You should probably ask the provider of the stream 
analyzer for more information.
What stream analyzer is it?

Can you reproduce the issue with testsrc input?

This does not work.
(Only one "-vf" per output file is supported)

If you use a filter chain, do not use -s, 
while it works, it is to some degree 
undefined behaviour. Use the scale filter 
instead.

I would suggest you try to reproduce with less 
options, then you could try (much!) older 
versions of FFmpeg (they will not support 
testsrc, you will have to produce a rawvideo 
input first) to find out if this is a 
regression.

These options have no effect, I suggest you 
remove them.

This adds a (very) low quality aac encoder, 
please remove it.

> --enable-hardcoded-tables

Just being curious: Why?
