Hi!
I have a big problem with my DirectShow (DirectShow.Net)/ DirectX (SlimDX) application.

It worked perfectly fine on my notebook, but when I moved application to another machine output is not right.

This is how it looks like in correct output:


And there is what i get on other machine:




DirectShow graphs looks the same:
webcam -> smart tree -> Color Space converter -> Frame Grabber -> Null Renderer.

The application simply captures the frame and set it as a texture in DirectX.

I capture frames in ARGB32 format.

Computers:

Notebook (good result)
Intel Core 2 Duo T9300
ATI Mobility Radeon HD 3650
Windows 7 Pro x64 SP1
K-Lite Mega Codec Pack 6.6.0


PC (bad result)
Intel Core 2 Quad Q8300
MSI GeForce GTS250 1GB
Windows 7 Pro x64 SP1
K-Lite Mega Codec Pack 8.4.0

Webcam:
Logitech Pro HD C910


I suspect DirectShow problem with settings, but I dont know where to look for them. Can You tell me, so I can configure PC the same as notebook and run app on that?

Thanks,
Andrew

It looks like you are making incorrect assumptions about the pitch of your D3D surface.

Thanks a lot! Thanks to You I was able to find wrong part of my code.

It seems that on notebook pitch is the same size as the stride.

When I fill texture bytes it used to be:

var data = texture.LockRectangle(0, LockFlags.None);
for (int i = 0; i < Height; i++)
{
data.Data.Write(TextureBytes, (Height - 1 - i)*Stride, Stride);
}

And the corrent version is:

var data = texture.LockRectangle(0, LockFlags.None);
for (int i = 0; i < Height; i++)
{
data.Data.Write(TextureBytes, (Height - 1 - i)*Stride, Stride);
data.Data.Position += data.Pitch - Stride;
}
