i try to use mediaelement.js, which i think is a great player solution, but the problem is that above the video player (which displays well) i get these warnings :
Notice: Undefined variable: type_attribute in /homez.110/.../media-element-html5-video-and-audio-player/mediaelement-js-wp.php on line 275
(and for the others variables too :poster_attribute, autoplay_attribute , mp4_source, mp3_source, flv_source, wmv_source , ogg_source, captions_source, loop_option, videohtml)
Where is my mistake?
thanks in advance
