## What it is
A JavaScript/TypeScript library that plays MPEG2-TS and FLV streams in HTML5 browsers by transmuxing them into fMP4 segments fed through Media Source Extensions. It is optimized for low-latency live playback such as DVB/ISDB TV or surveillance cameras, and is based on flv.js.

## Use cases
- play low-latency MPEG-TS live streams in the browser
- play HTTP-FLV or WebSocket-FLV streams with sub-second latency
- playback of surveillance camera streams in a web page
- play .m2ts files (BDAV/BDMV) in the browser
- support HEVC or AV1 over MPEG-TS/FLV playback
- extract ARIB B24 subtitles or timed ID3 metadata from TS streams

## When to choose
- you need sub-second latency live streaming in browsers via MSE
- your source is MPEG2-TS or FLV over HTTP(S) or WebSocket
- you need HEVC/AV1 or enhanced-RTMP codec support in the browser

## When to avoid
- you need VOD with adaptive bitrate (use hls.js or dash.js)
- your target browsers lack MSE/ManagedMediaSource support
- you need DRM-protected content playback

## Facets
- artifact type: library
- maturity: active
- function: video-processing, streaming, serialization
- domain: media, web-development
- platform: browser, cross-platform
- tags: mpegts, flv, mse, html5-video, live-streaming, low-latency, transmuxer, hevc, av1, video
