IMediaSeeking and windowless VMR9
Thu, 29 Nov 2007 08:24:27 -0800 (PST)
Hello everyone,
I'm having a problem with VMR9, windowless mode.
It looks like seeking the graph does not update the current image
properly.
This occurs immediately after IMediaControl::Pause() or simply after
calling IMediaSeeking::SetPositions(...).
The poster image does not correspond to the cur ...

Hello all,
I wish to use the VS2005 debugger to step from managed C# code into
unmanaged C++ code.
I have reproduced my situation in a simple example.
From the DirectX Sample Browser (DirectX SDK August 2007), I installed the

Directshow IVideoWindow.MessageDrain does not handle events properly
Wed, 21 Nov 2007 18:38:53 -0800 (PST)
Hello,

object. I am upgrading VB6 code to VB .NET and setting the message
drain to the handle doesn't seem to be working, as form clicks are not
being detected. The IVideoWindow is directly on the form, not on a
picturebox. Below is my code:

Wed, 21 Nov 2007 08:10:43 -0800 (PST)
Hi,
I have the following problem. I'm trying to build a DES timeline and
to have all my timeline clips with rounded to frame boundry times.
MediaSeeking::GetCurrentPosition() always returns an accurate time
based on the current clip's group's FPS. So because of this fact i'm
using IAMTimelineObj::FixTimes() ...

I've got seams appearing between surfaces when using multipass
rendering, how to stop this?
Sat, 17 Nov 2007 04:59:58 -0800 (PST)
Hi,
I do a basic ambient lighting pass (but I've currently got this
returning 0.0f for no lighting), and then I re-render my scene once
for each light source. This is blended with whatever is already
onscreen. After rendering just the first light (on top of the 0.0f,
i.e. nothing) I get seams showing where ...

is this frame-rate drop anything to worry about?
Wed, 14 Nov 2007 01:39:15 -0000
Hi,
My 3D engine written in VB .Net and with Managed DirectX gets between
255 to 270 fps when there is nothing to render, when I render a sky
box this drops to about 140fps. My skybox is rendered with
DrawIndexedPrimitives and consists of only 24 vertices and 36 indices
(12 faces altogether). The vertex buf ...

Using IMediaSeek with external devices
Fri, 9 Nov 2007 20:03:28 -0300
Hi, I'm developing a remote control for a miniDV camcoder and I could
implement almost everything I need... but cannot put IMediaSeek to work...
I saw some examples on the web all using digital media (wmv / avi / etc),
so, in these codes I found that people bind the IMediaSeek interface to an
instance of IG ...

computetangentframe gives "error in the application" all the time...
Wed, 07 Nov 2007 01:57:10 -0000
Hi,
I'm trying to generate the binormals/tangents for a .x mesh using the
ComputeTangentFrame method. I have cloned my mesh to use my own vertex
format that includes the binormal and tangent (are there any rules
specifying where in the declaration they should be?) but all I get is
an "error in the applicati ...
