[Motion-user] Psychedelic Pictures

[David P. <da...@de...>]

I have a strange issue with Motion using RTSP cameras.  I have Motion 
version 4.1.1+git20181002-062a328 running on a Raspberry Pi controlling 
3 MJPEG cameras and 2 RTSP cameras.  They all work fine at night with 
the IR lights and all, but when the sun comes up, one RTSP camera (and 
to a lesser extent, the other RTSP camera) will, over an hour or so, 
slowly start changing colors until it looks like a black-light poster 
from the 70's.  Here is an example (hopefully, if images are allowed on 
this mailing list).

This is what it should look like:

This is what it should look like


This is the view after an hour:

That's messed up!

If I restart that camera (Action->Restart), it immediately clears up but 
starts to degrade again after a few minutes.  The other RTSP camera does 
the same thing, but to a lesser extent. None of the MJPEG cameras has 
ever behaved thusly.

The motion log shows a couple of these per hour of operation for this 
camera:

/[12:nc12:shed] [ERR] [NET] [May 10 15:24:07] 
netcam_rtsp_handler_reconnect: Normal resolution: Reconnecting with 
camera..../

I thought I might have just bought a couple of crappy cameras, but even 
when the picture is messed up I can stream it with FFPLAY and it looks 
fine there.

I'm not even sure where to begin trying to fix this. I've checked the 
resolution setting and it is correct.  Has anyone else seen this behavior?
