Setting HTML5 audio position
JavascriptGoogle ChromeHtml5 AudioJavascript Problem Overview
How to jump to certain time offsets in HTML5 Audio elements?
They say you can simply set their currentTime
property (emphasis mine):
> The currentTime
attribute must, on getting, return the current
> playback position, expressed in seconds. On setting, if the media
> element has a current media controller, then it must throw an
> INVALID_STATE_ERR exception; otherwise, the user agent must seek to
> the new value (which might raise an exception).
Alas, it doesn't seem to work (I need it in Chrome).
There are similar questions, although, no answers.
Javascript Solutions
Solution 1 - Javascript
To jump around an audio file, your server must be configured properly.
The client sends byte range requests to seek and play certain regions of a file, so the server must response adequately:
> In order to support seeking and playing back regions of the media that > aren't yet downloaded, Gecko uses HTTP 1.1 byte-range requests to > retrieve the media from the seek target position. In addition, if you > don't serve X-Content-Duration headers, Gecko uses byte-range requests > to seek to the end of the media (assuming you serve the Content-Length > header) in order to determine the duration of the media.
Then, if the server responses to byte range requests correctly, you can set the position of audio via currentTime
:
audio.currentTime = 30;
See MDN's Configuring servers for Ogg media (the same applies for other formats, actually).
Also, see Configuring web servers for HTML5 Ogg video and audio.
Solution 2 - Javascript
Works on my chrome...
$('#audio').bind('canplay', function() {
this.currentTime = 29; // jumps to 29th secs
});
Solution 3 - Javascript
Both audio and video media accept the #t
URI Time range property
> song.mp3#t=8.5
To dynamically skip to a specific point use HTMLMediaElement.currentTime:
audio.currentTime = 8.5;
Solution 4 - Javascript
A much easier solution is
var element = document.getElementById('audioPlayer');
//first make sure the audio player is playing
element.play();
//second seek to the specific time you're looking for
element.currentTime = 226;
Solution 5 - Javascript
Make sure you attempt to set the currentTime
property after the audio element is ready to play. You can bind your function to the oncanplay
event attribute defined in the specification.
Can you post a sample of the code that fails?
Solution 6 - Javascript
I was facing problem that progress bar of audio was not working but audio was working properly. This code works for me. Hope it will help you too. Here song is the object of audio component.
HTML Part
<input type="range" id="seek" value="0" max=""/>
JQuery Part
$("#seek").bind("change", function() {
song.currentTime = $(this).val();
});
song.addEventListener('timeupdate',function (){
$("#seek").attr("max", song.duration);
$('#seek').val(song.currentTime);
});
Solution 7 - Javascript
Firefox also makes byte range requests when seeking content that it has not yet loaded- it is not just a chrome issue. Set the response header "Accept-Ranges: bytes" and return a 206 Partial Content status code to allow any client to make byte range requests.
Solution 8 - Javascript
The @katspaugh's answer is correct, but there is a workaround that does not require any additional server configuration. The idea is to get the audio file as a blob, transform it to dataURL
and use it as the src
for the audio
element.
Here is solution for angular $http
, but if needed I can add vanilla JS version as well:
$http.get(audioFileURL,
{responseType:'blob'})
.success(function(data){
var fr = new FileReader;
fr.readAsDataURL(data);
fr.onloadend = function(){
domObjects.audio.src = fr.result;
};
});
cautions
- This workaround is not suitable for large files.
- It will not work cross-origin unless CORS are set properly.
Solution 9 - Javascript
Set time position to 5 seconds:
var vid = document.getElementById("myAudio");
vid.currentTime = 5;

In order to fix video rewind and fast forward on chrome just add /stream? to your html request for example:

My problem was video rewind and forward didnt work on chrome but worked well on mozzila.
