ffmpeg ts2mp4 コマンドメモ cpu爆音を奏でる

compless()
{
if [ ! -f "${1%.m2ts}.mp4" ] ; then
echo "$1" "${1%.m2ts}.mp4" `pwd`
nohup nice -n 19 ffmpeg -y -i "$1" -threads 0 \
-deinterlace -f mp4 -vcodec libx264 -vpre hq-ts-v2 -level 40 -refs 3 -bf 3 \
 -r 30000/1001 -aspect 16:9 -s 1920x1080 -bufsize 80000k -b 4000000 -maxrate 8000000 \
   -strict -2 -acodec aac -ac 2 -ar 48000 -ab 128k \
  "${1%.m2ts}.mp4" &
fi
}

bashでよろ
