## Lots of new features and it still retains backward compatibility!

- Added batch mode per issue #28
- Added ALAC wrapper script per issue #28
- Bug fix for issue #29 introduced with release 1.3
- Added output and keep-file options per issue #30
- Moved option check earlier in the script and completely reworked options/arguments processing
- Added long option names
- Added debug info for system API
- Added debug info for config API
- Added multiple debug logging levels, defaults to lowest
  - Default debug level excludes the returned JSON, making it more readable and useful
- Normalized test event output
- Minor fix for error text
- Added version option
- Modified how script version is handled
   - Updated BuildImage.yml
   - Updated Dockerfile
   - Update 98-flac2mp3 init script
- Changed awk pattern match to be more robust
- Removed dedundant system command in awk script
- Updated help text
- Updated README.md
- Updated SECURITY.md

$flac2mp3_script
$flac2mp3_script Version: $flac2mp3_ver
Audio conversion script designed for use with Lidarr
Source: https://github.com/TheCaptain989/lidarr-flac2mp3
Usage:
$0 [-d] [-b <bitrate> | -v <quality> | -a \"<options>\" -e <extension>]
$0 [OPTIONS] [-b <bitrate> | -v <quality> | -a \"<options>\" -e <extension>]
$0 [OPTIONS] {-f|--file} <audio_file>
Options:
-d enable debug logging
-b <bitrate> set output quality in constant bits per second [default: 320k]
Ex: 160k, 240k, 300000
-v <quality> set variable bitrate; quality between 0-9
0 is highest quality, 9 is lowest
See https://trac.ffmpeg.org/wiki/Encode/MP3 for more details
-a \"<options>\" advanced ffmpeg options enclosed in quotes
Specified options replace all script defaults and are sent as
entered to ffmpeg for processing.
See https://ffmpeg.org/ffmpeg.html#Options for details on valid options.
WARNING: You must specify an audio codec!
WARNING: Invalid options could result in script failure!
Requires -e option to also be specified
See https://github.com/TheCaptain989/lidarr-flac2mp3 for more details
-e <extension> file extension for output file, with or without dot
Required when -a is specified!
-d, --debug [<level>] enable debug logging
Level is optional, default of 1 (low)
-b, --bitrate <bitrate> set output quality in constant bits per second
[default: 320k]
Ex: 160k, 240k, 300000
-v, --quality <quality> set variable bitrate; quality between 0-9
0 is highest quality, 9 is lowest
For more details, see:
https://trac.ffmpeg.org/wiki/Encode/MP3
-a, --advanced \"<options>\" advanced ffmpeg options enclosed in quotes
Specified options replace all script defaults
and are sent as entered to ffmpeg for
processing.
For more details on valid options, see:
https://ffmpeg.org/ffmpeg.html#Options
WARNING: You must specify an audio codec!
WARNING: Invalid options could result in script
failure!
Requires -e option to also be specified
For more details, see:
https://github.com/TheCaptain989/lidarr-flac2mp3
-e, --extension <extension> file extension for output file, with or without
dot
Required when -a is specified!
-f, --file <audio_file> the script enters batch mode, using the
specified audio file as input
WARNING: Do not use this argument when called
from Lidarr!
-o, --output <directory> specify a directory for the converted audio
file(s)
This will be created if it does not exist.
-k, --keep-file do not delete the source file or move it to the
Lidarr Recycle bin
This also disables the Lidarr rescan.
--help display this help and exit
--version display script version and exit
