/* The following is a short description of the AVI file format. Please
|
|
* see the accompanying documentation for a full explanation.
|
|
*
|
|
* An AVI file is the following RIFF form:
|
|
*
|
|
* RIFF('AVI'
|
|
* LIST('hdrl'
|
|
* avih(<MainAVIHeader>)
|
|
* LIST ('strl'
|
|
* strh(<Stream header>)
|
|
* strf(<Stream format>)
|
|
* ... additional header data
|
|
* LIST('movi'
|
|
* { LIST('rec'
|
|
* SubChunk...
|
|
* )
|
|
* | SubChunk } ....
|
|
* )
|
|
* [ <AVIIndex> ]
|
|
* )
|
|
*
|
|
* The main file header specifies how many streams are present. For
|
|
* each one, there must be a stream header chunk and a stream format
|
|
* chunk, enlosed in a 'strl' LIST chunk. The 'strf' chunk contains
|
|
* type-specific format information; for a video stream, this should
|
|
* be a BITMAPINFO structure, including palette. For an audio stream,
|
|
* this should be a WAVEFORMAT (or PCMWAVEFORMAT) structure.
|
|
*
|
|
* The actual data is contained in subchunks within the 'movi' LIST
|
|
* chunk. The first two characters of each data chunk are the
|
|
* stream number with which that data is associated.
|
|
*
|
|
* Some defined chunk types:
|
|
* Video Streams:
|
|
* ##db: RGB DIB bits
|
|
* ##dc: RLE8 compressed DIB bits
|
|
* ##pc: Palette Change
|
|
*
|
|
* Audio Streams:
|
|
* ##wb: waveform audio bytes
|
|
*
|
|
* The grouping into LIST 'rec' chunks implies only that the contents of
|
|
* the chunk should be read into memory at the same time. This
|
|
* grouping is used for files specifically intended to be played from
|
|
* CD-ROM.
|
|
*
|
|
* The index chunk at the end of the file should contain one entry for
|
|
* each data chunk in the file.
|
|
*
|
|
* Limitations for the current software:
|
|
* Only one video stream and one audio stream are allowed.
|
|
* The streams must start at the beginning of the file.
|
|
*
|
|
*
|
|
* To register codec types please obtain a copy of the Multimedia
|
|
* Developer Registration Kit from:
|
|
*
|
|
* Microsoft Corporation
|
|
* Multimedia Systems Group
|
