Create a custom codec

[Say]

i need to create a custom codec for my application or personalize one, how?
Can i use c# for that?

Honestly? - No.

C# is "managed code" which means it is real-time interpreted by the .net framework. It is MUCH too slow for video processing, and I'm not even talking about encoding.

Also, you can't just say a 'codec'. There are many types of codecs, and I doubt you know even one method codecs can use. MPEG-2 for example works with blocks, MPEG-4 is more complex, can't explain it either.

If you're sure you want to personalize a codec, take some of the open-source projects and have a look at their source codes. They should all be C/C++ or ASM, don't expect any C# there. ;)

is there some free to use and distribuite codec?
i need to make an application that works with it so i need to make a setup that install that codec on the user pc.

Someone wrote an MPEG1/2 decoder in JAVA, so I wouldn't say that you CAN'T write codecs in managed languages. They'll just require more from your computer and the JIT compiler than codecs written in C/C++/ASM.

If you want a codec similar to xvid quality that is open source that you can distribute, you should probably look at VP3/Theora.

there are free codec to distribuite with my application?
How can i install a codec?
