帮顶 支持下楼主

没有试过，帮忙顶一下！

初步看了一下老是在CDDrawObject::UpdateAndFlipSurfaces( )函数的 hr = m_pPrimary->Flip(NULL, 0) ; 处执行FLIP失败.错误如下，错误码为6,Flip函数执行结果为0x887600d4．

++++4444::CDDrawObject::UpdateAndFlipSurfaces( )----the dwErr is 6,the hr is 0x887600d4

不知道为什么，不知道怎么去调．过滤器图表建的不对？但我看那些初始化函数执行的都是成功的啊！

[xqhrs232]

程序可以跑起来，但显示是黑的，啥都看不到．对应的多媒体文件的解码器肯定有是有了，因为我用ＭＥＤＩＡＰＬＡＹＥＲ是可以成功播放并显示出来的．

[xqhrs232]

系统里面用到了Overlay Mixer，系统也应该是支持的．因为创建是成功的．硬件对Overlay也是支持的，显示驱动也支持Overlay功能．

[xqhrs232]

Overlay Mixer用不了,难道要去用IDirectDrawVideo接口?

D:\DXSDK\Samples\C++\DirectShow\Players\DDrawXCL为PC下相同的例子,但是可以跑起来!!!

怪!!!

会不会是创建的表面不对啊！！！
PixelFormat :12
CreateSurface:0

enum EDDGPEPixelFormat

PC下跟WINCE下的例子在逻辑上有一些不一样,不知道为什么?!

我参考PC下的例子对WINCE下的进行对应的修改,还是不行,奇怪了呢(表面FLIP的时候还是失败).觉得没什么特别的地方啊!
怎就这么怪呢?不知道问题在那里.

[xqhrs232]

难道DDRAW初始化有问题?初始化参数怎么是下面这样的.

#define SCRN_WIDTH 800
#define SCRN_HEIGHT 600

#define SCRN_BITDEPTH 8

[qthsrs232]

WINCE60下的Overlay Mixer filter 压根就不支持IDDrawExclModeVideo接口,但WINCE60下的这个应用程序怎么还去查询这个接口???并且还不失败!!!诡异的很.


hr = CoCreateInstance(CLSID_OverlayMixer, NULL, CLSCTX_INPROC, IID_IBaseFilter, (LPVOID *)ppOvM) ;

//----------------------------------

IDDrawExclModeVideo *pDDXM ;

hr = pOvM->QueryInterface(IID_IDDrawExclModeVideo, (LPVOID *)&pDDXM) ;
