ffmpeg 인덱스 재생성

• for single play (no fix): mplayer -idx myvideo.avi
• fix it: mencoder -oac copy -ovc copy infile.avi -o outfile.avi
• in case of serious damage use ffmpeg which is more fault tolerant: ffmpeg -i infile.avi -acodec copy -vcodec copy -o outfile.avi
• save index: mplayer -idx myvideo.avi -saveidx myvideo.idx
• use saved index: mplayer myvideo.avi -loadidx myvideo.idx
