How can one ascertain the dimensions of the video margins within an embed-responsive video container?

I am in search of a solution to extract information from within the embed responsive element.

When it comes to embed-responsive video elements, they automatically include internal margins on either the x or y axis to maintain the aspect ratio of the video. These were commonly referred to as 'letterboxes' during the early days of 16x9 aspect ratios. How can I determine the size of these internal margins/letterboxes?

Despite conducting thorough research, I have been unable to locate any relevant information online or on stack overflow.

Currently, I am immersed in a substantial Angular 7 project and do not possess any code to share since this query is more on the conceptual side.

I'm seeking assistance from a true front-end expert to guide me through this issue.

Thank you!

Answer №1

Instead of the standard large video container with its own responsive letterboxing, I chose to place the video in an intermediate container and utilized CSS calc to determine the height, ensuring a perfect aspect ratio. This method maintains the embed responsive effect without any letterboxing. Additionally, by adding a label or overlay, it will maintain the exact size of the video.

height: calc((100%*3) /4);
