🔧 Technical Details

What you're seeing: This demonstrates our proposed HLS video podcast standard using the podcast:alternateEnclosure tag. The RSS feed contains both traditional audio and HLS video streams, allowing podcast apps to offer video when supported while maintaining audio-first compatibility.

HLS Benefits: Adaptive bitrate streaming, no large file downloads, automatic quality adjustment based on connection speed.

Browser Support: Safari (native), Chrome/Firefox (via HLS.js), most modern video players.

Sample XML: In this example the alternateEnclosure sits underneath the legacy audio enclosure. This means that podcast apps will default to the audio version for compatibility, while video-capable apps can detect and use the HLS stream for enhanced viewing experiences.
