I got the reported issue.
One bit that fixed a race condition was missing from the patch. I pushed
to ppa:nteodosio/wirepipe and tried in 24.04 but it doesn't seem enough
to fix the problem. My error message is different though ("could not
play camera stream") and stderr says

<---
mpv av://v4l2:/dev/video0 has of course no problem playing back from
either camera.
