If you want to hide the YouTube controller then the parameters “controls = 0″ have to be passed in iframe src after ”?”.

Example:

<iframe width="560" height="315" src="https://www.youtube.com/embed/q5jEY92Amgw?controls=0" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
