I know nothing about the optimal resampling and FLAC encoding options.
You don't say what you are trying to achieve.
That said, this I can comment:

- You cannot specify multiple filters with "-vf" or "-filter:v". You
need to read about how to chain filters.
- The syntax for handing options to your filters is incorrect. It is
not
"filter=opt1=val1=opt1=val2=..."
but rather
"filter=opt1=val1:opt2=val2:opt3=val2:..."
- The whitespace in your (first) filter chain (", dynaudionorm") needs
to be protected from the shell.
- "shibata" is not a filter. It is an argument to the resampler's
"-dither_method" option.
