What is DirectShow?
Microsoft’s DirectShow, also sometimes called DS or DShow, is a proprietary multimedia framework and multimedia API (application programming interface, or a piece of software generally intended to make two or more applications to communicate and share resources with each other). Codenamed Quartz during development – and still referred to as such among Microsoft’s programmers – DirectShow is the direct successor of the now defunct Video for Windows technology, and is an excellent and reliable interface upon which various media written in an assortment of programming languages can be executed. DirectShow has garnered a warm reception from developers because its architecture is extensible, meaning it can be added or augmented by third-party additions, and filter-based that can render or record media on demand (for example play a movie, or record an audio). Developer tools to create DirectShow-related applications are released in the DirectX SDK (software development kit).
Microsoft has also released the Media Foundation line, which is intended to replace DirectShow in future Windows versions, starting from Windows Vista. This OS, and Windows 7 that came after it, uses both DirectShow and Media Foundation, depending on the task at hand.
DirectShow’s filter-based technology includes the source filter (input), transform filter (modification of media), and the renderer filter (playback, saving of media files, etc).
