I'm trying to get the lame preset used by parsing the lame tag and noticed that it's no longer possible since 3.99 (I'm using 3.99.5).
1) It writes different vbr methods for "-V 0" and "-V 0 --vbr-new" even though the help page says they should be the same
2) It no longer writes the correct preset used when encoding (in both the preset and vbr_quality fields):
lame_3.99.5_vbr_v7.mp3 {u'-V 5': ['source_mono_44k', 'source_stereo_32k', 'source_stereo_44k'], u'-V 3': ['source_mono_16k']}
For example -V7 writes vbr_quality=5 for some and vbr_quality=3 for other source files.
