Quick question: I have an HTML document playing HTML5 Audio. Nothing fancy. Textbook really.
<audio id="audioclip" preload="auto" loop >
<source src="audio/music01.ogg" type="audio/ogg">
</audio>
The same HTML document features an iframe containing a few Images. Clicking on one of these images browses to a page containing an autostart HTML5 video clip.
Of course now the audio from the parent AND the audio from the iframe video play at the same time.
Is there an EASY way to stop the parent audio playback from inside the iframe automatically when the autoplay video triggers?
I found some pretty complicated stuff for parent/child communication. Far to sophisticated for me. But I also found this little snippet:
jQuery(function($) {
parent.$("#parent_element").trigger(event);
} (window.jQuery));
Could I put that to use in my case?
Or are there alternatives?
Just getting into JavaScript a little more, atm I'd consider myself a newbie. :-\
Many Thanks!
PS: On video end the iframe page automatically browses back to the previous page. It would be super-nifty if the audio would resume playing at the Point IF it was playing before. If not then...well...not. But I reckon that would be much more complex?

Probably a silly question but are there any ways to force playback of a HTML5 <video> earlier than the DOMcontentloaded event?
The video is hardcoded in a liquid file with the following attributes:
<video
poster="./poster.webp"
src="./545645660.sd.mp4"
loop muted playsinline autoplay preload="auto" type="video/mp4" disableRemotePlayback>
</video>
Since it's a hero background video, it needs to start playback as fast as possible but there's about a 2 second delay which looks bad. I've found that disabling JavaScript in Dev Tools will make it load instantaneously so it appears the large amounts of scripts are causing the delay but not sure if there's a way to prioritize playing back the video.
Browsers tend to delay videos downloading u til after all the JS, CSS, HTML, images - since these are required to load the page. Perhaps you can defer some of the scripts to load later?
You could also remove the poster - since that downloads BEFORE the video, and is probably never seen - as the video autoplays.
My team and I are making a custom html video player and I'm working on a setting panel
And the first option we are mainly worried about so I'm adding first is the video quality option.
<video id="video" class="nm" poster="the poster url">
<source src="video source url of the video at 480p" type="video/mp4" size="480">
<source src="video source url of the video at 720p" type="video/mp4" size="720">
<source src="video source url of the video at 1080p" type="video/mp4" size="1080">
</video>
And now what we want to do is when the user toggles on an option it will change the video source to the source that has the quality specified by the size attribute

PS: We are making a video player from scratch as It is on its own built with no APIs (e.g. Video.js, JWPlayer, Plyr) We are making all the things needed from scratch with pure javascript and html... and as we're making a website for streaming, and my team and I want to make a video player made by us for the website, and "maybe" later for distribution but for now we want to make a brand new video player and were just been putting this part off as we aren't sure of the best way to do this!
Edit
Also, we want the video to pause and change the quality and pick up off where it was paused
Note that for the native video the browser will decide which <source> to show and choose the first element it supports/understands (e.g. the first supported video file format): https://developer.mozilla.org/en-US/docs/Web/HTML/Element/video#Usage_notes
To circumvent that and force the browser to show a certain video source url, put in only one <source> element and manipulate the source property with javascript.
To pause and play the video in the native HTML5 video player you may use the API of the HTMLMediaElement: https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement
It has the play and pause functions you're looking for.
I would like to display a webpage with a wall of very short videos:
The videos are 1-2s long and all the same size (about 100px wide)
They are display in the form of a matrix (e.g. 10x10)
Playing the videos is triggered by user interaction (click or hover)
So far, I have tried inserting video tags using jQuery but when I reach about 60 videos, my browser (Chrome) hangs.
My question: is there a trick to display such a large quantity of videos on a single web page and what issue should I look out for to make sure the videos are ready to play before the user starts to interact.
EDIT: I understand this isn't common practice, but this project is an art installation and I need to be able to trigger all the videos (or moving images) on demand and without delay. On the other hand, the initial loading time doesn't matter so much, as the user will be made aware of the heavy load.
Thanks :)
IMO "videos are ready (...) before the user starts to interact" contradicts a leightweight DOM. You cannot have both. I'd try to show thumbnails and initialize the video with the interaction.
you could try to use the
use the
<video width="320" height="240" controls>
<source src="embed Link" type="video/mp4">
Your browser does not support the video tag.
</video>
tag inside of html. then you can acces every object by giving it a tag
I have multiple HTML5 videos <video> on one page. When I play first, it starts downloading. But when I pause or stop it, download continues. When I play next video on the same page, there are two video downloads in the same time.
set the attribut preload="none" in the video tags or preload="metadata" if you want the length and other data upfront.
Question is similar as here. Try to use Media Source Extension.
The title pretty much sums my question up. I've given a cursory glance to https://developers.google.com/youtube/iframe_api_reference and have searched online but all I have found are explanations on how to get an embedded video to autoplay (the first video only) while preventing the suggested videos list at the end. I think that perhaps the logic for playing suggested videos is only supported on youtube.com itself, a conclusion that might be supported by the autoplay button being outside of the video element.
As a worst case solution, I thought maybe if I could save a youtube.com page to my desktop I could modify the styling to only show the video. But alas, the page breaks when I try to load it from my hard drive as opposed to the website.
Edit: Take note that I'm talking about two different types of autoplay here. One is the autoplaying of suggested videos as seen in the picture, and that is the type of autoplay I want to be able to use in an embedded player. The other type of autoplay that I don't need help with is getting the embedded player to automatically play the video that is contained in its iframe src, aka the first video.
Since you marked iframe under your tags and I can't comment, I will try to answer.
If you're using iframe then make sure
autoplay=1"
is on
<iframe id="ytplayer" type="text/html" width="720" height="405"src="https://www.youtube.com/embed/M7lc1UVf-VE?autoplay=1"frameborder="0" allowfullscreen>
I found a link that will build it for you. It was a bit into the api link you gave.
https://developers.google.com/youtube/youtube_player_demo
You can give it the video and tell it what you want it to do.
