• Error : Error : Cannot find module '@ffmpeg.wasm/core-mt' Require stack :

  30 septembre 2023, par James

  I'm getting this error "Error : Error : Cannot find module '@ffmpeg.wasm/core-mt', When my code is deployed on Vercel (Node.js + TypeScript) Does I get confused because when I try to run the same code on my local machine it works fine

  


  But as I deploy it on Vercel it gives that error. Obviously, i do have "@ffmpeg.wasm/core-mt" installed as said in the package https://github.com/FFmpeg-wasm/FFmpeg.wasm#installation So how do I fix it ?

  


  I'm currently using it like this

  


  import { FFmpeg } from "@ffmpeg.wasm/main";

async function myFunction() {
    const ffmpeg = await FFmpeg.create({
        core: "@ffmpeg.wasm/core-mt",
        log: true,
    });
}


  


  However, in the docs, i see doing like this

  


    import { FFmpeg } from "@ffmpeg.wasm/main";
    
     const ffmpeg = await FFmpeg.create({
            core: "@ffmpeg.wasm/core-mt",
            log: true,
        });

    async function myFunction() {
        // use ffmpeg here
    }


  


  But then i start getting errors like "top-level 'await' expressions are only allowed when the 'module' option is set to 'es2022', 'esnext', 'system', 'node16', or 'nodenext', and the 'target' option is set to 'es2017' or higher."

  


  I tried a couple of StackOverflow solutions but nothing works in my case. So what should I do ?

  


  tsconfig.json :

  


  {
    "compilerOptions": {
     "module": "CommonJS",
     "esModuleInterop": true,
      "allowSyntheticDefaultImports": true,
      "target": "es2017",
      "noImplicitAny": true,
      "moduleResolution": "node",
      "sourceMap": true,
      "outDir": "dist",
      "baseUrl": ".",
      "paths": {
        "*": ["node_modules/*", "src/types/*"]
      }
    },
    "include": ["./src/**/*", "src/firebase/serviceAccountKey.ts"]
  }


  


• No module named 'skvideo.io.ffmpeg' in the project

  12 juillet 2024, par kyobo

  Even though I have installed the scikit-video and installed ffmpeg, I still meet this problem :
  
No module named 'skvideo.io.ffmpeg

  


  Output :

  I have tried to upgrade pip and skvideo but it doesn't work.

  


  How can I solve this problem ?

  


• nginx rtmp-module can't execute ffmpeg

  6 juin 2023, par Nasir

  I am having an issue with nginx-rtmp-module exec ffmpeg command. i have followed the example on 
www.github.com/arut/nginx-rtmp-module

  



  /home/junaid/bin/ffmpeg -f video4linux2 -i /dev/video1 -c:v libx264 -an -f flv rtmp://127.0.0.1:1935/myapp/mystream


  



  the command is working fine in terminal

  



  Config file :

  



  rtmp {
server {
    listen 1935;
    ping 30s;
    notify_method get;

    application myapp {
    live on;
    allow play all;
    exec_static /home/junaid/bin/ffmpeg -f video4linux2 -i /dev/video1 -c:v libx264 -an -f flv rtmp://127.0.0.1:1935/myapp/mystream;      
 }
}


  



  Error log :
http://www.codepad.org/enD4wlZ9

  



  I have tried :

  



  

  • nginx running as root (have permission to execute ffmpeg)

  


  • using ip instead of localhost

  


  • using complete path to ffmpeg

  


  • executing bash file (having ffmpeg and echo commands : echo commands execute just fine) from nginx

  


  



  please help me resolve this issue
