File Extension DRV

File type: Device Driver File

About the DRV file type:

Invalid file associations could be the result of underlying issues within your Windows PC. It is highly recommended to scan your PC for invalid registry entries, unused processes and other slowdown issues.

The DRV file extension is related to a device driver file which is responsible for the establishment of a communication foundation between the computer system and the supported hardware component. This software allows the computer system to maximize the potentials of the device by making sure that the correct commands are sent by the calling program to the accessed device. This format file is commonly associated with the Video for Windows application which delivers video data processing capability to different programs. This application was launched by Microsoft under its 16-bit Windows Operating System platform with majority of its feature sets being superseded by the DirectX technology with the emergence of 32- and 64-bit computing process. The original version of this program supported by the DRV file extension was limited to a maximum resolution of 320 by 240 pixels with a maximum of 30 frames per second framerate. In July 1996, the Video for Windows implementation was replaced by the ActiveMovie which was a COM-based deployment of a similar technology. Subsequently, ActiveMovie became a component of the DirectX 5 technology suite and was later referred to as the DirectShow.

The DRV file extension can function as stream and file handlers providing consistent interfaces for an application tasked with controlling multimedia content. These handlers cover Operating System video usage along with waveform audio data saved in an AVI (Audio-Video Interleave) format. Handlers can be written to provide applications with a process of writing or accessing multimedia data from another source like in the case of a proprietary format that can be played back without its native software. Another supported feature is the AVIFile that allows access to the time-based data of RIFF (Resource Information File Format) like waveform-audio and AVI format files. This feature manages RIFF formats allowing the user to navigate through its architecture. The DRV file extension supports the compression and decompression of video data including the drawing of the rendered information directly to the display screen. It allows the incorporation of video capture technologies into various applications by invoking the AVICap Window Class.
