From 9e1b33904a7752720eb6e81b3444f44967c5309c Mon Sep 17 00:00:00 2001 From: Nicko98 <39709875+Nicko98@users.noreply.github.com> Date: Tue, 9 Feb 2021 20:00:11 +0100 Subject: [PATCH] Added different loglevels I added different loglevels and (for loglevel 0 and 1) a progress bar for chapter splitting. 0 = show progress only, chapter splitting shown as progress bar 1 (default) = fewer information, chapter splitting shown as progress bar 2 = as it has been up until now 3 = debug mode --- AAXtoMP3 | 129 ++++++++++++++++++++++++++++++++++++++++++++----------- 1 file changed, 105 insertions(+), 24 deletions(-) diff --git a/AAXtoMP3 b/AAXtoMP3 index fa85260..f642ac0 100755 --- a/AAXtoMP3 +++ b/AAXtoMP3 @@ -5,7 +5,7 @@ # Command Line Options # Usage Synopsis. -usage=$'\nUsage: AAXtoMP3 [--flac] [--aac] [--opus ] [--single] [--level ]\n[--chaptered] [-e:mp3] [-e:m4a] [-e:m4b] [--authcode ] [--no-clobber]\n[--target_dir ] [--complete_dir ] [--validate]\n[--continue ]{FILES}\n' +usage=$'\nUsage: AAXtoMP3 [--flac] [--aac] [--opus ] [--single] [--level ]\n[--chaptered] [-e:mp3] [-e:m4a] [-e:m4b] [--authcode ] [--no-clobber]\n[--target_dir ] [--complete_dir ] [--validate]\n[--continue ]{FILES} [--loglevel ]\n' codec=libmp3lame # Default encoder. extension=mp3 # Default encoder extension. level=-1 # Compression level.
