Bitford: A Streaming BitTorrent Client for Chrome

on YouTube ↗26m

" summary

Bitford implements the BitTorrent wire protocol in JavaScript inside a Chrome Packaged App to fetch .torrent files and begin playback almost immediately over TCP client sockets. It stores downloaded pieces using the browser fileSystem API and IndexedDB, performs background SHA-1 hashing of 256 KB pieces, and feeds verified blocks into the HTML5 MediaSource Extensions buffer while managing flow control around Chrome’s numeric socket IDs; the demo works, with remaining gaps due to Chrome API limits (e.g., no server sockets).
