One approach that I’ve used with good success here is
to run
the decoded PCM through a FIFO buffer between the SRC and the
play-out stages and then use the size of that FIFO (which will
change dynamically in response to things like network congestion)
to feed a PLL that drives the converter ratio for the SRC stage.
Which is what zita-ajbridge and njbridge do in software.
The difference is that since data enters and leaves the
fifo in blocks of samples and not as a constant rate stream
it's a bit more involved to obtain the (average) FIFO size.

A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
