First, great plug-in!
I am trying to get this to work with a new 3.4.1 WP site, so 3.4.1 may be my problem but here goes.
Simple shortcode test: [video mp4="test_file.mp4"]
Video "test_file.mp4" is in the main directory for the WP installation. Video plays in FF, Chrome and Safari without any issue. IE shows a static loading animations circle but nothing happens.
I read through some posts and added in the mimetype for MP4s using the .htaccess file but still no luck. I have also tried this on a locally installed version of WP and on my actual server, no difference.
I have also tested the MP4 file on other sites using Video.js and it plays with no issue, so I know it is not the MP4 file.
Any ideas on how to get this to work with WP 3.4.1?
