I am designing a website for people with visual impairments with focus on mobile usage. For now I have some simple buttons like "play", "stop" and voice over reads what I have put between <button></button> tags. However, I want to make it as precise as possible because older people might be using it as well and include something like "press this button to play recording" but then it becomes really long and the button just looks awful. Is there a way to include this information in a button without having to display this text on a website? I can't find the answer and it's the first time I am doing a project with focus on blind people.
<button>Play</button>
I would like to have a button like this, but so the voice over reads a hidden tag like "press this button to play recording". How can I do that?
You can use aria-describedby for this:
.help-text {
color: gray;
font-size: 0.75rem;
}
<button
id="play-button"
aria-describedby="play-button-explanation"
>
Play
</button>
<span
id="play-button-explanation"
class="help-text"
>
Press this button to play recording.
</span>
When I use VoiceOver on this button, I get:
Play, button. Press this button to play recording. You are currently on a button ...
This would work even if the element wasn't being displayed, but I think it's good to have that context for people who can read it, too.
If you are not intending to display the label text on the screen, you can use aria-label
<button
id="play-button"
aria-label="Press this button to play recording"
>
Play
</button>
Google Chrome is now shipping with a download button for videos that are just embedded videos (i.e. not MSE):
I'm having a hard time find any documentation for Chrome's implementation of the <video> tag. Does anyone know if there is a way - short of disabling "controls" and creating your own video player controls - of disabling this feature?
I realize that if this is showing, it's already easy to download the video, I just want to disable that functionality from appearing as part of the controls.
Thank you!
or you can simply add nodownload in controlsList
<video width="512" height="380" controls controlsList="nodownload">
<source data-src="mov_bbb.ogg" type="video/mp4">
</video>
You can inspect the controls of the native Chrome Video Player by activating the shadow DOM in Settings|Preferences -> Elements -> Show user agent shadow DOM
After that you can inspect the players buttons.
Now the problem is that the download button cannot be accessed via CSS for some reason.
video::-internal-media-controls-download-button {
display:none;
}
won't work.
Even selecting the preceding button and targeting its neighbor using + or ~ won't work.
The only way we found yet was nudging the button out of the viewable area by giving the control panel a greater width and making the enclosure overflow: hidden
video::-webkit-media-controls {
overflow: hidden !important
}
video::-webkit-media-controls-enclosure {
width: calc(100% + 32px);
margin-left: auto;
}
I hope google will fix this issue soon because most content providers won't be happy with this...
Demmongonis solution does work but be aware it can lead to unwanted results.
Android/Chrome sometimes, depends in the video I guess and other factors, adds buttons at the right of the download-button. i.e. the casting-button (there is no way to select it). It will make the download-button to remain visible and the last button to get hidden (casting-button)
Update
It is posible now to hide the download button using the controlsList attribute:
<video controlsList="nodownload" ... />
Yes, this is possible now, at least at the time of writing, you can use the controlsList attribute:
<video controls controlsList="nodownload">
<source data-src="movie.mp4">
</video>
It seems this was introduced in Chrome 58, and the documentation for it is found here: https://developers.google.com/web/updates/2017/03/chrome-58-media-updates#controlslist
Developers can now customize media controls such as the download, fullscreen and remoteplayback buttons.
Usage in HTML:
<video controls controlsList="nofullscreen nodownload noremote foobar"></video>
There is even an official sample page: https://googlechrome.github.io/samples/media/controlslist.html
One more control item I was trying to disable, additionally to 'download' - is 'picture-in-picture'.
Sadly there`s no property, for that purpose to be added in the controlsList. But there is an attribute - disablePictureInPicture you can add to the Element to disable pip.
Example disabling both download and picture-in-picture:
<video disablepictureinpicture controlslist="nodownload">...</video>
Details: https://wicg.github.io/picture-in-picture/#disable-pip
Hey I found a permanent solution that should work in every case!
For normal webdevelopment
<script type="text/javascript">
$("video").each(function(){jQuery(this).append('controlsList="nodownload"')});
</script>
HTML5 videos that has preload on false
$( document ).ready(function() {
$("video").each(function(){
$(this).attr('controlsList','nodownload');
$(this).load();
});
});
$ undevinded? --> Debug modus!
<script type="text/javascript">
jQuery("video").each(function(){jQuery(this).append('controlsList="nodownload"')});
</script>
HTML5 videos that has preload on false
jQuery( document ).ready(function() {
jQuery("video").each(function(){
jQuery(this).attr('controlsList','nodownload');
jQuery(this).load();
});
});
Let me know if it helped you out!
To keep it simple.. You need to add an attribute called controlslist (LOWERCASE, directly after controls) and you need to set its value to ="nodownload". Also, make sure your src file(type) and your attribute type's value match, unlike some of the above examples; my link is to a file named 'sunrise over water.mp4' on my Google Drive. How I do it looks like this:
<video src="https://drive.google.com/open?id=0B1CDu1eNPJqDVEQxMzZUV1dURjg" title="sunrise over water" width="420" height="300" controls controlslist="nodownload" type="video/mp4">
Video Not Supported By Your Browser...
</video>
OR
<video width="440" height="320" title="sunrise over water" controls controlslist="nodownload">
<source src="https://drive.google.com/open?id=0B1CDu1eNPJqDVEQxMzZUV1dURjg" type="video/mp4">
Video Could Not Be Played In Your Browser... Sorry.
</video>
In addition to above answers you have to add following code to disable context menu:
index.html: (globally)
<body oncontextmenu="return false;">
OR you can disable context menu for some element:
element.oncontextmenu = function (e) {
e.preventDefault();
};
Plain javascript to disable the "download" Button from a video in your page:
<script>
window.onload = function() {
video = document.querySelector('video');
if (video) {
video.setAttribute("controlsList", "nodownload");
}
};
</script>
If you want to, you can also is querySelectorAll and remove each video. In my example I just have only one video per page.
The above answer offers a good solution. However, when I was working on this in my project, there were two problems with it.
Download occurs (as if the download button had been pressed) when right margin area of the fullscreen button is touched on Android (mobile or tablet). Applying z-index didn't fix it.
Because of overflow:hidden, the download button is invisible but still exists to the right of the fullscreen button. That means when you press "tab" several times after clicking any control button or bar on PC, you can still reach the download button.
Additionally, be careful -- some small-width devices (e.g. mobile phones) are small enough to hide the seek bar. It would need many more pixels to hide the download button.
I hope Google provides the option to adjust this ASAP.
I using following JavaScript snippet which is working very well:
document.querySelectorAll("video[id^=media-player]").forEach((elem) => elem.controlsList.add("nodownload"));

I have a youtube video pop up that works well but I want to include a custom close button. I have done research but this has all come to nothing so I am hoping my stack buddies can help.
What I am estmiating from your question is you want a custom close button to close the DIV or iframe that your YouTube videos are in. I suggest jQuery for this:
$(function(){
$(".closeBtn").click(function(){
$($(this).data("target")).hide();
});
});
Then in the HTML:
<div class="video" id="v1">
<div class="closeBtn" data-target="#v1"></div>
<iframe></iframe>
</div>
JS Fiddle
What the data-target (data-target="#v1") does is target the ID of the div (<div class="video" id="v1">) then in jQuery, adding the animation effect .hide() , .fadeOut(500) to the ID.
i've a code which let start a youtubevideo after clicking on a image.
The Problem is, that Opera, Chrome ect. start the video behind the image before clicking.
Firefox works fine.
Heres my code:
<div onclick="thevid=document.getElementById('thevideo'); thevid.style.display='block'; this.style.display='none'">
<img style="cursor: pointer; margin-left: 89px;" src="./img/style/new/slider/XXXXXX.png" alt="" />
</div>
<div id="thevideo" style="display: none;">
<iframe width="604" height="266" src="//www.youtube.com/embed/XXXXXXXX?rel=0&autohide=2&showinfo=0&controls=0&modestbranding=0&wmode=transparent&showsearch=0&version=3&autoplay=1" frameborder="0" allowfullscreen></iframe>
</div>
Can you help me for a better code?
Additional is it possible to show the Image again after the video ends?
Thanks in advance
EDIT: push
What if you paste the iframe code to #thevideo when the user clicks the image?
I think you can use the .append() function in jQuery to do it.
The chrome/opera...browser issue is a known issue. There are browser settings that you can change that will make it so that it does not auto play the video, since you are really just putting a mask over the video. See this article: Stop youtube autoplay
EDIT:
To handle it with a programmatic approach:
change your autoplay value in the youtube url to "autoplay=0". Add an id value to your iframe, such as id="iframe". Then add the following line of code to the click function of your image: document.getElementById('iframe').src = document.getElementById('iframe').src.replace('autoplay=0','autoplay=1');

I used it and it works great!
I'm wondering if there's a quick and simple way to style the HTML5 audio element to display what I want. I was wondering if you could turn certain controls on and off, but that doesn't seem to be the case.
I do not want a progress/track bar, or to display the time left. I just want a simple play/pause toggle button, and a mute/unmute toggle button.
That's all! Any ideas?
Use this code it will serve your purpose.
<!DOCTYPE html>
<html>
<body>
<audio id="player" src="horse.ogg"></audio>
<div>
<button onclick="document.getElementById('player').play()">Play</button>
<button onclick="document.getElementById('player').pause()">Pause</button>
<button onclick="document.getElementById('player').muted=!document.getElementById('player').muted">Mute/ Unmute</button>
</div>
</body>
</html>
You could use the Media API and build your own set of controls with the functionality you want. I've written about this: Working with HTML5 multimedia components – Part 3: Custom controls - which shows a video example, but you can just as easily build an audio one.
