  • Capturing audio data (using javascript) and uploading on a server as MP3

    4 septembre 2018, par Michel

    Following a number of resources on the internet, I am trying to build a simple web page, where I can go to record something (my voice), then make a mp3 file out of the recording and finally upload that file to a server.

    At this point I can do the recording and also play back, but I haven’t gone as far as uploading, it seems like I cannot even make an mp3 file locally.
    Can someone tell me what I am doing wrong, or in the wrong order ?

    Below is all the code I have at this point.

        
    
    
    
    
    
    
    

    

    
<div>
    
    <h2>Audio record and playback</h2>
    
    <p>
    
        <button></button></p><h3>Start</h3>
    
        <button disabled="disabled"><h3>Stop</h3></button>
    
        <audio controls="controls"></audio>
    
        <a></a>
    
    
    
</div>
    

    
<code class="echappe-js">&lt;script&gt;<br />
    
  var player = document.getElementById('player');<br />
    
<br />
    
  var handleSuccess = function(stream) {<br />
    
    rec = new MediaRecorder(stream);<br />
    
<br />
    
    rec.ondataavailable = e =&gt; {<br />
    
        audioChunks.push(e.data);<br />
    
        if (rec.state == &quot;inactive&quot;) {<br />
    
            let blob = new Blob(audioChunks,{type:'audio/x-mpeg-3'});<br />
    
            player.src = URL.createObjectURL(blob);<br />
    
            player.controls=true;<br />
    
            player.autoplay=true;<br />
    
            // audioDownload.href = player.src;<br />
    
            // audioDownload.download = 'sound.data';<br />
    
            // audioDownload.innerHTML = 'Download';<br />
    
            mp3Build();<br />
    
        }<br />
    
    }<br />
    
<br />
    
    player.src = stream;<br />
    
  };<br />
    
<br />
    
  navigator.mediaDevices.getUserMedia({audio:true/*, video: false */})<br />
    
      .then(handleSuccess);<br />
    
<br />
    
startRecord.onclick = e =&gt; {<br />
    
  startRecord.disabled = true;<br />
    
  stopRecord.disabled=false;<br />
    
  audioChunks = [];<br />
    
  rec.start();<br />
    
}<br />
    
<br />
    
stopRecord.onclick = e =&gt; {<br />
    
  startRecord.disabled = false;<br />
    
  stopRecord.disabled=true;<br />
    
  rec.stop();<br />
    
}<br />
    
<br />
    
<br />
    
var ffmpeg = require('ffmpeg');<br />
    
<br />
    
function mp3Build() {<br />
    
try {<br />
    
    var process = new ffmpeg('sound.data');<br />
    
    process.then(function (audio) {<br />
    
        // Callback mode.<br />
    
        audio.fnExtractSoundToMP3('sound.mp3', function (error, file) {<br />
    
            if (!error) {<br />
    
                console.log('Audio file: ' + file);<br />
    
        audioDownload.href = player.src;<br />
    
        audioDownload.download = 'sound.mp3';<br />
    
        audioDownload.innerHTML = 'Download';<br />
    
      } else {<br />
    
        console.log('Error-fnExtractSoundToMP3: ' + error);<br />
    
      }<br />
    
        });<br />
    
    }, function (err) {<br />
    
        console.log('Error: ' + err);<br />
    
    });<br />
    
} catch (e) {<br />
    
    console.log(e.code);<br />
    
    console.log(e.msg);<br />
    
}<br />
    
}<br />
    
<br />
    
&lt;/script&gt;

    When I try to investigate and see what is happening using the Debugger inside the Web Console ; on the line :

    var process = new ffmpeg('sound.data');

    I get this message :

    Paused on exception
    
TypeError ffmpeg is not a contructor.

    And on the line :

    var ffmpeg = require('ffmpeg');

    I get this message :

    Paused on exception
    
ReferenceError require is not defined.

    Beside when I watch the expression ffmpeg, I can see :

    ffmpeg: undefined

    After some further investigations, and using browserify I use the following code :

        
    
    
    
    
    
    
    

    

    
<div>
    
    <h2>Audio record and playback</h2>
    
    <p>
    
        <button></button></p><h3>Start</h3>
    
        <button disabled="disabled"><h3>Stop</h3></button>
    
        <audio controls="controls"></audio>
    
        <a></a>
    
    
    
</div>
    

    
<code class="echappe-js">&lt;script src='http://stackoverflow.com/feeds/tag/bundle.js'&gt;&lt;/script&gt;
    

    &lt;script&gt;<br />
    
  var player = document.getElementById('player');<br />
    
<br />
    
  var handleSuccess = function(stream) {<br />
    
    rec = new MediaRecorder(stream);<br />
    
<br />
    
    rec.ondataavailable = e =&gt; {<br />
    
        if (rec.state == &quot;inactive&quot;) {<br />
    
            let blob = new Blob(audioChunks,{type:'audio/x-mpeg-3'});<br />
    
            //player.src = URL.createObjectURL(blob);<br />
    
            //player.srcObject = URL.createObjectURL(blob);<br />
    
            //player.srcObject = blob;<br />
    
            player.srcObject = stream;<br />
    
            player.controls=true;<br />
    
            player.autoplay=true;<br />
    
            // audioDownload.href = player.src;<br />
    
            // audioDownload.download = 'sound.data';<br />
    
            // audioDownload.innerHTML = 'Download';<br />
    
            mp3Build();<br />
    
        }<br />
    
    }<br />
    
<br />
    
    //player.src = stream;<br />
    
    player.srcObject = stream;<br />
    
  };<br />
    
<br />
    
  navigator.mediaDevices.getUserMedia({audio:true/*, video: false */})<br />
    
      .then(handleSuccess);<br />
    
<br />
    
startRecord.onclick = e =&gt; {<br />
    
  startRecord.disabled = true;<br />
    
  stopRecord.disabled=false;<br />
    
  audioChunks = [];<br />
    
  rec.start();<br />
    
}<br />
    
<br />
    
stopRecord.onclick = e =&gt; {<br />
    
  startRecord.disabled = false;<br />
    
  stopRecord.disabled=true;<br />
    
  rec.stop();<br />
    
}<br />
    
<br />
    
<br />
    
var ffmpeg = require('ffmpeg');<br />
    
<br />
    
function mp3Build() {<br />
    
try {<br />
    
    var process = new ffmpeg('sound.data');<br />
    
    process.then(function (audio) {<br />
    
        // Callback mode.<br />
    
        audio.fnExtractSoundToMP3('sound.mp3', function (error, file) {<br />
    
            if (!error) {<br />
    
                console.log('Audio file: ' + file);<br />
    
        //audioDownload.href = player.src;<br />
    
        audioDownload.href = player.srcObject;<br />
    
        audioDownload.download = 'sound.mp3';<br />
    
        audioDownload.innerHTML = 'Download';<br />
    
      } else {<br />
    
        console.log('Error-fnExtractSoundToMP3: ' + error);<br />
    
      }<br />
    
        });<br />
    
    }, function (err) {<br />
    
        console.log('Error: ' + err);<br />
    
    });<br />
    
} catch (e) {<br />
    
    console.log(e.code);<br />
    
    console.log(e.msg);<br />
    
}<br />
    
}<br />
    
<br />
    
&lt;/script&gt;

    That solved the problem of :

    the expression ffmpeg being: undefined

    But the play back is no longer working. I may not be doing the right thing with player.srcObject and maybe some other things too.

    When I use this line :

    player.srcObject = URL.createObjectURL(blob);

    I get this message :

    Paused on exception
    
TypeError: Value being assigned to HTMLMediaElement.srcObject is not an object.

    And when I use this line :

    player.srcObject = blob;

    I get this message :

    Paused on exception
    
TypeError: Value being assigned to HTMLMediaElement.srcObject does not implement interface MediaStream.

    Finally, if I use this :

    player.srcObject = stream;

    I do not get any error message but the voice recording still does not work.

  • avfilter/vf_edgedetect : properly implement double_threshold()

    22 juin 2020, par Valery Kot
    avfilter/vf_edgedetect : properly implement double_threshold()

    Important part of this algorithm is the double threshold step : pixels
    
above "high" threshold being kept, pixels below "low" threshold dropped,
    
pixels in between (weak edges) are kept if they are neighboring "high"
    
pixels.
    

    The weak edge check uses a neighboring context and should not be applied
    
on the plane's border. The condition was incorrect and has been fixed in
    
the commit.
