• flient-ffmpeg getting error as "ffmpeg exited with code 1 : pipe:0 : Invalid data found when processing input"

  6 avril 2023, par Abhishek Rawal

  I am trying to create API where i need to get uploaded video and create thumbnail from that video. But conditions are :

  


  

  • Video should not store on local disk

  


  • Once thumbnail is create it should not store on local disk, instead it should directly uploaded to AWS s3 bucket.

  


  


  Following is the code i am trying with :

  


  


  


  const ffmpeg = require('fluent-ffmpeg');
const stream = require('stream');

router.post('/thumbnail', upload.any(), (req, res) => {
  const videoBuffer = req.files[0].buffer;
  
  let readableVideoBuffer = new stream.PassThrough();
    readableVideoBuffer.write(videoBuffer);
    readableVideoBuffer.end()
    
  let bufferStream = new stream.PassThrough();
  
  ffmpeg(readableVideoBuffer)
    .on('filenames', function(filenames) {
      console.log('Will generate ' + filenames.join(', '))
    })
    .on('end', function() {
      console.log('Screenshots taken');
    })
    .on('error', (err) => {
      console.log(err);
    })
    .screenshots({
      count: 4,
      size: '100x100',
      timestamps: ['00:00:01.000'],
    })
    .writeToStream(bufferStream, { end: true });  /* while using this statement i am getting error */
    
    const buffers = [];
    bufferStream.on('data', function (buf) {
      buffers.push(buf);
    });
    bufferStream.on('end', function () {
      const outputBuffer = Buffer.concat(buffers);
      // use s3 bucket code here
      console.log('outputBuffer===========>', outputBuffer)
    });
})

  


  


  



  so while calling this API my app is crashing and i am getting error as :

  


  


  Error : ffmpeg exited with code 1 : pipe:0 : Invalid data found when
processing input

  


  


  Blockquote

  


  If i am not using this statement :

  


  


  .writeToStream(bufferStream, end : true ) ;

  


  


  then able to save file but in local disk, which is not required in my case.

  


  Please help me to understand what is wrong in this code, how i can resolve it.
Any type of help is appreciated.

  


• ffprobe on windows no output beyond " { " (ffmpeg-6.0-essentials_build) (in a python script) [closed]

  7 avril 2023, par Stahkub

  I'm attempting to use ffprobe (in a python script) on an rtsp stream using the following command :

  


  ffprobe -loglevel quiet -rtsp_transport tcp -select_streams v:0 -show_entries stream=width,height -of json rtsp://stream


  


  however the only thing showing in the console after this command is "" on windows, but works on wsl where it produces full json output and not just a single ""

  


  the windows command will never return and must be killed. Any ideas ?

  


  Reinstalled ffmpeg, different versions, rebooted pc, tried absolute path to ffprobe, tried running ffprobe using python. Tried piping output to a file, same result. I've searched around and haven't found a similar issue.
