[MPlayer-users] [BUGREPORT] crash with -vo null on dumping PCM audio from raw DV file

[vitko]

Command

    mplayer -v capture001.dv -vc dummy -vo null -ao pcm:file=audio.wav

crashes mplayer 1.0pre7, see verbose output below. This one

    mplayer -v capture001.dv -ao pcm:file=audio.wav

(w/o "-vc dummy -vo null") works fine (but it is rather slow).

Any tips on what went wrong? (I'll try to rebuild with --enable-debug=3
and will send gdb backtrace if anyone is interested).
