What it does
You can upload videos and assign images to them, and whenever you scan the photo with your phone's camera, it plays the video on top of that photo. Sending a video post card with only one image, how cool is that?
How I built it
We used Ionic for UI of the application and Vuforia for the back-end processes (Open-source packages)
Challenges I ran into
Streaming videos from the cloud, uploading videos, syncing the back-end with the UI, Playing dynamic videos, assigning each video to one unique image
