Perian, open source video component Download Recently, I get a message saying “This file contains a track in the Dolby AC3 Audio (code 8192) format” while I playing my mkv video file. If the problem avoided, there will be no sound for that video. After Google(ing), I found a freeware Perian that enable the application support for additional media. In particular, for the application such as QuickTime video player.
