[MPlayer-users] Fwd: Trying to split avi file using mencoder

[wim delvaux]

Hi all,

Look at this little shell script :

if [ "$1" == "" ]
then
  echo "usage $0 filename"
  exit 2
fi

# calc half
FS=`ls -s --block-size=1 "$1"`

BS=${FS% *}
let BS=BS/2

Ext="${1##*.}"
BN="${1%.*}"

# avisplit -i "$1" -o "$BN" -s ${FS%.*}
# set to proper encoding
mencoder -ffourcc XVID -ovc copy -oac lavc -lavcopts
acodec=ac3:abitrate=224 -endpos ${BS}b "$1" -o "${BN}-1.${Ext}"
mencoder -ffourcc XVID -ovc copy -oac lavc -lavcopts
acodec=ac3:abitrate=224 -sb ${BS} "$1" -o "${BN}-2.${Ext}"


The first mencoder works just fine.

The second one produces following error which I do not understand
