@ -1749,12 +1749,6 @@ The default is -1.1. One possible usecase is to avoid framedrops in case
of noisy timestamps or to increase frame drop precision in case of exact
timestamps.
@item -adrift_threshold @var{time}
Set the minimum difference between timestamps and audio data (in seconds) to trigger
adding/dropping samples to make it match the timestamps. This option effectively is
a threshold to select between hard (add/drop) and soft (squeeze/stretch) compensation.
@code{-async} must be set to a positive value.
@item -apad @var{parameters} (@emph{output,per-stream})
Pad the output audio stream(s). This is the same as applying @code{-af apad}.
Argument is a string of filter parameters composed the same as with the @code{apad} filter.
