Looks like something inconsistent possibly in the logs, config,
MotionPlus and camera.? The config posted seems to request that the
image be scaled down to 800x600
*?The full URL of the network camera stream.**
**netcam_url rtsp://xxxx:[email protected]:554/12**

The 2560x1920 dimensions are for the high-res stream. I commented them
out when I switched to the low-res stream so I could remember the values
when I figure out where they should go. The 800x600 resolution is the
actual dimensions of the low-res stream coming from the camera.? Could
MotionPlus possibly be still using the commented ones?? I would think
that, even if that were the case, the later values would take
precedence.? I can try removing them altogether.
