Hi all, in my media streaming application I need to synchronize the stream output to a PTP GM. To do so, I have used ptp4l + phc2sys and then read CLOCK_REALTIME or CLOCK_TAI. This works well, but my problem is that the GM *might* be at randomized time and date, which is bad for the system time keeping.
I thought about using the PHC directly, but as I understand the time retrieval is contraint by bus speed and jitter, which is bad for low latency media streaming synchronization. Using phc2sys mitigates these constraints through algorithms I cannot even begin to understand and the clock retrieval from CLOCK_REALTIME is incredibly fast. So my question would be: Is there a way to use the synchronization algorithms of phc2sys for a "virtual" clock either in shared memory through a daemon process (maybe even phc2sys itself) or inside my application. So I can have fast, stable read outs of the PTP clock, while keeping the system clock PTP independent?
