I have the following HTML code:
<video autoplay loop playsinline>
<source src="VIDEO-SRC-DESKTOP" type="VIDEO-TYPE" media="all and (min-width:1240px)">
<source src="VIDEO-SRC-MOBILE" type="VIDEO-TYPE">
</video>
In safari, if you open the respective URL directly, the correct source is shown. But the website is a single-page-application and if you navigate to a URL without page-reload and the video is rendered to the DOM after the initial pageload, it will always play the VIDEO-SRC-MOBILE.
For the SPA navigation I am using barbaJS. It probably also has to do with the fact that I have to actively call videoNode.play() after the page-transition as autoplay only seems to trigger on pageload as well.
Any ideas how to get safari to apply the media-query to the video-source? Or any other workaround known? I would like to avoid setting the src manually as the bug only applies to safari and it would also make the preloader-logic more complicated.

I have a simple HTML5 video embed that displays a blank (white) frame when loaded on iOS. On desktop browsers (including Safari) and Android the first frame of the video is displayed.
I understand that you can avoid this by setting an explicit poster image, but I'm hoping I can avoid having to set up a transcoding service to extract the first frame of the videos. I understand that Apple has probably chosen this route to limit the bandwidth use for mobile users, but in this instance it's just overkill to set up a transcoding service.
I've played around with the preload attribute, but neither setting it to
auto or metadata works. Is there any other way to display the first frame of the video without interaction from the user?
Here is a link to a pen where I am illustrating the problem.
https://s.codepen.io/webconsult/debug/oRmQva/vWMRwadNoNvr
And here is a screenshot of how the code is rendered on iOS simulator (same on real hardware) and in Chrome respectively.
You can use Media Fragments URI
Just Append #t=0.1 to the end of the video URL
Try following code. This is work for me
<video src="video/video.mp4#t=0.5" playsinline controls preload="metadata">
<source src="video/video.mp4#t=0.5" type="video/mp4">
</video>
HTML5 video player has been showing controls only in iOS 12.x.x even when the controls are set to false in video tag but all other browsers are working fine and don't show the controls.
The scenario is that whenever page loads we autoplay the video on banner but if battery saver feature is turned on then it will not autoplay the video shows the play button with initial thumbnail (only in iOS 12.x.x) while in other browsers it shows the initial thumbnail of the video without any play button.
My code looks like this:
<video id="header-video" autoplay="true" controls="false" playsinline="true" muted="true" loop="true">
// sources here
</video>
I am looking for the solution to hide this play icon (shown in attached image) but if that's not possible then is there any solution through which I can know that power saving mode is turned on and hide the video (because I have a background for backward compatibility).
I've given a look as well, and it seems as many CSS and JavaScript solutions out there don't work anymore, because since iOS 12 there is a new way of handling videos (https://www.reddit.com/r/apple/comments/8p4tpm/ios_12_to_include_custom_html_video_player/).
Now I came up with this idea, which as a purist I don't like, but it might do the trick: A video thumbnail (as image) overlayed over the video, that gets hidden, once the video is started.
You could have a standard thumbnail with title, or dynamically generate it (see http://usefulangle.com/post/46/javascript-get-video-thumbnail-image-jpeg-png as an idea).
Hope this helps!
I know this was asked over one year ago but I wanted to share the solution for others.
What I did was, I removed the autoplay attribute from the video-element and because I still wanted it to behave as with the attribute I added following js.
const video = document.getElementById('video-input');
video.play();
Setting autoplay to false and controls to false did work for me:
<video
src='xxxx'
muted
className='landing__empty-video'
loop
playsInline
autoPlay={false}
controls={false}
preload='auto'
type='video/mp4'
/>
Bear in mind this was React, in html case it would be "false".
After trying several solutions on the internet and without success, I eventually managed to hide the video interface elements in autoplay when the save mode is enabled.
document.getElementById("hello").setAttribute("autoplay", "autoplay");
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<video id="hello" playsinline preload muted loop>
<source src="https://www.w3schools.com/html/mov_bbb.mp4" type="video/mp4">
</video>
</body>
</html>

Below code is working fine in Mozilla & Chrome. But in Safari the video doesn't play.
<video id="v-control" width="100%" autoplay="autoplay" loop>
<source src="assets/img/web home page banner.mp4" type="video/mp4"
media="all and (max-width: 480px)">
<source src="video-small.webm" type="video/webm" media="all and
(max-width: 480px)">
<source src="assets/img/web home page banner.mp4" type="video/mp4">
<source src="video.webm" type="video/webm">
</video>
I have tried preload for the video tag and If I add controls I should click on Play button. I dont need any controls for the video so I have removed controls.
If the video is not working in Safari, but works in other browsers (Chrome, Firefox, Edge), you may be running into an issue relating to byte-range requests.
Byte-range requests are when a client asks a server for only a specific portion of the requested file. The primary purpose of this is to conserve bandwidth usage by only downloading small sections of the file as needed (a video in your case). If you inspect the Safari video request, you may notice a Range header set to bytes=0-1. This is Safari's way of testing if your HTTP servers accept byte ranges before requesting a larger chunk of data.
To fix your server config, take a look at Apple's recommendations. If you need a quick fix, you could move your videos to a different hosting server that has a proper config (and make sure to update all video source references).
Safari has started (in the last year) preventing videos with audio tracks from auto-playing by default. They never specifically publicised this as far as I'm aware, however I believe it was part of the following changes:
Safari 11 also gives users control over which websites are allowed to auto-play video and audio by opening Safari’s new “Websites” preferences pane
(Source)
The only real workarounds for this are to either remove the audio track from the video, or have it muted by default.
<video id="v-control" width="100%" autoplay="autoplay" loop muted>
If your server can detect the requester's browser, you can apply this to just Safari, leaving other browsers as they were before.
In my case i'm using angular with service-worker and Safari is not loading mp4 files.
The service worker breaks the Byte-range requests, because it is like man in the middle between safari and the server, in the process the SW change the http response code from 206 to 200, this way Safari do not download the mp4.
To solve this I bypass the service worker when I need to show an mp4 video, using angular 8 is its simple, just add ngsw-bypass=true as a query string in the mp4 url and in works. ( https://....video.mp4?ngsw-bypass=true )
The Other work around also includes, adding attribute playsInline to the video tag along with muted.
For Example, something like this :
<video id="v-control" width="100%" autoplay="autoplay" loop muted playsInline>
The playsInline allows the browser to play the video right where it is instead of the default starting point.
Keep in mind that the videos you are serving need to contain the metadata required for streaming.
In my case, I was serving dynamic videos encoded in the server using ffmpeg. Using the -movflags faststart in the ffmpeg command made the videos available to be played on Safari
Added an attribute "muted"
--- video muted autoplay---
in Chrome I have everything worked and Safari is also trying
I had a similar problem with videos not playing on Safari. The problem was my web server. I moved the video to another hosting server, loaded it from there and it worked.
e.g.
instead of:
<video src='/assets/myVideo.mp4' controls> </video>
do something like this:
<video src='https://anotherServer.com/assets/myVideo.mp4' controls> </video>
I am currently making a static site that makes use of a .mp4 video. I am using Middleman and hosting with Heroku (free plan). On my local server everything works wonderfully, but in the deployed Heroku version the video appears as a black box. In Safari and Firefox there is no container at all. All my other assets seem to be loading nicely. The video is 5.9 mb. Any idea what is going on here? Thank you in advance!!
<video class="vid-home" src="/videos/home.mp4" autoplay loop muted></video>
In theory, if you do not specify a 'poster' image to display before the video starts, the browser should display the first frame of the video:
http://www.w3schools.com/tags/att_video_poster.asp
In practice browsers seem to implement this inconsistently, and I have seen some mobile devices cases where certain videos display the first frame and others a black box, even for the same video types.
To avoid the issue you can specify your own image to be displayed using the mechanism mentioned in the link above - this should work consistently across browsers. The HTML will look something like:
<video class="vid-home" controls poster="yourImage.png" autoplay loop muted>
<source src="/videos/home.mp4" type="video/mp4">
Your browser does not support the video tag or format.
</video>
I have a video that I would like to embed in an O365 website using HTML5 embeding code. When I insert it, the video works fine but as soon as I click save the video area is just a black box and I can't play it. If I click to open it in another window it does play fine though for some reason.
The code I am using is the following:
<video width="320" height="240" controls>
<source src="my video.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>
Any idea why this would be happening?
While my questions remains valid as I don't know why it is happening, I found a work around for anyone having the same issue.
Rather than inserting the html embed code I inserted a media web part which was much easier and worked! I recommend this route!
