Dear JobsGuo,
 
I have checked my home PC, I found the same problem as you said. (Only DirectSound support, No DirectShow support)
 
I think that's caused by the configure.exe program given by ptlib.
 
By the way, in my experience, ptlib is most useful for platform independent. DirectX is only a feature for Windows (actually, windows for PC), I don't suggest you to use such feature. If you need to use DirectX, you can use it in your application level, that's the better solution.
 
FYI and wish you good luck!
 
 
 
Best regards,
Ryan

Thanks for all your help.
Yes,I install directx sdk 9.0c.
maybe I should download the lastest version from svn,now,I just download it from www.packetizer.com.
 
I also try to modify the config.c to :
 
dnl MSWIN_DISPLAY    dsound,Direct Sound Support
dnl MSWIN_CHECK_FILE dsound,include\dsound.h,P_DIRECTSOUND=1
dnl MSWIN_DISPLAY    dshow, Direct Show Support
dnl MSWIN_CHECK_FILE dshow, include\DShow.h, P_DIRECTSHOW =1
dnl MSWIN_DIR_SYMBOL dsound,DIRECTX_DIR
dnl MSWIN_DIR_SYMBOL dshow, DIRECTX_DIR
 
 
Although when I compile it with Visual studio c++2003,it output "Direct Show Support",
at fact,when I compile the myphone2,
I find it donot support.
 
Thanks again.

Hi,
 
As Ryan said, you need DIRECT X SDK, not DirectX9.0c

Hi,Dear Ryan:
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?
Thanks again.

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

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!
