Tips for Optimizing Video Content for Mobile Devices

Upon reviewing the first image, it is evident that the video is displaying correctly:

However, in the mobile version, the poster does not show up. Only a play button is visible. Moreover, even when the play button is clicked, nothing happens:

Is there a way to make the mobile version of the video resemble the desktop version? Ideally, I would like a poster image with a play button overlay, and when the play button is clicked, the video starts playing.

HTML

<video style="width:40%; display:block; margin:0 auto;" controls>
  <source src="/assets/fake-prince.m4v" type="video/mp4">
</video>

Answer №1

One way to display an image before a video plays is by using the poster property within the <video> tag. This can be done by specifying an Image file you want to show until the user hits play, as explained here.

<video style="width:40%; display:block; margin:0 auto;" poster="image-file-location-here" controls>
    <source src="/assets/fake-prince.m4v" type="video/mp4">
</video>

EDIT:

Instead of placing the <video> tag within the <p> tag, consider nesting it inside a <div class="blog-body"> element.

<div class="blog-body">
    <video style="width:40%; display:block; margin:0 auto;" controls="true">
        <source src="/assets/fake-prince.m4v" type="video/mp4">
    </video>
</div>

It's worth noting that using the <p> tag excessively may not be ideal, as it is intended for paragraphs. Consider using CSS properties like margin for spacing between elements instead for better performance.

Answer №2

In addition to what Blom said, the video on your website is in m4v format which can sometimes cause issues with playback, especially on Apple devices (I just downloaded and tested it on a Mac and initially it opened as a MetaData file instead of playing the video).

m4v is basically an mp4 video container with added features for iTunes to include copy protection.

Since you're not using copy protection in this case, simply changing the file extension from m4v to mp4 may allow it to play on most platforms (it worked on the Mac, for example).
