21.01

• Thanks to New York Public Library (NYPL) for their vision and support on this release
• Thanks to British Film Institute (BFI) for their extensive testing
• Reversibility checking: an option to check after encoding to ensure that the decoding of a RAWcooked file is fully reversible (--check)
• Reversibility checking: an option to embed checksums of the input files to enable the possibility of later reversibility integrity checks without requiring access to the original input files (--hash)
• Conformance checking: an option to to perform a selection of DPX implementation checks (--conch), more to come
• Coherency checking: an option to check e.g. that audio duration is same as video duration (--coherency, by default)
• A new requirement when encoding DPX with padding bits to specify user preferences for the evaluation of padding bits (--check-padding or --no-check-padding) as some DPX files use padding bits for unstandardized purposes.
• An option to offer extra information about the content of the reversibility data (--info)
• Perform --info --check --hash --conch --coherency --check-padding --encode in a single option (--all)
• Support additional post-encoding coherency checks, such as a quick check of the resulting compressed file in order to be sure that FFmpeg correctly finished the encoding.
• Fix reversibility issues if DPX header does not have the same size in all files
• Support of more DPX/TIFF/WAV/AIFF flavors and features
