When writing console applications (commandline programs) it is possible to access AviSynth in two ways. Read more about the Internal Functions in AviSynth. See more information about Color spaces and Working with Images. There are several different Colorspaces in AviSynth.
There are several ways to make 2.6 plugins (plugins compiled with plugin api v5 or higher) also work with AviSynth 2.5. So when processing a clip (with say color format YV16) with a 2.5 plugin you will get a messed up clip at best, and a crash at worst, since YV16 is not supported in the v3 api. One of the features of AviSynth 2.6 is that 2.5 plugins (plugins compiled with plugin api v3) can still be used in AviSynth 2.6, although you need to make sure you use it properly since it doesn't know about the new features in AviSynth 2.6.
You can also browse various topics on Assembler Optimizing. The example explains a few things how source filters work.

See Non-clip sample how to create runtime AviSynth functions. One thing not covered in the examples, is how to change frame size in a filter. Merge (using the C API) merges two clips using a weight.SimpleSample draws a variable sized square in the middle of the screen.InvertNeg (or InvertNeg using the C API) produces a photo-negative of the input clip.All plugins use the C++ API unless stated otherwise. We will start by writing some simple plugins to show you the basics.
