I want to overlay a video with some text. The html/css works fine in Safari and Firefox - but in Chrome the text disappears on scrolling. Here is a quick video showing the problem: https://imgur.com/2iShiaL
The HTML/CSS is quite straight forward:
<figure>
<video preload autoplay loop muted playsinline src="https://zachholman.com/video/utc-one.mp4" poster="https://zachholman.com/images/talks/utc/poster-one.jpg">Your browser does not support the video tag.</video>
<h1 style="left:8vw; top:6vw; font-size: 5vw; color:blue;">
<div>What is</div>
<div>Time?</div>
</h1>
</figure>
and
* {
margin: 0;
padding: 0;
}
figure {
position: relative;
}
figure video {
width: 100%;
display: block;
}
figure h1 {
position: absolute;
}

Is this a well know bug in Chrome? Is there a work around?
This was fixed in a recent build. Updating Google Chrome fixed it. So simple.

I have a basic example of using the track element to load captions. In Firefox, the captions render sometimes, but not other times. Things that I have checked:
CSS positioning of video element (still see the issue with no positioning change)
Opening a private window (sometimes makes them show)
Disabling cache
CORS headers of mp4/vtt server (they are set to Access-Control-Allow-Origin: *) and the video tag has crossorigin="anonymous"
Changing autoplay and muted attributes
Reproduced intermittently in Firefox versions 97.0 and 98.0b4. I haven't noticed this issue in other browsers.
Edit: I added some CSS to this snippet that makes the issue repro for me now. So it's pointing to CSS, but weirdly, once I reproduce it, the captions continue to remain hidden even when I remove all styles.
.modal {
display: flex;
flex-direction: column;
}
.video-wrap {
flex-grow: 1;
height: 480px;
position: relative;
}
video {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
width: 100%;
height: 100%;
background: black;
}
::cue {
color: pink;
}
<div class="modal">
<h1>Video w/ VTT</h1>
<div class="video-wrap">
<video controls muted crossorigin="anonymous">
<source
src="https://cuttle-learning.netlify.app/onboarding-sketch/videos/onboarding2.mp4?cachebreak=001"
type="video/mp4"
/>
<track
label="English"
kind="captions"
srclang="en"
src="https://cuttle-learning.netlify.app/onboarding-sketch/videos/onboarding2.vtt?cachebreak=001"
default=""

</video>

Sounds like it's this bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1733232
That's currently the most minimal example I have which consistently
fails. Some (basic) examples fail after a couple of reloads. I assume
that's because of caching and layout complexity.
I am currently using a video as a background for my website, it works perfectly in my chrome browser, but when I use safari- it shows the video controls for the video in the background. Is there any way to hide these controls or maybe just a better way to have the video in the background?
here's my code for the background video
HTML
<video id = 'home-bg' src = {require('../assets/leojaden-video-bg-2.mp4')} muted loop autoPlay playsinline/>
CSS
*{
box-sizing: border-box;
margin: 0;
padding: 0;
}
#home-bg{
position: absolute;
filter: brightness(80%);
top: 0;
left: 0;
height: 100vh;
width: 100vw;
object-fit: cover;
z-index: -1;
}
video::-webkit-media-controls {
display: none;
}
I am using reactjs for this website, so a react friendly solution would be helpful! :)
You can hide the controls by not adding the controls attribute to the video element.
<video autoplay playsinline></video>
My website shows a video using video tag which worked perfectly until not long ago.
The video is working but when pressing on full screen, the video is playing but the screen is black while the sound is still playing. The issue occurs only on iPhones with iOS 15 (using Safari and Chrome also).
Things I've tried:
I've tried playing the video directly with a URL to the actual file(to check its not codec issue) and it worked properly.
My video tag has 'position: absolute;' on it and I tried removing it(even though it breaks my layout) and that didn't work either.
Tried pausing the video immediately and playing it after the video loads.
Tried applying a background: white; or any non-transparent color to the video tag.
Tried removing auto play.
Tried to disable 'GPU process: Media' on safari settings just to check if that affects anything
and it didnt.
This is the html:
<video data-test-id="long-video" #longVideo muted controls playsinline [class.d-none]="!isShortVideoHidden"
*ngIf="isPageLoaded" src="https://cdn1.someurl.com/videos/commercial_1.mp4"
type="video/mp4">
</video>
and the css(with the parent):
#media only screen and(min-width:992px) {
.fixed-video {
position: fixed;
z-index: 10000;
margin: auto;
width: 100vw;
height: 100vh;
left: 0;
top: 0;
bottom: 0;
right: 0;
background: rgba(0, 0, 0, 0.5);
transition: 0.4s;
video {
width: 80%;
left: 0;
right: 0;
top: 0;
bottom: 0;
margin: auto;
}
}
}
Please tell me if you have struggled with this and know how to solve it.
Thank you :)
I have been building an app recently and have a loading animation playing at the start (just a mp4 video - for aesthetic purposes). It works great everywhere apart from on Iphone.
The issue is that there is a grey line around some of the video - not the same on every side. If i try to screenshot the page the lines are no longer visible.
I am using an iphone 7 plus and ios safari. To see for yourself see - https:pathfinder-new.herokuapp.com
The goal is for it to be seamless with the white background - example can be seen on desktop at above address.
Cheers,
Tim
I’ve been struggling for a few hours and found this as the only way to remove it (tested on Safari, Chrome and Firefox on iOS):
video {
-webkit-mask-image: -webkit-radial-gradient(white, black);
-webkit-backface-visibility: hidden;
-moz-backface-visibility: hidden;
}
Took inspiration from this gist
I tried that on iOS 12 installed iPad WiFi 2017 on Safari and things were all good. Do you have any chance to video that glitch with another recording device?
Edit: General appearance cleaner -webkit-appearance: none may do the trick.
I had to go with the approach of a wrapper div and a position absolute one, something like:
HTML
<div class="wrapper">
<video loop muted autoplay playsinline>
<source src="./video.mp4" type="video/mp4">
<source src="./video.webm" type="video/webm">
<source src="./video.ogv" type="video/ogg">
</video>
<div class="video-ios-border-fix"></div>
</div>
CSS
.wrapper {
display: block;
position: relative;
font-size: 0;
}
.video-ios-border-fix {
position: absolute;
z-index: 1;
box-sizing: initial;
left: -2px;
top: -2px;
right: -2px;
bottom: -2px;
border: 4px solid #fff;
}
video {
width: 100%;
}
What I want is for example:
<video> = z-index: -1;
<div id="post"> = z-index: 0;
I've tried this to a certain degree... but it would be good to know if anyone has some concrete information on it. I'm new to H5 Video, and I know with Flash it is possible, but not for mobile devices (which I don't care about atm, can have some crappy fallback)
Thanks for any info in advance.
You can stack elements on top of html5 video using z-index, exactly as you described. You can see my demo with this jsfiddle, http://jsfiddle.net/cJJwj/3/
And here's the code that I use in that fiddle:
HTML
<video width="200" height="200"
controls="controls"
src="http://upload.wikimedia.org/wikipedia/commons/4/43/Eisbach_surfen_v1.ogv">
</video>
<p>paragraph</p>
CSS
video {
position: relative;
z-index: 0;
}
p {
position: absolute;
top: 50px;
left: 50px;
color: red;
font-size: 2em;
border: medium solid yellow;
z-index: 1;
}
I should mention, however, that I tried using z-index: -1; for the video, and the video controls wouldn't work (in Firefox 5 beta and Chrome), but when I used z-index: 0 instead, the controls worked fine. I don't know why that is yet.
I haven’t worked with HTML5 video much either, but I know that the Vimeo HTML5 player seems to do exactly what you’re asking. They use <div> and even <canvas> above the video to render the playback controls, title, and other buttons.
