My script, but audio is corrupted at random durring playback (HTC Magic):

#!/bin/bash

BITRATE="600"
FPS="24000/1001"
FILE="movie.mkv"

[ -e /tmp/video.mp4 ] || mkfifo /tmp/video.y4m

[ -e /tmp/video.mp4 ] || mplayer -fps $(echo "$FPS $FILE")\
  -sws 10\
  -vf-add hqdn3d,scale=480:-10,harddup\
  -correct-pts -endpos 60 -benchmark\
  -ass\
  -ass-force-style 
PlayResX=480,PlayResY=320,MarginV=25,MarginRight=50,MarginLeft=50\
  -ass-font-scale 2 -subpos 50\
  -sub subtitle.srt\
  -vo yuv4mpeg:file=/tmp/video.y4m\
  -ao pcm:fast:waveheader:file=/tmp/audio-raw.wav\
  1&>/dev/null &

[ -e /tmp/video.mp4 ] || time x264 --profile baseline --tune fastdecode 
--keyint 60 --min-keyint 15 --bitrate $(echo $BITRATE)\
  --level 3.1 --sar 1:1 --threads 3 --pass 1\
  --vbv-maxrate $(echo $[BITRATE*2]) --vbv-bufsize $(echo $BITRATE)\
  -o /tmp/video.mp4 /tmp/video.y4m
[ -e /tmp/video.y4m ] && rm /tmp/video.y4m

[ -e /tmp/audio.wav ] || time sox -S --temp /tmp /tmp/audio-raw.wav -c 2 
/tmp/audio.wav gain -n -3 gain -h dither -s
[ -e /tmp/audio-raw.wav ] && rm -f /tmp/audio-raw.wav

[ -e /tmp/audio.wav ] && time faac -b 96 -o /tmp/audio.aac /tmp/audio.wav
rm -f /tmp/audio.wav

[ -e /tmp/video.mp4 ] && MP4Box -new film.mp4 -isma -nodrop -add 
/tmp/video.mp4 -add /tmp/audio.aac

[ -e /tmp/audio.aac ] && rm -f /tmp/audio.aac
rm -f /tmp/video.mp4



PS: I have TMPFS at "/tmp" so it read/save files in memory (faster)
