The developers behind the Perian plugin for Apple QuickTime on OS X have announced that they are discontinuing the project.
The plugin enabled users to add support for multiple file formats to QuickTime without requiring a third party software.
The developers said that they would support the last version of the app for 90 days. It would then be released to the open source community.
It is not yet known if the plugin would work on QuickTime in OS X Mountain Lion. But we hope that the plugin gets adopted by the open source community and is updated in the future as well.
Users can of course download and install third party apps like VLC to get similar capabilities.
