You can find them at http://ffmpeg.sf.net/ and http://mpeg4.jamby.net/, respectively more>> MS-MPEG4v2 Codec is a codec based almost exclusively on FFMpeg and DivOSX. You can find them at http://ffmpeg.sf.net/ and http://mpeg4.jamby.net/, respectively. This codec plays (flawlessly, as far as I know) video encoded in the MS-MPEG4v2 codec. To install, put it in /Library/Quicktime. It will not function on Mac OS 9 or earlier. If you are trying to play an AVI file with MP3 audio, and you probably are, you must go to http://doctor.3ivx.com/ and get DivX Doctor; Quicktime has a lot of trouble playing MP3 audio in AVI files. Just use DivX Doctor on your MS-MPEG4v2 AVIs as you would DivX AVIs.
Mac OS X 10.0 or later, QuickTime 6.0 or later.
AC3 Codec 0.4
AC3 Codec - Play AC3 audio in AVI files more>>
First you need DivX 5.1 which correctly load the AVI file into QuickTime. Once you have DivX 5.1 installed, if you are on MacOS X, drop "AC3 Codec.component" into /Library/QuickTime, or if you are on MacOS 8.x/9.x, drop "AC3 Codec" into your Extensions folder and restart.
Thats it ! Now open an AVI file that has AC3 audio, and play !
ENJOY !
A52 Codec 1.5
A52 Codec allows playback of A52/AC-3 audio in CoreAudio apps. more>>
It is a CoreAudio component that can decode stereo and 5.1 surround sound from A52 and AC-3 audio.
This type of audio is often found in DVD movies.
A52 codec is a simple wrapper around the open-source library liba52. The wrapper merely adapts the library to Apples CoreAudio framework. It also handles getting some information from the A52 stream and setting it, so other units farther down the line can be well informed.
Technical Information About A52 Codec
We have successfully been able to play 2-channel AC-3 files with Apple-provided software. Apples AC-3 AudioFile component has a bug which makes it unable to detect LFE channels, so applications will need to provide their own stream loading services for full decoding. The media-encoding application 3ivx Crush utilizes this component fully to successfully decode full 5.1 channel data.
The filter is constrained to decoding either stereo or full 5.1 sound. Applications like 3ivx Crush will then encode this using QuickTime 7 for full fidelity sound.

CODEC 1.0.1
CODEC - 4th Dimension component which provides MD5 digest creation routines more>>
CODEC is a subset of functions available already in the BASh 4D component.
In keeping with the tradition of offering high quality developer tools and services, Deep Sky Technologies, Inc., has made the CODEC component available for free to the developer community.
The CODEC component consists of two methods for the creation of MD5 digests:
CODEC_Encode_MD5_x creates a properly formatted MD5 digest directly from a supplied 4D text value.
CODEC_Encode_MD5_z creates a properly formatted MD5 digest directly from a referenced 4D BLOB value.
Both methods are immediately available for use upon installing the CODEC component. No plugins, external documents, or initialization is needed to begin using the methods. And, all of the code in the CODEC component is set up to handle even the most stringent 4D Compiler settings (e.g. All Variables are Typed).

iMkvExtract 2.0
A software tool that helps you extract Matroska .Mkv files more>> A software tool that helps you extract Matroska .Mkv files
Matroska is the extensible open standard Audio/Video container. Matroska is usually found as .mkv files (matroska video) and .mka files (matroska audio).
Matroska aims to become THE standard of multimedia container formats. It was derived from a project called MCF, but differentiates from it significantly because it is based on EBML (Extensible Binary Meta Language), a binary derivative of XML. EBML enables the Matroska Development Team to gain significant advantages in terms of future format extensibility, without breaking file support in old parsers.
iMkvExtract will extract Matroska video files and file parts from a folder of your choosing.
