Countdown to the end of the HTML5 video - javascript

Can I make a countdown to the end of the HTML5 video?
<video id="video" width="400" height="225" preload="auto">
<source src="video.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' />
</video>
<div id="countdown">Video ends after <span>XX</span> seconds.</div>
I understand that a have to wait for the video load, and then if the video is loaded, need to know the length and run video and coundown.

Listen to the timeupdate event fired by the video object and update the time remaining.
Something like this should work:
var video = document.getElementById('video');
video.addEventListener('timeupdate', updateCountdown);
function updateCountdown() {
var timeSpan = document.querySelector('#countdown span');
timeSpan.innerText = video.duration - video.currentTime;
}

This should do the trick for you
countdown = video.duration - video.currentTime

Play only first 30 Seconds of the video HTML5

I m trying to make my video play only the first 30 secs of the video and return to the starting time going as loop irrespective of video length.
Here's my code so far.
HTML
<video width="100%" height="192px" id="player" controls loop >
<source src="images/videos/<?= $v_video; ?>" type="video/mp4">
<source src="images/videos/<?= $v_video; ?>" type="video/ogg">
</video>
JS
<script>
var playTimeout;
$("#player").on("play", function(e) {
playTimeout = setTimeout(function() {
$("player").pause();
$("player").setCurrentTime(0); // Restarts video
}, 30000); // 30 seconds in ms
});
$("#player").on("pause", function(e) {
clearTimeout(playTimeout);
});
</script>
However, it stills keeps on playing after 30sec.
Any help is appreciated.
$("player").pause();
$("player").setCurrentTime(0); // Restarts video
needs to be
$("#player").get(0).pause();
$("#player").get(0).currentTime = 0; // Restarts video
Also, I would use the timeupdate event so that the video doesn't reset while it is still loading (in your example, with a slow connection, if they spend 10 seconds buffering before playback, it would reset after only 20 seconds of playing).
See example (set to 3 seconds instead of 30 for easier demo):
var playTimeout;
$("#player").on("timeupdate", function(e) {
playTimeout = setTimeout(function() {
$("#player").get(0).pause();
$("#player").get(0).currentTime = 0; // Restarts video
}, 3000); // 3 seconds in ms
});
$("#player").on("pause", function(e) {
clearTimeout(playTimeout);
});

<video id="player" controls="true" height="200" width="300">
<source type="video/ogg" src="http://media.w3.org/2010/05/bunny/movie.ogv">

HTML5 Video - pause for a few seconds then continue playback

I have a HTML5 video element in my page and what I'd like to happen is when it reaches the 3 second mark, it needs to pause for 2 seconds and then continue playback.
The video length is about 8 seconds.
<video id="video" playsinline autoplay muted loop>
<source src="video.mp4" type="video/mp4"/>
<source src="video.webm" type="video/webm"/>
</video>
This does it
const video = document.getElementById('myVideo');
function playVid() {
video.play();
window.setTimeout(pauseVid, 3000);
}
function play() {
video.play();
}
function pauseVid() {
video.pause();
window.setTimeout(play, 5000);
}
setTimeout() .currentTime & timeupdate
Go to the link above to understand why setTimeout() ain't so great.
.currentTime Property
This property is used by <audio> and <video> tags to get/set playback time in seconds. In the following demo it is used to get the time:
var t = this.currentTime;
timeupdate Event
This event fires 4 times a second while an <audio> or <video> tag is playing. In the demo both a <video> and <audio> tag are registered to to the timeupdate event:
video.addEventListener("timeupdate", tick);
timer.addEventListener("timeupdate", tock);
Setup
[controls] Attribute
Added so the time can be reviewed as the demo runs, it's optional and recommended that it not be used in production.
<audio> Tag
An <audio> tag has been added as a timer, The attributes [muted] and [autoplay] are required:
<audio id='timer' src='https://od.lk/s/NzlfOTEwMzM5OV8/righteous.mp3' muted controls autoplay></audio>
Both tags will start playing and are listening to the timeupdate event and will call a function at a predetermined time:
function tick(e) {
var t = this.currentTime;
if (t >= 3) {
this.pause();
video.removeEventListener("timeupdate", tick);
}
}
function tock(e) {
var t = this.currentTime;
if (t >= 5) {
video.play();
timer.removeEventListener("timeupdate", tock);
}
}
Basically when the <video> and <audio> tags are triggered every 250ms, they are calling those functions:
<video> calls function tick()
if the playback time is 3 or more seconds it pauses.
to avoid constant triggering every 250ms, the eventListener is removed.
<audio> calls function tock()
if the playback time is 5 or more seconds it will play the <video>.
for the same reason as the <video>, the eventListener is removed.
Demo
var video = document.getElementById('video');
var timer = document.getElementById('timer');
video.addEventListener("timeupdate", tick);
timer.addEventListener("timeupdate", tock);
function tick(e) {
var t = this.currentTime;
if (t >= 3) {
this.pause();
video.removeEventListener("timeupdate", tick);
}
}
function tock(e) {
var t = this.currentTime;
if (t >= 5) {
video.play();
timer.removeEventListener("timeupdate", tock);
}
}
<video id="video" playsinline muted loop controls autoplay width='300'>
<source src="https://html5demos.com/assets/dizzy.mp4" type="video/mp4"/>
</video>
<audio id='timer' src='https://od.lk/s/NzlfOTEwMzM5OV8/righteous.mp3' muted controls autoplay></audio>

JavaScript addEventListener pause and play video

I have a video in my html. I would like the video to pause at 5 seconds after playing so I used addEventListener. I also have 2 buttons that call either restart() or jump().
When I play my video, an EventListener is called on my video. It pauses at 5 seconds, but I can't get it to play after 5 seconds (I've tried removing the listener but then the video no longer pauses). When I call jump(), it'll take me to 10 seconds but continue to pause when I try to play it. When I call reset(), the video will play up to 5 seconds again, which makes sense since I have a Listener on it. How do I get it to play after 10 seconds for when I call jump()? At first I thought I would have to remove my Listener but I believe I'll need that still because I would like the video to pause at 15 seconds. Or maybe I need to call removeEventListener somewhere else?
js
var video = document.getElementById("myvid");
video.addEventListener("timeupdate", function(){
if(this.currentTime >= 5) {
this.pause();
}
});
function restart(){
video.currentTime = 0;
}
function jump(){
video.currentTime = 10;
if (video.currentTime >=15){
video.pause
}
}
html
<video id="myvid" width="320" height="240" controls>
<source src="video.mp4" type="video/mp4">
</video>
<button onclick="restart()">restart</button>
<button onclick="jump()">jump</button>
You must keep the pause time in a variable. Then you can use it in the jump function:
var video = document.getElementById( 'myvid' ),
pausedtime = 0;
video.addEventListener( 'timeupdate', function() {
if ( this.currentTime >= pausedtime + 5 ) {
this.pause();
pausedtime = this.currentTime
}
});
function restart(){
video.currentTime = 0;
pausedtime = 0;
video.play()
}
function jump(){
pausedtime += 5;
video.currentTime = pausedtime;
video.play()
}
<video id="myvid" width="320" height="240" controls>
<source src="http://iandevlin.com/html5/media-player/parrots.mp4.mp4" type="video/mp4">
<source src="http://iandevlin.com/html5/media-player/parrots.webm" type="video/webm">
</video>
<br>
<button type="button" onclick="restart()">Restart</button>
<button type="button" onclick="jump()">Jump</button>

Autoplay sound mp3 each one minute

how can using php play a sound each 1 or 2 min
when a user enter in the page the first sound play
after 1 min another sound will be played and the first will be stopped of
course all that will be auto play
html5 code:
<audio controls autoplay>
<source src="horse.mp3" type="audio/mpeg">
</audio>
Simply you can merge both sound with your timing and implemented just like this:
<audio controls="controls" onloadeddata="audioSoundFunction()">
<source src="horse.mp3" type="audio/mp3" />
</audio>
Javascript:
function audioSoundFunction() {
var audioSound = this;
setTimeout(function() {
audioSound.play();
}, 10000)
}
<audio id="selecterForAudio" controls autoplay>
<source src="horse.mp3" type="audio/mpeg">
</audio>
javascript/jquery
var myVar = setInterval(myTimer, 60000);
var audio = $("#selecterForAudio")[0];
var counter = 0;
var musicfiles = ["horse.mp3", "lard.mp3"];
function myTimer(){
//stopping the audio
audio.stop();
//setting new source of array of sources
$('#selecterForAudio').find('source').attr('src',musicfiles[counter]);
counter+1;
if(counter>COUNT(musicfiles)){
counter=0;
}
//play sound
audio.play();
}
something like this should fit your needs - it might need a little tweeking though

Why video defaultPlaybackRate doesn't work in Chrome?

I saw some examples of defaultPlaybackRate and they say it work on Chrome. So I use their example codes and run on Chrome, it doesn't change the speed to 3.0x when I click the button. Anyone can tell me why?
Here my javascript code,
$(document).ready(function(){
var video = document.getElementById('video');
$("#speed").click(function() { // button function for 3x fast speed
video.defaultPlaybackRate=3.0;
});
});
The HTML codes,
<button id="speed" type="button">3.0x</button>
and
<video id="video" width="930" height="500" controls>
<source src="caption.mp4" type="video/mp4">
<source src="caption.ogg" type="video/ogg" >
<source src="caption.webm" type="video/webm" >
</video>
Because once you change the defaultPlaybackRate you have to load the video again using video.load(); (or set it before the video has loaded). If you want to change the rate while the video plays, use playbackRate instead.
var video = document.getElementById('video');
$("#speed").click(function () { // button function for 3x fast speed
video.defaultPlaybackRate = 3.0;
video.load();
});
or
var video = document.getElementById('video');
$("#speed").click(function () { // button function for 3x fast speed
video.playbackRate = 3.0;
});
