@richland007
I re-read your first post and your problem is more restarting then actual crashing.
Of course a restart can be caused by a crash …
MMM-WatchDog tends to restart MM, so I too would suggest to remove this module.
In principle all it does is sending a ping and restarting MM using pm2 when a timeout occurs.
I also would expect to see some lines in the pm2 logs on WatchDog.
Can you do ?:

pi@MagicPi:~ $ grep -i watchdog /home/pi/.pm2/logs/mm-out.log
pi@MagicPi:~ $ grep -i watchdog /home/pi/.pm2/logs/mm-error.log

What is alo a good package to install is sysstat:

pi@MagicPi:~ $ sudo apt-get install sysstat

This allows for commands like iostat and sar.

vmstat 10 10
iostat 10 10
sar 10 10

Ha ha, not that great, my MM is as slow as a turtle again.
The used swap on my USB stick in the meanwhile is 1GB.
Cannot use any commands to investigate further.
Not very satisfactory. :frowning_face:

@richland007

Then let’s give it a try :slightly_smiling_face:

First create the script:

pi@MagicPi:~ $ cd
pi@MagicPi:~ $ nano top.sh

Copy-paste this:

!/bin/sh

date >> /home/pi/top.txt
top -b -o +%MEM | head -n 22 >> /home/pi/top.txt
top -b -o +%MEM | head -n 22 >> /home/pi/top.txt
echo "=============================================" >> /home/pi/top.txt

Make it executable:

pi@MagicPi:~ $ chmod 755 top.sh

Perhaps a good idea to prepare the output file in order to be sure the cron user can write in it:

pi@MagicPi:~ $ touch /home/pi/top.txt
pi@MagicPi:~ $ chmod 666 /home/pi/top.txt

Now we add a cronjob:

pi@MagicPi:~ $ crontab -e

Add this line at the end:

00,05,10,15,20,25,30,35,40,45,50,55 * * * * /home/pi/top.sh >/dev/null 2>&1

To verify:

pi@MagicPi:~ $ crontab -l

To verify if the cronjob is actually running:

pi@MagicPi:~ $ tail -F /var/log/syslog

To check if something comes in your output file:

pi@MagicPi:~ $ tail -F top.txt

The script will run every 5 minutes, every hour, every day.
It will output the top 15 MEMory usage and the top 15 CPU usage.

In your case, it will be interesting to look at the last entries before the crash.
Need to identify first if it is an CPU or MEM issue, or both.
Then we can modify the script.

Please do not post lengthy output.
Better we minimise the output by grepping and sorting, etc.

Success!

@richland007
Since you managed to setup MM to the point that it is running, but crashing, I take it you know a little bit of Linux.
Otherwise it will be more like a Linux workshop.

Do you know how to use nano and/or vi to edit files?
Know what for example cat, tail and head does?
Just some Linux basics.

I do not want to sound like a smartarse and knowitall, am a hobbyist just like you.
Just to know the level of describing that is needed.

Hi,

Investigating crashes and freezes, etc, can be very difficult.
When everything is running fine and you collect data, you will see that everything is more or less okay.
When it crashed or is frozen, you are too late.

Since a few weeks I had the problem that my MM was frozen and I could not enter any commands or a command took painstakingly long to return output.
A command like top was out of the question for example.
Using a script running as a cron job, I was able to identify a memory issue with electron.js.
I then decide to use a usb stick on which I created a swap device.
Since then my MM is not freezing anymore.
And I am able to see electron.js using up my memory and sometimes I see spikes in CPU usage.

Mind you, that crashing is something different then freezing, but the tools to use are more or less the same, provided the MM application or a MM module is not the culprit.

My script to check memory usage, very basic and simple:

pi@MagicPi:~ $ cat top.sh
#!/bin/sh

date >> /home/pi/top.txt
top -b -o +%MEM | head -n 22 >> /home/pi/top.txt
echo "=============================================" >> /home/pi/top.txt

The cron job:

00,05,10,15,20,25,30,35,40,45,50,55 * * * * /home/pi/top.sh >/dev/null 2>&1

%CPU will sort on CPU usage.

Concerning swap space, top will show the usage, but this gives a quick view:

$ free -h

Swap details via:

$ swapon -s

There are many more commands and settings to look at, but one has to start somewhere :-)

Good luck.

@Cr4z33, no, sorry, didn’t pursue this as I do not need such a function myself.

Some times Google is your friend:

custom.css

.MMM-HTMLBox {
font-size: 18px;
line-height: 22px;
}

Module: MMM-HTMLBox
I want to use this simple but useful module, but how can I change font size for this module ?

I tried the custom.css

.MMM-HTMLBox {
font-size: 12px;
}

That does work, but now the spacing is rather large.
The module itself does not have a css file.

Someone who can guide me a bit ?

Btw, a simple restart of MagicMirror solved the issue and my MM is working again.
Web search tells me that:

gnutls_handshake(): This function performs the handshake of the TLS/SSL protocol, and initializes the TLS session parameters.

Looks to be related with git, as all calls were done to github.com.

Hi,

This morning my MM showed a black screen and the pm2 log says following:

/home/pi/.pm2/logs/MagicMirror-error.log last 15 lines:

I did a search in the forum, but I could not find any other occurrences.
Will search the web now to see if I can find something more on this topic.
In the meantime any clue as to what happened is welcome.

I can stream full HD at 50 fps:

Video codec omx-h264 width 1920 height 1080 profile 100 fps 50.000000

A bit odd.

RAI 3 HD probably is not free-to-air, so I cannot check it.

But to be honest, it seems NOT to work for me too.
Only SD, no HD.
I had it working on v2.4.1 (made notes about it to not to forget) and did not use it after that.

You can test it directly, without having to change the MM config all the time:

$ omxplayer --win "0 0 800 480" --live "http://192.168.1.6:8001/1:0:1:D4B:8800:13E:EEEE0000:0:0:0:"

$ omxplayer --win "0 0 800 480" --live "http://192.168.1.6:8001/1:0:1:2191:5:13E:EEEE0000:0:0:0:"

omxplayer will show the stream details:

Video codec omx-mpeg2 width 720 height 576 profile 4 fps 25.000000
Video codec omx-h264 width 1920 height 1080 profile 100 fps 50.000000

On my Pi it seems to run, but nothing appears on the screen.
:-(

Hi,

Can you check this ?

$ vcgencmd codec_enabled MPG2

It should say “MPG2=enabled”.

License can be bought for a few euro’s:

@Cr4z33,

You can put the code end the end of the file, so after the body stuff.
If you are not familiar with vi, you can use nano:

$ nano /home/pi/MagicMirror/css/custom.css

I have made some changes in the body part, to change the screen margins, etc.

body {
       margin: 10px;
       height: calc(100% - 10px);
       width: calc(100% - 10px);
}

Hi,

Try this:

# vi /home/pi/MagicMirror/css/custom.css
:
:
.MMM-RTSPStream .innerWrapper {
  border-style: none;
}

# pm2 restart MagicMirror

I would still try to have the video window and the module window overlap each other, as it perhaps may influence the position and aligning of other modules.

Hi,

I remember it took me quite a while to have it to my likings (size and position of the window(s)).
The width and height of the stream defines the size of your video.
The width and height in the config defines the place of the stream and what you actually see.
A bit difficult to explain.
Works like a “sjabloon”, template.

Could you show your MMM-RTSPStream config settings and also a part of the ‘pm2 logs MagicMirror’ output ?
Where it says: “Starting stream stream1 with args: [”.

Hi @surger13 ,

You do not have the api_key specified.
The README says:

api_key: false,

But for me this does not work.
I registered at https://www.football-data.org/client/register and the resulting api_key is working fine.

api_key: 'xxxxd62e29754e10b56029399458xxxx',

This is a fake key, use the one you get after registering.

Good luck.

@Cr4z33
Please find below an example for streaming from an Enigma2 box.
The most important line is the url.
The other lines are custom-made for my 2 camera streams.
The url is taken from VLC, which I use to stream SAT TV to my PC.

A few remarks on what I experienced:

For Raspberry Pi, you may need the MPG2 license in order to be able to stream the satellite TS stream.

The Raspberry Pi 3 Model 3 and omxplayer can only handle 1 TS stream, as it appears to be the case.
And a maximum 3 RTSP camera streams.
Perhaps more powerful HW can handle more.

I did not look into the possibility of choosing between streams / channels.
This needs some additional programming or even forking the code to make it specific for TS streams.

Hope it helps.

config.js :

{
  module: "MMM-RTSPStream",
  disabled: false,
  position: "middle_center",
  header: "Axis Security Monitor",
  config: {
    autoStart: true,
    rotateStreams: false,
    moduleWidth: 900,
    moduleHeight: 364,
    localPlayer: 'omxplayer',
    remotePlayer: 'none',
    showSnapWhenPaused: false,
    remoteSnaps: false,
    stream1: {
    name: 'SAT-TV',
    url: 'http://192.168.178.28:8001/1:0:19:2B66:3F3:1:C00000:0:0:0:', // ZDF HD
      protocol: "tcp",
      width: 590,
      height: 332
    },
  }
},

@strawberry-3-141
Thanks, works like a charm.

Any possibility to introduce a rotation option, in order to rotate the standings of the leagues in “show” or “leagues” ?

Hi,

Great job on version 2.0.
I have it running.
Added Eredivisie and some logos; all fine.

Just one question.
In your example your header is left aligned and shows “1. BUNDESLIGA 2015/16”.
Not updated to show the version 2.0 example.
When I choose the Bundesliga I just get “BUNDESLIGA” and it is right aligned.
How do I get it at least left aligned ?
I tried adding this to the custom.css, but it doesn’t work:

.MMM-soccer .header {
    text-align: left;
}
