I want to create a html5 page with video and an image overlay - meaning some image that is showing over the video. This overlay will in time also be text in some cases. Is there any good way to achieve this?
What I've been trying this far is to use a <video> tag to hold the video, and draw the image into a canvas, which I place on top of the video. To show it I need to move the video back setting z-index to -1, but then the video controls won't work. Maybe there's a solution to make the controls work again, but I'm not sure if I'm on the right path here.. I am assuming there is a recommended solution to this. Maybe using a canvas which I fill both video and overlay into. Or something completely different?
Note: I edited the question as it originally pointed in the wrong direction regarding what was important here. I'd love to have a solution which makes this work seamlessly in fullscreen and everything, but the focus is: What is the appropriate way to place items on top of video - in html5?
Achieving what you want and have it supported in out-of-the-box fullscreen is problematic. Fullscreen support in html5 video is only optional and in any way not accesible thorugh the API (See discussion here).
Even if you used the built in fullscreen there is no way you could inject content above it unless you are willing to change the video file itself on the server in runtime.
what you can do however (And what I did in a similar case) is to implement your own video controls, run the video tag without the built in controls, and have fun with overlaying as many layers as you want on top of your now out of focus video.
As for fullscreen, you can implement some sort of custom background fullscreen similar to what's been done here
edit: The problem you're having by placing a canvas over the video is blocking the built in html video controls. My suggestion is to implement your own video controls (play, pause, volume, seeker, etc.) using html and javascript calling the video API. You can probably even make it prettier then the ugly built in controls.
Your controls can be contained in a layer above the overlaid canvas, and thus the video will be shown, above it the overlay and above it your control set.
You can read a little about implementing your own controls here or here
And anyway this can easily be much better than this.

I'm looking for a way to make it so that even if a site tries to "hide" the video controls for a video, I want to override this and have the controls.
There's little more frustrating than wanting to get to the point of a video and having to sit through 15+min of BS/Advertising to get the 60seconds of content you care about.
I see many posts asking how to hide these controls, so playing devils advocate, how do I override this and make it always visible? Addin for browser? HTML code insertion? How about on mobile?
I want to display captions using the HTML5 Text Tracks API (WebVTT) using the native browser implementations -- without loading audio/video.
How can that be achieved ?
There is no way using the native implementation.
However, the Firefox implementation of WebVTT, vtt.js, is publicly available.
All you need to do is attach a timer while a video element is playing (or just to any custom event without a video) and apply vtt.js functions to the video / captions container.
Since the Firefox VTT implementation is derived from it, this is the closest you can come to native without using the default way of attaching to a video.
I have a webapp written in HTML5.
The Home page contains a <video> tag.
The video is correctly played when I load the page for the first time, and if I use controls (pause, play, fullscreen) too.
In order to maintain the webapp always in the fullscreen view, I used only one html page, and when a button (or an anchor) is clicked, I hide the container div (representing the content of the logical "home page"), and show the selected one, when the "home" button is played I show again the original container div.
Originally, the video continued playing when I clicked a button to pass to another virtual page, so I pause it by jquery.
The problem is: only on iPad, when I come back to the first container (that means the home page), the video is no more available, I can't see the poster and the video itself, and the div is black screen.
Some notes I hope could restrict the problem:
The video is statically loaded in a <video> tag and source
attribute.
I've tried to start with an empty src and load it by
jQuery (as explained in many tutorials and in stackoverflow too), it's the same.
The same if I try to create a playlist in
which I select different videos and load the selected one in the
<video> tag using Javascript.
I also tried to reload the page with jQuery, but doesn't work.
The constant beahviours are the following:
Every technique I tried to implement is working well on PC with
Firefox and on the Mac with Safari.
The problem on the iPad appears only when I try to come back to the initial page.
I'm not convinced the problem depends on the technique of show/hide I used, but on the iPad behaviour. I've read some other ways to maintain the webapp in fullscreen view, but apply only to <a> tags (such as this:), I need div stylized as buttons (and managed in jQuery) too.
Thanks if someone can help
I think if you use flowplayer is better it is good implementaton that it work on IPhone and Andriod, it is free.
I have video that will be divided into 4 videos.
First the player will stream a lower resolution of the original video, then the user can zoom into the video to see more details, I need the player to stream one of the 4 videos - that's higher in resolution- based on where the user zoomed in.
How can I make that using VideoJS or any other video player ?
After searching, this is the answer ...
For zooming into the video, you can follow this tutorial: Zooming and rotating for video in HTML5 and CSS3
For switch streaming of videos in the same player, you can make that by changing the source on html5 video tag and make some calculations to know where the user zoomed in and hence change the source video.
As there is no response yet let me analyse the problem. This is by no means meant as a full answer, but other people will probably be able to answer parts of the problem:
First the player will stream a lower resolution of the original video,
This means you will need to create/use a video stream. There are plenty of plugins you can use for videostreaming, and depends on what you want. You can consider writing it yourself using for example C#'s System.IO objects and transforming the video in bytes(And putting it back together) The resolution would be easiest reached by just having a seperate video file for this step of the proces. (a lower resolution one used for streaming only)
then the user can zoom into the video to see more details, I need the player to stream one of the 4 videos - that's higher in resolution- based on where the user zoomed in.
So you need to trigger a zoom effect. This means you would need to detect zoom. This would be possible with Javascript in a webbrowser, if you want a browser based application. When that zoom is triggered you can retrieve what position the mouse is on the screen/in the div or on some sort of overlay. Depending on this position you could show another stream.
How can I make that using VideoJS or any other video player ?
Basically these steps above is how i would start looking into this specific case. Considering your VideoJS as a suggestion i assume this is browser based. This would probably mean using Javascript libraries, maybe combined with a server side language.
Thats as far as i can go. Maybe someone can pick up specific parts of the thing i wrote and help you a step further.
Have a nice day!
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.
