Sziasztok,
Sok guglizás után sikerült összekalapálnom egy bash scriptet, amivel mar 4CPU-van tudom konvertalni a .mkv-t .avi-ba. Ha valakinek van öttlete, hogy lehetne jobbá tenni a scriptet, akkor irjatok és beépítem. Hozzá kell tegyem, nagyon nem értek a bash script-hez, ezt is legalabb 3 órán keresztűl szültem.
#!/bin/bash
clear
NAME=`echo $1 | sed 's/\.[^.]*$//'`
D1=`mkvinfo $1 | grep Duration: | cut -d" " -f4 | cut -d. -f1`
QL=$((D1/4))
declare -a pids
function encode_part {
num=$1
ss=$(((num-1)*QL))
echo "encoding $num will start at $ss"
rm -fr $num
mkdir $num
cd $num
mencoder -o $NAME.avi -alang hun -msglevel all=-1 -endpos $QL -ss $ss -oac copy -ovc xvid -xvidencopts bitrate=9500:vhq=4:pass=2:max_key_interval=200 ../$NAME.mkv & pid=$!
cd ../
pids[$num]=$pid
echo "encoding started with pid $pid"
}
echo "Filename: $NAME"
echo "Duration: $D1 seconds"
echo "Quarter length $QL seconds"
for i in `seq 1 4`;
do
encode_part $i
done
echo "wait until all process ends"
wait ${pids[1]}
wait ${pids[2]}
wait ${pids[3]}
wait ${pids[4]}
mencoder -forceidx -oac copy -ovc copy -o $NAME.avi 1/$NAME.avi 2/$NAME.avi 3/$NAME.avi 4/$NAME.avi
rm -fr 1
rm -fr 2
rm -fr 3
rm -fr 4
exit
Az elkészült avi file (csak videó és magyar hang) álltalában kissebb mint az mkv (ami persze függ az eredeti videó bitrate-től) és gond nélkül lejátszható PS3-on. Én MediaTomb-ot használok upnp szerverként. Minőségromlást nem tapasztaltam, igaz a plazmám csak kb 720p-t tud. Az összes CPU 100%-on pörög és tényleg negyed annyi idő kell az újrakódoláshoz.
Itt a kimenete egy rövid mkv konvertálásnak:
