a52codec

A fork/clone of the subversion repository at http://svn.cod3r.com/a52codec for the a52codec included as part of the Perian releases. Although Perian has been retired, the source code and downloads continue to be available.

The trunk branch represents the latest code from the subversion repository. The master branch represents the version that was released with Perian 1.2.3 plus some Xcode project updates and a fix for an incorrect header (description here) generated while performing AC-3 pass through. The various perian-* tags indicate which version of the a52codec source was included with each Perian release.

If you are not using AC-3 pass through (see here) then there’s nothing for you to see here so move along and install the standard Perian 1.2.3 release.

3. Replace the /Library/Audio/Plug-Ins/Components/A52Codec.component from the Perian installation with the one you just built or downloaded
