mkvextract 31.0.0 does not do anything
mkvextract from mkvtoolnix-31.0.0 does not work:
mkvextract file.mkv tracks 1:subtitles.sup
Error: Nothing to do.
the same command from mkvtoolnix-30.1.0 works correctly:
mkvextract file.mkv tracks 1:subtitles.sup
Extracting track 1 with the CodecID 'S_HDMV/PGS' to the file 'subtitles.sup'. Container format: SUP
Progress: 100%
It does not matter which files/tracks I choose.
This is mkvtoolnix on macOS built manually from PkgSrc.org.
Please, help.
