Hi, Lynne
I hear your concern about the decoder performance.
I believe that the way we would like to modify the decoder should not
affect its performance, since
AV_FRAME_QUANTIZATION_PARAMS will be disabled by default; the extraction is
done optionally with a flag.
I would be glad to verify that by running tests and measuring performance
with and without my changes.
If you have in mind any tests I should run, please let me know.

FFmpeg already has a lot of analyzing tools, I disagree that this change
does not belong to ffmpeg.
