/* aviffmt.h
|
|
*
|
|
* This header file describes the AVI File Format.
|
|
*
|
|
* Initial version: David Maymudes 1/7/91, based heavily on EricLe's avi0.h
|
|
* Last updated: David Maymudes 12/5/91.
|
|
*
|
|
* Prerequisites: <windows.h>, <mmsystem.h>
|
|
*
|
|
* An AVI file is the following RIFF form:
|
|
*
|
|
* RIFF('AVI'
|
|
* LIST('hdrl')
|
|
* hdra(<AVIFileHdr>)
|
|
* dibh(<BITMAPINFO>)
|
|
* [ wavf(<WAVEFORMAT>) ]
|
|
* [ vidc(<COMPRESSIONINFO>) ]
|
|
* [ audc(<COMPRESSIONINFO>) ]
|
|
* [ JUNK(<padding>) ]
|
|
* LIST('movi'
|
|
* { LIST('rec'
|
|
* SubChunk...
|
|
* )
|
|
* | SubChunk } ....
|
|
* )
|
|
* [ <AVIIndex> ]
|
|
* )
|
|
*
|
|
* SubChunk = { dibh(<AVI DIB header>)
|
|
* | dibb(<AVI DIB bits>)
|
|
* | dibc(<AVI compressed DIB bits>)
|
|
* | palc(<AVI Palette Change>)
|
|
* | wavb(<AVI WAVE bytes>)
|
|
* | wavs(<AVI Silence record>)
|
|
* | midi(<MIDI data>)
|
|
* | additonal custom chunks }
|
|
*
|
|
* !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
|
|
* We need a better description of the AVI file header here.
|
|
* !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
|
|
*
|
|
*
|
|
* 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 only necessary for interleaved files.
|
|
*
|
|
* For loading efficiency, the beginning of each LIST 'rec' chunk may
|
|
* be aligned on a 2K boundary. (Actually, the beginning of the LIST
|
|
* chunk should be 12 bytes before a 2K boundary, so that the data chunks
|
|
* inside the LIST chunk are aligned.)
|
|
*
|
|
* If the AVI file is being played from CD-ROM in, it is recommended that
|
|
* the file be padded.
|
|
*
|
|
*
|
|
* Limitations for the Alpha release:
|
|
* If the AVI file has audio, each record LIST must contain exactly
|
|
* one audio chunk, which must be the first chunk.
|
|
* Each record must contain exactly one video chunk (possibly preceded
|
|
* by one or more palette change chunks).
|
|
* No wave format or DIB header chunks may occur outside of the header.
