Re: Quick DirectShow question

Tech-Archive recommends: Fix windows errors by optimizing your registry

Andrew,

I don't like this example, personally. I think you would be better
using the ISampleGrabber interface and hooking into the video stream. For
AVI files, these samples ^should^ be in Bitmap format.

There is a library called DirectShow.NET, which has a good number of the
interfaces for DirectShow defined in a .NET assembly. You can use these to
access the render graph and insert your filter.

Here is a link to a good example of how to do this:

Hope this helps.

Hi,

I'm trying to use direct show to grab arbitrary frames from a DV .avi.

I'm using the PlayWnd code from this example:
http://www.codeproject.com/cs/media/directshownet.asp

Currently an IGraphBuiler is cast to an IVideoWindow, which is passed the
Handle of a picturebox to display the video in.

How can I grab the video directly into a bitmap object?


Thanks

Andrew
