• error enoent when assigning path to ffmpeg

  12 septembre 2022, par seriously

  I am trying to set up a relay from my rtmp server and I'm using an npm module called node-media-server. I have set up my rtmp protocol successfully but when I am trying to set up the relay it expects me to add a path my my ffmpeg library so i npm installed ffmpeg then supplied the node_module path to the relay but I keep on getting error uncaughtException Error: spawn C:\blah\blah\node_modules\ffmpeg ENOENT the ffmpeg library definitely exist at the specified location. Why is this happening ? Thanks in advance.

  


  Link to the module im using : https://www.npmjs.com/package/node-media-server

  


  


  


  const NodeMediaServer = require('node-media-server');
const path = require('path')
const ffmpegPath = path.join(__dirname, '..', 'node_modules', 'ffmpeg')

const config = {
  rtmp: {
    port: 1935,
    chunk_size: 60000,
    gop_cache: true,
    ping: 30,
    ping_timeout: 60
  },
  http: {
    port: 8000,
    allow_origin: '*'
  },
  relay: {
    ffmpeg: ffmpegPath,
    tasks: [{
        app: 'live',
        mode: 'push',
        edge: 'rtmp://localhost:1936',
      },
      {
        app: 'live',
        mode: 'push',
        edge: 'rtmp://localhost:1937',
      }
    ]
  }
};

var nms = new NodeMediaServer(config)
nms.run();

  Please help with the error, trying to re-encode the source file produced with prores 4444+alpha. Alpha channel is required in my case.

  


  I've tried two separate options, both are erroring out :

  


  $ ffmpeg -i Input.mxf -vcodec prores_ks -profile:v 4 -y Output.mxf 


  


  I'm getting this output

  Above I can't even fully see the error since the red text over black background covers the screen :


  


  I have also tried the following encoding options :

  


   -c:v qtrle -pix_fmt argb 


  


  to which, I'm getting the following error :

  


  track 0: could not find essence container ul, codec not currently supported in container
