v27 v28 15 15 [[Image(out.jpg)]] 16 16 17 This example will produce one image frame (out1.jpg) at the twenty-third minute from the beginning of the movie. The input will be parsed '''using keyframes''', which is '''very fast'''. As of FFmpeg 2.1, when transcoding with `ffmpeg` (i.e. not just[https://ffmpeg.org/ffmpeg.html#Stream-copy stream copying]), `-ss` is now also "frame-accurate" even when used as an input option. Previous behavior (seeking only to the nearest preceding keyframe, even if not precisely accurate) can be restored with the `-noaccurate_seek` option.17 This example will produce one image frame (out1.jpg) at the twenty-third minute from the beginning of the movie.
