ffmpegで動画から静止画を抜き出す

More than 5 years have passed since last update.

1)動画を再生して抜き出す始点と終点の時間を確認.

2)ffmpeg で静止画に抜き出し

$ ffmpeg -i 元動画.avi -ss 144 -t 148 -r 24 -f image2 %06d.jpg

-i 元動画.avi : 元動画
-ss 144 : 抜き出し始点(秒)
-t 148 : 抜き出し終点(秒)
-r 24 : 1秒あたり何枚抜き出すか
-f image2 %06d.jpg : jpeg で[000001.jpg]から連番で書き出し

以前とオプションが変わっているようなのでメモ

ffmpeg version 0.7.3-4:0.7.3-0ubuntu0.11.10.1, Copyright (c) 2000-2011 the Libav developers
