OpenQuicktime aims to be a portable library for handling Apple's QuickTime(TM) popular media files on Unix-like environments. Its aim is to provide encoding, authoring and editing support as well as video playback. This library is based on an enhanced version of the Quicktime 4 Linux library. It features decoding and encoding QuickTime files, support for standard audio and video codecs (including MP3 audio) and a plug-in support so that non-open source codecs can be used with OpenQuicktime. OpenQuicktime could be used by any Unix players or encoders wanting to support the Quicktime format. OpenQuicktime is still young but is already used by some applications. The most promising application using OpenQuicktime is GStreamer.
