◆  TravaLive: a browser extension to watch lives in sync  ◆

Original post in Portuguese: /pt/posts/travalive/. This English version is machine translated.

During Brazil's last match, which ended in a sad draw, I noticed a downside of watching on YouTube instead of TV: beyond the delay relative to people reacting out on the street, my friends and I were out of sync (I could hear some of them react before the play happened for me). So I decided to build something to tune the live in like it was a TV.

It turned out I can use YouTube's own player, which carries a value for how far the stream is delayed. After spending a few hours building a POC, I got the code working in roughly 100 lines. The extension is called TravaLive and it will be available for Chrome (and its many derivatives) and Firefox as soon as the respective stores approve it. TravaLive uses no personal data and has minimal permissions that let it control the videos on YouTube; as a way to verify that, I left the code public on GitHub: github.com/loadez/travalive.

Once one of the stores approves it, I will write another post explaining a bit more about how to install it and how it works. For now, that is it.
