  • FFMPEG progress bar in php

    16 mars 2017, par Mick Jack

    I am using ffmpeg to convert a video file large files take a long time to get encode. i will like to show a progress bar with a percentage/time remaining

    i saw and tried this example but for some reason the progress bar is not showing.

    Html form

    <form action="upload.php" method="post" enctype="multipart/form-data">
    
<label for="file"><span></span></label>
    
<input type="file" /> 
    
<br />
    
Please enter video title:
    
<br />
    
<input />
    
<br />
    
<input type="submit" value="Submit" />
    
</form>
    

    
<div title="test">
    
        <h5>Encoding percentage</h5>

  • How to get the correct result file data if I use Web Worker on ffmpeg.js ?

    23 avril 2019, par SuperBerry

    I have tried to use FFMPEG.js (https://github.com/Kagami/ffmpeg.js) to convert mp3 files on the browser/client side, and I followed the usage of the page of Web Worker. However, the worker works well on the converting and it seems the file has been converted, but I cannot get the correct result file data back.

    Here my code is :

    <code class="echappe-js">&lt;script&gt;<br />
    
<br />
    
var stdout = &quot;&quot;;<br />
    
var outputhtml=&quot;&quot;;<br />
    
var stderr = &quot;&quot;;<br />
    
var outputfile;<br />
    
<br />
    
var sampleVideoData;<br />
    
<br />
    
function retrieveSampleVideo() {<br />
    
  var oReq = new XMLHttpRequest();<br />
    
  oReq.open(&quot;GET&quot;, &quot;short.mp3&quot;, true);<br />
    
  oReq.responseType = &quot;arraybuffer&quot;;<br />
    
<br />
    
  oReq.onload = function (oEvent) {<br />
    
    var arrayBuffer = oReq.response;<br />
    
    if (arrayBuffer) {<br />
    
      sampleVideoData = new Uint8Array(arrayBuffer);<br />
    
    }<br />
    
  };<br />
    
<br />
    
  oReq.send(null);<br />
    
}<br />
    
<br />
    
function getDownloadLink(fileData, fileName) {<br />
    
  var a = document.createElement('a');<br />
    
  a.download = fileName;<br />
    
  var blob = new Blob([fileData]);<br />
    
  var src = window.URL.createObjectURL(blob);<br />
    
  a.href = src;<br />
    
  a.textContent = 'Click here to download ' + fileName + &quot;!&quot;;<br />
    
  document.body.appendChild(a);<br />
    
}<br />
    
<br />
    
var worker = new Worker(&quot;ffmpeg-worker-mp4.js&quot;);<br />
    
<br />
    
retrieveSampleVideo();<br />
    
<br />
    
var memfs =[];  <br />
    
<br />
    
//[, {name: &quot;input.mp3&quot;, data: output}];<br />
    
<br />
    
worker.onmessage = function(e) {<br />
    
  var msg = e.data;<br />
    
<br />
    
  switch (msg.type) {<br />
    
  case &quot;ready&quot;:<br />
    
    console.log(&quot;ready: &quot; + msg.data);<br />
    
    alert(sampleVideoData.length);<br />
    
    memfs.push({name: &quot;input.mp3&quot;, data: sampleVideoData});<br />
    
    memfs.push({name: &quot;output.mp3&quot;, data: outputfile});<br />
    
<br />
    
    worker.postMessage({type: &quot;run&quot;, MEMFS: memfs, arguments: [&quot;-i&quot;, &quot;input.mp3&quot;, &quot;-y&quot;, &quot;output.mp3&quot;]});<br />
    
<br />
    
<br />
    
    break;<br />
    
  case &quot;stdout&quot;:<br />
    
    console.log(&quot;stdout: &quot; + msg.data);<br />
    
    stdout += msg.data + &quot;\n&quot;;<br />
    
    outputhtml+=msg.data + &quot;&lt;br&gt;&quot;;<br />
    
<br />
    
    break;<br />
    
  case &quot;stderr&quot;:<br />
    
    console.log(&quot;stderr: &quot; + msg.data);<br />
    
    stderr += msg.data + &quot;\n&quot;;<br />
    
    outputhtml+=msg.data + &quot;&lt;br&gt;&quot;;<br />
    
<br />
    
    break;<br />
    
<br />
    
  case &quot;exit&quot;:<br />
    
<br />
    
    console.log(&quot;Process exited with code &quot; + msg.data);<br />
    
    console.log(stdout);<br />
    
    document.write(outputhtml);<br />
    
<br />
    
    getDownloadLink(outputfile, &quot;output.mp3&quot;);<br />
    
    worker.terminate();<br />
    
<br />
    
<br />
    
    break;<br />
    
  }<br />
    
};<br />
    
<br />
    
    &lt;/script&gt;

    And the console output looks good :

    I have set the output into the memfs in the code :

    memfs.push(name : "output.mp3", data : outputfile) ;

    But I cannot get the result file data in outputfile to create the blob downloadd link.
