推荐答案

使用 -ss 和 -t 选项:

ffmpeg -i input -t 00:15:00 -codec copy output
ffmpeg -ss 00:15:00 -i input -codec copy output

从 FFmpeg文档:

   -ss position (input/output)
       When used as an input option (before "-i"), seeks in this input
       file to position. Note the in most formats it is not possible to
       seek exactly, so ffmpeg will seek to the closest seek point before
       position.  When transcoding and -accurate_seek is enabled (the
       default), this extra segment between the seek point and position
       will be decoded and discarded. When doing stream copy or when
       -noaccurate_seek is used, it will be preserved.

       When used as an output option (before an output filename), decodes
       but discards input until the timestamps reach position.

       position may be either in seconds or in "hh:mm:ss[.xxx]" form.

   -t duration (output)
       Stop writing the output after its duration reaches duration.
       duration may be a number in seconds, or in "hh:mm:ss[.xxx]" form.

       -to and -t are mutually exclusive and -t has priority.

该示例使用-编解码器复制来使用流复制模式，而不是重新编码.

The example uses -codec copy to use stream copy mode instead of re-encoding.
