  2. Stream Detection: Most modern streaming sites do not serve video as a single file. Instead, they use HLS (HTTP Live Streaming) or DASH (Dynamic Adaptive Streaming over HTTP). These technologies break video and audio into thousands of tiny file segments (chunks) that are reassembled by the player in real-time.
