What is the fastest way to load IMediaSample to IDirect3DSurface9?
I use Bitmap. Is there another way?
When loading IMediaSample to IDirect3DSurface9 using Bitmap, i get all processor time running my video player application with video with resolution 1440 x 480 and frequency 24 Hertz.
On my 2 processors system i have following results:
Module Name             64-bit  Timer samples
intelppm.sys                    31.96
ntkrnlpa.exe                    23.72             10.61
MP4SDECD.DLL                    7.37                   5.19
win32k.sys                      4.03
nvlddmkm.sys                    3.36
halmacpi.dll                    2.39

8 modules, Total: 87761 samples, 88.63% of shown samples

intelppm.sys - Intel processor driver
ntkrnlpa.exe - Windows kernel - my video renderer module
Is it possable to decrease Intel processor driver and Windows kernel percentage?

1 solution

Kernel percatage was caused be my application, by functions, that wait in kernel.
