While working with the product, I found three errors of the HTML in the method add_videojs_header found in the video.js file. I don't know the proper way to submit suggested code fixes, so here it is.
19: /* Include the script and css file in the page <head> */
function add_videojs_header(){
20: $options = get_option('videojs_options');
21: if($options['videojs_cdn'] == 'on') { //use the cdn hosted version
22: echo "";
23: // 09-22-2012 mophilly; added script type on line 27 and tag terminating slash on lines 26 and 31
24: echo '
25: <link href="http://vjs.zencdn.net/c/video-js.css" rel="stylesheet" />
26: <script type="text/javascript" src="http://vjs.zencdn.net/c/video.js"></script>
27: ';
28: } else { //use the self hosted version
29: echo '
30: <link href="' . plugins_url( 'videojs/video-js.min.css' , __FILE__ ) . '" rel="stylesheet" />
31: <script src="' . plugins_url( 'videojs/video.min.js' , __FILE__ ) . '"></script>
32: ';
33: }
34: }
