XiphQT

XiphQT, the Xiph QuickTime Components, is a collection of QuickTime and Mac OS X 'plug-ins' providing support for the Xiph.Org Foundation's (http://xiph.org/) multimedia compression formats.

Building

The XiphQT source code is accompanied by a set of Xcode project files, and can be built easily using Xcode GUI or 'xcodebuild' command line tool. To build from sources source codes of a number of additional libraries need to be placed in the ./external-libs folder (see below).

The latest version of XiphQT makes use of the following libraries: ogg, vorbis, flac, speex, theora and theora-exp. Their source code can be found on http://xiph.org/ .

To build using Xcode's xcodebuild command-line tool type with the ./build-macosx as the current working directory:

> xcodebuild -target XiphQT -configuration Release

That should produce statically linked XiphQT.component bundle in the ./build-macosx/build/Release directory.

To only build decoder and importer components use type:

> xcodebuild -target 'XiphQT (decoders)' -configuration Release

Installing

The binary component bundle needs to be installed in ~/Library/Components (or /Library/Components for system-wide installation). Create the folder if it doesn't exist.

Source code organisation

./AppleSDK contains selected files from the CoreAudio SDK; these files are the base of the AudioCodec API

./CAFLAC FLAC AudioCodec files

./CASpeex Speex AudioCodec files

./CAVorbis Vorbis AudioCodec files

./OggImport Ogg QuickTime MovieImporter component files

./OggExport Ogg QuickTime Movie Data Export component files

./Theora Theora QuickTime ImageCodec component files

./common, ./utils and ./resources Functions, definition and resources shared between several components

./external-libs Source code of the external libraries should be placed here in the corresponding subfolders: ogg, speex, theora, vorbis, flac (using SVN repository all libraries except flac can be pulled automatically)

./build-macosx Xcode project files, for building for Mac OS X

./build-win32 Win32 build files
