• How to add an album cover to an mp3 stream using FFmpeg ?

  29 décembre 2022, par Daniel LAPIDES

  I'm having a bit of an issue and I'd really appreciate it if I could get some insights.

  



  What I am trying to do is to add an album cover to the mp3 file that will be downloaded from the front-end.

  



  Context

  



  I'm downloading a video stream from YouTube and converting it to mp3 using fluent-ffmpeg.
  
To get the video I use the ytdl npm module.

  



  I then pipe this stream to the front-end.

  



  What I've found

  



  fluent-ffmpeg offers either pipe() or saveToFile().

  



  What I figured is that when I use the saveToFile() function and actually save my stream into an mp3 file, it works, I do get the album cover.

  



  But when I pipe the stream to front-end or even into a file, the song is saved properly into a file but without the album cover.

  



  Here is my code

  



  Back-end (NodeJS)

  



  let video = ytdl(`http://youtube.com/watch?v=${videoId}`, {
  filter: (format) => format.container === 'mp4' && format.audioEncoding,
  quality: 'lowest'
});

let stream = new FFmpeg()
  .input(video)
  .addInput(`https://i.ytimg.com/vi/${videoId}/default.jpg`)
  .outputOptions([
      '-map 0:1',
      '-map 1:0',
      '-c copy',
      '-c:a libmp3lame',
      '-id3v2_version 3',
      '-metadata:s:v title="Album cover"',
      '-metadata:s:v comment="Cover (front)"'
  ])
  .format('mp3');


  



  And then piping it to my front-end.

  



  stream.pipe(res);
stream
  .on('end', () => {
    console.log('******* Stream end *******');
    res.end.bind(res);
  })
  .on('error', (err) => {
    console.log('ERR', err);
    res.status(500).end.bind(res);
  });


  



  Front-end (React)

  



  axios.get(url)
  .then(res => {
    axios(`${url}/download`, {
      method: 'GET',
      responseType: 'blob'
    })
      .then(stream => {
        const file = new Blob(
          [stream.data],
          { type: 'audio/mpeg' });
        //Build a URL from the file
        const fileURL = URL.createObjectURL(file);
      })
      .catch(err => {
        console.log('ERROR', err);
      });
    })
    .catch(err => {
      console.log('ERROR', err);
    });

• How to add cover art to MP4 ?

  27 décembre 2018, par Ceetch

  I’m trying to find an effective way to update the metadata for my MP4 files that I plan to put on a DLNA server. First thing, I want to have the video files have a cover art.

  I’m specifically using 640x360 JPG files to be the cover art.
  I might also want to add some other tags, like media type or update the Title. Please let me know what can be done.

  If code suggestions are available, please know I have the file name details in a variable %file% to handle things. The JPG has the same name as the source MP4 file, so it’s easy enough to get the file type and remove the extension, which is what I’ve done so far.

  My goal is to be able to simply drop the MP4 file on the following batch file and know its filename and full path, the JPG file, and attach it to the orgininal MP4 file. Apparently ffmpeg.exe won’t write to the file it pulled from, so I have it go to a temp file and then use MOVE to replace the old file with the fixed file.

  @ECHO OFF
  
  set arg=%1
  
  set file=%arg:~1,-5%
  
  ffmpeg -i "%file%.mp4" -i "%file%.jpg" -acodec copy -vcodec copy -map 0 -map 1:0 "%file%WIP.mp4"
  
  move /Y "%file%WIP.mp4" "%file".mp4"

  This code did not seem to work. It doesn’t show up in Windows as the cover art, so I’d say it failed.
