• Bad argument for fluent-ffmpeg video compression at ChildProcess.spawn()

  22 novembre 2018, par Just A Bad Programmer

  I am using fluent-ffmpeg library in node.js in Firebase for compressing videos uploaded by users through an android app, but the following code yield an error :

  ffmpeg(tempFilePath).videoBitrate('1000k', true)
  
                        .on('error', function(err) {
  
                          console.log('An error occurred: ' + err.message);
  
                        })
  
                        .on('end', function() {
  
                          console.log('Processing finished !');
  
                        })
  
                        .save(compressedVideoFilePath);

  The error is :

  TypeError: Bad argument

  The tempFilePath is from downloading the user uploaded file onto the temp folder of firebase (/tmp/test-4d68b02f-a6ef-4ff3-a5c9-52687fd3f0c4.mp4) :

  const tempFilePath = path.join(os.tmpdir(), filePath);
  
  destBucket.file(filePath).download({
  
            destination: tempFilePath // Download the file to destFilePath
  
          }

  While the compressedVideoFilePath is the destination I want the compressed file to be saved (/tmp/compressed-test-4d68b02f-a6ef-4ff3-a5c9-52687fd3f0c4.mp4) :

  var compressedVideoFilePath = path.join(path.dirname(tempFilePath),"compressed-" + path.basename(tempFilePath));

  After the compressed file is saved, I would upload the file to firebase storage with (But probably this is not the place that caused the error) :

  destBucket.upload(compressedVideoFilePath, {
  
      destination: 'compressed-' + path.basename(filePath),
  
      metadata: metadata
  
    })

  I don’t know how to fix it, any one knows why this keeps happening ? Thanks. :)

• ffmpeg Unrecognized option...Error splitting the argument list : Option not found

  13 juillet 2013, par Ian Zane

  This is probably a pretty simple question for those of you who use ffmpeg, but I'm very new at it, and I'm using it on Windows, which apparently isn't the norm.

  From cmd, with my environment variable set at my ffmpeg install directory, I'm running

  ffmpeg -i C:\Users\Me\Videos\InputVideo.wmv
  
  -vcodec libx264 -acodec aacenc C:\Users\Me\Desktop\OutputVideo.mp4

  (My actual script doesn't have a line break, I just put that there to make reading easier)

  and ffmpeg is throwing

  Unrecognized option 'i C:\Users\Me\Videos\InputVideo.wmv
  
  -vcodec libx264 -acodec aacenc C:\Users\Me\Desktop\OutputVideo.mp4'.
  
  Error splitting the argument list: Option not found.

  Is something wrong with my script ? Am I calling an encoder that isn't currently on my machine ? Is it something to do with the file paths ?

  Thanks for the help, everyone.
