What are the steps to preview a video using AngularJS?

I have a unique feature in my Angular.js application that allows users to upload various types of files, including documents, images, and videos. While I have successfully implemented the functionality to upload any type of file, I am now looking to find a way to preview and play videos within AngularJS. The HTML code below showcases how I currently handle viewing PDFs and images, which is functioning as expected. However, I am seeking guidance on how to enable video previews and playback.

HTML for Viewing Images and PDFs

<div class="col-md-12 text-center top30 nopadding">
    <div class="col-md-12 pull-right">
        <a target="_self" href="{$ main.record.preview.preview $}" 
           download="{$ main.record.preview.file $}">
            <button class="btn btn-primary pull-right inline-block">
                <i class="fas fa-download"></i> Download 
            </button>
        </a>
    </div> 
    <div class="col-md-12 pull-right top10">
        <p class="inline-block pull-right">{$ main.record.preview.file $}</p>
    </div>      
</div>

<div class="col-md-12 top10">
    <img ng-class="{'hidden' : main.record.preview.type != 'image'}" style="width: 100%" 
         class="img" src="{$ main.record.preview.preview $}">
    <object ng-class="{'hidden' : main.record.preview.type != 'pdf'}" 
            ng-show="(main.record.preview.preview != undefined || main.record.preview.preview != '') && main.record.preview.type == 'pdf" 
            data="{$ main.record.preview.preview | trusted $}" 
            style="width: 100%;height: 800px"  
            data="{$ main.record.preview.preview | trusted $}" type="application/pdf">
        <embed src="{$ main.record.preview.preview | trusted $}" type="application/pdf" />
    </object>

    <div ng-show="main.record.preview.type == 'others'" 
         class="col-md-12 text-center text-default no-preview" >
        <p><i class="far fa-times-circle"></i> No Preview Available</p>
    </div>
</div>

Answer №1

If you're looking to have a sneak peek of your video show up when users click a preview button or hover over it, there are some simple steps you can take to make this happen.

While there may not be an out-of-the-box solution for this in frameworks, some video hosting sites might offer this feature as part of their service.

The process involves creating a preview image or poster image from the video, which serves as a still image that is shown before clicking on the preview or hovering over the video. Additionally, a shorter preview video extracted from the original and encoded at a lower bitrate and resolution is created. This preview video can be hosted on your website and played when the user interacts with the preview image.

  • When users want to watch the full video, they can simply click a play button or the preview itself, and the site will switch to stream the full video from wherever it is hosted.
