[beta testing] nodes for live streaming mp4

I thought about it but my CSS skills are limited to "Beginner"


This is the DASHBOARD from the node-red-dashboard node. Node-Red can works without DASHBOARD


This is the Node-Red EDITOR where you create your flows

That would be good :+1:

That’s puts you 1 level above me.

Hi @kevinGodell

I'm trying to run the example I shared here @krambriw to stream my ip camera with rtsp through ffmpeg. But in the last node nothing appears in the players section. How could I solve this? .

Thank you.

My guess is that you may have used a shared flow that has data not compatible with the current dev version from github. Also, the payload shows playlists with undefined values in it. The best thing to do is create a new mp4frag and ui_mp4frag and manually set its properties in the admin editor.

p.s. If you share your flow, I can try to clean it up and post it back to you.

Hi @kevinGodell ,

I attached the flow code, have two examples with ui_mp4frag and mp4player, but i cant make work.
If u helpme i aprreciace it

rtsp_stream_ip_camera_examples.json (6 KB)

I changed a couple things to atleast make the players show up in the list. Of course, I cant fully test it since I dont have access to your ip cams. Also, I didnt have up_mp4_player available for testing compatibility. If you are just trying to get your ip cam rtsp stream to play in the browser as mp4 video, we can make this work.

Hi @kevinGodell

First of all thanks for your help. Although now the player options appear, I could not make it work.

from what I read in this conversation. the node does not work for ip cameras that use the h.265 codec, right?
I have the IP camera with the following configuration:

FFMPEG consumes a lot of cpu from the RPi3 B +, the only solution I found was to generate a request loop from @BartButenaers 's Onvif Media node ... and I refresh the image every X seconds through a template node

Do you think there is a solution to be able to see the streaming fluid from the rtsp?

If you can set your ip cam to use h264, then we should be able to re-stream that with minimal cpu load. Anytime you have ffmpeg encode video, such as converting h265 to h264 or h264 to jpegs, etc., there will be a high cpu load if there is not a hardware accelerated codec available.

When I made the underlying mp4frag library (few years back) that is used inside of node-red-contrib-mp4frag, I did not have access to ip cams containing h265 encoded rtsp, and never explored that possibility. And I am not sure about browsers support of h265 encoded mp4. https://caniuse.com/?search=h.265

Hi @kevinGodell ,
I noticed that since I put the last versions of spawn + mp4frag + mp4frag_ui, the video is stretched vertically, to occupy the dimensions of the widget on the dashboard. Is there a setting somewhere to keep the original dimensions of the video?

on the left the elongated rtsp stream. On the right an image captured by a movement of original size

try this :
you have to install in cd .node-red :

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

you have to put the rtsp arguments of your camera in the ffmpeg-spawn node

Yeah sorry, didn’t update the docs for that yet. I recently moved to a class based styling so that the user has more control over the appearance. Look in the head of the html and you will see the style section with video.ui_mp4frag or something like that. You can add a ui node set to global and override the object fit value and add !important after the value. When I get to my computer later I can give a better response.

css property: object-fit
css value: contain or scale-down both seem to keep the aspect ratio

@kevinGodell
In your node ffmpeg-spawn can you, in a next update, remove the kbits/s bitrate: "153.3kbits/s"
so that we can format it to the unit we want as ko/s or mo/s ?
you can say in the notice that this measurement is in kbits/s

Unfortunately, that value is directly generated from ffmpeg. I have found no way to configure it differently. The alternative would be to place a node between ffmpeg and whatever node you normally have set to receive its buffer. Just check the buffer length to calculate the size on your timescale. There might already be a counter node that does that.

Thank you Kevin, I'll figure it out :wink:

Hi Kevin , did you test ffmpeg-spawn with node-red in WIN10
I test quickly and I have an error:


I imagine I need to install FFMPEG, do you have any other tips to make it work?

No, I have only tested on pi 4. You can try to install 1 of the ffmpeg libraries via npm, such as @ffmpeg-installer/ffmpeg, ffmpeg-for-homebridge, or ffmpeg-static, etc (there is probably more).

In the setting.js file, require the dependency in the ffmpeg-spawn config (you might have to test each one for compatibility):

ffmpegSpawn: {
  cmdPath: require('ffmpeg-for-homebridge'),
},

or

ffmpegSpawn: {
  cmdPath: require('@ffmpeg-installer/ffmpeg').path,
},

or

ffmpegSpawn: {
  cmdPath: require('ffmpeg-static'),
},

This will set the path to the node_modules folder and should be seen in the editor as in the text input placeholder:


Leave the value empty so that it uses the default value set in the settings.js file.

:star_struck: nice it's working as you describe :+1:
