gem on mac intel
by cyrille henry 18 Feb '06

18 Feb '06

hello, a friend of mine and me are tring to have pd and Gem running on a iMac Core Duo intel. there is still an endianness problem with portaudio, but after forcing endianness, pd compile and sound is ok. most of externals compiles. about Gem : there is problems with a few pix objects : we have just removed them for now. but we still have a problem with the last part of the compilation (-ie the bindings with pd). it should be simple to fix it for someone who know... attachement is the ./configure and the make log. Adrien can only use the Core Duo system until wednesday. ideas are very welcome. Thanks Cyrille

Guassian Blur pixel shader?
by B. Bogart 17 Feb '06

17 Feb '06

Hey all, Now that I have Gem actually compiling again on my linux machine I wonder if my dream of a realtime blur could be a reality with pixelshaders. :) Anyhow know of some extreme blurring I can apply as a pixelshader to a texture loaded in gem? Thanks Johannes for the help with the Gem compile. I remember why I needed to recompile it, to test the v4l2 support. I'll do that today and report back. .b.

V4L2
by B. Bogart 16 Feb '06

16 Feb '06

Hi Johannes, So now I would very much like to be able to use two of my video capture devices to work in Gem. Right now only the wintv works fine, though a little buggy, but I can't get anything out of the cx878 boards. xawtv works on both cards equally. I have a hunch this may be due to an imcompatibility with the v4l wrapper v4l_compat around v4l2 drivers. (I'm using 2.6.13-ck5) How about pix_video using v4l2 proper rather than v4l? .b..

strings are 1 of my big weakness's
by james tittle 16 Feb '06

16 Feb '06

...I've been trying to get [pix_freeframe] to work, but no luck: I keep get bad memory accesses! I just don't know much in the way of unix string tricks :-( Here's what I was trying: char *extension= #ifdef __WIN32__ ".dll"; #elif defined __APPLE__ ".frf"; #else ".so"; #endif int fd=-1; // Hoops to jump thru for apple's bundle structure :-( #ifdef __APPLE__ strcat(extension, "/"); strcat(extension, pluginname); #endif if ((fd=open_via_path(canvas_getdir(getCanvas())->s_name, pluginname, extension, buf2, &bufptr, MAXPDSTRING, 1))>=0){ ...my first thought is just to see if we can append ".frf/ nameOfPlugin", which would be a symbolic link to the more deeply buried binary in the bundle...if that works, that'd be fine, but if not, we could try appending ".frf/Versions/A/nameOfPlugin", which is the explicit bundle location... help? jamie

Hi Chris, Is there anyway I can tell quicktime to play the audio for my pix_movie sound through the external edirol device, rather than built-in audio? Thanks! .b.

pix_fiducialtrack help?
by james tittle 13 Feb '06

13 Feb '06

...looking thru additions I haven't kept up with as much as I should, I'm trying to understand how this object works ;-) The data file loads, but in the help file I don't get any output from the ID, x, y, or angle...? Also, there's a second inlet that is undocumented in the object: is it just for another way to open a file, or something else? The code seems to mention a necessary vector... jamie

pix_freeframe and m_instance
by james tittle 08 Feb '06

08 Feb '06

...I'm currently trying to get [pix_freeframe] working again on osx (the plugin structure was changed for the freeframe 1.0 spec)...I've got the new bundle loading code working, but it's crashing when trying to actually processImage()...the most obvious problem in gdb is that the height and width don't seem to be passed to the plugin, and I'm having a hard time finding where this is filled out...this is working on linux, right? jamie
