    avfilter: Deduplicate default audio inputs/outputs · 50ea7389
    Andreas Rheinhardt authored
    Lots of audio filters use very simple inputs or outputs:
    An array with a single AVFilterPad whose name is "default"
    and whose type is AVMEDIA_TYPE_AUDIO; everything else is unset.
    
    Given that we never use pointer equality for inputs or outputs*,
    we can simply use a single AVFilterPad instead of dozens; this
    even saves .data.rel.ro (4784B here) as well as relocations.
    
    *: In fact, several filters (like the filters in af_biquads.c)
    already use the same inputs; furthermore, ff_filter_alloc()
    duplicates the input and output pads so that we do not even
    work with the pads directly.
