Re: photo booth using camera module and java?

During the Weekend, I'm a Wedding DJ and so see many Booths at the events I attend. Most take more time to set-up than my full rig (DMXed moving heads etc). The fee is fairly good for these booths, and so I'm hoping to develop my own system that can be bundled or dry-hired. This would be an excelle...

Re: Simple CCTV: Webcam > RPi > Composite Video?

That's exactly one of the things I want to do, except that the webcam I have planned on using is connected by ethernet, so I'll keep an eye on this thread! I've done a lot of work with both webcams and IP cameras under Linux, and I think that it's a bit easier to work with IP cameras (I'm assuming ...

Re: 2D Fluid a-la Plasma Ball via shaders?

And shadertoy has a Pi port: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=68&t=10246&p=117404 Awesome. I just spent a non-trivial amount of time trying to get a plasma shader working on the Pi. It works under Ubuntu, but the Pi version (using my admittedly crappy cross-platform SDL/OpenGL wrap...

Re: 2D Fluid a-la Plasma Ball via shaders?

This post may be helpful: http://stackoverflow.com/questions/6367818/opengl-es-2-0-plasma-shader . You can also look at the hello_triangle2 code for an example of how to use vertex and fragment shaders in your program. Based on how well hello_triangle2 runs, the Pi should have no problem running the...

Re: video capture using usb video capture device

I've had dismal results, (using easycap/kworld devices), getting them to work was fiddly and, from what I've seen thus far, the outcome will bear more resemblance to a classic nintendo gameboy than to a HD console... but technically, yes. Have you been able to use an easycap device? I've been using...

Re: libmikmod

I just now tried building with the 3.1.11 version of libmikmod, rather than the latest 3.2.2 version. I haven't yet tried playing any .MOD files with it yet, but it did build successfully without any of the errors that we both saw.

Re: libmikmod

I got the same result. I'm porting over one of my old games, which plays some .MOD files using SDL_Mixer, so I needed libmikmod. When I got the error message you saw, I assumed libtool wasn't installed. Just to be safe, I installed libtool, but I got the exact same error. Googling around, it seems a...

Re: Porting cmake

I can confirm that cmake builds under Raspian, at least from the basic terminal (without running X). It took a very long time to build, though.

Re: hello_triangle.c sample

I think I know how the terminate variable is being used here: it isn't. I was thrown by the fact that a mouse click ends the hello_triangle2 program, but I failed to see that a button press was being explicitly checked for, resulting in a break from the while loop. The "while (!terminate)" may as we...

Re: hello_triangle.c sample

The question remains: how is the variable terminate being set? Similar code appears in hello_triangle2.c. In both programs, there is no other appearance of the terminate variable. Is it being set by some outside process?
