hBitmap; hBitmap = ::CreateDIBitmap(::GetDC(NULL), &(pVideoHeader->bmiHeader), CBM_INIT, pBuffer, &BitmapInfo, DIB_RGB_COLORS); if(hBitmap==NULL) return E_FAIL; BITMAP bitmap; Graphics::TBitmap *Bitmap1=new Graphics::TBitmap(); Bitmap1->Handle=hBitmap; Bitmap1->PixelFormat = pf24bit; // 調整影像 PixelFormat // 取得 Bmp 的 Width & Height GetObject(hBitmap,sizeof(BITMAP),&bitmap); Bitmap1->SaveToFile(count); delete Bitmap1; return S_OK; } }; </textarea>

沒有這段
這只有部分程式
只有開始存影像部分
