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.
