[Plugin: MediaElement.js – HTML5 Video & Audio Player] Embedding YoutubeVideos?

I had same problem, but with vimeo. It’s because the plugin’s php file (mediaelement-js-wp.php) didn’t reference or generate the youtube or the vimeo video code. So I added it for my install. Here’s my vimeo/youtube enhanced version of the mediaelement-js-wp.php file.

Cheers!

I just now had a chance to try this out and it works awesome. Thanks so much for taking the time to do that! ??

Thanks – I too had this problem, and your updated code has fixed it for me too. Many thanks.

This is great! Thanks – works great!

Any idea how you might make the auto start functionality work with Youtube and MediaElement.js?

This doesn’t appear to work:

[video width="640" height="360" type="video/youtube" src="https://www.youtube.com/watch?v=nOEw9iiopwI" autoplay="true"]

This works great — but has the Youtube skin:

<embed src=”https://www.youtube.com/v/EBM854BTGL0&autoplay=1&rel=0&#8243; type=”application/x-shockwave-flash” wmode=”transparent” width=”425″ height=”344″></embed>

Dear d8n, your solution is not working with the new plugin upgrade 2.27.0.
