MediaPipe is a flexible framework to manipulate media on MacOS X. It allows you to build decoding, filtering, encoding and even streaming pipelines that correspond exactly to your needs. Additionally, if a format is not supported, or a transformation missing, it features an SDK that allows you to quickly implement the pipe you want.

HTMLZip is a utility to creating compressed HTML pages. True compression algorithm reduces files to 20%-70% of original. JavaScript is used for extracting in your browser (no third-party software).

Release 1.06 appears to have gone out in October, 2002.

The folks at UltimateZip
bill their freeware program as The Archive Program for the New Millenium, and why not? It has a full set of archive types that it supports, built in disk-spanning, skins, the works. It looks pretty good.

Release 2.7.1 shipped in September, 2002.

A set of benchmark results that compare various versions of LHA and jLHA. (jLHA is an LHA library found on the same web site.)

jLHA is a Java library that supports reading and writing of LHA archives. It attempts to use the same interface as the java.util.zip package. It looks like there was a burst of activity in the spring of 2002, not much activity since them.

Full-featured batch image processing and conversion software. Over 70 image formats are supported, and the software provides an extensive array of image enhancement, editing, and processing operations. All processing and conversion operations have numerous options that can be optionally set for maximum control. The entire application is highly customizable. AutoImager also offers complete command-line support. With over 130 configurable command-line choices, it’s easy to create batch files to perform image processing tasks which may need to be done routinely. A list of available features far too long to list here.

Chilkat Zip is an easy-to-use, royalty-free ActiveX control that empowers your applications to create/manipulate Zip archives. It can encrypt your data with the latest 256-bit AES Encryption, includes self-extracting EXE capabilities, and provides easy access to decompressed contents of individual files stored within a Zip archive. You can easily compress directly from memory buffers or strings and add multiple files with wildcarding and recursing directories.

ViXS Systems from Toronto, Ontario has announced the
XCode chip, which they say will adjust MPEG formats, bit rates, and
resolutions on the fly as data moves through an IP network. At a
minimum, this means the part can format MPEG1 to MPEG2 to MPEG4, and change resolutions from QCIF to standard to high definition and back again, depending on network bandwidth availability.

A rather terse description on SourceForge: Stream transcoder will be designed for use in relaying and converting streaming audio between various formats. MP3 and Vorbis will be supported. In Beta 4 as of September, 2002.

This library adds zip compression and decompression functionality to your program, allowing you to create and modify ZIP files in a compatible way with WinZip, PKZIP and other popular archivers. Its easy and practical interface makes the library suitable for the beginners as well as for the advanced users. The library is published under the GPL - alternate licensing needs to be arranged if you wish to use this in a commercial product.

Roman Zaritski explains the arduous processes he went through learning how to convert his simulation data to MPEG format. Short and simple, and if you have a Linux system you can probably recreate this work pretty easily.

This product is used to protect the source of your HTML pages, which it does using “three layers of encryption.” I don’t know how that works, but they do advertise that LZW compression is an optional part of the process, so they earn a spot in DataCompression.info.
