+The timestamp discontinuity correction enabled by this option is only
+applied to input formats accepting timestamp discontinuity (for which
+the @code{AV_FMT_DISCONT} flag is enabled), e.g. MPEG-TS and HLS, and
+is automatically disabled when employing the @code{-copy_ts} option
+(unless wrapping is detected).
+
+If a timestamp discontinuity is detected whose absolute value is
+greater than @var{threshold}, ffmpeg will remove the discontinuity by
+decreasing/increasing the current DTS and PTS by the corresponding
+delta value.
