flickity.js play/pause video based on current cell

I am using Flickity to create a slider of images and videos. When changing slides, I want to play the video on the current slide (which has a class of .is-selected), and then pause again once I move to the next slide.
The code below manages to find any videos within the slider, but plays them on any slide change, rather than specifically for the slide they are within. Any help would be much appreciated.
// Init Flickity
var $carousel = $('.carousel');
$carousel.flickity();
// On slide change
$carousel.on('change.flickity', function() {
// Find videos
var currentSlide = $(this).find('.is-selected');
var video = $(this).find('video');
// Play videos
video[0].play();
});

What you want to do is pause all videos on every slide change and only play the one on the selected slide. I did something similar (without jQuery):
var carousel = document.querySelector(".carousel");
var flkty = new Flickity(carousel, {
// ..
});
flkty.on("change", function() {
console.log("Flickity active slide: " + flkty.selectedIndex);
flkty.cells.forEach(function(cell, i) {
if (cell.element == flkty.selectedElement) {
// play video if active slide contains one
// use <video playsinline ..> in your html to assure it works on ios devices
var video = cell.element.querySelector("video");
if (video) {
console.log("playing video " + i);
video.play();
}
return;
}
// pause all other videos
var video = cell.element.querySelector("video");
if (video) {
console.log("pausing video " + i);
video.pause();
}
});
});
As I stated in the comment, you might wanna use the "playsinline" attribute for your videos, otherwise you'll run into problems on iOS.
Also: using the "settle" event instead of "change" allows you to start playing once the active slide settled at its end position.

Button to mute/unmute video bg on divi theme

I'm making a website for a client using the divi theme. The site has a background video with sound. The customer wants in the video a button to turn the sound on and off.
With the following code I was able to mute but I can not make a button to turn on and off.
Can someone help me?
jQuery (document) .ready (function () {
jQuery (". et_pb_section_video_bg video"). prop ('muted', true);
});

Try with volume level!
Edit
And here are the functions for some volume down/up buttons.
$(document).ready(function(){
// Video element
var myVideo = $(".et_pb_section_video_bg video")[0];
// On load state (muted)
myVideo.volume = 0;
$("#sound_up").on("click",function(){
var actual_volume = myVideo.volume;
if(actual_volume<1){
myVideo.volume += 0.2;
}
});
$("#sound_down").on("click",function(){
var actual_volume = myVideo.volume;
if(actual_volume>0){
myVideo.volume -= 0.2;
}
});
});
Assuming the et_pb_section_video_bg video class is on the video element...

External Play Pause Button Swap SVG & Text on State Change

I have an external button below the playback window used to toggle play and pause, which has a CSS SVG background image with the following code, works great:
<a onclick="jwplayer().play();" class="jwp-btn jwp-btn-icon-pl">Play</a>
What I want to do is a state change, so that if the "> Play" is displayed on the button, and the user clicks the button to play, that the SVG, and text swaps to "|| Pause" (using a different SVG and text). And then reverses back if the button is clicked again.
I suspect that this will use JavaScript (which I'm OK with, jQuery is OK too), and jwplayer().on('play') and jwplayer().on('pause') event triggers. The SVG icon does not have to be in CSS.
But I'm at a loss as to how to achieve this.
Here's the player code (using a playlist as well):
<script>
var playerInstance = jwplayer("containerpreview");
playerInstance.setup({
//file: "//content.jwplatform.com/videos/12345.mp4",
//image: "//content.jwplatform.com/thumbs23456.jpg",
//playlist: "//content.jwplatform.com/feeds/123.rss",
playlist: "//cdn.jwplayer.com/v2/playlists/222?format=mrss",
displaytitle: false,
width: "100%",
aspectratio: "16:9"
});
var list = document.getElementById("list");
var html = list.innerHTML;
playerInstance.on('ready',function(){
var playlist = playerInstance.getPlaylist();
for (var index=0;index<playlist.length;index++){
var playindex = index +1;
html += "<li><span class='dropt' title='"+playlist[index].title+"'><a href='javascript:playThis("+index+")'><img height='75' width='120' src='" + playlist[index].image + "'</img></br>"+playlist[index].title+"</a></br><span style='width:500px;'</span></span></li>"
list.innerHTML = html;
}
});
function playThis(index) {
playerInstance.playlistItem(index);
}
</script>

You didn't provide any HTML, Js code about your file (just a single a tag is not enough), but this will give you an idea about how you can do this:
js/jQuery:
jwplayer("containerpreview").on('play', function(){
$('.jwp-btn').empty().html("Your (Pause)SVG Element");
});
jwplayer("containerpreview").on('pause', function(){
$('.jwp-btn').empty().html("Your (Play)SVG Element");
});

building a Jquery Tool slider like yahoo.com slider details

Hi im trying to achieve a "news slider" like the one you can see in yahoo.com... I almost have the 100% of the code.. (if you want to compare them here is my code http://jsfiddle.net/PcAwU/1/)
what is missing in my code , (forget about design) is that , In my slider you have to clic on each item, i tried to replace Onclick for Hover on the javascript, it worked, but the fisrt image on the gallery stop working, so when you just open the slider, you see a missing image.
Other point.. also very important, in yahoo.com after "x seconds" the slider goes to the next item, and so on ... all the Thumnails are gruped 4 by for 4, (in mine 5 by 5, thats ok) ... after pass all the 4 items, it go to the next bloc..
HOW CAN I ACHIEVE THAT!!. I really looked into the API, everything, really im lost, i hope someone can help me. cause im really lost in here.
Thanks
Here is the script
$(function() {
var root = $(".scrollable").scrollable({circular: false}).autoscroll({ autoplay: true });
$(".items img").click(function() {
// see if same thumb is being clicked
if ($(this).hasClass("active")) { return; }
// calclulate large image's URL based on the thumbnail URL (flickr specific)
var url = $(this).attr("src").replace("_t", "");
// get handle to element that wraps the image and make it semi-transparent
var wrap = $("#image_wrap").fadeTo("medium", 0.5);
// the large image from www.flickr.com
var img = new Image();
// call this function after it's loaded
img.onload = function() {
// make wrapper fully visible
wrap.fadeTo("fast", 1);
// change the image
wrap.find("img").attr("src", url);
};
// begin loading the image from www.flickr.com
img.src = url;
// activate item
$(".items img").removeClass("active");
$(this).addClass("active");
// when page loads simulate a "click" on the first image
}).filter(":first").click();
// provide scrollable API for the action buttons
window.api = root.data("scrollable");
});
function toggle(el){
if(el.className!="play")
{
el.className="play";
el.src='images/play.png';
api.pause();
}
else if(el.className=="play")
{
el.className="pause";
el.src='images/pause.png';
api.play();
}
return false;
}

To fix the hover problem you need to make some quick changes: Change the click to a on(..) similar to just hover(..) just the new standard.
$(".items img").on("hover",function() {
....
Then You need to update the bottom click event to mouse over to simulate a hover effect. Trigger is a comman function to use to trigger some event.
}).filter(":first").trigger("mouseover");
jSFiddle: http://jsfiddle.net/PcAwU/2/
Now to have a play feature, you need a counter/ and a set interval like so:
var count = 1;
setInterval(function(){
count++; // add to the counter
if($(".items img").eq(count).length != 0){ // eq(.. select by index [0],[1]..
$(".items img").eq(count).trigger("mouseover");
} else count = 0; //reset counter
},1000);
This will go show new images every 1 second (1000 = 1sec), you can change this and manipulate it to your liking.
jSFiddle: http://jsfiddle.net/PcAwU/3/
If you want to hover the active image, you need to do so with the css() or the addClass() functions. But You have done this already, All we have to do is a simple css change:
.scrollable .active {
....
border-bottom:3px solid skyblue;
Here is the new update jSFilde: http://jsfiddle.net/PcAwU/4/

Dynamic sounds not playing after two plays

I have a little html5 application where you can play a sound by clicking a button.
I have a function that adds an <audio> tag to a <div> with an id "playing." The sound removes itself when it is done.
function sound(track){
$("#playing").append("<audio src=\"" + track + "\" autoplay onended=\"$(this).remove()\"></audio>");
}
For the button I have:
<button onclick="sound('sounds/tada.mp3')">Tada</button>
When I click the button, an <audio> briefly appears in the element inspector and disappears when it is finished, just the way I want it, but after triggering it two times, it just stops working in Chrome, at least. There are no errors in the console either.
What is going on?

Get rid of the onclick/onend in your HTML and reference the button in your js:
HTML
<button id='tada' sound_url='sounds/tada.mp3'>Tada</button>
And the JS
var sound = function(track){
$("#playing").append("<audio id='played_audio' src='\" + track + \"' autoplay='true'></audio>");
}
$('#tada').on('click', function () {
var sound_url = $(this).attr('sound_url');
sound(sound_url);
});
$('#playing').on('end', 'played_audio', function() {
$(this).remove();
});

Okay, lets see..
var audioURL = "http://soundbible.com/mp3/Canadian Geese-SoundBible.com-56609871.mp3";
var audioEl = null;
function removeAudio() {
if (audioEl && audioEl.parentNode)
audioEl.parentNode.removeChild(audioEl);
}
function sound() {
removeAudio();
audioEl = document.createElement("audio");
audioEl.src = audioURL;
audioEl.controls = true;
audioEl.addEventListener("ended", removeAudio); // <-- Note it's ended, not end!
document.getElementById("playing").appendChild(audioEl);
audioEl.play();
}
document.getElementById("tada").addEventListener("click", sound);
<div id="playing">
</div>
<button id="tada">Tada</button>
I'm not seeing any problems with this script.
Decide audioURL, set audioEl to null as it will be used later
When the element with ID "tada" is clicked, run our sound function.
Remove the audio.
Create the audio element.
When the audio is finished, remove the audio.
Append the audio to the element with ID "playing".
Play the audio.
One thing to note is that I use the ended event, not the end event.
