It is very exit to received an chinese friends reply.

Maybe I did not describe my difficulty clearly.I install all the parts of Directx9.0c.

At fact,I always develop project based on DShow.And follow your remind,I reinstall the DirectX9.0c,

it is same as the last time.

I said I can not find dshow.h,just means I can not find it in the ptlib/dshow.h.

I ever remember it need #include <ptlib/dshow.h>.but today,I do not find this code.

At last,Do you sure it support dshow just install directx9 without any other set?

Dear JobsGuo,

Please double check if you have installed all the parts of DirectX 9.0 SDK.

I can find dshow.h in \DXSDK\include\

If you have any other problem, you can contact me.

You are Chinese too 微笑图释

Good luck,

Ryan

Subject: [h323plus] how to support directshow

Hi,all.

when I compile the ptlib-v2_0_1,I find the config in ptbuildopts.h show below:

/////////////////////////////////////////////////
//
// DirectX Support (Windows only)
//

#ifndef _WIN32_WCE
#define P_DIRECTSOUND 1
#undef P_DIRECTSHOW
#undef P_VFW_CAPTURE
#endif

So I can not get the directshow support.but I can get the directsound support.I indeed install directx 9.0c.so it can find the directx file.

but why it can not find the directshow? Besides,I also can not find the dshow.h.

Who can help me ?thanks!
