This filter needs to be marked as having only one input by default, with
AVFILTER_FLAG_DYNAMIC_INPUTS allowing the extra input to be added at
init() time.

This is similar to h264, but here we use manual_avg instead of vaaddu
because rv40's OP differs from h264. If we use vaaddu,
rv40 would need to repeatedly switch between vxrm=0 and vxrm=2,
and switching vxrm is very slow.

As we do not need to widen accumulators to 64 bits, we effectively get
double capacity for unrolling compared to the integer function. This
explains the slightly better performance gains.
ac3_sum_square_bufferfly_float_c: 65.2

This is automatically enabled if the width/height expressions reference
any ref_* variable. This will ultimately serve as a more principled
replacement for the fundamentally broken scale2ref.

flag is set.

Before 0f8763fbea, av1_frame_ref()
and update_reference_list() could fail and therefore needed to
be checked, which incidentally set ret. This is no longer happening,
leading to a potential use of an uninitialized value which is
also the subject of Coverity ticket #1596605.
Fix this by always setting ret before goto end; do not return
some random ancient value.

This version is seven years old, and present in Debian oldoldstable,
Ubuntu 20.04 and Leap 15.0.
Allows cleaning up the file substantially. In particular, this is
motivated by the desire to stop relying on init_static_data.
Some versions of xargs don't run any commands if no input is given,
others do run it at least once, causing errors.
Pass -r to xargs to avoid that behaviour and never run empty commands.

Currently it always copies the metadata fields from the last input when
there are multiple inputs for the filter. For example, the metadata
fields from input1 are copied to the output for overlay_qsv filter,
however for regular overlay filters, the metadata fields from input0 are
copied to the output. With this fix, we may copy the metadata fields
from input0 to the ouput as well.
