Hi list!
I'm having this weird issue when using motion, that when motion is detected, it
garbles the image [1][2] along the change (i.e.: motion). Also sometimes half
or most of the screen is just missing.
This is a Besder net camera, using RTSP UDP streaming. I've tried to fiddle
with a couple of options regarding motion detection but to be honest I don't
quite understand them (other than figuring out the threshold), so eventually I
just left everything at the default setting.
I've also tried to change the resolution (in motion(1) config) to a lower one
(from 1080p to 720p, and even halving it to 540p), tried to lower the built-in
movie quality setting, tried to use passthrough and tried to use the extpipe
option to define my ffmpeg command line, but sadly the issue persists anyway. I
even turned off movie recording at one point and just tried to save pictures,
but every so often this happened on the pictures as well.
Also I'm usually getting these errors every now and then:

What I can tell otherwise, is that when recording from the same camera with
ffmpeg(1) and encoding it with libx264 or even using -codec:v copy, there's
nothing wrong with the picture. What I actually do currently is just running
ffmpeg and slicing up the video files every 3 minutes or so:
$ ffmpeg -hide_banner -loglevel warning -y -threads 0 -an -f rtsp -i
rtsp://kamera-eloszoba/onvif1 -codec:v copy -reset_timestamps 1 -f segment
-segment_time 00:03:00 -strftime 1
/mnt/storage/motion/Eloszoba-BESDER_6024PB_JW201-%Y%m%d@%H%M%S.mkv
This produces good movie files, and not a trace of the quirky artefacts that
are on the sample videos and image files I'm attaching. Also, when the picture
is still on the video recorded by motion(1), there seems to be no problem and
it seems the issue shows up with motion -- no pun intended :)
Any insight would be greatly appreciated!
