This app allows macOS Finder to display thumbnails/cover art, QuickLook previews, and metadata for most types of audio and video files.
QuickLook, AVFoundation and Spotlight understand a limited number of media files - mostly only MPEG audio and video codecs within MPEG container files. This app adds support for wide range of other codecs and "non-native" media file types, including:
- File formats: Matroska (
.mka,.mkv), WebM (.webm), Windows Media (.wma,.wmv), Ogg Video (.ogm,.ogv), AVI (partial support) (.avi), Flash Video (.flv,.f4v), Real Media (.ra,.rm,.rv), SMPTE (.gxf,.mxf) - Audio codecs: Vorbis, Windows Media Audio, WavPak, ATRAC, etc.
- Video codecs: VP6, VP8, VP9, AV1, VVC/H.266, Theora, Sorenson 1 & 3, Cinepak, Flash, Real Video, Intel Indeo, etc.
The app contains a Spotlight extension that adds support for non-native file formats, and two Media Extensions that add support to AVFoundation for non-native file formats and video codecs. (Long-time Mac users may remember Perian which performed a similar function with the QuickTime framework before QuickTime was replaced by AVFoundation).
