splitmuxsink can only break files at a keyframe boundary, and will
always try and keep files shorter than the maximum. To make sure that
things can break at exactly 1 second intervals, you need keyframes at
those positions. If your GStreamer install is recent enough, you can use
the send-keyframe-requests=true property on splitmuxsink to send encoder
requests to create keyframes at the right position, otherwise, tune your
key-int-max and input framerate to generate keyframes at 1 second intervals.

Regards,

Jan.
