Re: [Motion-user] Gray glitching but only one of of two identical cameras

Hi Mark!


Update – probably bad form not to wait for a reply so I apologize for 
that but followed through on some of my considerations from the earlier 
post.


Verified I had been using two different versions of Motion; listed on 
the IP_addr:8080 webpage – of course I look at the individual cameras 
pages where I get full screen and so don’t see.Eventually found /motion 
-h/ displays the version also. So, the RPi with the two glitching 
cameras I’ve been playing with is version 4.1.1 and a different RPi with 
one camera and AFAIK never glitches is version 4.3.2. Is this the “It’s 
this!” we’ve been looking for??!!


<modify-test-correct typo-retest> Nope, not the cure. I don’t think even 
made any difference. Good news is at least I’m using the current version 
of Motion now.


I’m starting to think the problem is with the cameras. Right now not 
sure how to test in a live scenario – getting to the window where the 
current cameras are isn’t all that easy. It seems the glitching problem 
is worse with a bright day, though also occurs when overcast, just to a 
lesser degree Might be able to rig a test out a different window but 
requires two, maybe three USB extensions (that could give a garbage 
signal!)…. Powered hub partway?…. (I’m sort of typing to myself to get 
ideas.)


I tried to do a bit of investigation with the vendor:model number from 
lsusb:

    32e4:9422 Both cameras of the RPi with the glitching.
    SV-USBFHD06H-BL36 (SVPRO Brand), which appears to be the same as the
    ELP ELP-USBFHD06H-BL36.


    32e4:9320 ELP-USB130W01MT-BL21 – camera has no glitching; this RPi
    had the newer Motion version and so I cloned from this unit to the
    one that glitches.


I couldn’t find these codes when I went to https://usb-ids.gowdy.us 
<https://usb-ids.gowdy.us/> and that’s the only site I know of.


OK, ‘nuff for now.
