Embedding on a WordPress site is easy. First, change from "Visual" to Text (on newer versions of WordPress)/HTML (on older versions of Wordpress) as in the example below:
After clicking to change the mode to Text/HTML, now enter in your iframe code (found under PUBLISH SETTINGS) into the article like below. Where you enter the code will dictate where it appears on the webpage.
Once published, the area will become an active video player element that will playback either your on demand video file or your live stream.
