Teddy.exe (version 1.20) fails to read mp3 files - MacOS 12.6

[steve8x8]

Using Teddy on MacOS, I seem to be unable to read mp3 files for encoding (both in VBR and CBR modes):

mono ../Teddy.exe -m encode --vbr -v -v -v -o NEW.20230121T140455 test.mp3
[Mode: encode, 96 kbps, VBR]
 Track   1 - test.mp3         [

Unfortunately I currently cannot use TeddyBench. Any hints how to further debug this (beyond -v -v -v)? Thanks in advance...

[SciLor]

This because TeddyBench uses windows specific features to encode the files. Please use the Linux fork, that uses ffmpeg for encoding.

[steve8x8]

Still getting errors (which seem to be related to the GUI, this is MacOS not Windows and not Linux) - and there seems to be no plain Teddy.exe in @AlbrechtL 's releases. I'll attempt to setup a Linux VM.

[SciLor]

I would rather try using a Windows VM, as this is the most used version.

[steve8x8]

Got a bit further (I won't touch Windows, I swear!), by adding a few settings:

export MONO_FRAMEWORK=/opt/homebrew # I'm using brew for everything missing from the OS, including `mono`
export DYLD_FALLBACK_LIBRARY_PATH=${LD_LIBRARY_PATH} # as mono doesn't seem to obey `LD_LIBRARY_PATH`

(LD_LIBRARY_PATH contains /opt/homebrew/lib) to the TeddyBench script, and installed mono-libgdiplus which was indeed missing. Now TeddyBench tells me

Unhandled Exception:
System.TypeInitializationException: The type initializer for 'System.Windows.Forms.XplatUI' threw an exception. ---> System.DllNotFoundException: libc.dylib assembly:<unknown assembly> type:<unknown type> member:(null)

(the GDIplus error is gone!). I'm now open for suggestions where to find (or how to add) libc.dylib. (Next I'll try export MONO_LOG_LEVEL=debug.)

All attempts to get TB working on Mac have failed, and I'm running out of time and ideas - switching to bailli/opus2tonie which is a pure Python solution, and looks perfect for command-line usage ... I'll watch out for new releases though.
