  • Video-Hub-App

    Official repository for Video Hub App

    • I ended up using a QR code in my (Electron) app: the app runs a server, and you take a photo of the QR code on your phone to open the localhost (accessible only over WiFi). The app lets you browse videos you have on your computer through your phone, and when you click on the video image, the video plays on your computer from the frame you clicked on. It turns your phone into a "remote". Cheers: https://videohubapp.com/

  • qr.js

    qr.js: QR code generator in pure Javascript (2011)

    • I probably know this only because back in time I wrote a QR code generator in JavaScript [1] which was also one of such libraries reviewed by Nayuki [2], and as I haven't actually implemented a decoder my knowledge stops there. Sorry :-)
