[MMM-RTSPStream] - Video Streaming from Live Feeds & Security Cameras

bill22

Hi and good evening!

Looks i get the same as you:

/usr/bin/omxplayer --version

I get:

omxplayer - Commandline multimedia player for the Raspberry Pi

I get:

@bill22
Looks like you are doomed to watch Buck Bunny for the rest of your Magic Mirror life :-)

You did not get an error with — hw in your previous mail.
It did return with the prompt, right ?
You did not have to stop it using control C, I mean to say?
Normally omxplayer exits with: have a nice day ; )

Can you try

/usr/bin/omxplayer --genlog --hw --win '351 968 703 1210' rtsp://192.168.178.1:554/?avm=1&freq=394&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=0&pids=0,16,17,18,20,266,593,594,595,598,1801,1802,1803

And check the log file.

bill22

@evroom

Hopefully not…! we may need to find another one if we cannot fix it… :-)

No i didn’t stop it using control C.

 /usr/bin/omxplayer --genlog --hw --win '351 968 703 1210' rtsp://192.168.178.1:554/?avm=1&freq=394&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=0&pids=0,16,17,18,20,266,593,594,595,598,1801,1802,1803

@bill22

Okay, I think it is stumbling over the ampersands in your RTSP URL.
Try it with the RTSP part single quoted, like:

$ /usr/bin/omxplayer --genlog --hw --win '351 968 703 1210' 'rtsp://192.168.178.1:554/?avm=1&freq=394&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=0&pids=0,16,17,18,20,266,593,594,595,598,1801,1802,1803'

Quotes work in general. Tested it on friend Buck Bunny.

bill22

@evroom

Allright! :thumbs_up:

i have a picture overlay with the omxplayer showing the live stream TV signal!

Unfortunately it runs for a second and stops, continuously . > (buffer, cache,…?)

Audio is not there correctly. It sounds like white noise for a second and stops continuously.

bill22

@evroom

FYI:

/usr/bin/omxplayer --genlog --hw --win '351 968 703 1210' 'rtsp://192.168.178.1:554/?avm=1&freq=394&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=0&pids=0,16,17,18,20,266,593,594,595,598,1801,1802,1803'

@bill22
Getting somewhere.
Now you need to slowly add additional parameters.
Like --live --video_queue 4

bill22

i might be wrong. I added it here and received the error message “…file not found”:

/usr/bin/omxplayer --genlog --hw --win --live --video_queue 4 '351 968 703 1210' 'rtsp://192.168.178.1:554/?avm=1&freq=394&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=0&pids=0,16,17,18,20,266,593,594,595,598,1801,1802,1803'

Do i need to add those parameters somewhere else?

evroom

@bill22

/usr/bin/omxplayer --genlog --hw --live --video_queue 4 --win '351 968 703 1210' 'rtsp://192.168.178.1:554/?avm=1&freq=394&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=0&pids=0,16,17,18,20,266,593,594,595,598,1801,1802,1803'

bill22

@evroom

Thanks!
OK, positive effect on the video, running pretty smooth now!
Audio still missing…

evroom

@bill22
With Buck Bunny you had audio, right?
Audio over hdmi or audio jack?

Try adding --audio_queue 4
Then try removing --hw

bill22

@evroom

yes with Buck Bunny the audio was there.

I use audio over HDMI.

adding

--audio_queue 4

didn’t change the behaviour .

removed

--hw

Audio is working smoothly together with video ! !

evroom

@bill22
Great!!

Now you could try to enable the RTSPStream module again.
Use

url: ''rtsp://192.168.178.1:554/?avm=1&freq=394&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=0&pids=0,16,17,18,20,266,593,594,595,598,1801,1802,1803'',

It can be that you need to play a little.

single quote single quote < url > single quote single quote
double quote single quote < url > single quote double quote
single quote < url with & > single quote

I hope you understand what I mean.

Look at the pm2 log for clues.

Over and out for today.

bill22

@evroom

Thank you very much for your guidance getting it to this point !!!

Great that it is working so far!

Have a good evening and i will follow your recommendations and let you know the outcome!

Bill

evroom

@bill22

Try this

url: 'rtsp://192.168.178.1:554/?avm=1\&freq=394\&bw=8\&msys=dvbc\&mtype=256qam\&sr=6900\&specinv=0\&pids=0,16,17,18,20,266,593,594,595,598,1801,1802,1803',

Perhaps even the ? needs to be escaped

url: 'rtsp://192.168.178.1:554/\?avm=1\&freq=394\&bw=8\&msys=dvbc\&mtype=256qam\&sr=6900\&specinv=0\&pids=0,16,17,18,20,266,593,594,595,598,1801,1802,1803',

@bill22

Here a procedure on how to use omxplayer as an addition to MM (without MMM-RTSPStream).
This is how I use it for my Axis IP cam.
You might need to reposition a few modules to make place for the overlaid stream.

pi@MagicPi:~ $ cd

pi@MagicPi:~ $ vi avm_stream.sh
#!/bin/bash
echo "Starting AVM stream ..."

/usr/bin/omxplayer --genlog --live --video_queue 4 --win '351 968 703 1210' 'rtsp://192.168.178.1:554/?avm=1&freq=394&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=0&pids=0,16,17,18,20,266,593,594,595,598,1801,1802,1803'

pi@MagicPi:~ $ chmod +x avm_stream.sh

pi@MagicPi:~ $ pm2 start avm_stream.sh

i@MagicPi:~ $ pm2 save

i@MagicPi:~ $ pm2 status

Instead of vi you of course can use nano or so.

When it runs you can remove the --genlog option.
And I kind of lost track which exact command worked for you at the end.

bill22

The command working with the omx player is:

/usr/bin/omxplayer --genlog --live --video_queue 4 --audio_queue 4 --win '1 720 503 1010' 'rtsp://192.168.178.1:554/?avm=1&freq=394&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=0&pids=0,16,17,18,20,266,593,594,595,598,1801,1802,1803'

MMM-RTSPStream modification for AVM DVB-C stream.

$ vi ~/MagicMirror/config/config.js

        frameRate: "25",
        protocol: "tcp",


	url: 'rtsp://192.168.178.1:554/?avm=1&freq=394&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=0&pids=0,16,17,18,20,266,593,594,595,598,1801,1802,1803'


$ cd /home/pi/MagicMirror/modules/MMM-RTSPStream

$ cp -p node_helper.js node_helper.js.original 

$ nano node_helper.js

Use [control]- (control minus) and enter 101 to go to line 101

           var args = ["--live", "--video_queue", "4", "--fps", "30",

Change the line to:

          var args = ["--live", "--video_queue", "4", "--audio_queue", "4", "--fps", "25",

Use [control]x and then Y to save the file.

$ pm2 restart mm

$ pm2 logs mm

$ ps -eaf | grep omxplayer | grep -v grep

$ pm2 status

Hi,

Overall it looks good I would say.
The ERR are a concern, but I do not see a connection with RTSP.
Give the /home/pi/.npm/_logs/2019-07-09T20_38_42_696Z-debug.log and /home/pi/.npm/_logs/2019-07-09T20_38_45_348Z-debug.loga clue ?
Or when you restart mm, the newly generated log files ?

With $ ps -eaf | grep omxplayer | grep -v grepand pm2 status, are the PIDs for omxplayer and omx_stream1 stable, or do they change ?

Could you do ?

$ pstree -ap `pgrep omxplayer | head -1`; pstree -ap `pm2 status | grep omx_stream1 | awk '{print $10}'`
