[MPlayer-users] Mplayer's Ncurse's OSD Display Scrolls Metadata

[roger]

My application updates streamed ogg metadata every so often and I
noticed mplayer does not use ncurses "cursor up" with each outputted
"Demuxer info line".

Basically, what should happen, for each "Demuxer info" printed via osd
(mplayer's implementation of the ncurses lib), a "cursor up" should be
issued, and probably along with a "line clear" should also be issued
with each one.

Doing this should stop the scroll effect I'm seeing here:

AO: [oss] 22050Hz 1ch s16le (2 bytes per sample)
Video: no video
Starting playback...
Demuxer info Album changed to Album_Name
Demuxer info Artist changed to New_Artist
Demuxer info Name changed to
Demuxer info Album changed to Album_Name%
Demuxer info Artist changed to Artist_One
Demuxer info Name changed to Artist_Name
Demuxer info Album changed to Album_Name
Demuxer info Artist changed to 
Demuxer info Name changed to 
Demuxer info Album changed to Album_Name%
Demuxer info Artist changed to New_Artist
Demuxer info Name changed to New_Name
Demuxer info Album changed to Album_Name
Demuxer info Artist changed to New_Artist
Demuxer info Name changed to
Demuxer info Album changed to Album_Name%
Demuxer info Artist changed to Artist_One
Demuxer info Name changed to New_Name
Demuxer info Album changed to Album_Name
Demuxer info Artist changed to New_Artist
Demuxer info Name changed to
Demuxer info Album changed to Album_Name 20%
Demuxer info Artist changed to New_Artist
Demuxer info Name changed to New_Name
Demuxer info Album changed to Album_Name
Demuxer info Artist changed to New_Artist
Demuxer info Name changed to
Demuxer info Album changed to Album_Name 18%
Demuxer info Artist changed to Artist_One
Demuxer info Name changed to Artist_Name
Demuxer info Album changed to Album_Name
Demuxer info Artist changed to New_Artist

On second thought, maybe it's a feature to see the history of what has
been played?  But if ncurses (mplayer's osd) is being used, shouldn't
the display remain uniform and erase the history to prevent scrolling
and the scroll effect employed when ncurses isn't used?
