5 years ago Error in iframe list occur when it loses sync with the stream of data from the camera. It will normally recover after a burst of these. I am not sure what can trigger them (maybe cpu gets diverted onto other stuff for a short while) but they should be pretty rare.
DEBUG 3 occurs when it is lining up the buffer. You get one of these when the buffer is being used and the settings are changed or when a capture completes. They are quite normal.
Pi-DD
I was looking at the logs because motion capture had not happened when I would have expected some. (This is running on a remote device 90km away, how I deduce some captures have been missed does not matter!)
I found that DEBUG 3 appears in the logs, usually after reference to the motion mask file.
example....(this follows re-start after update to 6.4.36)
