Hello
I tried the following command to split an MP4 video exactly, which means re-encoding the video stream, while keeping the audio as-is since it was good enough:
Even though I used the "-shortest" option, ffmpeg keeps going past the length of the video (which is about 15mn, and I stopped ffmpeg at around 23mn).
Does someone why, and if there's a way to avoid needlessly re-encoding the audio stream as well?
Thank you.

Edit : I tried the "-to" option introduced in 2013, to no avail:
