Latest YouTube Video Embedder (RSS Version)

Contributors: merlynx Plugin Name: Latest YouTube Video Embedder Tags: youtube, youtube embed, latest video, playlist, rss, shortcode Requires at least: 4.5 Tested up to: 6.8 Stable tag: 1.4 License: GPLv3 or later

Embed the latest YouTube video from a channel or playlist using a WordPress shortcode — no API key required.

Description

Latest YouTube Video Embedder retrieves the newest public YouTube video without requiring a YouTube Data API key.

The plugin tries YouTube's public RSS feed first. If YouTube's RSS service returns an error, it falls back to the public channel /videos page or playlist page and extracts the newest video ID from YouTube's own rendered page data. The most recent successful video ID is also retained as a last-known-good fallback so a temporary YouTube outage does not blank an existing embed.

Configure your default channel ID and/or playlist ID via Dashboard > Settings > Latest YouTube Video. Use the shortcode [latest_youtube_video] anywhere in posts, pages, or widgets.

Installation

1. Download the plugin ZIP file from GitHub Releases.
2. In your WordPress admin panel, navigate to Plugins → Add New.
3. Click Upload Plugin and select the downloaded ZIP file.

Usage

1. Go to Settings → Latest YouTube Video in your WordPress dashboard.
2. Enter your default channel ID and/or playlist ID.

4. Use shortcode attributes to pull from a playlist or override the ID.

FAQ

Do I need a YouTube API key?

No. The plugin uses public YouTube RSS and public YouTube web pages. It does not call the authenticated YouTube Data API.

What happens if YouTube RSS is unavailable?

The plugin tries the corresponding public YouTube channel or playlist page. If that also fails and the plugin has previously retrieved a valid video for that source, it serves the last known good video instead.

How often does the plugin refresh?

A successful result is cached for one hour. The last known good video is stored separately and retained across transient expiration.

How do I get a channel or playlist ID?

• For channel ID: use YouTube's Copy channel ID option or the UC... value from the channel URL/source.
• For playlist ID: copy the part of the playlist URL after ?list=.
