Video Stream Test – Test Any Live or VOD Stream
Test whether your live stream or VOD source is working correctly. Supports HLS, DASH, and MP4 streams. The debug panel measures startup time, segment load events, and buffering behavior.
How VideoLab Works
Three steps to test and debug any video stream
Paste a URL or Upload a File
Enter any MP4, M3U8, MPD, YouTube, or Vimeo URL — or drag & drop a local video file directly into the player.
Hit Play & Watch Diagnostics Update Live
The player starts streaming instantly. The debug panel tracks connection status, resolution, bitrate, codec, and every network event in real time.
Share or Export Your Debug Log
Generate a shareable URL to reproduce the exact test, or export a full JSON debug log with timestamps, errors, and stream info.
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.
