Hi , i would like to implement this function: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/ht... Here fpProc is a pointer to the preview callback function Applications use this to get access to the videodata. Right now i already have a preview window.
If i'm correct it is similar to this function:http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/ht...
Here the structure LPVIDEOHDR lpVHdr contains the information about the videodata. My question is how all of this could be implemented; right now i have :
case WM_CAP_SET_CALLBACK_FRAME: LPVIDEOHDR lpVideoHdr; //defined in vfw.h typedef LRESULT (CALLBACK * CAPVIDEOCALLBACK)(HWND hwnd, LPVIDEOHDR lpVideoHdr); CAPVIDEOCALLBACK *framecallback = (CAPVIDEOCALLBACK *)lParam;
{so what goes here? }
return TRUE; break;
So how could i pass the data in lpVideoHdr to the application? Any help appreciated as i'm still quite a beginner in this :)
Regards
