Stream Video in slider?

Which theme or plugin are you referring to? There are some plugins, like the pro version of Meta Slider, that allow playback of embedded videos, but it just depends on what theme or plugin you are talking about.

sorry did I post this wrong? I’m using the Customizr theme.

You didn’t post it wrong, you just posted it in the wrong place. Post another question on the Customizr support page, and someone there should be able to give you an answer (scroll down to the bottom of the page to enter your question).

Thanks for the tips! I thought that was where it had posted but apparently not.
