Simplest video plugin to use i've tried..
However you will need to manually edit the mime types required for Smartphones etc.
Or to make your life easier download and FTP to plugins: PJW mine config V1.00 to enable for example "webm" uploads into your Media Library.
Used on a test site first and found no issues with editing mine types with WP 3.50
Tested 20MB ogv /20 + 200MB MP4 / 20MB webm & all worked.
