TCPiMap

• Video Presentation

Based on

• openFrameworks, C++ Framework
• ofxOMXPlayer, OpenMax Video Player
• ofxGLWarper, Quad Warping Addon
• CTL, a Pure-Data cue list

This is a video mapper running on Raspberry Pi, and controlled over network from a distant computer. An almost unlimited number of Raspberry Pis can be controlled at the same time, and everything can be scripted.

Each Pi is attached to a projector with a small hdmi cable, and wired to the network, or connected to a WiFi router. The medias are hosted on the Pi and can be transfered via network.

• Each be controlled, automated and scripted:

  • Purr-data patch to make all kind of cue scripting with very powerful features

• Videos are loaded directly on sd-cards:

  • No video cables required all over the place, only Ethernet cables (or WiFi).
  • autonomous playing (5w consumption) for installations purposes
