Hi Devin,
I saw your patch but noticed it was still not merged. Since it’s more comprehensive, I’m all for merging your patch instead of mine if it’s not too stale.

Best,
Pierre

For what it's worth, I submitted a similar patch series a couple of
years ago, which also accommodates modifying the pts_adjust field
(which is mandatory if the output stream's clocks are rebased).
