Clip info: Title: As Long as You Love Me Artist: Backstreet Boys Album: The Hits: Chapter One [Canada Year: 2001 Comment: Track: 3 Genre: Dance ========================================================================== Forced audio codec: mad Opening audio decoder: [libmad] libmad mpeg audio decoder AUDIO: 48000 Hz, 2 ch, s16le, 320.0 kbit/20.83% (ratio: 40000->192000) Selected audio codec: [mad] afm: libmad (libMAD MPEG layer 1-2-3) ========================================================================== AO: [alsa] 44100Hz 2ch s16le (2 bytes per sample) !!!! Here while wait a long time, then play the music !!!! And then two mplayer processes run: $ ps 658 root 10192 S < mplayer -ao alsa -af volume=-5 -softvol -softvol-max 660 root 9808 S < mplayer -ao alsa -af volume=-5 -softvol -softvol-max Why there's two mplayer processes run if I run with "alsa" ? And I used -srate 48000 before, but the effect is also bad. Can you tell me which command I can use to play this music for better effect and DO NOT need wait a long time or setup double processes? Thanks B.R Kermit
