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

Hi Roger/All who are following this!


Just to keep up-to-date: At about 4 o’clock (1600) yesterday afternoon I 
reset my Pi4’s gpu_mem from 512MB to 256 MB. Seems counter-intuitive to 
decrease the graphic memory for video problems but maybe I was starving 
the CPU. Anyway, at the time of the update Camera1’s video feed (to the 
monitor) had been frozen for a couple of hours. Camera2’s video feed was 
chugging along happily. Both cameras were sending motion-triggered 
recordings to the NSA.


Did a reboot to update the memory configuration. Since then things seem 
to be working as they should – have had previous fixes works for a while 
so not celebrating yet. Both cameras seem to be holding at 5 fps, though 
have seen a one to two second video freeze; might try cutting gpu_mem a 
little more. (The gpu_mem in the Pi4 works differently from earlier 
versions; if somebody reading this is using a Pi3 might make things worse.)



I semi-figured out logging to it’s own file: in motion.conf I have 
*log_file /mnt/NSA320/Unit_1/%m-%d/motion.log* ==> to the server in the 
basement, Unit #1’s partition (clever name, huh?!). The what I wanted it 
to do was to a daily file, hence the month and date variables but 
they’re not working; work elsewhere. Figuring the log_file field doesn’t 
input variable but rather a literal. Works in movie_filename, which is a 
‘type: string’ as is log_file, per 
https://motion-project.github.io/motion_config.html . OTOH might not be 
necessary to have separate/daily logs: relatively short. I had looked at 
syslog which was constantly updating and HUGE.


Suggestions? It also looks like motion.log with the default level of 6 
only logs at boot start, though I haven’t done a motion restart.


..I just took a closer look at motion.log: it /is/ updating! The file 
was created yesterday and here the ‘Modified’ column is showing 
‘yesterday’ as opposed to the time of the last entry a few minutes ago. 
Just assumed (yeah: I know!) when I saw ‘yesterday’ it hadn’t been altered.
