What are AVS scripts and DirectShow filters? Is DirectShow a component of the DirectX package?

[mats.hogberg]

AVS scripts are text files that is used by AviSynth for processing video files.
DirectShow is a component of DirectX, yes, and a DirectShow filter is used for decoding a particular media file type, like XviD or AC3 or...

Directshow filters are also used for encoding, parsing, resizing, rendering, etc. They aren't just for decoding.

source filter connects to parser filter which connects to a decoder filter which connects to the renderer. You could also have denoising, etc. filters and you have directvobsub for rendering subtitles.

so that means codecs are filters? For example, when i install the DivX codec, i'm actually installing a filter? MPC allows you to choose the filters to be loaded, dont Windows Media Player etc. allow this?

[mats.hogberg]

You're installing a DirectShow filter among other things yes.
WMP is for illiterates, whose computer knowledge reaches to the level of pressing the ON/OFF button. A common MS philosophy

The codec part of DivX is VfW. The directshow filter is a decoder only.
