this log is printed in apply_correction_if_needed_rtcp. it is because the new ntp does not meet requirement after calculating. could you share the whole media pipeline? ntp calclulation of nvstreamux is opensource after DS6.2. please download the latter versions by referring to this link.
How does CameraServerUnit and MainServerUnit affect the ntp？NTP correction is based on incoming NTP values. please fix the issue of the abnormal ntp first.
