I am using eclipse and proclipsing for a project in processing 2.0. I select the "video" library when I set up the project, and then proceed to use very basic example code to play a movie. I can play the movie loop example perfectly well in the Processing app, but in eclipse get the following stack trace:

Neither running the app in 32 bit mode, nor importing the GStreamer library independently, fixes things. If anyone can help, I would very much appreciate it. I had assumed movie playback would be straightforward as it is in Processing 1.5, and this is driving me crazy!

I'm currently running an app where I have an SVG map of the US.  I center the map with a translate(width/2, height/2) at the beginning of every draw loop.

I then track a "zoom" variable that increments and decrements with right and left mouse clicks, respectively.  This variable is fed to the scale function, and results in the map being zoomed via clicking.

However, I would like the zoom to be centered around the click of the last mouse point.  This is easy to do on a single click, as you just modify the translate arguments.  However, as the clicks continue, and the zoom becomes higher, it becomes difficult to calculate the "layered" zooms that all involve a centered click at different levels of scale. 

Does anyone have any insight on how to zoom on a clicked point, but keep re-centering on successive zooms?  I think this is less of a coding question, and more of a math question as to how one can track and center on the click locations at multiple zoom levels.

Would love to hear your thoughts.
