[MPlayer-users] MPlayer doesn't dump subtitles

[amadeo]

Dumping subtitles doesn't work. Using the following command line no subtitles
dump is created:

mplayer /dev/zero -rawvideo pal:fps=23.976 -demuxer rawvideo -vc null -vo null
-noframedrop -nosound -benchmark -sub a.sub -dumpsrtsub

The above command (from he manpage, I just added the -nosound option) should
dump the subtitle to a dumpsub.srt file in the current directory, but no dump
file is created.
