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! 2008-11-28 JobsGuo(Guo Huayong) Mobile：13918103120 QQ ： 360480589 MSN ： ghyhust@hotmail.com
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.

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 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.

No DirectShow code yet on sources and DirectShow being replaced by DXVA (DirectX Video Acceleration) DirectSound being replace by XNA Audio: XACT2 (Cross Audio Creation Tool
Searching in the source of PWLib and on comments on the internet, I discourage the use of DirectSound for now... 2)
Windows Vista and .Net 3.5 (WDDM drivers) fallback to software mixer until specific accelarated drivers are made by vendors
Installing 2Gb of DirectX old SDK (today is november_dx10 SDK, dx11 preview) only to have access to sound is a pain.... Other thing: adding the Error String header or Util header to the production code implies in redistribute of the dx#.dll. It is a back of the DLL Hell pain because each year 2 or 3 versions of SDK are made, many versions of dx#.dll are avaible (four versions -or more- for DX9SDK, for example fev., ago., oct., nov.) PS.: Now I remembered, really the source for PWLib can be the h323plus site, no CVS repository for that. 2008/11/28 JobsGuo(Guo Huayong) <ghyhust@126.com>
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.

Hi Guo If you are using Visual Studio 2008, almost all libs are avaible for DirectShow. Only the Null Output Video Sink, necessary for proper work of Video Sampler Grabber, need some trick to work, the trick is copy the content of the header file of Null Video to a new file and remove the COM interfaces of DirectX9 surfaces, these interfaces need another headers that only avaible on DirectX SDK. You are able to find these tricks on CodeGuru site, searching for "Video Capture" This way saves one or two gigabytes of DirectX SDK.
"...I indeed install directx 9.0c.so it can ..." :: '.so'? you are using cygwin or something like it?
Other hint: ptbuildopts.h is generated by config application, sometimes config.in file need some attention to see if a positive search rule is not overlapping a negative rule. Other times you need to 'force' the config application passing hints to it like: --enable-ipv6 or --disable-ssh Again, see config.in for the rules they are using. If you manage to compile your code after some modification, dont forget to send back to this list ;) regards. ----- Jogue RPG, alimente o lado criativo!
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!

Guo, I see what do you want. Actually, I implemented a class named CVideoInputDevice(use VFW) and override CVideoChannel to do video device enumerate and use. If you need, I can give it to you for reference.

(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!
