The issue here was that our RTSP *server* implementation (code) depends on the presentation times for outgoing frames (transmitted by the server) being aligned with the server's ‘wall clock’ time (in order for the server’s outgoing RTCP “Sender Reports” to be correct). Therefore, when our ‘server’ is actually a proxy server (which takes its input from some other, ‘back-end’ server, not necessarily implemented by us), we can’t just use the presentation times that came from the ‘back-end’ server ‘as is’. Instead, we need to adjust them so that they’re aligned with the proxy server’s ‘wall clock’ time. That’s what “PresentationTimeSessionNormalizer” (and “PresentationTimeSubsessionNormalizer”) does.
