Broadcast Live using an iframe
If for whatever reason you want to use an iframe as a webinar source (because your desired integration isn't listed for example), you can configure that also.Place the source URL of your iframe on the ‘live page’ settings of your webinar. Make sure the webinar type is configured as ‘Inline Frame (iframe)’, and save your settings.
You will have to only place the url of the source and not the entire iframe code.
The "Video Autoplay" and "Show controls" settings won't have any effect on the iframe.
