How VideoLab Works

Three steps to test and debug any video stream

Paste a URL or Upload a File

Drop a link or drag a file right into the player. We'll detect the format and start loading the video.

Watch Diagnostics Update Live

As the video plays, the debug panel tracks the connection status, resolution, bitrate, and network events as they happen.

Share or Export Your Logs

Generate a shareable URL to let someone else see your exact test environment, or download a JSON debug log to review later.

Testing Live Streams

Live streams are continuously updated playlists. VideoLab's HLS player polls the manifest for new segments and shows each segment load in the network log. This helps diagnose whether buffering is caused by slow segment generation or slow CDN delivery.
