I'm trying to set up OpenGraph tags on a page containing a video. I'm currently setting up the usual sorts of
<meta property="og:video"...> tags with calls to
drupal_add_html_head(), and that's generally worked fine. The problem is that I'm encoding the video in both .mp4 and .webm formats, so it seems like there should be META tags for both mp4 and webm versions
This is where
drupal_add_html_head() seems to break down. I've tried using it to set up both tags but only the last version entered shows up on the page -- the second call seems to be clobbering the first. I've tried assigning different weights to the different elements, but with no success. Any advice out there? Thanks!
