The above missing "format=" is the problem, it appears
pjmedia_vid_dev_get_info(prm->vidparam.cap_id, &di);
few lines above returns '0' in di.fmt_cnt, for whatever reason.
Simply replacing the assert with
vparam.fmt.id = 0x59565955; /* UYVY */
only to prove that now the quicktime camera video transmission works as
well...
(Not investigating any further for now.)
