avifil32.dll - What is avifil32.dll?

avifil32.dll File Description:

the avifil32.dll module processes video files stored in Audio Video Interleave (AVI) format so that Windows will be able to read them.

The AVI as multimedia container format is part of Microsoft's Video for Windows technology. The audio and video data downloaded on Windows is contained in AVI format as a standard container. These audio and video data are sent to the avifil32.dll module for processing to allow audio-with-video playback. Audio and video streaming is also enabled when the avifil32.dll file is called.

The avifil32.dll file processes the audio and video data by adopting them as Resource Interchange File Format (RIFF). This involves the process of dividing data contained in a file into blocks, or chunks. The avifil32.dll file assigns each chunk with a FourCC tag. Each AVI file is considered a single chunk in a RIFF formatted file. This file is then subdivided into two mandatory chunks and one optional chunk.

The avifil32.dll file works in tandem with the msvfw32.dll file or the Video for Windows DLL. The specific functions of the avifil32.dll file are loading, reading and interrogation. On the other hand, the Video for Windows provide functions for rendering a DIB directly from memory onto a device context. The msvfw32.dll file can do this without having to create and intermediate GDI DIB section or memory device context to Blit it from. The file avifil32.dll and the msvfw32.dll file are both essential APIs used for playing AVI formatted files.

Windows 2000 and XP systems will be able to display AVIs with MPEG4 compression. Similar 32-bit systems have the appropriate codec, or the encoder/decoder software, to display a particular file format that can be supported by the avifil32.dll file. The audio and visual data processed as RIFF formatted files can be encoded or decoded by codec. When the file is created, the codec translates between raw data and compressed data format inside a chunk. The DLL avifile32.dll may then process the AVI file to carry audio and visual data inside the chunks in virtually any compression scheme, such as Motion JEPG, Editable MPEG, VDOWave, RealVideo, QPEG and MPEG-4 Video.
