• Trouble Executing ffprobe Binary in Node.js on Local Machine

  19 août 2023, par dzul.stellar

  I'm facing an issue executing the ffprobe binary within a Node.js script on my local machine. I have a Node.js script that uses the fluent-ffmpeg library to extract video metadata using ffprobe. While I can execute the ffprobe binary directly from my terminal and retrieve the expected output, I'm encountering issues when attempting to run it within my Node.js script.

  


  Project Structure :

  


  project-root/
├── assets/
│   └── video.mp4
├── node_modules/
├── src/
│   └── index.js
├── layers/
│   └── ffmpeg/
│       └── ffprobe   <-- This is the binary I'm trying to execute
├── package.json
├── package-lock.json


  


  Example Code :

  


  const { exec } = require('child_process');
const binaryPath = './layers/ffmpeg/ffprobe';

exec(binaryPath, (error, stdout, stderr) => {
    if (error) {
        console.error(`Error: ${error.message}`);
        return;
    }

    console.log('Command executed successfully');
    console.log('stdout:', stdout);
    console.error('stderr:', stderr);
});


  


  Error Message :

  


  Error: Command failed: ./layers/ffmpeg/ffprobe
./layers/ffmpeg/ffprobe: ./layers/ffmpeg/ffprobe: cannot execute binary file


  


  Troubleshooting :

  


  

  1. Ensured that the ffprobe binary has executable permissions using chmod +x.

  


  2. Verified that the architecture of the ffprobe binary is arm64, which matches my local system.

  


  3. Checked that the path to the binary is correct and doesn't contain special characters.

  


  4. Tested the basic execution of ffprobe using the exec function, but it still fails.

  


  


  ---

  


  I've tried various troubleshooting steps, including verifying permissions, checking the architecture, and testing basic execution. Despite these efforts, I'm still unable to execute the ffprobe binary within the Node.js environment. I expected the script to successfully run the ffprobe binary and provide the expected output, just like when I run the binary directly from the terminal.

  


  Could anyone provide insights into why the ffprobe binary fails to execute within the Node.js environment, even though it works perfectly when executed from the terminal ? Are there any additional considerations I might be missing ?

  


  Thank you for your help !

  


• Android NDK. How to play video.

  4 février 2014, par bukka.wh

  I need to play video on Android device (different formats). As I have understand, the best way is to use Android NDK with specific libraries that can play video. I have done some basic examples to understand NDK usage, but I don't know what to do next. As I have understood, I must install ffmpeg first of all.
  So I have the following questions given below :

  1. I need to have ffmpeg (the best way is to use Linux, not Windows,
     because in Windows there are some troubles with its installation).
  2. How to play sound of video ?
  3. I have read that some open-source libraries can play video without any efforts. My job is to give them byte-array or path to video on SD. Is this right ?

  So, can anyone help me and explain basic ways how to play video with ndk, may be some basic plan or links ?
  Thank you very much for interest to my question !

• Remove alternate demo versions.

  Remove alternate demo versions.
  jQuery UI and Angular 1 are obsolete.
  
  The basic and basic plus versions are nice to have, but add unnecessary maintenance overhead.
