The default value is 10 seconds.
@item -dts_delta_threshold
Timestamp discontinuity delta threshold.
@item -dts_error_threshold @var{seconds}
Timestamp error delta threshold. This threshold use to discard crazy/damaged
timestamps and the default is 30 hours which is arbitrarily picked and quite
conservative.
@item -dts_delta_threshold @var{threshold}
Timestamp discontinuity delta threshold, expressed as a decimal number
of seconds.
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.
The default value is 10.
@item -dts_error_threshold @var{threshold}
Timestamp error delta threshold, expressed as a decimal number of
seconds.
The timestamp correction enabled by this option is only applied to
input formats not accepting timestamp discontinuity (for which the
@code{AV_FMT_DISCONT} flag is not enabled).
If a timestamp discontinuity is detected whose absolute value is
greater than @var{threshold}, ffmpeg will drop the PTS/DTS timestamp
value.
The default value is @code{3600*30} (30 hours), which is arbitrarily
picked and quite conservative.
@item -muxdelay @var{seconds} (@emph{output})
Set the maximum demux-decode delay.
