A frame grabber is an electronic device that captures (i.e., "grabs") individual, digital still frames from an analog video signal or a digital video stream. It is usually employed as a component of a computer vision system, in which video frames are captured in digital form and then displayed, stored, transmitted, analyzed, or combinations of ...
WIA is a very significant superset of the support for digital still imaging drivers that was provided by the Still Image Architecture (STI) in Windows 98.Whereas STI only provided a low-level interface for doing basic transfers of data to and from the device (as well as the invocation of an image scan process on the Windows machine through the external device), WIA provides a framework through ...
DirectSound also provides a means to capture sounds from a microphone or other input and controlling capture effects during audio capture. [2] After many years of development, today DirectSound is a mature API, and supplies many other useful capabilities, such as the ability to play multichannel sounds at high resolution. While DirectSound was ...

When the sound card uses a custom driver for use with the system supplied port class driver PortCls.sys or implements a mini-driver for use with the streaming class driver, applications can bypass the KMixer completely and use the kernel streaming interfaces instead to directly interact with audio driver and reduce latency. Windows 98 includes ...
The frametimes benchmark feature (logging of individual frame render times) gained attention in 2013 on computer review sites in debate about micro stuttering in games. [2] On Windows Vista and Windows 7, the desktop can be captured if Windows Aero is enabled. Windows 8 game capture works, but not desktop capture as of version 3.5.99. [3]
Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression.It was designed to be the successor of the MP3 format and generally achieves higher sound quality than MP3 at the same bit rate.
Slide shows are prepared from a sequence of AVC still frames, and can be accompanied by a background audio track. Subtitles are used in some camcorders to timestamp the recordings. Audio, video, subtitle, and ancillary streams are multiplexed into an MPEG transport stream and stored on media as binary files.
