#14 Dual monitor issue

[Andy Milne]

If you've got multiple monitors then it will only capture video from the primary monitor.

The first problem is in vscapView.cpp, at line 995 ff.

In the function CVscapView::OnRecordStart, we have

maxxScreen = GetDeviceCaps\(hScreenDC,HORZRES\);
maxyScreen = GetDeviceCaps\(hScreenDC,VERTRES\);        
FixRectSizePos\(&rc,maxxScreen, maxyScreen\);

This constrains the capture window to the size of the primary display.

The 1st 2 lines should check the *virtual screen* (bounding rect of all monitors) size using

maxxScreen = GetSystemMetrics\(SM\_CXVIRTUALSCREEN\);
maxyScreen = GetSystemMetrics\(SM\_CYVIRTUALSCREEN\);

Elsewhere it's necessary to remove the assumption that the capture area must be in x>=0, y>=0, so that a secondary monitor to the left of the primary one can be captured, and instead have x >= GetSystemMetrics(SM_XVIRTUALSCREEN), y >= GetSystemMetrics(SM_CYVIRTUALSCREEN). Likely places for this include FixedRegion.cpp and the function FixRectSizePos() called above (vscapView.cpp, line 1925 ff).

Multiple monitor support has been added and will be available in the next release.

A beta version of this feature is available by downloading and building the latest version of the source.
