I want to write some filteres used in avi processing soft :
virtualdub and avisynth,
I have known the filter's structure,
but I have little knowledge about graphic processing theory with vc++.
I have look through with GOOGLE but not find some guide,
Please give me some guide,
thanks.
I see that nobody's answered you yet... and I don't really know the answers either. But, I'll try to give some suggestions and make some guesses :).
Start by looking-up the AVI file format at wotsit.org. I believe that AVI is a microsoft specification, so you might try searching the microsoft site too.
I assume that you'll need to extract the desired frames from the AVI file, and convert the frames to arrays which will represent the images as bitmaps (or "pixel maps").
Both virtualdub and avisynth are open source, so you should be able to look at the source code to see how others have implimented filters.
@DougDbug :
Thanks for giving me a hand.
This is a good site, I have save it .Quote:

I have download some opensource filter prog, but it's very complex for me , some prog even include ASM statement, I think I will never study asm, it's make me headache.Quote:

I am a avi fun , my studing vc++ purpose is to write some filters, not to be a vc++ guru.
so I just want to forward in this way.
I want to continue study in college, but donn't know what course should be selected.
