[Libav-user] Best way to create a fractional ms timer?

I believe you are wrong: you mix timer precision and time slice.

On a NOHZ Linux x86_64 kernel and an idle system, the precision of nanosleep
seems to be 100 µs, but if your system is busy, the process will be
preempted for a full time slice, and that is much larger, above 500 µs.
