From version 1.8.2 onwards, mobile compatibility is much, much better :)
Mobile detection
Mobile detection is performed on the server once per page load (not per video) and it’s extremely lightweight (excellent performance).
If a visitor is browsing your site with a mobile device the plugin outputs mobile friendly code.
99% of mobile devices can be detected.
Consistent layout
Fixed width videos are not mobile friendly. In this version, not anymore since the plugin will serve fluid width videos (width=100%) to mobiles devices even if you have set a width or height in your shortcodes.
Opera Mobile/Mini special support
Opera browser (Presto engine) replaces video embed codes with an image of the video linked to the phone’s Youtube app. With this in mind, if a visitor uses Opera mobile/mini browser to visit your site, the plugin outputs the html code Opera expects. This way, design & functionality don’t break.
