Direct. Show Wikipedia. Logo of the Direct. X Media SDK  the first time Direct. Show was distributed under its current name. Direct. Show sometimes abbreviated as DS or DShow, codename Quartz, is a multimedia framework and API produced by Microsoft for software developers to perform various operations with media files or streams. It is the replacement for Microsofts earlier Video for Windows technology. Based on the Microsoft Windows. Component Object Model COM framework, Direct.

The library includes AVI Player, AVI Logger with compression capabilities, DirectShow Video Player and Video Logger, Noise generators, Test Image generator, Video. Show provides a common interface for media across various programming languages, and is an extensible, filter based framework that can render or record media files on demand at the request of the user or developer. The Direct. Show development tools and documentation were originally distributed as part of the Direct. XSDK. 2 Currently, they are distributed as part of the Windows SDK formerly known as the Platform SDK. Microsoft plans to completely replace Direct. Show gradually with Media Foundation in future Windows versions. One reason cited by Microsoft is to provide much more robust support for content protection systems4 see digital rights management. Microsofts MSFT Becky Weiss also confirms that youll notice that working with the Media Foundation requires you to work at a slightly lower level than working with Direct. Show would have. And there are still Direct. Show features that arent yet in Media Foundation. As described in the Media Foundation article, Windows Vista and Windows 7 applications use Media Foundation instead of Direct. Show for several media related tasks.

Video Player Mfc Application Tutorial' title='Video Player Mfc Application Tutorial' />HistoryeditThe direct predecessor of Direct. Show, Active. Movie codenamed Quartz, was originally chartered to provide MPEG 1 file playback support for Windows. It was also intended as a future replacement for media processing frameworks like Video for Windows, which had never been designed to handle codecs that put video frames into a different order during the compression process, and the Media Control Interface, which had never been fully ported to a 3. COM. 1The Quartz team started with an existing project called Clockwork. Clockwork was a modular media processing framework in which semi independent components worked together to process digital media streams, and had previously been used in several projects, including the Microsoft Interactive Television MITV project and another project named Tiger. Active. Movie was announced in March 1. May 1. 99. 6, bundled with the beta version of Internet Explorer 3. In March 1. 99. 7, Microsoft announced that Active. Movie would become part of the Direct. X 5 suite of technologies, and around July started referring to it as Direct. Show, reflecting Microsofts efforts at the time to consolidate technologies that worked directly with hardware under a common naming scheme. Direct. Show became a standard component of all Windows operating systems starting with Windows 9. Windows 9. 5 by installing the latest available Direct. X redistributable. In Direct. X version 8. Direct. Show became part of the mainline distribution of the Direct. X SDK and was placed alongside other Direct. X APIs. 1. 4In October 2. Direct. Show was removed from the main Direct. X distribution and relocated to the Direct. X Extras download. In April 2. Direct. Show was removed entirely from Direct. X and moved to the Windows SDK starting with the Windows Server 2. SP1 version of the SDK. The Direct. X SDK was, however, still required to build some of the Direct. Show samples. 1. 5Since November 2. Direct. Show APIs are part of the Windows SDK. It includes several new enhancements, codecs and filter updates such as the Enhanced Video Renderer EVR and DXVA 2. Direct. X Video Acceleration. ArchitectureeditDirect. Show divides a complex multimedia task e. Each filter  which represents one stage in the processing of the data  has input andor output pins that may be used to connect the filter to other filters. The generic nature of this connection mechanism enables filters to be connected in various ways so as to implement different complex functions. To implement a specific complex task, a developer must first build a filter graph by creating instances of the required filters, and then connecting the filters together. There are three main types of filters Source filters. These provide the source streams of data. For example, reading raw bytes from any media file. Transform filters. These transform data that is provided from other filters output. For example, doing a transform such as adding text on top of video or uncompressing an MPEG frame. Renderer filters. These render the data. For example, sending audio to the sound card, drawing video on the screen or writing data to a file. During the rendering process, the filter graph searches the Windows Registry for registered filters and builds its graph of filters based on the locations provided. After this, it connects the filters together, and, at the developers request, executes i. Direct. Show filter graphs are widely used in video playback in which the filters implement functions such as file parsing, video and audio demultiplexing, decompressing and rendering as well as for video and audio recording, editing, encoding, transcoding or network transmission of media. Interactive tasks such as DVD navigation may also be controlled by Direct. Show. citation needed. Filter graph of an mp. Direct. Show sample in Graph. Edit, an application with a GUI for Direct. Show used to visually build and test filter graphs. In this picture the boxes represent filters and the grey dots appearing on the sides of the filters represent pins. In the above example, from left to right, the graph contains a source filter to read an MP3 file, stream splitter and decoder filters to parse and decode the audio, and a rendering filter to play the raw audio samples. Each filter has one or more pins that can be used to connect that filter to other filters. Every pin functions either as an output or input source for data to flow from one filter to another. Depending on the filter, data is either pulled from an input pin or pushed to an output pin in order to transfer data between filters. Each pin can only connect to one other pin and they have to agree on what kind of data they are sending. Most filters are built using a set of C classes provided in the Direct. Show SDK, called the Direct. Show Base Classes. These handle much of the creation, registration and connection logic for the filter. For the filter graph to use filters automatically, they need to be registered in a separate Direct. Show registry entry as well as being registered with COM. This registration can be managed by the Direct. Show Base Classes. However, if the application adds the filters manually, they do not need to be registered at all. Unfortunately, it is difficult to modify a graph that is already running. It is usually easier to stop the graph and create a new graph from scratch. Starting with Direct. Show 8. 0, dynamic graph building, dynamic reconnection, and filter chains were introduced to help alter the graph while it was running. However, many filter vendors ignore this feature, making graph modification problematic after a graph has begun processing. FeatureseditBy default, Direct.
