• Video - Could not find tag for codec wavpack in stream #1, codec not currently supported in container Could not write file MKV to MP4 with FFmpeg

  9 janvier, par Theagames10

  Trying to convert an hour long MKV file into an MP4 using FFmpeg, but during the conversion process it keeps giving me this error :

  



  Could not find tag for codec wavpack in stream #1, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument


  



  I have tried to use other converters, but they all have file size limits, It takes to long to convert with Handbrake and VLC. I tried to search for some kind of answer on google, but there has been no forum posts anywhere for a solution to this kind of issue.

  


• Firebase function error : Cannot find ffmpeg

  9 janvier 2020, par Nathan

  I’m using the firebase storage to execute a function when a video gets uploaded to the default bucket, in the function I’m using Ffmpeg to convert the video and set some other options like size, then I want to reupload the file back to storage and I keep getting this error :

  Error: Cannot find ffmpeg

  I have used npm install to install both fluent-ffmpeg and ffmpeg-static yet it says it cannot find it ? Here’s my code :

  const ffmpeg = require('fluent-ffmpeg');
  
  const ffmpeg_static = require('ffmpeg-static');
  
  const {Storage} = require('@google-cloud/storage');
  
  const fs = require('fs');
  
  const os = require('os');
  
  var path = require('path');
  
  
  
  // Creates a client
  
  const storage = new Storage({
  
  projectId: 'projectID',
  
  });
  
  
  
  function promisifyCommand(command) {
  
  return new Promise((resolve, reject) => {
  
    command.on('end', resolve).on('error', reject).run();
  
  });
  
  }
  
  
  
  exports.updatePost = functions.storage.object().onFinalize(async (object) => {
  
  
  
  const fileBucket = object.bucket; // The Storage bucket that contains the file.
  
  const filePath = object.name; // File path in the bucket.
  
  const contentType = object.contentType; // File content type.
  
  const resourceState = object.resourceState; // The resourceState is 'exists' or 'not_exists' (for file/folder deletions).
  
  const metageneration = object.metageneration; // Number of times metadata has been generated. New objects have a value of 1.
  
  
  
  // Get file name
  
  const fileName = path.basename(filePath);
  
  
  
  // Exit if this is a move or deletaion event.
  
  if(resourceState === 'not_exists'){
  
      console.log('This is a deletion event');
  
      return;
  
  }
  
  
  
  // Download file from bucket
  
  const bucket = storage.bucket(fileBucket);
  
  const tempFilePath = path.join(os.tmpdir(), fileName)
  
  // We add a '_output.flac' suffix to target audio file name. That's where we'll upload the converted audio.
  
  const targetTempFileName = fileName.replace(/\.[^/.]+$/, "") + '_output.mp4';
  
  const targetTempFilePath = path.join(os.tmpdir(), targetTempFileName);
  
  const targetStorageFilePath = path.join(path.dirname(filePath), targetTempFileName);
  
  
  
  await bucket.file(filePath).download({destination: tempFilePath});
  
      console.log('Video downloaded locally to', tempFilePath);
  
      // Convert the video to suitable formats
  
      const command = ffmpeg(tempFilePath)
  
      .setFfmpegPath(ffmpeg_static.path)
  
      .withSize('50%')
  
      .toFormat('mp4')
  
      .output(targetTempFilePath);
  
      await promisifyCommand(command);
  
          console.log('New video created');
  
  
  
          //Upload video again
  
          await bucket.upload(targetTempFilePath, {destination: targetStorageFilePath});
  
              console.log('Output video uploaded to', targetStorageFilePath);
  
              // Delete the local file from server as it's been uploaded to storage
  
              fs.unlinkSync(tempFilePath);
  
              fs.unlinkSync(targetTempFilePath);
  
  
  
              console.log('Tempory files removed.', targetTempFilePath);
  
  });

  I have searched everywhere and people are also saying that running the ffmpeg module on the function will also exceed the limit very quickly and where told to use ffmpeg-static instead ?
  Thanks,

  Nathan

• Webhoster can’t find server after outage

  My web hoster can’t find my server anymore after it went down unexpectedly. Since the backup server in the same facility also went down and is also not findable, I have to recover the site from various backups. This could take a moment. Sorry for the inconvenience. UPDATE : I moved to a new (...)
