Struggling with resizing a webcam feed to fit the dimensions of the iframe container?

I'm facing a challenge embedding a camera feed into a webpage that needs to display manual focus and servo controls. The issue lies in the content scaling within the iframe.

Even though the iframe boundary resizes according to the window's width, the embedded page (an mjpeg page created by an application) is not scaling correctly.

Below is the code snippet:

<!DOCTYPE html>
<html lang="en" >
  <head>
    <meta charset="UTF-8">
    <title>Ustreamer Webcam</title>
    <style>
      .icontainer {
        border: 1px solid red;
        position: relative;
        padding-bottom: 100%; /* set the aspect ratio here as (height / width) * 100% */
        height: 0;
        max-width: 100%;
      }

      .icontainer iframe {
        border: 1px solid blue;
        position: absolute;
        top: 0;
        left: 0;
        width: 100%;
        height: 100%;
      }
    </style>
  </head>

  <body>
    <div class='icontainer'>
      <iframe src='http://abc.def.com:5001/webcam/?action=stream' allowfullscreen></iframe>
   </div>
  </body>
</html>

Is there a way to resolve this issue? Unfortunately, I have limited control over the source page unless absolutely necessary which may bring about additional complications.

Answer №1

The link you're integrating leads to an image data stream, which the browser will encapsulate in a basic HTML structure along with an img element. An image typically doesn't automatically adjust its size - and because the iframe content is from a different source, customizing its styling can be challenging.

Consider using an img tag instead of an iframe from the start to embed the image on your page directly, allowing you to style it as needed.
