Perian 1.2 improves Snow Leopard support
The Perian developers have announced the availability of version 1.2 of their open source preference pane, sometimes abbreviated as prefpane due to their file extension (.prefpane), for Mac OS X. Perian, often called "The Swiss army knife for QuickTime" by its developers, adds support for several video formats which are not natively supported by QuickTime, allowing it to play back or convert files which would not normally be possible by default.
The maintenance release is the first major update since Apple released Mac OS X 10.6. The 1.2 update addresses a number of bugs in the popular prefpane, including an issue that would sometimes cause QuickTime Player 10 to refuse to open files and problems with subtitles. Other changes include fixes for decoding Windows Media Audio (WMA) tracks and some MKV embedded fonts which were not compatible with 10.6. The developers advise all users to update to the latest release.
More details about the release can be found in the change log. Perian 1.2 is available to download (direct download) for Mac OS X 10.4.7 or higher. Users that currently have Perian installed can use the built-in update function by selecting "Check For Updates" under the General tab of Perian's preference pane under System Preferences. Perian is released under version 2.1 of the GNU Lesser General Public License (LGPLv2.1).
