Displaying videos in full screen using HTML5

I am attempting to create a fullscreen webpage with a video using the following code:

 <video  id="backgroundvideo" autoplay controls>
            <source src="{% path video, 'reference' %}" type="video/mp4">

        </video>

Here is the CSS I am using:

  #backgroundvideo {
            position: fixed;
            top: 50%;
            left: 50%;
            min-width: 100%;
            min-height: 100%;
            width: auto;
            height: auto;
            z-index: -100;
            -webkit-transform: translateX(-50%) translateY(-50%);
            transform: translateX(-50%) translateY(-50%);

        }

When trying to view the page on my Android phone (5 inch), the video does not display properly, but it works fine on an iPhone 4. I suspect there may be a css-related issue causing this problem.

Could you provide assistance in fixing this issue or suggest another solution?

Answer №1

If you're experiencing issues with your video not working, it would be helpful to provide more details so that I can assist you better. However, let's take a look at some possible solutions:

    top: 50%;
    left: 50%;

When going fullscreen, positioning the video at 50% down and 50% to the right may seem odd. Consider using top: 0; left: 0; for a more logical position. Am I overlooking something here?

   min-width: 100%;
   min-height: 100%;
   width: auto;
   height: auto;

If you're aiming for fullscreen display, specifying min-width and min-height as 100% might be unnecessary. Instead, try using width: 100%; height: auto; for a better fit. Keep in mind that this could result in bars appearing due to aspect ratio differences.

Video support can vary greatly across different browsers, and your code might be causing confusion for the browser.

-webkit-transform: translateX(-50%) translateY(-50%);
transform: translateX(-50%) translateY(-50%);

Consider whether adjusting -webkit-transform is necessary to counteract the 50% positioning.
