I’ve played this file in my debug environment and have not seem a dropped frame either with omxplayer or mmmal.
It’s possible there are differences between the Jarvis and Krypton code, but switching branches takes a while to rebuild so I can’t do that now.
I would be interested if that file plays okay locally - can you copy it to sdcard or a usb stick?
I’d also be interested if you can test it with a Krypton build, in case the issue has been fixed.
BTW, what did you spot in the log? I didn’t see anything wrong.
