Mirage driver released under GPL!

[levk]

To whom it may concern.

Good news ladies and gentlemen!
Mirage driver, a well-known high-performance yet reliable Windows desktop
capture engine (previously known as Df Mirage driver) used with
TightVNC and many other products is now available in Open Source,
under GPL license.
It's the only working mirror driver available in source to date!
Feel free to use it in any noncommercial (Open Source) product.
Enjoy full access to its source code!

Welcome to the SourceForge project page: http://mirage-driver.sourceforge.net.

Project mirrors will appear soon on Novell forge and other
Open Source hostings as well.

Anyone interested in commercial licensing should contact
project administrator and copyright holder Lev Kazarkin:
levk@users.sourceforge.net
lev.kazarkin@gmail.com
levk@mail.tomsknet.ru

Sincerelly,

Lev,

The SF.NET directory seems to be empty.

Cheers,

The project is empty, no downloads, no website, no files in CVS. A joke? Vaporware?

Feel free to use it in any noncommercial (Open Source) product.

That restriction is a violation of the GPL; the GPL protects the right to release a GPL'd project commercially, so long as they adhere to the GPL and release the required code.

One good example is the Quake 3 engine, which was GPL'd. A commercial game may use the GPL'd engine without a traditional engine license, and charge as much as they want for their game; they simply need to release the full sourcecode (but not the media, which is what the game is really all about).

Remember, opensource != non-commercial.

That restriction is a violation of the GPL; the GPL protects the right to release a GPL'd project commercially, so long as they adhere to the GPL and release the required code.

The GPL does not require anyone to release the source code, instead it requires that if you make the binaries available, the corresponding source must be made available. This is by far not the same as having to release the source.

But this doesn't matter anyway. Currently it looks like classical VaporWare

the address was changed.

the mirage driver is also available for EchoVNC => 2.10

More than one year, nothing in the CVS or on the website.

VaporWare (tm)?

Hi!
I am developing an application whcih will make a copy of Server Desktop to the client System as it is, Like VNC and other Remote Desktop applications.. I need to capture images as efficiently as possible. for this I am trying to use "Mirage Driver", but I am unable to run "ExtEscape()" function successfully.. here is my code snippet.

Code: Select all

#define MAP 1030   
  
  
typedef struct _CHANGES_RECORD   
{   
    ULONG type;  //screen_to_screen, blit, newcache,oldcache   
    RECT rect;   
    RECT origrect;   
    POINT point;   
    ULONG color; //number used in cache array   
    ULONG refcolor; //slot used to pase btimap data   
}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;   
  
typedef struct _GETCHANGESBUF   
    {   
     PCHANGES_BUF buffer;   
     PVOID Userbuffer;   
    }GETCHANGESBUF;   
  
  
  
HDC l_gdc = ::CreateDC(TEXT("DISPLAY"), NULL, NULL, NULL);   
    if (!l_gdc)   
    {   
        printf("can't create DC on \"%s\"\n",   
            m_devname);   
        return FALSE;   
    }   
  
    oldCounter = 0;   
    int drvCr = ExtEscape(   
        l_gdc,   
        MAP,   
        0, NULL,   
        sizeof(GETCHANGESBUF), (LPSTR) &bufdata);   
    DeleteDC(l_gdc);   
  
    if (drvCr <= 0)   
    {   
        printf(MAP call returned 0x%x\n",   
            drvCr); /*Error*/   
        return FALSE;   
    }  

I have successfully called CreateDC Successfully.. but the ExtEscape() function is always returning 0 for MAP Escape (1030), I have tried the C# version of the above code and same problem there.. Mirage Driver is installed properly and is being displayed in Device Manager.. I am using Windows XP and VS 2005. Please help me out. if any one have some code snippet for me I will really appreciate it.
Thanks

Hi!
now I have successfully created the driver handle and have loaded it.. But I am facing another problem... I will really appreciate any help from any one.. here is the scenario..

After loading the driver when it has successfully initialized, and I have valid values in "GETCHANGESBUF", then for the first test I want to copy whole of screen image in to a bmp file.. as "GETCHANGESBUF.UserBuffer" contains the pointer to first byte of screen, from that pointer I want to get whole of the screen image.. here is the fucntion I have written for it.

void CopyToBuffer(BYTE *destbuff, const BYTE *srcbuffpos)

{

RECT m_bmrect;

m_bmrect.left = 0;

m_bmrect.top = 0;

m_bmrect.right = GetSystemMetrics(SM_CXSCREEN);

m_bmrect.bottom = GetSystemMetrics(SM_CYSCREEN);




RECT rect;

rect.left = 0;

rect.top = 0;

rect.right = GetSystemMetrics(SM_CXSCREEN);

rect.bottom = GetSystemMetrics(SM_CYSCREEN);



const int crect_re_vd_left = rect.left - m_bmrect.left;

const int crect_re_vd_top = rect.top - m_bmrect.top;



_ASSERTE(crect_re_vd_left >= 0);

_ASSERTE(crect_re_vd_top >= 0);



const int bytesPerPixel = 32 / 8;

const int m_bytesPerRow = GetSystemMetrics(SM_CXSCREEN) * bytesPerPixel;



const int bmoffset = (m_bytesPerRow * crect_re_vd_top) + (bytesPerPixel * crect_re_vd_left);



BYTE *destbuffpos = destbuff + bmoffset;

srcbuffpos += bmoffset;



const int widthBytes = (rect.right - rect.left) * bytesPerPixel;

std::ofstream myfile;

myfile.open("C:\\image.bmp",std::ios::binary | std::ios::out);

for (int y = rect.top; y < rect.bottom; y++)

{

memcpy(destbuffpos, srcbuffpos, widthBytes);

for(int i=0;i<widthBytes;i++)

myfile << destbuffpos;

srcbuffpos += m_bytesPerRow;

destbuffpos += m_bytesPerRow;

}

myfile.close();

}



here is the call to the function CopyToBuffer()



GETCHANGESBUF buf = {0};

void Connect()

{

int res = ExtEscape(hdc, dmf_esc_usm_pipe_map, 0, NULL, sizeof(buf), (LPSTR)&buf);

if (res <= 0)

{

/*Error in mapping*/

}

}









int _tmain(int argc, _TCHAR* argv[])

{

OpenDriver(_T("Mirage Driver"),_T("dfmirage"));

Load();

Connect();

/*Get the update screen*/

BYTE *screenBuffer = new BYTE[ GetSystemMetrics(SM_CXSCREEN) * GetSystemMetrics(SM_CYSCREEN) * 4];

CopyToBuffer(screenBuffer,(BYTE *)buf.Userbuffer);

}



The File I am writing to doesn't become a valid bmp file... please suggesst some solution, Please if you have any code for getting bytes from the initial pointer do send it to me...
