Mix Codex::The Ultimate Hybrid Guitar Rig

INTRODUCTION

Probably want to talk about splitting a DI Signal into the DAW to have the re-amp tone and also recording the amped signal with two notes hardware to power soak and capture the coloured tone.

Coders Codex::Command Line Arguments Example for JUCE C++

INTRODUCTION

I base this article around the need to pass command line parameters to a running program. Please note this does not seem to work with Windows yet (working in Linux and OSX not tested).

DISCUSSION

The idea is to use a set of command line parameters to execute a set of built in software tests between two or more instances of a given software and then automatically generate unit test reports. The whole thing can be automated via the sequencing of various tests in a bash script or batch file.

Video Codex::Panasonic Lumix DMC-GF6 Quick Review

INTRODUCTION

Here is a quick review of the Panasonic Lumix DMC-GF6 Digital Camera (Micro 4/3 Sensor). First up is the unboxing video below which is also filmed with another Panasonic Lumix DMC-GF6 in auto-focus.


DISCUSSION

The range and versatility of this camera is truly astounding with the standard kit lens. Even for a novice such as myself I was able to get some brilliant creative shots in low light using the manual settings. This camera really does come to life when using the manual settings and although they are not as easy to tweak and control as Canon DSLR’s, they certainly do give a wide palette of variation.

FINDINGS

The maximum video recording time for the AVCHD and MP4 mode is 29 minutes and 59 seconds as expected due to EU regulations imposed on all digital cameras. See here for more information on why the 30 minute recording time limit is placed on digital cameras. If you require more recording time onboard, look at the Blackmagic range of cinema cameras. As expected they would have paid the additional EU taxes on being able to record for longer times. The time limit is imposed via red tape and is a legal president which stops manufacturers of cameras which limit the recording time, otherwise this is declared as being a video camera. There is also a time out for standby and a menu will display on the HDMI output when left unattended for a period of time. This is applied to many cameras and consumer camcorders to stop live streamers from using anything other than professional grade video cameras for this purpose. For users of Canon DSLR’s there is discussion of extending the recording time via Magic Lantern here. The recording of RAW Video is not possible, this is only available on Canon DSLR with Magic Lantern and Black Magic design Cameras.

Coders Codex::Decoding Video Streams to Textures in Unity 3d

INTRODUCTION

Here we will decode an Ogg Theora file streaming from the internet onto a plane surface scripted in Unity 3d.

DISCUSSION

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.

FINDINGS

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.

Divide To Infinity – Advanced Audiovisual Processing with OpenFrameWorks C++ Libraries

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.

Bubblesort:

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.

EEG Maximilian:

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.

MIDI Example:

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.

videoPlayerTestModified:

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.

The link to all of the above source code and materials can be found here.

Unzip these archives into your ‘myApps’ directory in OpenFrameworks.

For more info on OpenFrameWorks and creative coding as an art form, go here.

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.
