 Dolby Encoding Engine Wrapper

DDP encoding has never been so easy!

Description

• 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 is parsed from source
• an XML file will be generated for each input based on the settings
• the script utilizes thread pooling for batch encoding (all threads-1 by default)
• supports WSL path conversion for the Win version of DEE (see config)
• in case of an invalid bitrate it will pick the closest valid one
• automatic sample rate conversion using ffmpeg's soxr resampler in case of an unsupported sample rate
  • for dd/ddp unsupported rates will be converted to 48000
  • for thd unsupported rates will be converted to 48000 if source sample rate is lower than 72000, otherwise will be converted to 96000
• automatic dialnorm setting
• checks if intermediate file is already created so you can encode different formats/bitrates using a single intermediate file, for example:
  ./deew.py -f dd -b 448 -i input -k
  ./deew.py -f dd -b 640 -i input -k
  ./deew.py -f ddp -i input
• works even with video inputs (first audio will be selected)

Requirements

• ffmpeg
• ffprobe
• Dolby Encoding Engine

Installation

git clone https://github.com/pcroland/deew
cd deew
pip install -r requirements.txt

• rename config.toml.example to config.toml and edit the settings
• install your DEE (if you use WSL use the Win version for better performance)
• place your license.lic file next to the DEE binary

Usage

❯ ./deew.py --help
usage: deew.py [-h] [-v] [-i [INPUT ...]] [-o OUTPUT] [-f FORMAT] [-b BITRATE] [-m MIX] [-drc DRC] [-t THREADS] [-k] [-pl]

options:
  -h, --help                           shows this help message.
  -v, --version                        shows version.
  -i [INPUT ...], --input [INPUT ...]  audio file(s) or folder(s)
  -o OUTPUT, --output OUTPUT           output directory
                                       default: current directory
  -f FORMAT, --format FORMAT           dd/ddp/thd
                                       default: ddp
  -b BITRATE, --bitrate BITRATE        defaults:
                                       DD5.1: 640
                                       DDP5.1: 1024
                                       DDP7.1: 1536
  -m MIX, --mix MIX                    6/8
                                       specify down/upmix, only works for DDP
                                       DD will be automatically downmixed to 5.1 in case of a 7.1 source
  -drc DRC                             film_light/film_standard/music_light/music_standard/speech
                                       drc profile
                                       default: film_light
  -t THREADS, --threads THREADS        number of threads to use, only works for batch encoding,
                                       individial encodes can't be parallelized
                                       default: all threads-1
  -k, --keeptemp                       keep temp files
  -pl, --printlogos                    show all logo variants you can set in the config

Examples

./deew.py -i *thd
encode DDP

./deew.py -b 768 -i *flac
encode DDP with 768kbps

./deew.py -m 8 -i *dts
encode DDP with 7.1 upmixing

./deew.py -f dd -b 448 -t 4 -i S01
encode DD with 448kbps using 4 threads (input is a folder)

./deew.py -f thd -i *w64
encode TrueHD

./deew.py -f dd -i *dts -k
./deew.py -f ddp -i *dts
encode multiple formats/bitrates while creating the temp file just once

Todo

• pyinstaller standalone exe
• multiple progress bars (currently encoding progress is only shown for a single input, for multiple inputs the progress bar counts the encoded files)
