Good afternoon,
First of all I thank you for your fabulous framework.
Need your help and I need a working example for ios6 where you can record video with data being captured while recording.
Eg record the acceleration data captured while recording the video, it would be possible?

I sincerely hope that you can help me on this issue and I'm doing a project for my project for my thesis and I need a working example.

Thanks and kind regards.

I'm not going to write your project for you, but I can say that you might look at how I set up my GPUImageHistogramGenerator to see how you might create a realtime plot using OpenGL ES and then overlay that on incoming video (as I do in the histogram example in the FilterShowcase). With some modifications, this could be made to do simple line plotting of incoming accelerometer data.

You could also look at using Core Plot to graph this, and then import that as a UI element, but your rendering performance will most likely suffer because of all of the Quartz drawing involved.
