Based on my reading of this article on Google's developers' site, and my memory of how my site used to work, it seems like lazy loading has become the new default. That's cool! However, I'm running a site that people use to browse a media library, and lazy loading adds a bit of visual jank, so I'd like to disable it in this case.
I understand that I can add loading="eager" as an attribute of the img tag, however, the way my site works is i display a grid of 60x video elements and use the poster attribute to display an image until the user hovers over and then a super-low-res video preview plays.
loading="eager" doesn't seem to work for the posters of video elements. What should I do?
Here's my codeblock:
<video loading="eager" class="hoverToPlay" muted loop
preload="none" src="../media/?clip=1297&q=q"
poster="../media/?clip=1297&q=t"></video>

I have videos on my website that are taking very long to load.
I don't think it is my webhost since it also happens on localhost.
Each time there is only 1 video shown to the user, depending which category they chose. (So it is not loading each video always).
The videos that take longer to load are the bigger ones (the biggest one is about 351MB video file)
This is my html code for the video:
<div class='video'><h2>$vidTitle</h2><video width='640' height='360' controls preload='metadata'><source src='$viddir' type='video/mp4'></video></div>
I've also read that it could be that the video indexing could be at the end, could this be the case?
What can I do about this, do I need to use another player thann the default html5 player (I tried this but it didn't really help) | do I need to use a cdn?
How can I solve this?
Thanks!
My understanding is that the preload='metadata' attribute in your video element is supposed to prevent the video from loading.
You could try preload='none' to test. I know that works.
As always, a good place to check is MDN web docs:
mdn web docs : The Video Embed element
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.

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 am using the video tag for my page, and I am trying to exclude the fullscreen from the controls.
I see that the "controls" in general is only a true/false statement, but i am looking for a way to disable the fullscreen option from the video.
I could do controls false and use autoplay the video - Then i have no controls - and the video will just play.. - but i think this is too drastic a "solution".
So what kind of solution can be done to achieve what i am looking for ?
For browsers that incorporate a shadow DOM (e.g. newest version of Chrome), you can still use the default controls, but hide the fullscreen button.
Just be sure to include the following in your CSS:
video::-webkit-media-controls-fullscreen-button
{
display: none !important;
}
As shadow DOM manipulation like this becomes more commonplace, more browsers will hopefully support it. Until then, stick to making custom controls or putting the video within an iframe as long as your src points to an html file with a video tag in it, and you specify allowfullscreen="false"for the iframe.
controls is a binary state, you either have what the browser provides or you have nothing.
If you don't want the browser to provide a full screen control but still want a UI, then you'll need to turn controls off and implement your own UI with JavaScript.
I'm trying to create a video pop-up that works on Apple devices and I've been playing around with fancyBox & some YouTube videos. Because YT uses Flash, this isn't going to work (which I am just now realizing)
Is there a way to open up an html5 video inside of this pop-up?
I already set that part up:
Here's the page where I'm already using fancyBox: http://legal-replay.com/video-test/
Please help!
<a class="iframe" src="http://www.youtube.com/embed/dP15zlyra3c?html5=1">Open HTML5 Video</a>
I don't know much about fancybox but it looks like you can just have it open any iframe you want, which will work with YoutTube's default embed method. Just pass html5=1 to the iframe.
From what I can tell scouting around stackoverflow, this is only supported for single videos, I don't know if you can force an entire playlist to use HTML5, that might still be a client-preference.
