    HLS vs WebRTC — when to choose?
    HLS — 8–12s latency, ~5× more concurrent viewers, lower CPU. Best when real-time interaction is not required.
    WebRTC — ~300ms latency, real-time interaction, but higher CPU & more sensitive to network conditions.

    How Does It Work?

    STEP 01
    Load Stream

    Paste your M3U8 URL

    Enter any publicly accessible HLS playlist URL and click Load Stream

    STEP 02

    Allow browser access

    Grant camera & microphone permissions when the browser prompts you

    STEP 03
    Stream is Live

    Stream plays in player

    hls.js loads the stream — ABR, bitrate & buffer metrics update live

    Frequently Asked Questions

    An HLS/M3U8 player is a browser-based video player that reads HTTP Live Streaming playlist files ending in .m3u8. The playlist references segmented video files that the player fetches sequentially over HTTP, enabling adaptive bitrate playback across different devices and connection speeds without requiring plugins or additional software.
    Paste any publicly accessible M3U8 URL into the Stream URL field and click Load Stream. The player connects using hls.js, parses the manifest, and begins playback. The diagnostics bar updates bitrate, quality level, buffer length, and dropped frames in real time as the stream plays.
    HLS delivers 8–12 seconds of standard latency due to its segment-based buffering pipeline. WebRTC delivers approximately 300ms latency using direct UDP transport with no segment buffering. The HLS player on this page demonstrates standard HLS latency — the WebRTC vs HLS demo page shows both protocols playing the same stream simultaneously so the gap is directly visible.
    Ant Media Server supports full client-side ABR for HLS delivery. The player fetches a master playlist listing all available quality renditions, then automatically selects the appropriate bitrate tier based on the viewer's current bandwidth. The quality selector in this player lets you override automatic selection and force a specific resolution manually.
