Introduction
---
libsmacker is a cross-platform C library which can be used for decoding Smacker Video files produced by RAD Game Tools. Smacker Video was the king of video middleware in the 1990s, and its 256-color compressed video format was used in over 2600 software titles.
libsmacker implements the minimum feature set required from smackw32.dll to get an smk off a disk and the frames / audio into a buffer in the correct order.

libsmacker is released under a Creative Commons Attribution Non-Commercial License V2.0. This means, first, that projects using libsmacker must indicate somewhere that they use libsmacker in the code. Also: the Non-Commercial tag means exactly what it suggests: LIBSMACKER MAY NOT BE USED IN ANY COMMERCIAL PROJECT. PERIOD. Non-commercial DOES NOT mean simply "non-profit": commercial includes for-profit, but may also encompass other non-profit activites as well.
Static- or dynamic-linking against unmodified libsmacker does not automatically re-license your code. If you alter the library code (.c, .h files), your changes become a Derivative Work and are subject to the conditions outlined in the license. Unmodified redistributions of binary libsmacker in your own projects must meet the conditions of this license.

Usage
---
See the webpage for sample code and function documentation. The source package additionally includes a pair of driver programs:
* driver.c - dumps all frames of a file to a bmp/ subdirectory, and all audio as raw streams to out_*.raw files in CWD
* smk2avi.c - converts smk file(s) to AVI files - uncompressed 24-bit color and PCM audio stream.
Though the libraries are "bulletproofed" the sample apps are not: be cautious if you plan to implement in some critical environment.
