Hello,

I am still in trouble working with directdraw display driver in WinCE
6.0. The driver works fine with the DDraw DDTK testcases.But when i
try to play WMV files with CE Media player, it uses the GDI path
instead of using Directdraw and overlay surface. Though it creates YUV
overlay surface(UYVY) , the renderer uses GDI to play the file. The
overlay min/max stretching values are same as that of CE 5.0 version
which works fine in 5.0.

The debug information from quartz couldnt help me to fix the
problem.Can anybody please tell me the possible reasons ?. I am not
using any third party filters.


regards,

Stupid question but you have the dshow renderer in (SYSGEN_DSHOW_VIDREND) ?

Did/Can you try the display driver in CE5.0?

I dont know what is wrong with the query.
The original driver is perfectly working in ce 5.0 and i am porting it
to ce 6.0. The video renderer is also included in the OS image. My
problem is that, the video renderer is not using Directdraw path
(overlay/flipping) when i try to play WMV files.It creates flippable
overlay surface in YUV format ;but not using it for rendering.
