How to create my own filter?

[jamesbond2000]

I have a code that treats a video and I have to implement it in a filter which will be used in a capture graph (using DirectShow library with C++).
Actually, I tried to use the DirectMedia Object but the sdk help doesn't give enough information.
Does someone knows if there is a complete tutorial that explain how to create my own filter using the DMO or not?
Thank you very much if you can help me!

Iam looking for the same, hey james I am not able to find the SDK for Microsoft Media. can u you are any one give me the DirectX Media SDK link or resource from where I can download it and start programing. I will appreciate if you inform it to me at brcraju@anion.com

The DirectX SDK for building DirectShow filters, programming with Direct3D...(and also create DMOs) can be freely downloaded from the microsoft website, at

http://www.microsoft.com,

on their download page. Simply search "DirectX+SDK+Doaxnload" on their site and you'll find it.
you also need Visual C++ (which is not free !) or another compatible compiler...(The Right choice is ... Visual C++, of course)
Good Luck!

PS : Do you know the answer to my first question
ie : how to build my own direct show filter (with or without using DMOs ???)
Thanks.

Hey James,

For your first question, Direct Media has got its own development kit, Its different from the DirectX. You have to get the development kit and then you can write your own code.
Here is the link which explains you

I suppose you can not write the filter with the DirectMedia objects but you can write your own filters with the DirectShow.

Here is the starting point of writing your own filters using DirectShow..

I suppose you have got the answer.

Regarding your answer Microsoft has not placed Microsoft DirectX Media Development kit. while we can found DirectX 8.1 is advanced which doesn't include Media development.

This DirecX Media Development Kit is found with the DirectX CD for which we need to buy from microsoft.

If you have any link which can give me Media Development kit not the DirectX 8.1.

Thanks
