I would like to start off by first saying that I am not a web developer so I apologize if I explain thing poorly.
I am working on a simple in house digital signage solution. We create the show in power point, then save it as a video. We then loop that video on a webpage.
<video autoplay loop muted id="video-bg" preload = "auto"
style="position: fixed; left: 0; bottom: 0; width: 80%;
height: auto; z-index: -100;">
<source src="./test.mp4"
type="video/mp4">
</video>
This is the code used to play the video, extremely basic but it is all we needed.
To update the show we simply overwrite the existing video and when the page auto refreshes the new video is played. This works when the site is being displayed in Chrome. In IE we can not save the file as we receive an error it is in use.
Using process explorer I see that the file is in use by IE but not Chrome.
Is there a difference in how Chrome and IE use a file?
Thanks in advanced to anyone who can help narrow down this problem.
I did not research about this topic but probably Chrome is caching your video and playing it from the cache. However you can try to force the cache behavior, take look at: HTML CACHE and see if it works in I.E.
Add the manifest.cache in your html tag:
<!DOCTYPE HTML>
<html manifest="manifest.cache">
And include the manifest.cache file in your folder:
CACHE MANIFEST
/test.mp4
I hope that I helped you.
Rather than just opening the webpage into the browser we are using The Uniform Server and hosting the page locally on the computer.
Doing this allows us to overwrite the file regardless of the browser we are using.

I am new to HTML and CSS (So that may be the issue). I entered the following code into my html doc:
<video controls width="700">
<source src="video/PristineCustomCleansVideo.mp4" type="video/mp4">
</video>
The video I want to play is inside a folder called video. The index.html and the video folder are nested inside a folder together.
The video shows up on the site I'm making as a gray rectangle with controls (in a Brave browser). When I press play nothing happens. I also tried opening my page in Firefox and within the gray rectangle it says "No video with supported format and MIME type found."
I looked up this question and have found so many confusing suggestions. Whatever you recommend, please do it as if I know very little about computers (I thought I knew a good amount until reading some of the responses and can't follow what I should do. lol)
Another issue I am considering is if I have to do a lot of work to get the video to play, will others that I send my website URL to have issues as well? This is for a class project. I have to put everything on the school's server and share the URL with the teacher.
If your index page and the video are located in exactly the same place you do not need the video folder in the path to your file. The following should work.
source src="PristineCustomCleansVideo.mp4" type="video/mp4"
I attempted to add a Hero background video to our website. It's being served from mux.com.
I use it with HLS, but for Chrome it uses Media Source Extensions from what I gather.
I know that for HTML5 video to auto play, it has to be muted also, and I have both parameters over there.
Apparently, on Android Chrome I get behaviour where it freezes on the first frame (black), but doesn't continue and I cannot trace why.
In case of freezing, it still does load the video, just that it's not getting autoplayed.
I am out of clues.
Isolation sandbox:
https://codesandbox.io/s/32yky6x7mq
https://32yky6x7mq.codesandbox.io/
In my attempts, I have reduced this down to simple HTML app with Hls.js library and basic <video> tag where it breaks on mobiles.
How do I get the video to autoplay on mobiles?
P.S. To see exactly what I have tried, please see edit history, as I have been trying lots of things.
On my device specifically, Android Chrome, it's caused by Data Saver.
Disabling Data Saver, the video autoplays.
It's paradoxical, because with Data Saver I expect for the video to not be loaded at all, but it's getting loaded and the autoplay gets interrupted instead - resulting in more waste.
Possibly, there are other settings out there in the wild that prevent autoplay, for instance, couldn't find the exact reasons why iOS is not working. There are hints about playsinline attribute, which I have not tested yet. (Will update when I do)
Worth noting, is Feature-Policy header too: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Feature-Policy
It didn't help me in my scenario, but it can probably be related with autoplay in other scenarios.
I have a page that displays multiple videos using html video tags. The code looks like the below snippet:
<video controls="controls" class="vw" name="Video" src="videos/ACS_Video_2b.mp4"></video>
The class is simply a class that dynamically sets the width, height, etc.
The video looks and plays very nicely in all browsers except for Firefox. All of the videos on the website using these tags are upside down in Firefox. I can't seem to find anything online about people having similar problems. In fact, when I go to other websites using identical video tags and video extensions, etc., the video displays perfectly on their site for me in Firefox.
Here is the website with the upside down videos for reference:
http://www.larrykrannich.com/video.html
The videos display upside down locally, on a local server, and hosted on a real server.
Any help would be greatly appreciated.
This is a firefox problem, I have seen that several people have complained over and over about this problem but all to no avail. it only happens when the video is recorded from mobile, firefox doesn't seem to use the camera details to encoded rotation that came along with the mobile video. for the main time you have to figure out a fix for yourself, you can use css transform to rotate the video tag, but one problem with that is that it will rotate the video control with it.
you can use videojs, then add the rotate plugin, you can just google it. it will help rotate for video.
you can do something like this
if ( isfirefox ) {
<video class="video-js vjs-default-skin" controls preload="auto" width="270" height="360" data-setup='{ "plugins": { "zoomoomrotate": { "rotate": "270", "zoom": "1.4" } } }'>
<source src="video-source" type="video/mp4">
</video>
}
also, there is a recent issue in chrome update that compress mobile video as well. still looking for a fix for it
It seems to have something to do with rotation metadata in the video files. The problem can be solved by transcoding and rotating the video. Similar post here
Most likely, you have recorded the video upside down, without realizing it - which can happen, e.g. when using a smartphone-camera.
There are video-players, that auto-correct for such things, which might be, why you didn't realize the video being upside-down.
There is a free Videoplayer called VLC, which you can correct this with by rotating the video.
Get it here and install it, if you don't already have it:
http://www.videolan.org/vlc/
Steps:
Open video in VLC media player
Pause the video, if it's too short to keep running, while you perform the other steps
In the upper menu, navigate as follows:
Tools
Video Effects
In the window, that just opened go to the Geometry-tab and do the following:
Check the box "Transform"
Select "Rotate by 180 degrees"
Your video should now look nice and right side up
To save your changes:
In the upper menu click, navigate as follows:
Media
Convert/Save
Choose, where you want to save the file.
Upload the rotated video in place of the upside-down one.
Now your video should be displayed correctly :)
I just noticed that Chrome (Version 45.0.2454.99 m) basically reloads a video each time it loops. This occurs with even the most narrowed down version of my code :
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body>
<video autoplay="autoplay" loop="loop">
<source src="myvideo.mp4" type="video/mp4" >
</video>
</body>
</html>
This occurs independently of the hosting technique (tried local, Google drive and 2 classic hosting solutions) AND is not related to cache-control HTTP headers, those only ensuring the video isn't reloaded from the source each time but from the client-cache.
As it seems to be a Chrome bug and I can make this not too visible for the user I could live with that, but still, on airbnb website, they have a header video looping and NOT being reloaded by Chrome. I tried mimicking their HTML which isn't much more complicated than the example above, video gets reloaded on each loop, so I know for sure there must be some kind of workaround for this implemented on their site. Their JS code is minified though, therefore very hard to debug and I don't have even the beginning of a clue on how they do it. So my question would be: has everybody encountered this issue and found a workaround he could share with us ?
This could be caused by having "disabled Cache" ticked in the Chrome Developer Tab.
If not, you can use the App Cache to fix or service worker to load the video from Cache.
This issue was covered here:
Why html5 video loop create request each iteration
Probably fixed in newer version of Chrome
Just as the title says. I've been working on a site and had added a big html video for the main page.
I looked over online...myme types checked, h264 encoding checked. I looked over old versions of the file i've been working on and noticed an old pure HTML file which loaded the video in all browsers with no problem (which I guess discards any encoding or video quality issues)
It all was working neat. Even displaying in firefox, chrome an IE. BUT for some reason the video does not load in IE whenever the file extension for the page it's on is .PHP. To be precise, whenever i try it from my LOCALHOST (XAMP with Apache server)
I also checked the dev tools and under network it does show it as the right content type and no error whatsoever (getting normal 200 result)
Here's the snippet of the video tag used:
<div id="video_container">
<video autoplay loop poster="video.jpg" id="header_vid">
<source src="imagenes/video.mp4" type="video/mp4">
</video>
LOL, and just noticed...not even the poster image is showing in IE...wtf.
I'm so confused, could anyone enlighten me a bit please? Could it be something related to the path used? been digging around the net for days _
Check if your url is formed properly when you are using .php extension on IE. Same issue addressed quite a few time here.

Play mp4 file through php in HTML5 Video Tag in Chrome?
I notice IE doesn't like the properties without value, so try
<video autoplay="" loop="" poster="video.jpg" id="header_vid">
