I have an issue with one particular monitor feed giving warnings. I'm not exactly sure how to rectify the situation. I am getting errors that say:

Code: Select all

It is ONLY with this particular monitor. I thought it had something to do with the buffers, so I've experimented and changed many values, but nothing seems to fix the issue. I don't need my log to be perfect, but I want to work out as many kinks as possible.

So... if you have pre_event_coutn set to 5 (the default):

When we start up and let's say right off the bat at image 4 we get a motion event, or maybe we are recording full time. We alert, we go into the packetqueue and we try to rewind 5 packets. But we have only received 4.. so then we hit the end and we log that message.

In 1.37 ( and I am looking at merging it for 1.36.35) we do not even begin motion detection or recording until we know the keyframe interval and have at least 5 packets decoded, as opposed to just received.

So you won't see that message in 1.37.. and hopefully not in 1.36.35.
