Here we will decode an Ogg Theora file streaming from the internet onto a plane surface scripted in Unity 3d.
The fastest method to do this as of writing is to look here and then attach this to the camera in a new unity 3d scene.
The Unity docs do not seem to show a C# source example, so in full Blue Peter (UK) style: Here is one I made earlier.
// Name : WWWVideoTexture (Unity 3d)
// Author : Divide To Infinity
// Version : V1.0
// Copyright : GNU GPL v2
// Description : C# Monobehaviour Script for Decoding Video Streams to Texture
public class WWWVideoTexture : MonoBehaviour
public string url = "http://playground.html5rocks.com/samples/html5_misc/chrome_japan.ogv";
WWW www = new WWW(url);
MovieTexture movieTexture = www.movie;
yield return null;
GUITexture gt = GetComponent();
gt.texture = movieTexture;
transform.localScale = new Vector3(0, 0, 0);
transform.position = new Vector3(0.1f, 0.25f, 0);
gt.pixelInset = new Rect(0, 0, movieTexture.width / 2, movieTexture.height / 2);
AudioSource aud = GetComponent();
aud.clip = movieTexture.audioClip;

Daksyba are a collective of audio and visual artists from a range
of creative disciplines, combining voice, percussion, strings, didgeridoo, digital sound and video.
“Art is mostly experienced as the aftermath of the creative process. It may be composed, rehearsed, performed or recorded and as such it is but a reflection of that process. Improvisation, as a premise, invites the artist and spectator to share a moment and witness art as a unique event as it emerges, truly in the here and now” – Illi Adato, Artistic Director, Art of the Moment.
Art of The Moment is a 2 day event integrating music, dance and visual arts in fresh new ways and re-examining the relationship between the different medium. It is a celebration of art created in the glorious uncertainty of the here and now, deep in the heart of spontaneous composition.
The festival will feature contributions from the likes of the amazing Oren Marshall (collaborations include Radiohead and Charlie Haden), Maggie Nicols, Anton Mobin, Phil Minton, The Irrepressibles, Matt Black (Ninja Tune, Coldcut), h2dance, Mixmaster Morris and many other leading artists in the field.
It takes place in one of London’s most fascinating art hubs, The Albert in Queen’s Park, and is open to everyone to come and enjoy, explore, experience and get involved.

MIDI Maximilian Scope Synth
This program requires the use of a MIDI controller to work – compiled example can be found in the /bin folder. This requires .NET framework 4 (not 4.5) and Visual Studio 2010 libraries to be installed if you are on Windows. The program features a scope adapted from the ofxMaxim example in OpenFrameWorks and comprises of a mono legato triggering synthesizer. Filter cutoff is controlled by momentary on velocity switching and oscillator gate is permanantely on due to having no ADSR and quick and dirty MIDI triggering logic.
This program fills an array with random values based on the screen height and iterates through sending the value to a sawtooth oscillator. This implements switch cases – pressing 1 will Bubblesort the array to give a saw glissandi – while pressing 2 will randomise the array data again.
This was intended to be the main project however due to the nature of how the Emotiv headset examples are organised, I was sadly unable to suitably map the functionality to the way that OpenFrameWorks operates – this code is provided only as a means to see where I am with implementing this. The majority of the code is cut up examples from the emotiv library mixed in with MIDI and Maximilian.
I have modified this code slightly from the original supplied by the ofxMidi author Chris O’Shea. I added to the example by listing all MIDI ports by pressing ‘l’ for list and changing midi ports on the fly using a switch case with numeric input for easy testing.
This is a simple test to see how well the Quicktime library works on windows 7 x64, I simply looked into the API and set up a few cases by pressing 1,2,3 and 4 – video play speed, pause and play direction. Sadly this not work with my original video which had a higher bandwidth (had an error code -50 – I could not find the solution anywhere) so this uses the standard ‘fingers’ video.
Unzip these archives into your ‘myApps’ directory in OpenFrameworks.

If you are on Windows, you can execute the debug app in the ‘bin’ folder provided you have all the correct Microsoft C++ Redistributable installed.
Precomplied versions of all projects can be found in their associated /bin folder for easy testing.
