DevTools Media Panel

DevTools panel that displays technical details about media elements and webrtc on the current page; intended primarily for web developers to understand media playback issues on their sites, and for users to provide more informative bug reports.

The DevTools Media Panel is a powerful Chrome extension that integrates seamlessly into your browser's Developer Tools, adding a dedicated panel named "Media-Webrtc". Designed primarily for web developers and advanced users, this tool provides comprehensive technical details about media elements and WebRTC connections on the current page.

Within the media tab, users can inspect each video element’s playback state, including various diagnostic parameters that help identify issues with media playback. The WebRTC tab presents detailed information about each PeerConnection and GetUserMedia (GUM) instance, making it easier to troubleshoot streaming and peer-to-peer communication problems. This extension empowers developers to better understand and resolve media-related challenges on their websites, while users can supply more insightful bug reports.
