Samples
screenrecorder using bitblt
same screenrecorder with Mirror Driver
Get rectangle list of changed screen parts
The small samples help you to implement a Mirror Driver in your own application
VIDEODRIVER Class
VIDEODRIVER();
Initialize MD driver Class
Usage:
VIDEODRIVER *mydriver= new VIDEODRIVER;
Don’t forget to delete
delete mydriver;
void VIDEODRIVER_start(int x,int y,int w,int h,int depth);
Attach the Mirror Driver
position left top corner
x=left
y=top
w=screen width
h=screen height
depth= 8/16/32, special case 0=use current depth
Usage:
1) Mirror current desktop with same size and depth
HDC hDisplayDC = CreateDC("DISPLAY",NULL,NULL,NULL);
int cxWidth= GetDeviceCaps(hDisplayDC,HORZRES) ;
int cyHeight = GetDeviceCaps(hDisplayDC,VERTRES);
mydriver->VIDEODRIVER_start(0,0,cxWidth,cyHeight,0);
2) Mirror current desktop with same size and depth=32
HDC hDisplayDC = CreateDC("DISPLAY",NULL,NULL,NULL);
int cxWidth= GetDeviceCaps(hDisplayDC,HORZRES) ;
int cyHeight = GetDeviceCaps(hDisplayDC,VERTRES);
mydriver->VIDEODRIVER_start(0,0,cxWidth,cyHeight,32);
WARNING
If you mirror a part of the desktop, moving a window
in your clipped region is not proper updated.
Sample:
mydriver->VIDEODRIVER_start(10,10,320,320,32);
void VIDEODRIVER_Stop();
Detach the Mirror Driver
Usage:
mydriver->VIDEODRIVER_Stop();
BOOL HardwareCursor();
Mirror Driver show cursor as blit
Usage:
mydriver->HardwareCursor();
see screentoavi_MD sample
BOOL NoHardwareCursor();
Mirror Driver eliminate cursor as part of the blits
Usage:
mydriver->NoHardwareCursor();
char *myframebuffer;
This is a memory buffer that contain your screen in the format you specified
32 RGBARGBARGBARGBA
Instead of using bitblit you can now use memcpy to get access to the screen data.
Usage:
see screentoavi_MD sample
PCHANGES_BUF mypchangebuf;
This is a ringbuffer that contain the changed parts.
format:
typedef struct _CHANGES_RECORD
{
ULONG type; //screen_to_screen, blit, newcache,oldcache
RECT rect;
POINT point;
}CHANGES_RECORD;
typedef CHANGES_RECORD *PCHANGES_RECORD;
typedef struct _CHANGES_BUF
{
ULONG counter;
CHANGES_RECORD pointrect[MAXCHANGES_BUF];
}CHANGES_BUF;
typedef CHANGES_BUF *PCHANGES_BUF;
The driver record the rect changes, the application need to remember the old position
to extract the needed updates
Usage:
See changed_screen_parts sample
