I have an expression that loads a video and an image depending on its mediatype in the url under the style part in the extended properties. However, I am unable to stop the autoplay or manipulate the size of the video player at all. I have tried separating them and using an if statement to detect the media type and place them in either an image holder of html5 video player but it doesn't seem to work. Please help.

Hi Amos, welcome to OutSystems!

Could you please post a simple module so I can take a look the code?
