Youtube Video Embed New Code Iframe (2010)

In 2010-07, Google introduced a new HTML format for embedding youtube videos.

Old Code using “object” Tag

This is their older format using the “object” tag:

<object width="480" height="385">
<param name="movie" value="http://www.youtube.com/v/h7XjOK_DSmo?fs=1&amp;hl=en_US&amp;rel=0">
</param>
<param name="allowFullScreen" value="true">
</param>
<param name="allowscriptaccess" value="always">
</param>
<embed src="http://www.youtube.com/v/h7XjOK_DSmo?fs=1&amp;hl=en_US&amp;rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385">
</embed>
</object>

there are several problems.

• Closing param tag is invalid. Param is self closing tag.
• Embed tag cannot be inside object tag.

The following is modified code so the result is valid HTML:

<object type="application/x-shockwave-flash" data="http://www.youtube.com/v/h7XjOK_DSmo" width="480" height="385">
<param name="movie" value="http://www.youtube.com/v/h7XjOK_DSmo">
</object>

New Code Using “iframe”

The following is the new iframe format they are offering:

<iframe title="YouTube video player" class="youtube-player" type="text/html" width="480" height="390" src="http://www.youtube.com/embed/h7XjOK_DSmo?rel=0"></iframe>

The new format using iframe is much better, because, according to Google's youtube blog at http://apiblog.youtube.com/2010/07/new-way-to-embed-youtube-videos.html:

If you use the new embed code style, your viewers will be able to view your embedded video in one of our Flash or HTML 5 players, depending on their viewing environment and preferences. …

An additional benefit of the new embed style is that it will eventually allow embeds to work on mobile devices, which typically use a built-in player instead of Flash or HTML 5.

The iframe is also better because:

• The actual video HTML code is fetched when user loads the page, so you don't have to worry about keeping up-to-date of all your hardcoded embedded video codes on your site, in case any youtube format changes in the future or youtube embed feature changes. When HTML5 comes alone, nothing you need to change on your site.
• You don't have to worry about browser compatibility of your embeded video code now. Google takes care of that.
• The iframe tag is shorter and simpler.
• If you are a HTML validity worrywart like me, with iframe you have less to worry about. Technically, there is no type="text/html" attribute for “iframe” tag, so Google's new HTML is still incorrect, but it's far better than the extremely complex “embed” tag, or manually crafting and maintaining the not-widely-supported “object” tag.
