If you go to my site:
http://www.crookedfoothuntclub...
On mobile you will here the video play in the background. I have set the visibility to false on bigger screen-sizes and I was hoping that this would not only hide the video but prevent it from loading all together hence saving the end user bandwidth and load time. (Please keep this in mind on the primary objective I would like to accomplish).
As a stop gap I have tried to at least prevent the autoplay of the video by adding some custom JS.
The class name of the video on my home page is:
home-video
Here is the script I'm trying to use:
<script>
if($(window).width() >= 786){
var vid = document.getElementsByClassName("home-video");
vid.autoplay = false;
vid.load();
}
</script>
Currently the effect I'm going for is not happening and I need some help getting this to work.
If you know a better way to achieve the effect I'm asking about please consider me open to that approach in correcting the current situation.
Thank you for the help in advance.
Use Detectizr for your requirement and in if condition for mobile devices as vid.autoplay = false; and for desktop make it vid.autoplay = true;.
Thanks

Hello stackovercool community,
I'm trying to set a sound player on my site and display the title of the track in the footer. So far so good but I'd like to mute the music when clicking on the text title. I'd also liked to change the opacity of the text when paused.
I'm sorry my JS knowledge lacks, exactly, of knowledge. I tried this after various research but doesn't works.
function play(idPlayer) {
var player = document.querySelector('#' + idPlayer);
if (player.played) {
player.pause();
player.style.opacity = "0.5";
} else {
player.play();
player.style.opacity = "1";
}
}

Here's the working answer if anyone wants something similar.
Still doesn't works on my wordpress though, I think because of
var $j = jQuery.noConflict(); $j(document).ready(function()
I think the question is solved then.
I'm trying to make a kisok application to show some slides and play 2 videos from a menu using reveal.js. it is all working well and looks great apart from the video playback.
Im using a <video> tag inside the <section> as the data-background-video="something.mp4" didn't seem to restart on slide change either.
If i'm navigating out of the playing video slide and then returning to it, the video resumes where it left off and doesn't restart at the beginning as I require like even though autoplay is set to true.
I have tried to write something that does this with javascript using the api on Reveal.addEventListener after naming the <section> with data-state="something" and it works.. well kind of.. it works successfully for the first video only, well, then only for a while then it seems to break all video playback. the second video plays once then will not restart and i then can not control it via the console either.
here is the relevant html:
<!--*********************************************************Video 1 Page-->
<section id="rene_vid_page" data-state="video1_show" data-transition="fade-in fade-out" data-background="img/Backdrop.svg">
<h1 class="page_title">My page title</h1>
<video id="rene_vidplayer" data-autoplay data-src="Videos/full_edit_portrait.mp4" ></video>
<!--*********************************************************End Of Video 1 Page-->
<!--*********************************************************Video 2 Page-->
<section id="conc_vid_page" data-state="video2_show" data-transition="fade-in fade-out" data-background-color="#c8c8c8">
<h1 class="page_title">My page title</h1>
<video id="conc_vidplayer" data-autoplay data-src="Videos/2 Conclusions.mp4" ></video>
</section>
<!--*********************************************************End Of Video 2 Page-->
Here is the javascript i have cobbled together,
this also advances to the next slide when the video is finished and that bit works..
<script>
var video = document.getElementById("rene_vidplayer");
video.onended = function (e) {
console.log("video_ended slide advance");
Reveal.next();
};
Reveal.addEventListener('video1_show', function (e) {
// Called when "video1_show" slide is made visible
console.log('"rene video show has been called"');
video.currentTime = 0;
console.log('"videotime set to 0"');
video.play();
console.log('"video set to play"');
});
var video2 = document.getElementById("conc_vidplayer");
video2.onended = function (e) {
console.log("video2_ended slide advance");
Reveal.next();
};
Reveal.addEventListener('video2_show', function (e) {
// Called when "video2_show" slide is made visible
console.log('"video2_show has been called"');
video2.currentTime = 0;
console.log('"videotime set to 0"');
video2.play();
console.log('"video2 set to play"')
});
</script>
I can see in the console that the logs i have put in are working in the right places but the video stops behaving :( the second video will run from video2.play() in the console but only if the first one hasn't finished or the second one been played already.
You can tell that my js coding is not great at the moment and there are probably so many errors, and ultimately a much better way of doing this.
Any help or advice is greatly appreciated as it is desperately needed for a show next week!!
Ok, so i got this to work by adding a video.load() and video2.load() into the respective Reveal.addEventListener sections. Not sure if there are any problems associated with doing it this way or whether there is a better way?
However this is now working fine! :)
I'm making a HTML5 video player. I want it so that when the movie stops the play these executes
video.pause();
video.currentTime=0;
document.getElementById('message').innerHTML="Finished";
I tried this but it didn't work
function rewsi() {
var video = document.getElementsByTagName('video')[0];
if (video.currentTime==video.duration) {
video.pause();
video.currentTime=0;
document.getElementById('message').innerHTML="Finished";
}
}
Anyone got a solution for this problem?
Problem = My lack of knowledge in JavaScript
Looking at the following question and asnwer:
HTML5 <video> callbacks?
I would assign a callback to be executed when the video has actually ended like so:
var Media = document.getElementsByTagName('video')[0];
var Message = document.getElementById('message');
Media.bind('ended',function(){
Message.innerHTML = "The media file has completed";
});
You also stated that when the media 'stops' you want to pause the video, can you describe your motives for doing that ?
The next on the agenda is the video resetting as such, looks like you want to set the position of the media to the start if the media stops, you must first make sure that your determining that the video has not been paused, as you do not want to reset the position if the user has gone to make a cup of coffee.
If you only want to set the media position when the movie has actually ended then this would be pointless (unless you have a valid reason to do so), the reason it would be pointless is that when the user clicks play after it has ended, the default action html5 media player takes is to set the position to 0.
The above solution should work out exactly right for you.
i will recommend using Kaltura HTML5 Video Library to help you manage the media player.
First, you can check if the video has ended by simply putting a condition on video.ended. Then you can set the time with this.currentTime(0);
I've got a page with links to MP3s, when the link is clicked I use javascript to show a small Flash player (NiftyPlayer) under the link. When a different link is clicked, the old player is hidden and the new player is revealed.
The player auto-starts when the element is shown, and auto-stops when hidden - in Firefox.
In IE it will only auto-start and NOT auto-stop. This is what I would like to solve.
This is an example HTML with link and player
Misunderstood What You Said
<div id="player662431" class="playerhide"><embed src="http://www.example.com/shop/flash/player.swf?file=/mp3/Beat The Radar - Misunderstood What You Said.mp3&as=1" quality="high" bgcolor="#000000" width="161" height="13" name="niftyPlayer662431" align="" type="application/x-shockwave-flash" swLiveConnect="true" pluginspage="http://www.macromedia.com/go/getflashplayer"></embed>
Here is the javascript (I've got jQuery installed to let me hide all the open players on this page apart from the new one)
function toggle_visibility(id) {
$('.playerhide').hide();
var e = document.getElementById(id);
e.style.display = 'block';
}
I think what I need to do is start the player manually with javascript (rather than using the autostart as=1 function in the URL string)
There is some javascript that comes with NiftyPlayer to allow this EG
niftyplayer('niftyPlayer1').play()
there is also a stop method.
I need some help with javascript - how do I add this call to play into my toggle_visibility function (it has the same unique ID number added to the name of the player as the ID of the div that's being shown, but I don't know how to pull this ID number out of one thing and put it in another)
I also would like to be able to do
niftyplayer('niftyPlayer1').stop()
to stop the audio of the previously running player. Is it possible to store the current ID number somewhere and call it back when needed?
Thanks for the help, i'm a PHP programmer who needs some support with Javascript - I know what I want to achieve, just don't know the commands to do it!
Thanks
If you assigned each niftyplayer object a classname, f.x. ".players", then you could loop through each player, like this:
function toggle_visibility(id) {
$(".players").each(function(){
playerId = $(this).attr('id');
if(niftyplayer(playerId).getState() == 'playing') {
//Stop the currently playing player
niftyplayer(playerId).stop();
//Hide the div that was playing
$("#" + playerId).hide();
}
});
//Start the new player
niftyplayer(id).play();
$("#" + id).show();
}
So what this actually does, is it loops through all the players on the website. It checks if the status of each player is equal to "playing", if it is, then it stops it and hides the div tags. Then it starts the new player and shows that div tag.
I think this does it. Try it out.
I have a much better solution after I noticed a very nasty bug / 'feature' when using Internet Explorer in conjunction.
I had noticed that in IE the pages were taking a very long time to load when I had a lot of hidden Nifty Players, I looked closer using Fiddler and found that each instance of NiftyPlayer was preloading the MP3 in full, rather than loading on demand as with Firefox and Chrome etc.
This meant that a page with 100 items (each item having up to 4 MP3s) took several minutes to load at times with obvious data transfer implications.
My solution which is rather simpler (but maybe clunkier) than Indyber's is to just use
function toggle_visibility(id,mp3location) {
// hide all players
$(".playerarea").html('');
// show clicked player
$('#' + id).html('<embed src=\"http://www.xxx.com/shop/flash/player.swf?file=http://www.xxx.com/mp3/' + decodeURIComponent(mp3location) + '.mp3&as=1\" quality=high bgcolor=#000000 WMODE=transparent width=\"161\" height=\"13\" align=\"\" type=\"application/x-shockwave-flash\" swLiveConnect=\"true\" pluginspage=\"http://www.macromedia.com/go/getflashplayer\" class=\"playerNew\">');
}
which works fine with IE, and also solves the problem of not being able to stop the players from playing in IE
Is there a way to detect end of Flash movie (OOTB, without using some sort of flash callback).
Alternatively, is there a way to know the length of the movie?
Update:
IsPlaying() looked promising (periodically checking it), but as it turns out, nobody is creating straight forward swfs any more; now, the content is embedded in main layer and while the content plays, the main movie is stopped and IsPlaying is always false...
var movie = window.document.movie
if(movie.TCurrentFrame("/") == movie.TotalFrames())
alert("Movie Finished");
or you could have:
if (!movie.IsPlaying())
alert("Movie Stopped");
but thats not really what you're after.
import fl.video.VideoEvent.COMPLETE
video.addEventListener(VideoEvent.COMPLETE, alertHTML);
function alertHTML(e:VideoEvent):void{
ExternalInterface.call("alert(\"Video has stopped\");");
}
Give that a shot. You can replace the alert(\"Video has stopped\"); with your client-side javascript function.
You can chceck for movie length with ffmpeg -i movie.flv 2>&1, but i doesnt' tell you:
how long it takes to load the video and start playing
whether the user has hit the "pause" button.
Right now, the only way is to attach some javascript handlers to Flash events as other posts suggest.
