I have a (Drupal / but it could be another too) Website with an audio track autoplayed on frontpage. The audio element is in a block somewhere in the footer, on all pages. Trouble now is if someone navigates to another page the track will start again too. Is there a way to solve this? So if a user changes the page the track stays at the position it was.
Something like set currentTime in sessionStore. and get it from there.
<audio id="audioplayer" autoplay>
<source src="<?php print base_path();?>music/TomDay-WhoWeWantToBe.mp3" type="audio/mpeg">
<source src="<?php print base_path();?>music/TomDay-WhoWeWantToBe.ogg" type="audio/ogg">
<source src="<?php print base_path();?>music/TomDay-WhoWeWantToBe.wav" type="audio/wav">
Ihr Webbrwoser unterstützt das Audio-Element nicht.
</audio>
If i do some changes like this <audio id="audioplayer" autoplay preload="auto" src="<?php print base_path();?>music/TomDay-WhoWeWantToBe.mp3">
And use some session set and get Items like:
var audio = document.getElementById('audioplayer');
window.onbeforeunload = function () { var testx = audio.currentTime; testx = testx.toFixed(2); sessionStorage.setItem('sct', testx);}
startPoint = sessionStorage.getItem('sct');
document.getElementById("audioplayer").src = "<?php print base_path();?>music/TomDay-WhoWeWantToBe.mp3#t=" + startPoint + "";
I have a solution that kinda works BUT how can i get this without putting src= into the audiotag itselfs? So i still could have different source src files? and isnt there any simpler way to get that result maybe even better?

Right now I have this

which I have no idea how to make it select each one randomly on page load up, is there a way to like have a list and then make source src choose from a list randomly on each reload? pretty new to html and any help would be much appreciated!! ^^
Like this
https://jsfiddle.net/mplungjan/6opnhymz/
const audioUrls = ["https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3",
"https://www.soundhelix.com/examples/mp3/SoundHelix-Song-2.mp3",
"https://www.soundhelix.com/examples/mp3/SoundHelix-Song-3.mp3"];
const rnd = Math.floor(Math.random()*audioUrls.length); // random number from 0 to length of array
const audio = new Audio(); // an audio object
const loadedAudio = () => audio.play(); // what happens after the audio successfully has been found
document.body.appendChild(audio); // add it to the page
audio.addEventListener('canplaythrough', loadedAudio, false); // add the event that will play, here "can it play?"
console.log(`Playing #${rnd}:${audioUrls[rnd]}`); // for us to see it works
audio.src = audioUrls[rnd]; // actual trigger to play the audio
audio.load(); // iOS may need this
I have this code, but I do not know how to make the song start from 0:19 seconds. Could you help me out?
<div class="fin-subheading">
· ROLEPLAY ·
<audio id='music' volume='0.5' autoplay controls>
<source src="anonymous.mp3" type="audio/mpeg">
</audio>
</div>
<script>
var audio = document.getElementById("music");
audio.volume = 0.3;
</script>
You can specify a playback range in the src attribute itself. See the docs here:
When specifying the URI of media for an or element,
you can optionally include additional information to specify the
portion of the media to play. To do this, append a hash mark ("#")
followed by the media fragment description.
A time range is specified using the syntax:
#t=[starttime][,endtime]
So instead of:
<source src="anonymous.mp3" type="audio/mpeg">
simply put:
<source src="anonymous.mp3#t=n,m" type="audio/mpeg">
where n and m are the start and end times, respectively.
The range can also be unbounded as well. So you could, for instance do this:
<source src="anonymous.mp3#t=19" type="audio/mpeg">
which will start at 19 seconds and play through till the end; or even this:
<source src="anonymous.mp3#t=,19" type="audio/mpeg">
which will start from the beginning through 19 seconds.
You can use currentTime property
window.onload = function() {
const audio = document.getElementById("music");
audio.volume = 0.3;
audio.currentTime = 19;
audio.play();
}
You need to use canplaythrough event and within that currentTime and then play when that time is reached.
Make sure you do not autoplay in the audio tag in HTML.
<audio id="audio2"
preload="auto"
src="http://upload.wikimedia.org/wikipedia/commons/a/a9/Tromboon-sample.ogg" >
<p>Your browser does not support the audio element</p>
</audio>
<script>
myAudio=document.getElementById('audio2');
myAudio.addEventListener('canplaythrough', function() {
this.currentTime = 19;
this.play();
});
</script>
I do found something online that is just about to be similar to what am trying to achieve, but here are a few problems i encountered. (1) i want the time be in minutes and seconds format. (2) the code only works for a single video in my html file. how can i make the code work for multiple videos in my file all showing their different durations. below is the code
<script> var myVideoPlayer = document.getElementById('video_player'), meta = document.getElementById('meta'); myVideoPlayer.addEventListener('loadedmetadata', function () { var duration = myVideoPlayer.duration; meta.innerHTML = "Duration is " + duration.toFixed(2) + " seconds." }); </script>
<video id="video_player" width="320" height="240" controls poster="something/something.jpg"> <source src="someVideo.mp4" type="video/mp4"> </video>
<div id="meta"></div>
This is what I want to achieve using codeigniter
Like this:
<video width="320" height="240" id = "myVideo" controls>
<source src="someVideo.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>
<script>
var e = document.getElementById("myVideo");
var cancelAlert = false;
var run = function() {
if (e.readyState === 4 && !cancelAlert) {//readyState 4 means it is loaded fully
cancelAlert = true;//This is so that it only alerts once. No spam pls.
alert(e.duration);
}
requestAnimationFrame(run);//This is so that it runs every frame.
};
run();//run the function
</script>
You may need to do some tweaking, and there is probably a more efficient way to do this, but this is what I do.
Currently I am using following code to play some audio after a link is clicked:
Pronunciation of a word
For now if the user clicks on the link, a new page with an audio playing panel is loaded. After playing the audio, the user has to click GO BACK button of the browser to get back to the original content.
Is it possible to play the audio without being directed to a new page? When the user clicks on the link, the audio just plays in the background?
(Don't want to use embed because it's just a 1 second audio for a word's pronunciation as a minor explanation of an uncommon word).
Actually the href attribute is redirecting you to the new page, you can use e.prevenDefault() in the link click event handler to stop this redirection and create a dynamic audio element with this href as source and play it.
This is what you need:
function playItHere(e, link) {
var audio = document.createElement("audio");
var src = document.createElement("source");
src.src = link.href;
audio.appendChild(src);
audio.play();
e.preventDefault();
}
Pronunciation of a word
In html5, you can actually use the <audio> tag to get that done!
<audio src="/music/myaudio.ogg" autoplay> Sorry, your browser does not support the <audio> element. </audio>
SOURCE: Wired
If you use a tag be careful with href .
Code snippet fixed .
First you will need to make convert ogg to the mp3 and than use it for multi source .
Small browser detector (chrome/opera/safari - mp3 and mozilla - ogg . )
E("PLAYER").addEventListener("error", function(e) {
console.log("error: " + e.target.error)
});
function PLAYER_BACKGROUND(what) {
var SOURCE_PATH = E(what).getAttribute("whattoplay")
if (isChrome == true)
{
SOURCE_PATH = SOURCE_PATH.replace(".ogg" , ".mp3")
}
else {
SOURCE_PATH = SOURCE_PATH.replace( ".mp3" , ".ogg" )
}
E("PLAYER").src = SOURCE_PATH
E("PLAYER").play()
}
<script>
var E = function(id){return document.getElementById(id)};
var isChrome = /Chrome/.test(navigator.userAgent) || /Safari/.test(navigator.userAgent);
</script>
<a id="audio_1" onclick="PLAYER_BACKGROUND(this.id)" whattoplay="https://maximumroulette.com/framework/res/audio/laser7.ogg" href="javascript:void(0)">Pronunciation of a word</a>
<audio style="display:none" id="PLAYER" autoplay controls>
<source src="#" type="audio/ogg">
<source src="#" type="audio/mpeg">

I use this to have a video player on browser
<video width="320" height="240" controls>
<source src="video.mp4" type="video/mp4">
</video>
Before clicking play, it display an image from the very beginning of the video, but in most of my video, first several seconds is black screen. Is it possible to make it get image at a specific time of the video, like "0:00:15", without creating thumbnail for the video?
I just want to add one more thing in this I guess you forgot to add preload="metadata" attribute in video tag like the below
<video preload="metadata" width="320" height="240" controls>
<source src="video.mp4#t=15" type="video/mp4">
</video>
and one more thing I want to add that this will not starts video after 15 seconds, this will only take an screenshot from video and make it as a first view of the video
Maybe this helps: (I have not tested it. Also you might be able to set the "poster" attribute of the video to the src of the image object. Just try it. =) )
<video width="320" height="240" controls id="video">
<source src="video.mp4" type="video/mp4">
</video>
$(document).ready(function() {
var time = 15;
var scale = 1;
var video_obj = null;
document.getElementById('video').addEventListener('loadedmetadata', function() {
this.currentTime = time;
video_obj = this;
}, false);
document.getElementById('video').addEventListener('loadeddata', function() {
var video = document.getElementById('video');
var canvas = document.createElement("canvas");
canvas.width = video.videoWidth * scale;
canvas.height = video.videoHeight * scale;
canvas.getContext('2d').drawImage(video, 0, 0, canvas.width, canvas.height);
var img = document.createElement("img");
img.src = canvas.toDataURL();
$('#thumbnail').append(img);
video_obj.currentTime = 0;
}, false);
});

Using the poster attribute is the easiest way to go. Getting a preview image of the video from a time other than the start is exactly what its designed for.
http://www.w3schools.com/tags/att_video_poster.asp
Trying to create a function to dynamically grab another segment of the video to use as the poster will undoubtedly create more latency and overhead for the client, negatively affecting the UX.
I did it this way:
It jumps to 0 if the currentTime is 15, but will go over the 15s mark when played
html:
<video id="video1" src="path/to/video#t=15" onplay="goToStart()" controls ></video>
javascript:
function goToStart(){
if (document.getElementById('video1').currentTime == 15){
document.getElementById('video1').currentTime = 0;
}
}
Add #t=15 to your video source, like below
<video width="320" height="240" controls>
<source src="video.mp4#t=15" type="video/mp4">
</video>
This will starts video after 15 seconds.
