[MPlayer-users] Unwanted warnings from ffmpeg/libavformat/utils.c despite "-msglevel all=-1"

[Ilja Sekler]

Hello,

when playing various flash videos in MPlayer with -really-quiet or
-msglevel all=-1 options, the only text which still gets printed to the
console is a warning

[flv @ 0xa879dc0] Estimating duration from bitrate, this may be inaccurate

from ffmpeg/libavformat/utils.c:2025. How could I suppress this small
annoyance without adding 2>/dev/null to the command line?

MPlayer r33953.

Thanks,
