@item reset
|

Set number of frame after which stats are going to be recalculated.

Set the number of frames over which cumulative stats are calculated before
|

being reset
|

Default is disabled.

@item measure_perchannel
|

Select the entries which need to be measured per channel. The metadata keys can

Select the parameters which are measured per channel. The metadata keys can

be used as flags, default is @option{all} which measures everything.

Select the parameters which are measured overall. The metadata keys can
