My own set of commands is almost identical. I just used different layer numbers for each of them. I run 7 cams on a pi 2, however some of them are super small streams while at least one is 1280x720.

I'll try modifying the layer numbers, didn't think (or notice) that previously. I'm not all that certain about the command options with Omxplayer and should probably read up on the syntax.
7 on a RPi2? That's not bad, even with the variety of stream sizes. Worse case I can get another monitor and RPi to show more streams. Still much cheaper than a whole other desktop just to display security cameras.

OK finally got around to looking at this. Are you guys running this on the desktop Raspian OS on the pi or the streamlined CLI only OS?
I'm command line only version and can't get it to autostart the web service. Manual load is fine. Still have to configure the cameras.

Some autostart methods work specifically with the GUI and won't work with a CLI-only installation. Try adding the startup command to rc.local instead.

Ok i must be doing something wrong with my syntax:
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
sudo /home/pi/omxplayerauto/start.sh
# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
printf "My IP address is %s\n" "$_IP"
fi
exit 0

*7/24/19 update*
While the RPi works wonderfully with Omxplayer, I cannot get it to work on the second monitor. I tried every combination of --display n that I could think of without success. Normal desktop graphics work normally on the primary and secondary monitor. I also tried an x,y range outside of the primary monitor that would put it on the secondary monitor and that was unsuccessful also.
I'll keep tinkering with it next week but it's going on the shelf for now. The 'old' setup of 2x RPi3s work great!
*7/23/19 update*
PSA: The RPi4 works great with OmxPlayerAuto, just don't forget to set your memory split! The current version of Raspbian as of this post has a default of 64mb for the GPU. I'll post additional updates if anything useful comes up.
*Original Post*
PSA: I tested OmxPlayerAuto on a RPi4 and for some reason it won't play more than 4 streams at a time (in my 3x3 configuration). Not sure if it's because of the different GPU/software or what but wanted to share in case anyone has a similar issue. My old RPi3 boards still work OK with the same config.
I'm happy to provide log/debug output for anyone that is curious.

@Jmtyra Maybe your RPi4 doesn't have as much memory allocated to the video device? I really have no idea how OmxPlayer works internally; only that it accesses the pi's hardware video decoder. Enough people use pi for video walls that I'm sure if there is a widespread problem it will get figured out sooner or later.
*DING* *DING* *DING* We have a winner! @bp2008 That was exactly it, the setting was at the default 64mb. I should have checked that first!!! 
After changing that it worked flawlessly. I'll update the earlier thread for anyone else who might come across this or when they're considering a RPi4 for their setup.

Another update to my original post regarding the secondary monitor. That said, the RPi4 seems faster all around, even with this issue.
