Show HN: Automagically synchronize subtitles with video, in-browser clientside

Based, Automagically synchronize subtitles with video, in-browser clientside works in show hn launch.

Profile

Input a video and subtitle file, receive a synchronized output, no need to mess with python environments are dependencies (which historically was a challenge for ffsubsync users). This works thanks to ffmpeg.wasm to extract audio + pyodide for all the python dependencies (including one I had to compile to webassembly myself in order to get voice audio detection, since all I had was the webrtc-vad source code!)

Its activity falls under show hn launch; the profile below is assembled from public directory data.

Directory data places it at the Show HN launch stage.
