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

imdickie

Great module. Allows my family to see the front door as they walk to answer it.

I am trying to use multiple streams so it shows the camera on my driveway and front door side by side. The layout is setup but, it duplicates the camera feed listed under stream1.

What is the reason why it is not seeing the second stream?

I’ve validated my RSP 3 can see both rtsp streams. In fact, if I swap the ip addresses my MM still shows just the first one listed.

Here is the code I am using.

{
module: 'MMM-RTSPStream',
position: 'bottom_center',
config: {
	autoStart: true,
        rotateStreams: false,
        rotateStreamTimeout: 10,
        showSnapWhenPaused: false,
        moduleWidth: 704,
        moduleHeight: 240,
	localPlayer: 'omxplayer',
        	stream1: {
                name: 'Front Door',
                url: 'rtsp://xxxxx:xxxxx@192.168.1.164:554/Streaming/Channels/102/',
                snapshotUrl: '',
                snapshotRefresh: 10, // Seconds
                frameRate: "30",
                port: 9999,
		width: "320",
		height: "240",
		},
                stream2: {
                name: 'Front Door',
                url: 'rtsp://xxxxx:xxxxx@192.168.1.163:554/Streaming/Channels/102/',
                snapshotUrl: '',
                snapshotRefresh: 10, // Seconds
                frameRate: "30",
                port: 9999,
		width: "320",
		height: "240",
                }
            }
        },

Here is the result:

@imdickie I’d be happy to take a look. First thing to try: change the name property of the second stream so it is different from the first one and see if that fixes it. In your config above, both are name: 'Front Door'

imdickie

@shbatm Thanks for the quick response. I changed them both to the correct names. Same result though, one stream in both windows.

@imdickie OK, couple more things to try:

Make sure you are actually on the wip branch to use OMXPlayer:
- Run cd ~/MagicMirror/modules/MMM-RTSPStream/ && git status and the first line should say: On branch wip. If it says On branch master then run git checkout wip to switch.
Change the port setting of stream2 to port: 10000 (or some other free port, different than stream1 – this shouldn’t matter when using omxplayer, but if it works it means there’s probably a bug I need to fix.
Can you please restart the MM2 script and post (or send in a chat) your Mirror’s server log–e.g. the output to the console/log file and not the DevTools/browser?
- If you’re using pm2 to run the MM script, this would be in ~/.pm2/logs/ on a RPi or run pm2 restart mm && pm2 logs mm
- I’m looking for any errors and the lines that start with “Starting WebSocket server on port…” and “Starting stream stream1 with args…”

imdickie

@shbatm Changing the ports did allow me to see separate streams.

However, when I did the && git status command it did come up On Branch Master so I ran git checkout wip. When I kicked off the MM script after that change my screen just goes black. I went back to master with the different port numbers for now.

I am not running pm2. I can rebuild from scratch and set it up though. This is all pretty new to me and I am learning as I go.

Ctl+q doesn’t stop MM when in the black screen. I had to alt+tab to the console window and ctl+c to stop the script.

Below is the console from when I ran the MM script and it went to a black screen. Hopefully that gives you some idea what is going on.

Thanks again for the help.

@imdickie If you were on the Master branch it makes sense now why you were getting duplicate views, it was using ffmpeg and looking at only the first port for both cameras. The work-in-progress branch does not use websockets/ports for local playback since OMXPlayer just draws directly on top of the MM’s browser window.

For the black screen: I forgot the wip branch has an additional node package required. This should take care of your problem:

cd ~/MagicMirror/modules/MMM-RTSPStream
git checkout wip
git pull
npm install

You may or may not need to also add a moduleOffset config option: see the posts above for pictures, if the video doesn’t line up with the border, you can add moduleOffset: X to shift the video over (where X is a number of pixels).

For more information about the wip branch, there is an updated README on the Github page: https://github.com/shbatm/MMM-RTSPStream/tree/wip

For pm2: it’s definitely not a requirement, but I find it’s nice to have; I included in the note above just in case you were already using it. It will automatically run the MM script for you on startup. See this page if you want more information.

To all using the module: Thanks for bearing with me, I haven’t had a lot of time this past month to finish out the hardware-accelerated version (wip/development branch) but I hope to get it done in the next month or so. I really do appreciate any feedback / issues you have to help me improve this module.

That did it. Thanks a ton.

Not sure if it is omxplayer or not, but the stream seems to be much clearer. There is definitely less lag.

Excellent work, thanks again.

I read through everything I can find and am stuck at the final setting. Can you provide the exact syntax for for the moduleOffset setting?

I tried several iterations and finally got it to shift, but it shifts an equal amount vertically and horizontally.

First I tried this:

moduleOffset:
     {
     top: x
     right: x
     bottom: x
     left: x
     },

and that put the video smack dab in the center and flipped between the two streams.

Then I tried this:

moduleOffset: -20,

and it shifted the video up and left 20 pixels.

What I am trying to accomplish is shift the videos up but stay the same left/right.

Thanks.

@imdickie The 2nd one was the correct method. I made an adjustment to the code so now you can specify separate vertical & horizontal offsets.

// Both methods below should work now:

// Same Offset for Horizontal & Vertical:
moduleOffset: -20    // any number works
// Different Offsets for Horizontal & Vertical:
moduleOffset: { top: -20, left: 0 }

I didn’t get a chance to double check on my mirror, so please pull the update and let me know if you have any issues:

# Run the following to update the module
cd ~/MagicMirror/modules/MMM-RTSPStream
git pull

If you want to make any further adjustments yourself without waiting for me, see this post above on where to edit the code directly.

I was able to get the overlay to match perfectly without using the moduleOffset variable by setting the module to the bottom bar.

It offsets when I positioned it other spots. Also, since you are working on this I noticed when the RTSPStream module is placed near another module that can shift in size like newsfeed it will sift the overlay. That was why I thought to place it in the bottom bar so it became the anchor in the bottom justification.

Thanks again for a great module. It really helped with the wife acceptance factor.
