• ffmpeg screen capture using screen-capture-recorder cmd not working in vb

  14 juin 2014, par user3234288

  I’ve started ffmpeg as process in VB but ffmpeg cmd for capturing alone is not working. My code is,I don’t know how to solve the problem, if any help greatly appreciated

  proc.StartInfo.FileName = System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) & "\converter\bin\ffmpeg.exe"            
  
  proc.StartInfo.Arguments = "-f dshow -i video=screen-capture-recorder screen.mp4"
  
  proc.StartInfo.UseShellExecute = False
  
  proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
  
  proc.StartInfo.RedirectStandardInput = True
  
  proc.StartInfo.RedirectStandardOutput = True
  
  proc.StartInfo.CreateNoWindow = True
  
  proc.Start()

• How do I read ffmpeg log with c# ?

  24 septembre 2018, par mr_blond

  I want to make "./ffmpeg -i vid.mkv" command, to get info and then I need to read it in c#.

  Thereby I run ffmpeg as Process :

  var proc = new Process
  
  {
  
      StartInfo = new ProcessStartInfo
  
      {
  
          FileName = "ffmpeg",
  
          Arguments = "-i vid.mkv",
  
          UseShellExecute = false,
  
          RedirectStandardOutput = true,
  
          CreateNoWindow = true
  
      }
  
  };

  Then I try to read id :

  proc.Start();
  
  while (!proc.StandardOutput.EndOfStream)
  
  {
  
      string line = proc.StandardOutput.ReadLine();
  
  }

  At the step

  proc.Start()

  new console window opens and ffmpeg writes log to it. And at the step

  while()

  proc.StandardOutput.EndOfStream becomes true.

  How do I read this log ?

• 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",
