How to display live video to the node red dashboard and have the ability to simply turn it on and turn it off with either a slide switch or "On" "Off" push buttons

Ok gents, I've been staring at this for a long time now and I have to be missing something critical. I'm wanting to make the push button turn on the camera in one instance.
In another instance I would like to publish "ON" from MQTT and have the camera start streaming.
I've been looking in this thread for some clues/examples/templates to mirror.

I'm wondering if I should use a function and use an "if" statement or some other node.

Here's what I'm working with so far.

So I finally got this working to using Kevin Ā“s nodes.
Only sound is not working. While in VLC player its working fine. Any idea on that ?
( ui_mp4frag has the mute option set to false. That did not change anything compared to setting it to true)

EDIT: Ok, I had to remove the "-an" argument from the ffmpeg spawn node. Now it works like charm.
Tested BartButenaers node to which causes a much bigger delay than the one of Kevin.

Could you post working flow please ?

That's great information on the sound!

To get this work you need to install nodes of Kevin and ARP node:

cd .node-red
npm install kevinGodell/node-red-contrib-ffmpeg-spawn kevinGodell/node-red-contrib-mp4frag kevinGodell/node-red-contrib-ui-mp4frag
npm node-red-contrib-arp

then install ffempeg on your system. (google it!)

Import this flow and edit it at:

  1. function node "setCamId XX:XX......":
    change the mac address to the one of your cam.
    change user login to the one of your RTSP login.
    change password to the one of your RTSP password.

  2. function node "getIpFormMac":
    change the port and address at line 38 to the RTSP url of your cam.

EDIT: DonĀ“t forget to create a tab and group at the dashboard and set it in the ui_mp4frag - node :slight_smile:

Sorry this was directed @jorymathis13

I have a flow that used to work but now (after many things have been updated) the UI_mp4frag node doesn't stop when ffmpg is stopped. I wanted to check how the stop start is working in jorymathis13 flow :wink:

no problem. I think its same as mine since I used his / kevinĀ“s flow in the same way.
You send an JSON object:

{"command":"stop"}

to the ffmpeg (spawn) node. this node will kill the ffmpeg process the way its defined in the node.
(default SIGTERM)

EDIT: Of course you have to use this node to start the cam / process. It will then only remember the process id which is needed to stop the process. Dont use this node to spawn multiple instances. need an extra copy of it for every cam.

The flow I posted above is the working flow. @WhiteLion is correct, I initially got one camera working and then just copied the nodes and changed the rtsp address to match the second camera and it worked.
