2020-08-170.8.3
Introduces option --script=<script to run instead of muxing>.
On Windows <script to run instead of muxing> should be a "bat"-file otherwise a shell script, e.g.
root@root-pc MINGW32 ~/bs1770gain
# cat script.bat
@echo off
ffmpeg -hide_banner -loglevel panic -i %BS1770GAIN_SOURCE% -filter:a "volume=%BS1770GAIN_INTEGRATED_RELATIVE%dB" -y %BS1770GAIN_TARGET%

root@root-pc MINGW32 ~/bs1770gain
# cat script.sh
ffmpeg -hide_banner -loglevel panic -i ${BS1770GAIN_SOURCE} -filter:a "volume=${BS1770GAIN_INTEGRATED_RELATIVE}dB" -y ${BS1770GAIN_TARGET}

root@root-pc MINGW32 ~/bs1770gain
Please note that using "ffmpeg" is not mandatory. Here it serves as a mere example.
On Windows it is assumed that there is a command interpreter at "C:Windowssystem32cmd.exe" otherwise a shell interpreter at "/bin/sh".

Option --script might be combined with option --threads, i.e. executing the script in parallel should be possible.
Introduces option --shell=<path to interpreter>. The interpreter is assumed to provide an option "-c" for executing scripts and to require POSIX path conventions.
Option --shell might come in handy especially when youíre on Windows, using "msys2" and not very comfortable with the capabilties of "bat"-files and their syntax. Then you might prefer e.g.
bs1770gain <path to input> -o <path to output directory> --script=./script.sh --shell=/bin/sh.exe
or respectively from the Windows "cmd"-box
bs1770gain <path to input> -o <path to output directory> --script=%cd%script.sh --shell=<path to msys2 installation>usrbinsh.exe
Please note that a full path to the script as well as to the shell is required.
Fixes an issue with remuxing Alexis pointed us to and which might have been occurred under certain circumstances. Thanks a lot Alexis!
2020-07-26 0.8.2
This is a maintenence release affecting mostly the Windows builds:
Introduces the (not very useful) option --skip-scan.
Fixes a long standing bug on Windows regarding options --file=<file name>/--utf-8=<file name>/--utf-16=<file name>.
With the Windows-console, we had best experiences when setting it up to display narrow (8 bit) characters while just writing wide (16 bit) characters to it. In order to achieve this the whole program had to be transformed (re-factured.) Anyway, with German OEM installed we still donít know wether it is even possible to write say kyrillic letters to the Windows-console.
Fixes an issue on Windows which had already been slipped through some time ago, i.e. under certain circumstances option -a/--apply was not working any longer.
Fixes some minor glitches we came across.
2020-07-28: The MacOS binary release is available from AdRY's Sourceforge project.

2020-07-10 0.8.1
Jointly with AdRY the following was achieved:
Re-structuring the build process in order to allow for bundeling third party shared objects with the application (as it was already usual with the Windows releases.)
Allow for dynamically loading shared objects on MacOS.
AdRY has created a project on Sourceforge for providing MacOS binary releases. The MacOS binary release will appear a few days deferred.
2020-07-14: The MacOS binary release is available from AdRY's Sourceforge project.

2020-06-24 0.8.0
This is a special pbelkner.de welcome edition (not to say: bye, bye Sourceforge.) Hence a minor version bump!
Alexis reported the issue that on his Mac with libpthread not being installed the configure script was broken. Such a set-up was resulting in a corrupt build. Thanks a lot Alexis for letting us know!
The options regarding parallel processing have been changed slightly. Now by default from time to time thereís some sparse printing indicating that the program is still working.
2020-05-290.7.0Essentially the same as 0.7.0-&#946;4.
