Equivalent to the --lp option for SvtAv1EncApp, and is the only way
to control how much cpu power svt-av1 uses for now
Not using thread_count as it would be preferable to reserve that until
svt-av1 properly implements a threads option
Then what does it actually do? The description below about the number of
logical threads to run sounds pretty much exactly like what the threads option
does.
0 == getconf _NPROCESSORS_ONLN
