I am using it for android phone:

#!/bin/bash

'/ID_VIDEO_FPS/ {print $2}')
if [ "$FPS" = "23.976" ]; then FPS="24000/1001"; fi
AACQUANT="90"
X264CRF="16"

AUDIOFIFO="/tmp/fifo-audio.wav"
AUDIOTMP="/tmp/tmp-audio.wav"
AUDIOWAV="/tmp/audio.wav"
AUDIOAAC="/tmp/audio.aac"
AUDIORATE="-1"
FILEOUT="$(echo "$FILE" |awk -F"." '{gsub("."$NF,"");print
$0"-[android].mp4"}')"
ENDPOS="-1"
