Unsuccessful video streaming - help please :)

mwoodage

Hello, can anyone help, i’ve tried everything i can think of…

I’m getting the following error when i start up Magic Mirror,

Starting stream stream1 with args: [
“–avdict”,
“rtsp_transport:tcp”,
“–win”,
“334, 796, 686, 1038”,
“–live”,
“–video_queue”,
“4”,
“–fps”,
“30”,
“rtsp://admin:*******@192.168.1.77:554//h264Preview_01_main”
]
Starting PM2 for omx_stream1
PM2 started for omx_stream1
Whoops! There was an uncaught exception…

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues
Stopping stream stream1
Stopping PM2 process: omx_stream1

Any help would be gratefully received.
Thanks

@mwoodage
Do you have the parameter “omxRestart” in your MMM-RTSPStream config ?
I assume you are using this module.
If yes, I would try to comment out (//) this parameter.
Or set it to 0 (omxRestart: 0,).

Hi evroom, thanks for the help - I’ve searched for “omxRestart” in the config but found nothing. :(

@mwoodage There are some issues with the latest release of that module. Please try reverting to an older version and see if it works. I am in the process of working on a fix for it:

cd ~/MagicMirror/modules/MMM-RTSPStream
git checkout f583553

mwoodage

Thanks @shbatm - that’s cured the errors but i’m still not getting the video feed. It could be my settings so will try that first and report back.

Thanks again
Martin

@mwoodage Make sure you can reach the stream in VLC or something similar first. Then try using the args that were spit out in the log to run omxplayer by itself from the command line. You may have to play with the arguments until you can get it work by itself, then you can change the module settings to match.

omxplayer –avdict rtsp_transport:tcp –win 334 796 686 1038 –live –video_queue 4 –fps 30 “rtsp://admin:*******@192.168.1.77:554//h264Preview_01_main”

A few hours ago I was busy with this module too, as it stopped to work after I loaded the latest changes.
I deleted and re-installed the module again; am on the origin/master branch.
For me, the stream only started after this command:

pm2 start omx_stream1

Perhaps worth a try.

With

pm2 list

you can see if omx_stream1 is online.

Then I saved the pm2 config to make it boot resistant

pm2 update
pm2 save

Btw, I do not see the

Starting stream stream1 with args

in the pm2 logs anymore.

Thanks shbatm - i’ve tried the stream several times on my laptop and it shows up without any problems. I’ve now installed VLC player on the Raspberry Pi and i can’t get the feed to work. I’m using exactly the same on both - any ideas?

hi evroom, thanks for the help,
I tried what you said (after installing PM2!) but i just get the following:-

pi@raspberrypi:~ $ pm2 start omx_stream1
[PM2][ERROR] script not found : /home/pi/omx_stream1
script not found : /home/pi/omx_stream1
┌──────┬────┬──────┬────────┬───┬─────┬────────┐
│ Name │ id │ mode │ status │ ↺ │ cpu │ memory │
└──────┴────┴──────┴────────┴───┴─────┴────────┘
Use pm2 show <id|name> to get more details about an app
pi@raspberrypi:~ $

Is that right?? I’m assuming not, as its saying script not found. I’ve un-installed omx player and re-installed it but get the same results.

Sorry, i’m completely new to this so please be patient with me :)

evroom

Did you setup auto start according to this procedure?

https://github.com/MichMich/MagicMirror/wiki/Auto-Starting-MagicMirror

Perhaps it worked for me because the omx_stream was already known by pm2 in my case.
Perhaps it needs to run once for pm2 to be useful.
No idea.

pm2 list

Only shows mm, or MagicMirror?
