将IMediaSample加载到IDirect3DSurface9 [英] Loading IMediaSample to IDirect3DSurface9

问题描述

将IMediaSample加载到IDirect3DSurface9的最快方法是什么?
我使用位图.还有另一种方法吗?
使用Bitmap将IMediaSample加载到IDirect3DSurface9时，我获得了所有处理器时间，其视频播放器应用程序的分辨率为1440 x 480，频率为24赫兹. 在我的2个处理器系统上，我得到以下结果:

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
StereoRendererLR.ax             10.61
MP4SDECD.DLL                    7.37
MainFilter.ax                   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-英特尔处理器驱动程序
ntkrnlpa.exe-Windows内核
StereoRendererLR.ax-我的视频渲染器模块

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

推荐答案

内核执行权限是由于我的应用程序在内核中等待功能而引起的.

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