Good question. “Repackaging” may be the wrong word, but BI must do something to take an RTSP stream and turn it into a file on a disk. There is no transcoding occurring with BI’s “direct-to-disc” feature, because the reason for that feature is to reduce CPU utilization, and Task Manager on the BI computer shows that it’s very, very low. But BI must at last write some sort of file name, file header, EOF marker, etc., right?
I tried ffprobe with the streams directly from these same 3 camera that produced the clips posted previously, and they all show no errors:
