I am having a bit of trouble implementing a video into my site.
I use this block of code:
<video id="video-background" poster="/video/video-poster.jpg" autoplay loop muted playsinline>
<source src="/video/video.webm" type="video/webm">
<source src="/video/video.mp4" type="video/mp4">
<source src="/video/video.ogg" type="video/ogv">
</video>
When opened in any browser other than Safari the video loads instantly. I haven't seen it take longer than 5 seconds before it is playing.
When opened in Safari the video takes close to a minute to begin playing (might even be longer).
Can anyone add some reason to this madness so I can:
1) Improve performance on Safari...
2) Get a good excuse to my manager...
I have checked all the video declarations - they are all are working videos.
I have tried moving the order that the videos are declared.
Thanks, Jason.
My assumption would be that the video has default encoding - usually with an mp4 video the final step is to write the MOOV atom that contains the metadata and information about the frame locations etc at the end. This means until the file has been completely read the browser doesn't have all the information available to it.
You can fix this using FFMPEG (open source, free, downloads available for most platforms) and doing a second pass on the video to move the MOOV atom to the front:
./ffmpeg -y -i source.mp4 -movflags faststart dest.mp4
There could be a problem with video encoder. Just run this program to re-encode your video.

Hope this helps.
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'm trying to create a HTML5 video background for a website but I cannot seem to get it to work on Safari. Does anyone have any ideas?
Here's the HTML video tags I'm using
<video id="bgVideo" class="bg__video" autoplay loop>
<source src="./vid/Sample_Vid.ogv" type="video/ogv">
<source src="./vid/Sample_Vid.m4v" type="video/m4v">
<source src="./vid/Sample_Vid.webm" type="video/webm">
</video>
I've tried adding a script tag under it to start playing the video with JS but that's not helped either.
document.getElementById("bgVideo").play();
When I inspect the page it looks like the video element is taking up space in the DOM but it's just invisible basically.
I've also tried opening the .m4v files directly in the browser & it plays it there so I assume the file isn't an issue. These were all generated from easyhtml5video.com
I also have the Modernizer script to detect if autoplay is enabled for the browser which I've had to alter based on a pull request in the github repo as it was always saying that Safari doesn't support autoplay otherwise.
The test site I've setup is http://treetopia.neilnand.co.uk/
The supported video format for Safari is mp4 with H.264 encoding. (you have a .m4v extension and file type)
If video does not has sound - use
document.getElementById("bgVideo").volume = 0;
Safari don't allow autoplay for videos with sound.
For some reason, my video on wordpress wont show up when I use iframe to view it. In I.E., it automatically loads the video into the windows media player versus playing through the iframe.
I am using a local mp4 for the video's. From what I can tell, there's no issues with my I-Frame code. Anyone got any idea's? I cant get it to play in the iframe!
You should not be using <iframe>'s like that. In the past it was a relatively more popular method, but extremely unreliable even back than.
What you should do instead is either encode your video's as .flv's and use flash to play them, or encode them for the 'new' html5 <video>-tag for which no additional plugins are required. To get the best results with the new tag you should convert for 3 different codecs, but H.264 gets you quite far. This is how it ends up looking if you have converted multiple formats:
<video controls>
<source src="somevideo.webm" type="video/webm">
<source src="somevideo.mp4" type="video/mp4">
I'm sorry; your browser doesn't support HTML5 video in WebM with VP8 or MP4 with H.264.
<!-- You can embed a Flash player here, to play your mp4 video in older browsers -->
</video>
And you can read more about it here.
I'm using video.js to embed videos with HTML5 and the video simply plays too fast. I press the play button and I can tell it's at least 1.5x the proper speed.
Any ideas?
EDIT: Sorry! No code. Here you go. By the way, it's copied from videojs.com itself.
<video class="video-js vjs-default-skin" controls
preload="auto" data-setup="{}">
<source src="http://foo.bar/wp-content/uploads/date/video.mp4" type='video/mp4'>
</video>
No webm video for now, I'll work on converting the mp4 to that later.
Also, I'm using this in WP; the admin posts videos that we uploads. No video width, height, poster, or id defined.
Most likely your video is not properly encoded to be compatible with web browsers.
How did you get the video file in the first place
Where does it work
How did you preprocess it for web
