YouTube Embed Plus plugin
I’m working on a site that needs a lot of embeddable videos. I first tried self-hosting them, but got an ominous “Waiting for available socket…” message that made me think that was eating too much bandwidth, so I uploaded them to YouTube.
I’ve dealt with YouTube embeds before and found good plugins for making them responsive, but this one‘s in a different league: it ships with about 30 more options than I realized even existed for YouTube embeds. Just make sure you check the options that matter to you—particularly the “Responsive” option, which is 80% of why I wanted the plugin in the first place, and which is unchecked by default.
