Multimedia



Three main types of multimedia exist on the web images, audio, and video. HTML5 has three tags to include, or embed, these elements into a web page:

  • <img>
  • <audio>
  • <video>

Images

The image tag <img> has one required attribute and several optional attributes. The image tag requires an image source attribute to be present. It is also important that images also provide alternate text so that all users can be aware of the image content.

<img src="http://example.com/image.webp" alt="Example image." />

Images can be given additional attributes including width, height, and a couple of attributes relating to image maps (images with specific interactive areas).

Open image formats include PNG, JPEG, and WebP.

The GIMP is a free photo manipulation tool that you can use to create and edit images for your web pages and even create web layouts. Inkscape is a vector graphics (i.e. SVG) illustrator that can be used to create images, web pages, layouts, and other vector based projects.

Audio

The <audio> tag is new  in HTML5. It gives designers a standard way to include audio in a page. The <audio> tag has several parameters the most important of which is source:

<audio src="file.ogg">Text for browsers that do not support the audio tag.</audio>

Other  attributes for the <audio> tag include autoplay, controls, loop, and preload.

Ogg Vorbis is an open format for web audio and is supported by Mozilla Firefox, Google Chrome, and Opera.

Several free tools exist with support for Ogg Vorbis audio:

Video

The <video> tag is also new in HTML5. We can now insert video into a web page without the need for third party plugins! The source attribute is key to the video tag:

<video src="video.ogv">Text for browsers without support for the video tag.</video>

Additional attributes for the <video> tag include audio, autoplay, controls, height, loop, poster, preload, and width.

Ogg Theora and WebM are open formats for Internet video both of which work on Mozilla Firefox, Google Chrome, Chromium, Konqueror, and Opera. Several free tools exist to convert new and existing video to Ogg Theora and/or WebM including:

It is possible to offer alternative formats for browsers that do not support Ogg Theora or WebM. To do this, you nest multiple <source> tags within a <video> tag as such:

<video>
  <source src="file.ogv" type="video/ogg" />
  <source src="file.webm" type="video/webm" />
  <source src="file.mp4" type="video/mp4" />
  Text or markup to display if the video does not play.
</video>

There are also several video hosting/streaming communities that support open formats:

    It seems like it isn't enough to put the source, you have to add:

    preload="preload" controls="control"

    to the audio and video tag.  Other than that no problems.

    Finally got a simple example of video, image, and audio to work.

    It turned out that I needed codecs with the video.  I'm not sure why.  It seemed like other people did not need them.  I found tham on html5rocks (http://www.html5rocks.com/en/tutorials/video/basics/)

     

    For the image, I was using a photo which was a large jpeg.  I had to reduce its size to make it work.

    The audio worked with no problems.

    El problema que veo en la utilización de la etiqueta video, es que para cada navegador, necesitamos un formato de video diferente, con lo que esto aumenta considerablemente ya no el trabajo de convertir los videos a mp4, ogg o webm, si no que los hosting de nuestros servidores, se van a llenar de el mismo video, pero con extensiones diferentes, con lo cual, el peso de este va a aumentar considerablemente.

     

    <video>
                  <source src="demo/videos/tabarca.mp4" type='video/mp4; codecs="avc1,mp4"' /> <!-- Chrome -->

    But I can't run the audio or video tags in Explorer versions under 9.x (P.E. Internet Explorer 8). Do you know any way to run in all of the browsers (at least in the generalists).

    Hello José,

    the  problem with your could be the single type of audio and video. There are two different types of audio files that you can add in your HTML code ( .ogg / .mp3 ) I suggest you to put both of them because IE doesn't support .ogg files, but it supports .mp3 files, so that means you need to add both of them. Ogg is for the webkit browsers and mp3 for IE. You can do it like this:

    <audio controls="controls">

    <source src="file/example.ogg" type="audio/ogg">

    <source src="file/example.mp3" type="audio/mpeg">

    TU NAVEGADOR NO SOPORTA HTML5 - Estarías escuchando La Marcha Granadera, el actual Himno de España

    </audio>

    So that means that you need to have both types of files and if you put them both in your code the browser will be able to recognise the file it supports.

    The same thing is with video, only difference is that you have to put three types of files ( .ogv / mp4 /  .webm):

    <video controls="controls">

    <source src="file/example.ogv" type="video/ogg">

    <source src="file/example.mp4" type="video/mp4">

    <source src="file/example.webm" type="video/webm">

    TU NAVEGADOR NO SOPORTA VIDEO OGG - Estarías viendo como se unen 2 cables con una fuente de calor

    </video>

    Try it, I hope it will help...

    I changed the doctype to fit html5 and cleaned up meta section.  I was watching one of Stanford Uni's videos, and in it the speaker said all the junk I had in <!DOCTYPE html>  was now outdated.

    joe palmer said:

    Yes on the u, I should have probably said go to view source but the new Firefox does not have that in the toolbar anymore and that is how you view source now in Firefox, hold cntrl hit u and the view source window pops out. Inbetween classes, sorry can't do more, was curious to this also, I bet if  you view source on some of these others you will see what needs a tweek, but you must have or you would not have seen Alcinoes. Oh, what browser do you use? Try another, than you may have to find what they put in to support the browser that you do use, IE is famous for having to add extra things into the code to get what Chrome or Firefox do on thier own.

    I put your view source next to one that works and can't figure it yet, but your tag for charset = "utf-8" should not have a / end hash in it, it is always soemthing real little thing that throws things off...recheck your audio source?

    Anybody????

    I ran my file through the online markup validation service.  It didn't complain about the / after utf-8 or any part of the audio coding.  It doesn't like the comment before <!DOCTYPE>.  The only complaint it had was about the stray end tag for </embed>, which doesn't make any sense to me.

    I use FireFox.  I've looked at the source code of all posters a few days ago.  Some of them have the same problem as I.  I'll look at each one more carefully.

    Your audio works for me now, it sounds Yiddish or something, a man not speaking in English. What version FF do you have? Lets just say it has to be at least version 3.5, but they are all the way up to versoin 8 now, so maybe you should go to the Firefox website and download the latest version, your bookmarks and all will remain. I bet that is what it is, let me know.

    I think that you need to look at the audio files themselves. They must be named jer1.ogg and jer1.mp3. in order for them to work. Also, if your original file was mp3, you need to use a converter to make it into a ogg file (and vice versa). 
     
    I think that your ogg file is named jer1.ogg.ogv. That would actually make it look like a video file, and because it is not named properly, it can't be found. I think that this is why it is not playing in Firefox. It is fine in Chrome because Chrome looks for and finds the correctly named mp3 file. Firefox does not support mp3 so it looks for and can't find the ogg file.

    I think Alcinoe figured out the problem. Here is another site to see stuff, and I Google tags themselves with HTML5 on them (embed tag HTML5), I might catch bad for this but I do steer clear of W3C school, they have nothing to do with the real W3C. You'll know good sources when you see them, the trick for me is balancing learning with doing, what good is the reading if I'm not making something. There are good ideas in here too fish out and see, tons...

    If you want to save the file, right click and hit "save audio as"  It iwill add an ogv to the end of the file - this needs to be removed. I also renamed it to jer2.ogg so you either have to change the file name or change it in your code.

    For audio, do I need to convert mp3 to ogg in order for the audio tag to work?  That seems like a bad thing to do, because converting from one lossy format (mp3) to another (ogg) will degrade the sound quality.  Are there any other ways to add mp3 to my web?
