Dolby Encoding Engine Wrapper
DDP encoding has never been so easy!
An easy to use Python wrapper that utilizes ffmpeg and DEE for Dolby certified audio encoding.
Batch encoding
Since DEE only uses 2 threads for any given encoding task, deew aims to speed up the encoding time for multiple input files by starting multiple processes simultaneously based on the CPU's thread count.
Description
Main features:
- handles Dolby's XML input fuckery in the background, giving you a proper CLI interface
- converts inputs to RF64 which DEE can use bit depth, number of channels and other infos are parsed from the source
- bit depth, number of channels and other infos are parsed from the source
- an XML file will be generated for each input based on the settings
- the script utilizes thread pooling for batch encoding (see config)
- supports WSL path conversion for the Windows version of DEE (see config)
- in case of an invalid bitrate it will pick the closest allowed one
- automatic sample rate conversion using ffmpeg's soxr resampler in case of an unsupported sample rate
- for DD/DDP/AC4 unsupported rates will be converted to 48 kHz
- for TrueHD unsupported rates will be converted to 48 kHz if source sample rate is lower than 72 kHz, otherwise will be converted to 96 kHz
- automatic channel swapping for 7.1 sources (DEE swaps Ls Rs with Lrs Rrs for some reason)
- automatic dialnorm setting
- automatically compensates for DEE's 256 sample delay (DD and DDP encoding)
- checks if intermediate file is already created so you can encode different formats/bitrates using a single intermediate file, for example:
deew -f dd -b 448 -i input -k
deew -f dd -b 640 -i input -k
deew -f ddp -i input - works even with video inputs (first audio will be selected)
- fancy terminal output using rich
- versatile delay option that supports ms, s and also frame@fps formats
- parsing delay from filenames
Get Started
deew is available for install from PyPI with pip or as standalone builds for Windows and Linux.
