Video : picture by picture

[Audrey]

Hello,
I want access picture by picture on video : is it possible on C# ?
Thanks

 

[Kevin Spencer]

It sure is.

Of course, *how* it's done depends on the type of "video" you're working
with.

Okay, and you're writing an application that you want to be able to pull the
individual images out of these?

In any case, you're likely to be using the Microsoft DirectX classes to do
this, along with possibly some help from the Windows Media Player ActiveX
control, although that may not be necessary. Check out the Microsoft DirectX
developer center, where you can download the latest DirectX SDK, and find
all kinds of helpful information:

I'm not sure if my last post went through. Forgive me if I'm repeating
myself. Check out the MS DirectX Developer center, in particular the latest
DirectX SDK:

I think all the DirectShow stuff was moved out of DirectX and put in the
Platform SDK though.

 

[James Park]

There's an "easy" to implement this by using the Windows Media Player
component, which can move frame by frame with something like the following:

((IWMPControls2)axWindowsMediaPlayer1.Ctlcontrols).step(1);

And to grab the image, you could use the SendKeys class to get the image
into the clipboard. I don't know if this is what you want though.

DirectShow is obsolete, but the DirectX.AudioVideoPlayBack namespace has all
the necessary functionality.

Thanks for this information.
Could you explain me why DirectShow is obsolete ?

I want access picture by picture to do a list of "screen shot" of video
on format JPEG for example.

 

[Kevin Spencer]

I can only guess why DirectShow is obsolete. Its functionality has been
replaced by other namespaces and other classes. My guess would be that
Microsoft architects decided that the newer structure was more extensible,
logical, intuitive, or (I don't know) than the older. All of the
functionality is still there; it's just id different places, arranged
differently. The SDK will tell you how to use it, and includes all the DLLs
and support for it.

Ok thanks ...
I found more information on DirectShow but on audiovideoplayback it
wasn't very easy.
So, I would like ask you if you are some documentation (how to) for
manipulate video to image file?

Thank u for your help

 

[Kevin Spencer]

I really don't Audrey. I've only used DirectSound and Direct3D.

Try the Managed DirectX newsgroup:

microsoft.public.win32.programmer.directx
