DualPlayer
A browser-based movie player that plays two audio tracks from the same film on different devices at the same time, so one viewer can listen to the original language in headphones while another hears the dub on speakers. It requires no installation or account, and the movie file never leaves the user's computer.
What it addresses
The author is learning English and wanted to watch movies in the original language with his girlfriend, who isn't learning English and didn't want to watch that way; no existing tool let two people watch one movie with different audio tracks, so he built one.
