Sorry, only if you are using the "old" directx is dshow.h part of directx. It's now part of the platform SDK. In either case, your configuration isn't made properly.

Things I've done wrong to get similar messages: Didn't clean ptlib / pwlib. Didn't point compiler to the proper directories (when I have multiple versions).

Hi,

I've downloaded the latest version of PTLib from SVN and in fact, in configure.ac there is a section about directshow. When I compile PTLib, configure detects DirectShow support and enabled it. But my problem is that when I try to compile Simple or MyPhone2 to make tests, both fail because they have an #include <ptlib/dshow.h>, and there is no such header file. What am I doing wrong? Where can I found that file?

BR,

Unless there is an section in configure.ac in your version of ptlib for diectshow I would not just define it. Let configure find it if both pwlib version supports it and it get detected. The original version of directshow was only for mingw however it has since been ported to VS and added to the configure.ac to autodetect support.

    Hi,

    Is it possible to have DirectShow enabled on native Windows
    simply by defining P_DIRECTSHOW in ptbuildopts.h? Is it
    necessary any other work?

Hi, Simon:

First of all, thank you for your help. I summarize my current status as follows:

1. If I download the latest version of PTLIb from SVN, builds fine (i suppose that has DirectShow support enabled for Windows native), But when I try to compile H323PLus (either the official release or the one from CVS) it gives me compile errors. 2. If I get the official release of PTLib (with support for DirectShow only for MINGW), but "patched" with the configure.ac file from the SVN, it compiles and detects and enables DirectShow. I can also compile both H323PLus (official) and Simple and MyPhone2. I've also added the vidinput_directx.* to the PTLib Static project, because they are not included by default. And also, I've removed some __MINGW__ defines to allow the DirectShow code to run in Windows native. All of this seems to work fine. But when MyPhone2 or Simple tried to open the Input Device, they cannot do it because in the method PPluginManager::GetPluginsDeviceNames(), the line PDevicePluginServiceDescriptor * descr =

(PDevicePluginServiceDescriptor *)GetServiceDescriptor(serviceName, serviceType); always return NULL. It seems that I have to do something more in order to register the DirectShow video input device driver. doesn´t it?

I know that all of this problems are due to my "hacking" of the PTLib code to "force" DirectShow support in Windows native. You said in a previous message that you planned to release an official version of PTLib with DirectShow support in Windows native "in a couple of weeks". Do you think that is better for me to wait for this official release? Are you close to release that version?

BTW, I've managed to "fix" the CVideoOutputDevice in MyPhone2 using code from PVideoOutputDevice_Window. It works fine in CIF and QCIF, but I have to fix the "PinP mode" for local video when using CIF. How could I contribute this fix?

Best retgards,

Looks like some changes in ptlib and <ptlib/dshow.h> no longer works.

Remove the line and see if the directshow video input device is loaded. Sometimes (and and for me it didn't automatically load)

If not then add. #include <ptlib/msos/ptlib/vidinput_directx.h>

which is what <ptlib/dshow.h> should be an alias for
