Update Multimedia (Compact 7)
3/12/2014
If your BSP includes multimedia support, you must make the following changes. These changes include access to the frame buffer and new locations for camera header files.
Display: Video Memory
In Windows Embedded CE 6.0, you could get a pointer to the frame buffer and then update the display by writing directly to the frame buffer. However, hardware-accelerated graphics systems do not guarantee the format or location of data stored in the frame buffer. Therefore, direct pointers to the frame buffer are not supported in Windows Embedded Compact 7. Other than the display driver, functions must not directly access the frame buffer. You must rewrite applications or other drivers that directly access the frame buffer so that your applications use supported APIs.
Camera
The following camera header files have been renamed and moved in Windows Embedded Compact 7.
| Windows Embedded CE 6.0 Names | Windows Embedded Compact 7 Names |
|---|---|
public\common\oak\driver\capture\ camera\layered\inc\dgbsettings.h |
public\common\ddk\inc\cameradebug.h |
public\common\oak\driver\capture\ camera\layered\inc\pindriver.h |
public\common\ddk\inc\camerapindriver.h |
Scan through camera source files looking for these Windows Embedded CE 6.0 camera files and replace the include names with the new Windows Embedded Compact 7 names.
