[MEncoder-users] trouble creating a mp4 file

[Alex Samad]

Hi

I am trying to encode some mpeg src files (from a panasonic video camera)

this is the jist of the script

INFILE="$1"
OUTFILE="${INFILE/.mpg/}.mp4"

# Passlog
	PASSLOG="$WRKDIR/divx2pass.log"

	# Higher - 1500
	# High - 1400 2cd
	# Normal ? - 700  1cd
	BITRATE=${BITRATE:-1000}


	ENC1="x264 -x264encopts 
subq=4:bframes=4:b_pyramid:weight_b:pass=1:psnr:bitrate=$BITRATE:turbo=1"
	ENC2="x264 -x264encopts 
subq=5:partitions=4x4:8x8dct:frameref=3:me=hex:bframes=4:b_pyramid:pass=2:psnr:bitrate=$BITRATE"

	AENC="-af volnorm=1"

	FILTER1="-vf crop=704:464:6:58"
	FILTER1=""
	FILTER2="-vf spp,hqdn3d=2:1:2,crop=704:464:6:58"
	FILTER2="-vf spp,hqdn3d=2:1:2"

	# Audio
	AUDIO="-oac faac -faacopts object=1:tns:quality=300:mpeg=2"

	LAMEOPTS="preset=standard"
	#LAMEOPTS="br=96:cbr:vol=6"
	AUDIOOPT="-lameopts "$LAMEOPTS""
	#AUDIO="-oac mp3lame $AUDIOOPT"

	# Apect ratio input !?
	ASPECT="-aspect 16:9"

	# Additional stuff
	ADDOPT="-frames 300"
	ADDOPT=


	nice mencoder -quiet \
			$ASPECT \
			-alang en\
			$FILTER1 \
			-ovc $ENC1 \
			-oac copy \
			-passlogfile "$PASSLOG" \
			-o /dev/null \
			"$INFILE" $ADDOPT

	nice mencoder -quiet \
			$ASPECT \
			-alang en\
			$FILTER2 \
			$AENC \
			-ovc $ENC2 \
			-passlogfile "$PASSLOG" \
			$AUDIO \
			-o "$OUTFILE" \                                                                                             
"$INFILE" $ADDOPT

when I run this again one of the files, I get this with identify
Playing MOV001.mp4.

ID_DEMUXER=avi worries me ?

Also I can't hear any audio when played on a windows box, with media player or 
vlc - I have the ffdshow codecs install

I remember reading (here I think) that aac + H264 in avi can have problems in 
audio such that only mplayer can play it.  And mplayer plays the output okay.

I can work around by using mp3, but I thought I would ask the list first 

I will see if I can find a newer version of mencoder as well

Thanks 

Alex
