Public Signal Video Feed
Public Signal Video Feed is a YouTube playlist feed plugin for WordPress. It provides a live block editor preview, a lightweight shortcode, transient-based API caching, responsive grid and list layouts, and a keyboard-friendly modal player.
Features include:
- Video Feed block with a non-interactive live editor preview.
- YouTube playlist feed shortcode.
- Grid and list layouts.
- Optional video limit and channel display controls.
- Cached API responses to reduce quota usage.
- Frontend fallback link and playlist embed when API data is unavailable.
- Keyboard-friendly modal playback with focus management.
- Global visual defaults with optional per-block color overrides.
This plugin requires a YouTube Data API v3 key supplied by the site administrator.
External Services
Public Signal Video Feed relies on services provided by Google and YouTube to retrieve and display playlist content.
When an uncached feed or block editor preview is rendered, the site sends the configured YouTube Data API key, the playlist identifier, and a pagination token when needed to the YouTube Data API endpoint at https://www.googleapis.com/youtube/v3/playlistItems. The API response is normalized and stored temporarily in WordPress transients for the configured cache duration.
Playlist thumbnail images load in a visitor’s browser from the YouTube or Google-hosted image URLs returned by the API. The normal YouTube iframe player loads after a visitor selects a video. If API playlist data is unavailable, a fallback YouTube playlist iframe may load when the page loads. These browser requests can transmit technical information such as the visitor’s IP address, browser user agent, referrer, and cookies to Google or YouTube.
