This is wrong function to check for input parameters.
Function is not needed because query_formats() already
sets supported sample rates.

outpicref is not always in synch with showwaves->outpicref, which is
changed as a side effect of the call to functions.

Correct the time interval between logged data rows to the expected
value of 100 milliseconds by naming a new loop counter variable
to be distinct from loop counters for inner loops that
inadvertently change the outer loop operation.

This suggested patch is 1 of 3 for Ticket #2144 "libavfilter ebur128
loudness inaccuracy, irregular time interval, LFE interference".
This suggested patch supersedes the contribution of January 15, 2013
in the thread “[PATCH] lavfi: EBU R.128 irreg time, ch weights, skip
LFE” which combined multiple fixes in one patch.

If nb_samples divide sample_rate and if nb_samples allow it, aevalsrc
should generate the exact amount of samples according to duration.

Example:
aevalsrc=0::n=480:s=48000:d=5.21 should generate 250080 samples.

EAGAIN is used internally in the code; it currently does not make
sense as a return code from the next filter.

This makes the code faster.

This was supposed to be removed in 565e4993, but it was delayed due to
the port of the remaining filters. These buffer ref pointers are not
used anymore, thus dropped.

This might fix fate failures.

Also rename the "enable_auto" field to "deint", to match the name of the
option.

This is better than repeatedly failing during the filtering stage.

"que" sounds like a slang word to me. This commit renames a few

It is the same as avfilter_get_audio_buffer_ref_from_arrays
except it has a "channels" and the channel layout can be 0.

%f denotes a double argument and 'l' does nothing in this case
according to the C spec.
