Ever wanted to send a newsletter with a link to your homepage, but you have a featured video you want to automatically play? With <a href="http://sublimevideo.net">Sublime Video Player</a>, it is pretty easy.
Sidenote: this doesn't explain how to add a video from scratch, just how to make it autoplay. See <a href="http://docs.sublimevideo.net/quickstart-guide">Sublime's Quick Start Guide</a> for help.
I couldn't find any documentation that actually explained explicitly how to do this, but it is quite easy to have a video play automatically. There is a ready event for the video element, and you can simply check if there is a hash tag in the URL and if so automatically play the video. This will work even if you are using the Sublime Video Player as a lightbox.
