upstream_newsegment isn't really clear on what it means, it is set to TRUE when the upstream element sends a segment in TIME format, so rename it to be more clear about it. It is important to know this because it means that upstream has a notion of time and qtdemux is likely being driven by an upstream element that is reading from a higher level abstraction than a file, such as a DASH, MSS or DLNA element.
