TIFF files from pix_buffer (and others?) missing some "standard" tags?
by B. Bogart 06 Aug '10

06 Aug '10

Hey all, I've had trouble loading some TIFs generated in pd/Gem in PIL (python imaging). I asked on the list and it seems PIL expects some particular TIF tags being set in order to recognize the image. I think it can only be an improvement to add these tags so that tifs generated in pd/Gem can be loaded by as many applications as possible. The attachment contains the specific tags. Thanks, B. Bogart

model UV...
by sebastian pirch 07 Sep '09

hi IOhannes! in 1st place, THANKS for implementing this feature ;) you realy make me happy. i installed your experimental win build and it works great, when i add the gem directory to file/paths. only when i do so, pd crashes when i load a .mov using pix_film or pix_movie. when i remove the Gem path from file/paths again, pix_film and pix_movie work fine again, - but no more uv coordinates...is it a bug? or am i doing something wrong? im using pd extended 0.40.3 on winXP thanks for doing all this sebastian IOhannes m zmoelnig wrote: > hi. > > i have just added UV-texture support to [model]. > > now, UV-texcoords are automatically applied if present in the model > (with a fallback to the old-standard "linear" texmaps); you can manually > select UV-tex via [texture 2( (uÃ¤h) > > > > please test whether this change has broken something with the other > (linear/spheremap) texturing, esp. if you have additionally used > [pix_coordinates] > > fgmSDR > IOhannes -- www.3rd-eye.at Psssst!

pix_filmQT vs pix_filmDarwin on OSX?
by IOhannes m zmoelnig 24 Feb '09

24 Feb '09

what's the difference between pix_filmQT and pix_filmDarwin on OSX? it seems like pix_filmQT cannot open movie-files (here), wherease pix_filmDarwin works just fine. can therefore pix_filmQT be removed entirely? (on w32, pix_film+filmQT is used successfully anyhow; i think pix_filmQT originally came from the w32 implementation) mfg.adsfr IOhannes

Bogart (bbogart) Assigned to: Nobody/Anonymous (nobody) Summary: Objects with few parameters should be settable by argument. Initial Comment: For example pix_crop has 4 inlets, but those values can't be set by arguments, according to the help-file. It would be ideal to forgo the loadbang-message construction in these cases. Same goes for "sphere" were you can't set the number of faces via argument. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=507082&aid=2549887&group_…

I get are you using the Pd-extended builds or did you build Gem yourself? afaik, Pd-extended does not link against libv4l, thus you do not enjoy it's pleasures. simply do % ldd Gem.pd_linux | grep -i v4l > > VDIOCGCHAN: Invalid argument > > I could not find libv4l in the ubuntu repos but have libv4l-0 installed. this is the same. it is just a naming issue, which you will find often in Debian/Ubuntu, supposedly to get around the issue of API-changes (and being able to install several different API-versions of a single library at the same time) if you compile Gem yourself, you will also want to install the development-headers of libv4l (libv4l-dev) before running configure. finally: afaik, you can force an application built without libv4l to use it by employing some pre-linker magic. ("LD_PRELOAD_LIB=/usr/lib/libv4l.so pd -lib Gem" or the like) - please see the README.txt that comes with libv4l for instructions. fgmasdr IOhannes

pix_movie crashing on OS X 10.4 (Pd extended 0.41.4 autobuild 20090117) Intel
by John Harrison 28 Jan '09

28 Jan '09

pix_movie is crashing as soon as a Gem window is rendered. The pix_movie help patch crashes too. Even this very simple attached patch will segfault Pd when |create, 1( is clicked on. I tried various tricks I could think of (opening the movie file before rendering etc.) but couldn't get anything to prevent the segfault. Pd extended 0.41.4 autobuild 20090117 (intel) GEM: ver: 0.92.CVS GEM: compiled: Jan 17 2009 -John

random lockups on Intrepid when Gem window open
by John Harrison 26 Jan '09

26 Jan '09

I mentioned this problem about a month ago on the Pd list but it was cluttered with a bunch of other issues and may not have been explained well. I have seen 3 different machines completely lock up between 10 seconds and forever when a Gem window is open. All that is required is that the Gem window is open. Redsquare, for example, will trigger the symptom if the gem window on that patch is opened. The lock up doesn't happen immediately but happens sporadically. It also happens continually. During the lockup, even the mouse won't move and the screen is not updated. After the lockup, suddenly the machine will be OK --- until it locks up again a few minutes later. Other opengl apps don't lock up. For example, I can run glxgears all day with no problems. The machines all had the following in common: - ubuntu Intrepid (1 had 64 bit one had 32 bit) - nVidia proprietary driver that comes with Intrepid (I tried 3 different versions of the driver. Same symptoms) - AMD branded processor - Gnome/metacity or Gnome/compiz One of the machines had 64 bit Hardy and ran fine. Then when changed to 32 bit Intrepid the symptoms came up. One is a laptop, the other two are desktops. Does anybody else have Intrepid/nVidia/Gnome? It would be interesting to see if he/she is also having the same problem.
