Can you share with us what you specificaly want to do with DirectShow?
Just to note: I've built a DirectShow C++ VCL that we hope to offer the
community soon, that provides playback (music, video).  We're contemplating
moving it to Delphi for wider usage, but if there's community interest in
the C++ VCL  we might offer that first.  If you're trying to do it yourself,
then be sure you create the proper Borland LIB files from the DirectX DLLs
(e.g. strmiids.lib).

Hi Paul,

I think what Helios is asking, and also what I am trying to figure out is: What
are the steps necessary to setup the DirectX SDK to work with Borland Builder?
Unless I am misunderstanding something (which is very possible ;-)), the
programmer needs to setup the DirectX SDK to be able to use DirectShow.

Some other questions:
1.  Once you have a set of the DirectX files that have been implib'ed (like the
ones available from the Borland website), what are you supposed to do with
them?  Which directory are they stored in, and how does the compilier need to be
set to recognize these new library files?

2.  When making the project, what files (if any) need to be added to the project
beyond the regular set of .h, .cpp, and .dfm files?

I'm planning on using DirectShow to capture video images from our customer's
video cameras.  They want the ability to capture still images, series of still
images, or to create mpeg files.

Thanks for any help you can provide,
Mike Goldweber

Hi all,
first of all here is a link that provides the DirectShow base classes for
CBuilder and other material:

http://slydiman.compass.com.ru/eng/mmedia/mmedia.htm


I have the libs in a different folder than CBuilder\lib. Setting the lib
path to this folder never worked for me, BCB didn't seem to find the libs.
So when the linker gets me unresolved externals I know I need to add one of
these libs to the project by hand!
Project->Add To Project   etc.
Sometimes I had unresolved externals because of GUIDs or CLSIDs but I did
not know which lib contains them. In that case I did a text search with the
explorer search dialog.

Regarding the header files: CBuilder ships with some DirectX headers, but
you need the headers compatible with your libs. Since I ordered the DirectX
CD from MS I had newer headers than those that came with BCB. I removed all
DirectX headers from CBuilder\include and copied my new headers there
instead. Since this folder is in the path by default, there should nothing
more to do!

regards,
Nick

Hi Nick,

First, thanks for your help with getting this set up.  I really appreciate it.

I've done what you and the slydiman website said to do.  Right now I'm getting
the following errors for the strmif.h and control.h file:

[C++ Error] strmif.h(860): E2257 , expected.:
        typedef DWORD_PTR HSEMAPHORE;
[C++ Error] strmif.h(2578): E2303 Type name expected.
        /* [in] */ HSEMAPHORE hSemaphore,


Have you ever seen anything like this?  Any ideas why this error would pop up
from the SDK's header file?  If it matters, I'm running Builder 4.

Thanks again,
Mike Goldweber

Sorry, havn't seen this before, but it looks like DWORD_PTR  is unknown to
the compiler. DWORD_PTR should be something like
#define DWORD_PTR DWORD*
Either try to find the DWORD_PTR declaration (or #define) in the BCB header
files or add the above line to strmif.h for a first try. The second error
should be a follow up from the first.
