Question

DirectShow Redistributable issue, program crashes

Asked by: Daeljan

I have a working application that uses DirectShow to manipulate a webcam.

The software module that directly uses DirectShow is written in C++ (managed dll). The rest of the application is .NET, written in C#. I am not using any 3rd party wrapper for DirectShow or DirectX, and my software is based on examples that come with the Platform SDK for Windows Server 2003 R2 (this is the correct release for Windows XP - the name is just misleading).

When I moved it from a development machine to a clean workstation, I installed software from the folder:
C:\Program Files\Microsoft DirectX SDK (June 2007)\Redist

...and similarly followed directions to install the redist from the patform SDK (this involves having to download from Microsoft to the workstation).
C:\Program Files\Microsoft Platform SDK for Windows Server 2003 R2\redist

So, a couple of issues really:

*) Instead of having to download from the MS website on the client machine, I would prefer to include the actual redist files, but I can't find them available for download anywhere.

*) After installing the redist for DirectX and DirectShow, the application still doesn't run! It crashes with the exception System.IO.FileLoadException

This would indicate that there is a component missing somewhere, or perhaps there is a path problem.
If I then install VS 2005 on the workstation, compile and run the software in order to debug it, then it all works!

I'm new to DirectShow and DirectX, and I'm assuming that the solution is simple as the software is written and proven to work in the development environment...

Many thanks.

jkr, I have the DirectX files already.

What I am confused about is that DirectShow was moved from DirectX to the Platform SDK which has its own redist, therefore the DirectX redist doesn't contain the DirectShow. It's specifically the DirectShow redist that I cant find.

Hi Merete,

Yes, the .NET framework is installed: 1.0, 1.1, 2.0

A bit more information:

When I said that the application was crashing, this was the debug build. I have since tried a release build and this works ok on the clean machine. I don't know if there is something different about VS2005 with regard to debug builds, but in the past it was possible to run them outside of the development environment.

So for the moment, there is a light at the end of the tunnel although it's a murky one. And the DirectShow Redist files are still a mystery...

 

by: DaeljanPosted on 2007-08-29 at 03:24:45ID: 19789891

Even more info:

Now that I have had it working on a clean machine, I tried installing it on another clean machine, but only installing the DirectX redist, and it worked.

So, can anyone explain to me:

What the Platform SDK redist is for?
Why was DirectShow moved to the Platform SDK, but the redist stays in the DirectX one?
It doesn't seem very well organised to me...

I'm still non the wiser as to why the debug build didn't work out. I'm splitting the points btw as you both help in pointing me in the right direction.

I am just a small pebble in this programming arena but I do read a lot.
Directx has many secrets, especially since the conception of xpsp2,  and now VIISTA all new video cards have their own directx  and if not installed correctly can cause major problems with windows versions of directx.
Its very confusing to say the least.

Maybe part of MS products to control everything. If you have peeked at Vista and the server experience user experience you'll get an idea of the security changes.
Java/ activx/ flash /scripting / anything to do with the internet since MS does own all the ip addresses of A is it?
Its all about keeping the piracy under control. And the hackers out.
What the Platform SDK redist is for?

Why was DirectShow moved to the Platform SDK
The DirectX SDK
As of August 2007 the DirectX SDK contains the following components:

Update: DirectShow is no longer a part of the DirectX SDK it has now moved into the Platform SDK.
