> We've shown that many measurements of latency [...] ignore the full capture and playback pipeline

In the repo linked in OP is a screenshot showing a wall clock next to its playback on the streaming site -- that's end-to-end to me. So how is this relevant?

Because latency is a distribution and these photos are often selected at the best-case P0 end of all the encode/decode processes whereas actually what matters is the worst case P99.

A proper implementation will make sure the worst-case latency is accounted for and not cherry-pick the best case.
