• Cannot read property 'isStream' of undefined with fluent-ffmpeg

  17 juin 2024, par Dario Rusignuolo

  I have these lines of code

  



  s3.getObject(getParams, function (err, response) {
        ffmpeg(response.Body)
            .size('640x360')
            .videoFilter({ filter: 'scale', options: [640, -1] })
            // .seekInput('3:00')
            .duration('0:08')
            .format('mp4')
            .on('error', function (err) {
                console.error(err, 'invalid ffmpeg conversion')
            })
            .on('start', function (start) {
                console.log(start, 'starting');
            })
            .on('progress', function (any) {
                console.log(any, 'progress')
            })
            .on('end', function () {
                s3.putObject({
                    Bucket: S3_CREDENTIALS.bucketName,
                    Key: newKey,
                    Body: fs.readSync(newKey),
                    ContentType: response.ContentType
                }, function (err, data) {
                    fs.unlinkSync(newKey)
                    if (err) {
                        res.json('ko')
                    } else {
                        res.json('ok')
                    }
                });
            })
            .output(fs.createWriteStream(newKey))
            .run()
    })


  



  The reason because I create a file is that I cannot stream the fluent-ffmpeg output to the putObject stream body. Of course if there's a way to avoid to create a local file (and then delete it) is better

  



  The error I get is a fluent-ffmpeg error saying Error [TypeError]: Cannot read property 'isStream' of undefined

  



  Any help is appreciated.

  


• Pass multiple input files to ffmpeg using a single stream in Node

  1er mai 2019, par Matteo Bonacini

  I’m trying to use ffmpeg to merge multiple video files. Every file has the same encoding, and they just need to be stitched together. The problem I’m having is that I’d like to do this using streams, but ffmpeg only supports one input stream per command.

  Since the files have the same encoding, I thought I could merge them into a single stream, and feed it as an input to ffmpeg.

  const CombinedStream = require("combined-stream")
  
  const ffmpeg = require("fluent-ffmpeg")
  
  const AWS = require("aws-sdk")
  
  const s3 = new AWS.S3()
  
  
  
  const merge = ({ videos }) => {
  
    const combinedStream = CombinedStream.create();
  
  
  
    videos //I take my videos from S3 and merge them
  
      .map((video => {
  
        return s3
  
          .getObject({
  
            Bucket: "myAWSBucketName",
  
            Key: video
  
          })
  
          .createReadStream()
  
      }))
  
      .forEach(stream => {
  
        combinedStream.append(stream)
  
      })
  
  
  
    ffmpeg()
  
      .input(combinedStream)
  
      .save("/tmp/file.mp4")
  
  }
  
  
  
  merge({ videos: ["video1.mp4", "video2.mp4"]})

  I was hoping ffmpeg could read the files from the single stream and output them together, but I got this error instead :

  Error: ffmpeg exited with code 1: pipe:0: Invalid data found when processing input
  
  Cannot determine format of input stream 0:0 after EOF
  
  Error marking filters as finished
  
  Conversion failed!

  Can anyone help me ?

• Setting a timeout for av_read_frame

  20 décembre 2014, par user3663917

  I am new to FFMPEG and was trying to do HLS streaming using FFMPEG. When i tried using the function "av_read_frame" it returns a negative value whenever data is not available. Is there some method to make this function wait till some data is received or to make this function wait till a timeout is reached ?
