Hi Harlan,
I hear the hope in your voice. Sorry no, it has no effect on my issue.
top cpu% is also same as before.
To my understanding of the 50-60 hz setting, it will prevent the shutter
speed from aligning with that corresponding value.
But! I have experienced the drift you mentioned, last year, with low
quality 640x480 streams. My solution at the time was to increase my
playback speed above 1.00% to 1.02 in mpv.
That usually kept it live. Then months later, last November, I figured
out the issue was the clock on my desktop motherboard, it started
drifting a lot. Values like 14 seconds per hour, and ntp was no longer
fixing it for me. I proved this by writing a program that read the
time(), waited 1.0 sec, loop, if time2-time1 not equal 1 then increment
a counter.
I replaced the motherboard with the same model, KBN-I5200. Bingo,
problem solved.
If you run linux I can share that perl script.
Since there were so many others with puzzling streams drifting, I'll
post to the group.
