[FFmpeg-devel] [PATCH 2/3] idet improvements: add reset_count feature

[Kevin Mitchell]

I made the decay multiplication fixed point. I moved all the fixed
point logic to macros which hopefully makes it easier to read.

I also removed the total_frames count since it is now likely to become
inconsistent with the actual classification totals anyway.

I've gone back to just outputting rounded integers to av_log so as not
to break scripts of people who are insane enough to try and parse it
(bash can't handle float).

I used your suggestion for formatting fixed point decimal values for
the metadata tags.
