At Demuxed 2025, I presented streamrr, a small Rust tool that records an HLS stream (playlists, segments and all) and replays it later, exactly as it happened. Watch the talk below, or read on to find out how it works under the hood.

At Demuxed 2023, I came back with a sequel: I took baby’s first HTML5 <video> element and taught it to play video (and audio) backwards, frame by frame. Watch the talk below, or read on to find out how it works.

At Demuxed 2022, I gave a talk about rebuilding the HTML5 <video> element from scratch, handling buffering, decoding and rendering myself with Custom Elements and WebCodecs. Watch the talk below, or read on to find out why (and how) I built this crazy contraption.
