If you are having problems trying to display an embedded video(s) in your posts like me, then this might help you out. I usually embed videos from Hulu, Vimeo and YouTube mostly. But it’s been a problem trying to have the latter 2 display in fullscreen mode.
For Vimeo, the fullscreen icon/grpahic displays on the overlay of the video. But pressing on it, just pauses the video and nothing else. For YouTube, there was no fullscreen icon/graphic in the first place. I think that might have been caused by some code changes on YouTube’s end.
Meanwhile, it seems that the author of Video Embedder, Kristoffer Forsgren, hasn’t been able to update the plugin since 2009. So for those like me who still finds good use for the plugin, it was a let down not finding any new comments/updates since August of 2009.
