Pi 4 with 1.32.2 - only 1 camera works

Post by fatboy » Sat Nov 02, 2019 3:55 pm

I have zoneminder 1.32.2 running as a Xen VM Buster. 6 Zero W's (mix of stretch and buster raspbian) running rtsp via github.com/mpromonet/v4l2rtspserver installed w/.deb, 1024@10fps. /dev/shm: 47% with 3 CPU's@3GHz and 4G RAM. Pretty much wonderful!!!

Have new pi4 w/4G ram, elcheapo KESU 250G USB3 hard drive from our buddy Bezos, as root partition, not overclocking yet (a bit cranky w/undervoltage even with pi power supply, seems to recover quick enough - did the I did the usb-storage.quirks=174c:55aa:u for occasional disk timeout, will leave it running at 2GHZ full time - see if this thing can hang) but am ready, thanks to yet another purchase from Jeff - aluminium pi case with dual fans.

I've reproduced my working install on the pi (it's hard wired, wireless doesn't work - to many dropped packets ;~(>

I add my 1st pi, works great. add the 2nd pi and works, but kills the 1st pi feed, added again this AM and 1st pi works, second doesn't - or vice-versa depending on "who knows" - whatever!

For grins I made a note in zmdc.pl:
per https://github.com/ZoneMinder/zoneminde ... 992a2998e1 - it is there by default on 1.32.2!
my $fd = 3; # leave stdin,stdout,stderr open. Closing them causes problems with libx264

Kinda thinking a hardware issue (bleeding edge pi).

Any thoughts/experience appreciated!

You moved from a Xen VM to an RPI, am I correct? That is moving from x86 to ARM. ARM can't keep up with the same number of cameras. You can probably get more than one though. Try lowering the FPS on the cameras, and see if you can get two running. You can also lower the Resolution. That is my first guess.

Nobody?

CPU's are about idling, 3G ram free, no swapping.

From sysadmin point, everything looks good.

I upgraded the usb3 7200 rpm WD, using the known to work adapter - StarTech SATA to USB Cable - USB 3.0 to 2.5” SATA III Hard Drive Adapter (USB3S2SAT3CB) , no usb timeouts, kern.log is clear as a bell.

Only thing I'm seeing is in the apache error.log:

Unable to connect to zmc process. Please ensure that it is running.: /usr/lib/zoneminder/cgi-bin/nph-zms, referer: http://x-pi4/zm/index.php?view=watch&mid=1

Which makes perfect sense if I'm trying to view a stream that isn't working.

Thoughts appreciated!

Working *great* now!

Increase GPU memory:

/boot/config.txt

gpu_mem=512
