(probably not;-)) + + +loading MPEG-movies crashes under Win32 +-------------- +POSTED 4/05/04 +-------------- +BUG: loading MPEG-movies (*.MPG) crashes pd +ANS: MPEG is not really supported under the Win32-version of Gem + however Gem tries to decode MPEGs via QuickTime which might crash (see below) + +loading AVI-movies does not work under Win32 +-------------- +POSTED 4/05/04 +-------------- +BUG: loading some AVI-movies with certain codecs does not work under Win2k and bigger. +ANS: Gem is (still) using a rather old API for decoding videos. + it might well be, that not all installed codecs are supported (e.g. Indeo-5) + + +have to destroy / create window to change lighting state in buffer == 1 +-------------- +POSTED 11/07/98 +-------------- +BUG: If you want to change the lighting when GEM is running in single + buffer mode, you have to destroy and then create the window. +ANS: hopefully we will drop single-buffer mode soon (enabling double-buffer feedback instead) (2004) + + +WinNT pix_video object +-------------- +POSTED 6/25/98 +------------- +BUG: The WinNT pix_video object has a lot of problems. It is not + very stable, tends to lock up the machine, etc. +ANS: don't have much problems with it. + daniel's directshow-support enables support for most newer (ieee1394,usb) cameras under win, + although the interface is somewhat different than on other OS's + (eg: set dimensions via pop-up menu,...) + + +splines are incorrect +-------------- +POSTED 6/25/98 +-------------- +BUG: In preventing the crasher in the spline object, I have introduced + another bug. Mainly, the end points don't get computed correctly. + + +Polygon doesn't tesselate (ie, polygons sometimes look strange) +-------------- +POSTED 5/19/97 +-------------- +BUG: Because the polygon object doesn't tesselate itself, + if it is concave, the behavior is undefined under OpenGL. + + +glxContext memory leak +-------------- +POSTED 5/18/97 +-------------- +BUG: The dummy glxContext doesn't ever get destroyed. Use a static object + to create and destroy it when the DSO is loaded/unloaded. + + +Indycam broken +-------------- +POSTED 5/1/97 +-------------- +BUG: The Indycam object doesn't seem to work. While getting the O2cam + up, I seem to have broken the Indycam object.

Should be okay now. + + +text object can't be found +-------------- +FIXED 2/21/98 +POSTED 5/1/97 +-------------- +BUG: Because the text is a special keyword and object inside of + pd, the text object cannot be found as a GEM object. The solution + is to rename it to something else. +ANS: I am using a cool library called gltt which will render true type + fonts in OpenGL. + + +Memory exception on WinNT +-------------- +FIXED 12/15/97 +POSTED 11/30/97 +-------------- +BUG: If you use pix_image, then there is a memory exception (ie, crash) when + you exit Pd.
