Youtube video as div background not working with all videos - javascript

I am making use of the following solution for using a Youtube video as a website div background: https://stackoverflow.com/a/45377998
A JSFiddle example can be found in https://jsfiddle.net/350D/uq1vvavf/
The problem I am currently having is that not all videos will be shown. For example, the video in the JSFiddle works properly (https://www.youtube.com/watch?v=R3AKlscrjmQ). However, this video, for example will not work: https://www.youtube.com/watch?v=V5YOhcAof8I
I suspect this may have to do with the signal format (720p, 360p, etc.). I have made an attempt to debug the problem and found that a link for the non-working Youtube video is still returned within the streams array (just like the working video). I appreciate any hints to solving the problem.
HTML:
<video loop muted autoplay playsinline id="video"></video>
<pre></pre>
JS:
var vid = "R3AKlscrjmQ",
streams,
video_focused = true,
video_tag = $("#video"),
video_obj = video_tag.get(0);
$.getJSON("https://query.yahooapis.com/v1/public/yql", {
q: "select * from csv where url='https://www.youtube.com/get_video_info?video_id=" + vid + "'",
format: "json"
}, function(data) {
if (data.query.results && !data.query.results.row.length) {
streams = parse_youtube_meta(data.query.results.row.col0);
video_tag.attr({
src: streams['1080p'] || streams['720p'] || streams['360p']
});
document.addEventListener("visibilitychange", function() {
video_focused = !video_focused ? video_obj.play() : video_obj.pause();
});
} else {
$('pre').text('YQL request error...');
}
});
function parse_youtube_meta(rawdata) {
var data = parse_str(rawdata),
streams = (data.url_encoded_fmt_stream_map + ',' + data.adaptive_fmts).split(','),
result = {};
$.each(streams, function(n, s) {
var stream = parse_str(s),
itag = stream.itag * 1,
quality = false,
itag_map = {
18: '360p',
22: '720p',
37: '1080p',
38: '3072p',
82: '360p3d',
83: '480p3d',
84: '720p3d',
85: '1080p3d',
133: '240pna',
134: '360pna',
135: '480pna',
136: '720pna',
137: '1080pna',
264: '1440pna',
298: '720p60',
299: '1080p60na',
160: '144pna',
139: "48kbps",
140: "128kbps",
141: "256kbps"
};
//if (stream.type.indexOf('o/mp4') > 0) console.log(stream);
if (itag_map[itag]) result[itag_map[itag]] = stream.url;
});
return result;
};
function parse_str(str) {
return str.split('&').reduce(function(params, param) {
var paramSplit = param.split('=').map(function(value) {
return decodeURIComponent(value.replace('+', ' '));
});
params[paramSplit[0]] = paramSplit[1];
return params;
}, {});
}

As a workaround for now I used following solution https://codepen.io/henripeetsmann/pen/KpVVLq thanks to Henri Peetsmann. For me this works fine, even when changing the URL to one from Youtube. The only downside of using Youtube is that now you can't hide related video's when pausing. So I had to cover this part with something else.

Div with sprite-animation doesn't change properly during window.resize event

I am trying to imitate 3d-model rotation with a sprite sheet. I found a perfect example on Codepen, but it was not responsive.
What I tried to do is to write divs, containers and spritesize (in script) in vw, and then it is being checked in the window.resize event. It does work, but unfortunately not DURING window resize.
I put my snippet and three pictures in the post —
I opened website and everything is perfect - image
I started to change the size of my browser window and as you can see something is wrong - image
Now I tried to "rotate" the "model" with resized window and all is fine again - image

spriteslider.spritesize = clientWidth;

spriteslider.pixelsperincrement = 5;
spriteslider.multiplier = spriteslider.lastmultiplier = 0;
Draggable.create(spriteslider, {

The issue is because you're referencing t in the window.resize event handler, yet that variable has been defined in a different scope, and is not accessible from that location.
To fix this issue you can replace t in that function with the spriteslider variable, as that's what t is expected to contain. Try this:
var spriteslider = document.createElement('div');
var clientWidth = document.getElementById('spritetarget').clientWidth;
document.body.appendChild(spriteslider);
spriteslider.slider = document.getElementById('spriteslider');
spriteslider.sprite = document.getElementById('spritetarget');
spriteslider.spritesize = clientWidth;
spriteslider.spritecount = 20;
spriteslider.pixelsperincrement = 5;
spriteslider.multiplier = spriteslider.lastmultiplier = 0;
Draggable.create(spriteslider, {
type: 'x',
trigger: spriteslider.slider,
bounds: {
minX: 0,
maxX: 0,
minY: 0,
maxY: 0
},
edgeResistance: 0,
cursor: 'e-resize',
onDrag: function() {
if (this.isDragging) {
var t = this.target;
t.multiplier = Math.floor(this.x / t.pixelsperincrement) + t.lastmultiplier;
TweenLite.set(t.sprite, {
backgroundPosition: (-t.multiplier * t.spritesize) + "px 0"
});
}
},
onDragEnd: function() {
var t = this.target;
t.lastmultiplier = t.multiplier % t.spritecount;
}
});
window.addEventListener('resize', function(event) {
var clientWidth = document.getElementById('spritetarget').clientWidth;
spriteslider.spritesize = clientWidth;
TweenLite.set(spriteslider.sprite, {
backgroundPosition: (-spriteslider.multiplier * spriteslider.spritesize) + "px 0"
});
}, true);
body {
text-align: center;
font: normal 12px sans-serif;

make the video fill the screen width and and remove the frame

I have created this frame for playing the movie which resizes based on the user's screen size.
Now I want to be able to remove the frame and fill the whole width of the user screen using another function but each time I failed.
Now I'm using injectViewportSizes() function. I want a new function to do this:
remove the frame completely without affecting anything else.
stretch the width of the movie until it fills the whole width of the screen.
of course stretching the movie is much simpler for me than removing the frame ... each time I've tried to remove it the whole movie removes or a distortion occurs for the rest of the elements.
Here is the code:
const clipSource = `https://langfox.ir/movie/movieclip/My_name_is_Edward_Bloom.mp4`;
const content = document.querySelector('.content');
const box = document.getElementById("box");
let video = document.createElement('video');
content.appendChild(video);
video.id = 'clip';
let clip = document.getElementById("clip");
clip.currentTime = 0;
let source = document.createElement('source');
source.src = clipSource;
source.type = 'video/mp4';
video.appendChild(source);
video.load();
setTimeout(() => {
injectViewportSizes(); // or goFull();
clip.play();
}, 3000);
function goFull(){
// Remove the frame and make the video fill the while 'Width' of the screen
}
function injectViewportSizes(){
let screenWidth = screen.width;
let screenHeight = screen.height;
let vwPixels = screenWidth / 100;
let clipWidth = clip.videoWidth;
let clipHeight = clip.videoHeight;
screenWidth = screenWidth - (screenWidth * 0.10); // available space to put the clip inside
screenHeight = screenHeight - (screenHeight * 0.10);
let clipWidthNew;
let clipHeightNew;
if(clipWidth > clipHeight){
clipWidthNew = clipWidth;
let ratio = clipWidth / clipHeight;
while(screenWidth < clipWidthNew) {
clipWidthNew--;
}
clipHeightNew = clipWidthNew / ratio;
} else {
clipHeightNew = clipHeight;
let ratio = clipWidth / clipHeight;
while(screenHeight < clipHeightNew) {
clipHeightNew--;
}
clipWidthNew = clipHeightNew * ratio;
}
let viewPortClipWidth = clipWidthNew * (100 / document.body.clientWidth);
let viewPortClipHeight = clipHeightNew / vwPixels;
document.querySelector('.box .content').style.width = `${viewPortClipWidth}vw`;
document.querySelector('.box .content').style.height = `${viewPortClipHeight}vw`;
}

Note: it seems that this code snippet can't show the original frame correctly but it works in a raw HTML file locally.

Here is my progress so far (jsfiddle)
I had a project which I should embed multi videos. this is how I done it :
I used Bootstrap modal :
<div id="videoModal" class="modal">
<!-- Modal content -->
<div class="modal-content">
<span class="close">×</span>
<iframe id="videoIframe" class="full-width height-480"
src="https://www.youtube.com/watch?v=UM-ZPAF2Dpw" frameborder="0" allowfullscreen></iframe>
</div>
</div>
add this one only once, and in your button pass the youtube video ID like this :
<button onclick="showVideo('UM-ZPAF2Dpw')"><span class="glyphicon glyphicon-triangle-right"></span> Show Video 1</button>
you can have as many as button you like with different video ID
and in your script file you need to have this :
function showVideo(youtubeID){
var url = 'https://www.youtube.com/embed/' + youtubeID
document.getElementById('videoIframe').src = url;
// Get the modal
var modal = document.getElementById('videoModal');
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
modal.style.display = "block";
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
document.getElementById('videoIframe').src = '';
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
document.getElementById('videoIframe').src = '';
}
}
}

Generate Excel file thumbnail preview in Javascript

I have a project handling a library of excel files. To make it easilier for the users to visually scan them, I would like to generate preview thumbnail images of their content. Google drive does this (screenshot below) but I have no idea how.
Any ideas/suggestions on how this could be done (without using the drive API) ?
I guess this is what you need

This demo shows how to add live mini-previews to links on hover. Check out these links to SitePoint and A List Apart. Hover over them to see a small preview of what they point to.

Those previews were fetched as soon as this page loaded. This is great for having the previews ready ahead of time, but can eat up extra bandwidth. As an alternative, check out these links to Abduzeedo and Smashing Magazine. These previews aren't fetched until you hover over this paragraph.

Finally, check out these links to Daniel's blog, Joni's blog, and my blog. These previews are only fetched when needed. This saves the most bandwidth, but there will be a delay before the previews can be shown.

I just use a library to generate a PNG preview of the excel file and show it.
I use Free Spire.XLS for .NET because I'm in the .net world, but you can look at Wijmo Workbook Viewer for your Node.js needs.

Adding DIVs step-by-step...1, 2, 3, 4, 8, 16

I'm trying to create div boxes step by step and animate them for several times when a button is pressed. I have a running code, and everything is going well. It goes right to the endhost, then it goes left again to its original place. This is mainly what I do, and also the demo is found here: http://jsfiddle.net/LSegC/1/
Now what I want to do is to increase the number of whole animated DIVs one-by-one (as it is now) up to 3 Divs, but then have exponential increase on the total number of DIVs. So the total number of animated DIVs will be like 1, 2, 3, and then 4, 8, 16, etc.
Remember, my problem is not with the number being shown inside the DIV, it's actually that how many DIVS are being created! So I want for instance 8 DIVs, numbered from 1 to 8 animated. Hope it is now clear.
$(document).ready(function(){
$("button").click(function() {
var d = $(".t").fadeIn();
var speed = +$("#number1").val();
d.animate({left:'+=230px'}, speed);
d.animate({left:'+=230px'}, speed);
d.animate({top:'+=20px', backgroundColor: "#f09090", text:'12'}, speed/4, "swing", function() {
$('.span', this).fadeOut(100, function() {
$(this).text(function() {
return 'a' + $(this).text().replace('a', '');
}).fadeIn(100);
});
});
d.delay(1000).animate({left:'-=230px'}, speed);
d.animate({left:'-=230px'}, speed);
d.fadeOut().promise().done(function() {
d.last().after(function() {
var top = +$(this).css('top').replace('px', ''),
number = +$(this).data('number') + 1,
$clone = $(this).clone();
$clone.data('number', number).css('top', top + 20);
$clone.find('.span').text(number);
return $clone;
});
d.find('.span').text(function() {
return $(this).text().replace('a', '');
});
})
});
EDIT
Your code was too hard to manipulate as it was, I recreated the whole thing:

<div>Speed (mS):
<input value="500" id="speed" type="number" style="position: relative"></input>
<button>Apply!</button>

JS:
$(document).ready(function () {
var count = 0;
var items = 0;
var packetNumber = 0;
var speed = 0;
$("button").click(function () {
if (count < 4) {
items = items + 1;
count++;
} else {
items = items * 2;
}
speed = $("#speed").val();
createDivs(items);
animateDivs();
});
function createDivs(divs) {
packetNumber = 1;
var left = 60;
for (var i = 0; i < divs; i++) {
var div = $("<div class='t'></div>");
div.appendTo(".packets");
$("<font class='span'>" + packetNumber + "</font>").appendTo(div);
packetNumber++;
div.css("left",left+"px");
div.hide();
left += 20;
}
}
function animateDivs() {
$(".t").each(function () {
var packet = $(this);
packet.show();
packet.animate({
left: '+=230px'
}, speed);
packet.animate({
left: '+=230px'
}, speed);
packet.animate({
top: '+=20px',
backgroundColor: "#f09090",
text: '12'
}, speed / 4, "swing", function () {
$('.span').fadeOut(100, function () {
$(this).text(function () {
return 'a' + $(this).text().replace('a', '');
}).fadeIn(100);
});
});
packet.delay(1000).animate({left:'-=230px'}, speed);
packet.animate({left:'-=230px'}, speed);
}).promise().done(function(){
$(".packets").empty();});
}
});

FIDDLE: http://jsfiddle.net/54hqm/3/
It was tough for me to follow the code also, but I cut it back quite a bit, came up with a "one-way" "empiric" approach. FIDDLE
The speed can be adjusted by the change in the increment (inc), but there are a variety of methods that can be used.
Can you be more specific about what you mean by "exponential"? Do you mean an exponential speed increase across the div, or rather a speed increase until you get to 50%, then a decrement in speed.
JS
$("button").click(function() {
var speed = 1000;
var d = $('.mover');
d.show();
var inc = 1;
for (var i=0; i<290; i=i+inc)
{
d.animate({ left: i,
easing: 'linear'}, 1);
if (inc < 11)
{
inc = inc + 1;
} else {
inc = inc - 1;
}
}
});
