React Video Streaming Application Prototype

Current Features:

Geolocation
Front- and rear-facing cameras on mobile
Live drawing canvas overlay with colored swatches in the left sidebar. Swipe the screen or click-and-drag to see it in action. The trash icon clears the canvas.

Feature Pipeline:

Map overlay. This is a work in progress. Click the map icon to pull up the overlay. Map has not been fully implemented yet.
User profile setup
Sharing of geolocation (available on mobile devices), azimuth, and streaming status
Stream recording and data storage
Stream sharing

Mobile Screenshot:

The concept is a live video streaming with a drawing interface and map overlay. HTML5 capabilities are used to track GeoLocation and device orientation. On the development roadmap are the following features:

Toggle full-screen mode
Logging in as new or existing user
User profile setup
Tracking of user activity, i.e., user’s logged-in status, whether the user is streaming live video, user’s location (if logged in)
Map overlay should display logged in users along with their streaming status, device orientations and camera facing directions; icons should appear on map, color-coded by streaming status, with icons rotated to reflect real direction based on compass’ true north
Functionality should be accomplished entirely through HTML5
Native application development (iOS, Android, etc.)
Recording of user’s drawing activity as SVG, possibly with configurable frame rate
Screen recording functionality; this should include recording of live media stream as well as user’s drawing activity on separate recorded tracks
Cloud storage of recorded media tracks with administrative interface for managing user’s media
vHyve Studio module to manage stored media inclusive of post-production tools
