DirectShow is an architecture designed for filtering and managing media streams. It isolates applications from the complexities of hardware transport, data formats, and compression.

DirectShow is an extensible, filter-based architecture built on the Component Object Model (COM). It isolates applications from the underlying complexities of hardware transport, data compression, and device drivers. Instead of writing unique code for every camera or video card on the market, developers write to the DirectShow API, and Windows handles the communication.
