• 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 !

  


• Combining audio and multiple videos with FFMPEG [closed]

  6 novembre 2023, par Lee P

  I am working on a ffmpeg script to combine two videos with one audio file. The first video file should start after about 6 seconds and the second after about 40 seconds, and there should be a padding with a black screen between the two videos.
However, it only seems to add the first video clones the final frame as the padding.

  


  Here is my current script :

  


  ffmpeg -i video_0.mp4 -i video_1.mp4 -i audio.mp4 -filter_complex "[0:v] tpad=start_duration=5927ms:start_mode=add:color=black:stop_mode=add:color=black; [1:v] tpad=start_duration=44901ms:start_mode=add:color=black:stop_mode=add:color=blackconcat=n=2" -map 2:a -f mp4 -movflags +faststart composite_recording.mp4


  


  The final video timing should be :

  


  00:00-00:06 — black screen
  
00:06-00:24 — first video
  
00:24-00:40 — black screen
  
00:40-00:48 — second video

  


  I tried setting different values for the tpad start_duration for the second video and expected it to start the second video at around 40 seconds into the audio, however it didn't change anything.
