Video previews aren't muted

[khafa100]

I am addressing this issue in this story: https://trello.com/c/uC93HAje

Things I have tried so far:

• I attempted adding both mute: :mute and muted: true to the following line (despite it being content_tag and not video_tag) to see if it would work but it had no effect.
  • https://github.com/chapmanu/signage/blob/development/app/views/slides/_form.html.erb#L255
• I attempted changing content_tag to video_tag but that just broke the slide.
• After inspecting the code on the live site I noticed a video tag under the iframe tag but have yet to locate an actual video tag in the source code.
• I looked into the possibility of using javascript to mute the iframe with a few suggestions from the following stackoverflow's but they either don't work or I'm putting them in the wrong place.

I found the video tag in the following location:

• https://github.com/chapmanu/signage/blob/development/app/views/slides/templates/_standard.html.erb#L20

I added controls muted to the html (reference found here):

This is working properly and mutes the video while only altering the code in a single location rather than attempting to alter the content_tag in two different locations.
