Sets/gets the current audio mixer for non-encoded outputs. For
multi-track outputs, this would be the equivalent of setting the mask
only for the specified mixer index.

.. function:: void obs_output_set_mixers(obs_output_t *output, size_t mixers)
size_t obs_output_get_mixers(const obs_output_t *output)
Sets/gets the current audio mixers (via mask) for non-encoded
multi-track outputs. If used with single-track outputs, the
single-track output will use either the first set mixer track in the
bitmask, or the first track if none is set in the bitmask.
