Dano is a wrapper for FFmpeg that checksums the internal file streams
A hashdeep/md5tree (but much more) for media files - kimono-koans/dano
Non-media path filtering (which can be disabled) Highly concurrent hashing (select # of threads) Several useful modes: WRITE, TEST, PRINT, DUMP, or DUPLICATES Select from multiple checksum algorithms (default: murmur3, MD5, adler32, CRC32, SHA160, SHA256, SHA512) Option to decode the stream before executing the hash function Write to xattrs or to hash file (and always read back and operate on both) dano makes it easy to find such duplicate media, based upon their internal bitstreams: For Debian-based distributions (like Ubuntu), I maintain a personal package archive, or PPA.
