• Convert mp3/audio source to RTSP or something that is live streamable

  20 mars 2019, par spezticle

  I’ve got an mp3 that’s continually being written to. I’m trying to get some HTML5 tag or something to play this file and it will, but it stops at the end of the file as it was loaded in the moment the webpage was pulled up. If I refresh the page, the new length is reflected but position is lost.

  This is streaming, but not live.

  I’m using ffmpeg to push an audio source from a local computer to a remote web server. That webserver receives the file with ffmpeg and writes it to the mp3. Is there no better way of doing this that isn’t absurdly complicated ?

• Returning ffprobe metadata to another function using fluent-ffmpeg

  28 avril 2021, par noquierouser

  I'm trying to use fluent-ffmpeg's ffprobe to get the metadata of a file and add it to a list, but I want to separate the process of getting the metadata from the method related to checking the file, mostly because the addFileToList() function is quite long as is and the ffprobe routine is quite long as well.

  


  I've tried the following code, but it doesn't give the results I'm expecting :

  


  export default {
  // ...
  methods: {
    getVideoMetadata (file) {
      const ffmpeg = require('fluent-ffmpeg')
      ffmpeg.ffprobe(file.name, (err, metadata) => {
        if (!err) {
          console.log(metadata)  // this shows the metadata just fine
          return metadata
        }
      })
    },
    addFileToList (file) {
      // file checking routines
      console.log(this.getVideoMetadata(file))  // this returns null
      item.metadata = this.getVideoMetadata(file)
      // item saving routines
    }    
  }
}


  


  I've already tried to nest the getVideoMetadata() routines inside addFileToList(), and it works, but not as intended, because the actions are carried, but not the first time, only the second time. It seems to be an async issue, but I don't know how can I tackle this.

  


  What can I do ? Should I stick to my idea of decoupling getVideoMetadata() or should I nest it inside addFileToList() and wrestle with async/await ?

  


• Issue #16

  15 décembre 2013, par Grandt

  Issue #16
  * Fixed : An issue, where PNG images exceeding the maximum specified
  
  sizes were broken during resizing.
  
  * Fixed : Issue #16, where ePub 3 multimedia needed to be added to the
  
  automatic chapter processing.
  
  * Fixed : Potential issue related to Issue #16 with loading large files
  
  from external sources, where these might result in memory errors. These
  
  will now be loaded into a temp file on the server, before being added to
  
  the book.
