I am using the node red image in docker and when running

[ { "id": "f6f2187d.f17ca8", "type": "tab", "label": "Flow 1", "disabled": false, "info": "" }, { "id": "2daebe66eab7d6bc", "type": "inject", "z": "f6f2187d.f17ca8", "name": "Start conversion", "props": [ { "p": "topic", "vt": "str" } ], "repeat": "", "crontab": "", "once": false, "onceDelay": 0.1, "topic": "start_conversion", "x": 260, "y": 320, "wires": [ [ "bfcd1695c47af054" ] ] }, { "id": "e2cfd9118ee0fa29", "type": "inject", "z": "f6f2187d.f17ca8", "name": "Stop conversion", "props": [ { "p": "topic", "vt": "str" } ], "repeat": "", "crontab": "", "once": false, "onceDelay": 0.1, "topic": "stop_conversion", "x": 260, "y": 380, "wires": [ [ "bfcd1695c47af054" ] ] }, { "id": "08b85c516eae4ea0", "type": "debug", "z": "f6f2187d.f17ca8", "name": "debug 388", "active": true, "tosidebar": true, "console": false, "tostatus": false, "complete": "true", "targetType": "full", "statusVal": "", "statusType": "auto", "x": 670, "y": 320, "wires": [] }, { "id": "bfcd1695c47af054", "type": "rtsp2mjpeg", "z": "f6f2187d.f17ca8", "url": "rtsp://xxx:xxx/videoSub", "username": "xxx", "password": "xxx", "rate": "", "quality": "", "resolution": "", "x": 470, "y": 320, "wires": [ [ "08b85c516eae4ea0" ] ] } ]

When running Start conversion I have this error:

Hi @psd24,

This node depends on the rtsp-ffmpeg library, which requires ffmpeg to be installed. I will need to add that to the readme page as a prerequisite.

Can you plean explain a bit more what you problem is:

  1. You were not aware that FFmpeg needs to be installed (in your docker container).
  2. You have already installed FFmpeg (in your docker container), but this node cannot find it.

My problem was the first:

You were not aware that FFmpeg needs to be installed (in your docker container).

psd24 commented 2 months ago

I still have the same error, I don't know how to solve the problem.

psd24 commented 2 months ago

Solved!

I have created a Dockerfile to install the ffmpeg package

FROM nodered/node-red:latest

USER root

RUN apk add --no-cache ffmpeg

USER node-red
