You can issue a seek event with a 'rate' of other than 1.0, e.g. 0.5
for half-speed, or 4.0 for quadruple speed.
Negative rates are also permissible (for backwards playback), but are
not implemented for all formats, so don't work very reliably unless
you have a tightly constrained set of input formats.
