최근에 새로 구매한 아이팟 터치용으로 동영상을 인코딩하려 하는데.....
Fodora core 12 에서 FFMpeg 아래와 같은 옵션으로 돌릴려고 하니...

ffmpeg -i "INPUT.avi" -acodec libfaac -ab 128k -s 480x320 -vcodec mpeg4 -b 0.5M -flags +aic+cbp+mv0+mv4 -trellis 1 -mbd 2 -cmp 2 -subcmp 2 -g 250 -maxrate 0.8M -bufsize 2M -metadata "title=제목" -f ipod "OUTPUT.mp4"
 
뭐 대략 faac 오류...
알고 봤더니 아래와 같이 faac 옵션이 빠져있었다.
(사연은 non-free가 되었다는....)
