Lazy load videos and sticky control

This plugin improves page load times by lazy loading videos and displaying only the video preview image until playback begins. It now supports YouTube, Vimeo, Wistia, Dailymotion, JW Player, and self-hosted HTML5 videos, with built-in sticky video functionality that keeps videos visible at the top or bottom of the screen when users scroll away from the video viewport.

Features

• Lazy Load Videos: Reduce initial page load by showing only video thumbnail preview image first.
• Multiple Video Support: Add more than one video to a page. Only one video plays at a time, and the other video pauses automatically.
• Sticky Video: Keep videos visible as you scroll by pinning them to the top or bottom of the screen.
• Multi-Platform Support: Use YouTube, Vimeo, Wistia, Dailymotion, JW Player, or self-hosted HTML5 videos.
• Custom Styling: Adapt the video presentation with your own CSS.

Usage

Method 1: Using the Classic Editor (WP Editor)

1. Generate Shortcode in WP Editor:

   • Open the post/page where you want to add your video.
   • In the WordPress editor, click on the LLVASC icon. This will open a popup window.
   • In the popup, add your video ID. For YouTube, Vimeo, Wistia, Dailymotion, and JW Player, use only the video ID, not the full URL.
   • After entering the video ID, click “Ok”. This generates and inserts a shortcode into your content.

2. Shortcode Format:

   • The shortcode added to your content will look like this:
     [lazy-load-videos-and-sticky-control type=”youtube” id=”iXGoAj7IEys”]
   • Example shortcodes:
     [lazy-load-videos-and-sticky-control type=”vimeo” id=”76979871″]
     [lazy-load-videos-and-sticky-control type=”wistia” id=”26sk4lmiix”]
     [lazy-load-videos-and-sticky-control type=”dailymotion” id=”x75iqs7″]
     [lazy-load-videos-and-sticky-control type=”jwplayer” id=”hWF9vG66″]
     [lazy-load-videos-and-sticky-control type=”html5″ url=”YOUR_VIDEO_URL”]

3. Save/Update:

   • Save or update your post/page to apply the changes.

4. Preview and Customize:

   • Preview your page to see the embedded video.
   • If you need to adjust the styling, you can add custom CSS in the General tab of the plugin settings.

Method 2: Using Gutenberg Block

1. Add a Block:

   • Open the post/page where you want to add your video using the Gutenberg editor.
   • Click on the “+” icon to add a new block.

2. Select the LLVASC Block:

   • Search for the “LLVASC” block in the block library.
   • Add this block to your content.

3. Enter YouTube Video ID:

   • In the LLVASC block settings, select your video platform and enter the matching video ID. For HTML5, use the media picker to choose the video file.

4. Save/Update:

   • Save or update your post/page to apply the changes.

5. Preview and Customize:

   • Preview your page to see the embedded video.
