Hashes actual media streams via ffmpeg, ensuring checksums remain valid after metadata changes or container swaps, as shown in the Sample.mkv to test2.mp4 conversion example.

Stores checksums in extended file attributes (xattrs) or separate hash files, with automatic reading from both, offering multiple persistence options without locking users into a single method.

Identifies duplicate media files based on identical internal bitstreams, useful for cleaning up libraries where files have different containers or tags, as demonstrated with FLAC copies.

Imports existing checksums from FLAC files and verifies them, seamlessly extending FLAC's built-in checksumming to other formats like ALAC or MP4.
