You do not seem to notice that you make the same mistake,
using emotionally charged expressions.

You are insulting the people who use older hardware, which is
_not_necessarily_ "trash" and who do this for their reasons - good or
bad is not in the realm of one's competence unless one is involved in
the actual case.

You the developers know everything between CPU, memory and I/O. The user

I did my best to contribute some small bits of code and of understanding.

To conclude, I would like to friendly suggest to every bright
programmer on this list (sincerely highly respecting your skills),
try to notice when you tread outside your competence area.

Good luck to the ffmpeg project, my humble effort here is over.
