[FFmpeg-user] Video in video not from start

[Cecil Westerhof]

I want to play a video in a video from a certain point. I understood I
could do something like:
    ffmpeg              \
      -i input1.mp4     \
      -i input2.mp4     \
      -filter_complex "
        [0:v][1:v] overlay=25:25:
        enable='between(t,8,20)'
      "                 \
      -pix_fmt yuv420p  \
      -c:a copy         \
      output.mp4

But this starts input2.mp4 from the start of input2.mp4 on the 8
second, for twelve seconds.
Is it possible to let input2.mp4 not start from second 0, but from
second 17?
