Set the timebase to use for the output frames timestamps.
It is mainly useful for testing timebase configuration.
It accepts in input an arithmetic expression representing a rational.
The expression can contain the constants "AVTB" (the
-default timebase), and "intb" (the input timebase).

The default value for the input is "intb".
