gem bugs on OSX
by ben＠ekran.org 14 Aug '03

Hey all, A stable release would be great. Currently up in the air are chances for Matt and I to teach pd/gem stuff at a college and university here. anyhow I only have very sporatic access to a mac nowadays, but I have noticed some pretty significant bugs. I wish I could send an example patch. yesterday we were using the gem.pd_darwin on cgc's site, on a 12" powerbook. Upon putting an alpha object in the chain the object became immidiatly transparent. Even when the colorRGB alpha was set to 1 the object was still transparent. Reducing the colorRGB alpha value does make the object more transparent. Removing the alpha object makes the object opaque again. Also we had some strange issues with pix_movie and pix_film. One would load photo jpg QTs the other would not, one would load DV QT and the other would not. I'm sorry I did not get a chance to log the exact codec and object issues, I was planning on making a more detailed report on the mac but I've had trouble getting access. Also we were using pix_texture2 across the line. sorry about this bug report being vague. I'll get you more details as soon as I can. Thanks Ben

still not able to use gem...
by Gerald Leier 12 Aug '03

12 Aug '03

hi folks, i was wondering if there is any hardware requirements (gfx hardware) for getting gem running under linux with software openglrendering. (glxgears works just fine) after hiting the gemhead button on any demopatch a blackbox with nothing inside appears. got some "cant create double bufferd...." error and thats it. anyone got a clue ? or... may someone plaese tell me that its not possible right now to compile and run gem under linux if this is the truth. i want to play with gem not play arround with gem headerfiles. and for shure am not in the mood for trying to get this thing alive for another 2 weeks. ... any of the developers tried to build the cvs during the last week ? thanks gerald btw. anyone heard of someone else trying to get gem to work for 2 weeks ? under linux with compilation from source. is this default ? cause till now i never have had such problems in getting software up and running.

render order and single buffering
by ben＠ekran.org 10 Aug '03

10 Aug '03

hello all, Is there a way to control the rendering order in single-buffer mode? I seem to get myself in situations when stuff which is rendered last (in time) ends up being hidden behind stuff that was already rendered. Would it be possible to just stack the render order in time? so the first bang to the gemhead gets rendered first, and so on... Thanks! Ben PS: anyone else still use single-buffering?

video1394 under linux : preliminary
by IOhannes zmoelnig 09 Aug '03

09 Aug '03

hi gem'ers i have just committed some changes to the CVS, mainly these are: added new colour-conversions in GemPixUtil.cpp (these should reside in GemPixConvert.cpp (with subclasses GemPixConvert_mmx.cpp and GemPixConvert_altivec.cpp)) rather...) have finally made a working (on my system ;-)) videoDV4L. to make it work, you will have to have libdv2 and libdv2-dev packages installed (on debian systems. on other systems i don't know yet) and you need the dv1394-module loaded (only on new! (should be 2.4.21 i think) kernels). this should create /dev/ieee1394/dv/host0/PAL/in and similar devices with devfs. (you will need these !!) finally, make a [pix_video] object, and send it a "[driver 1(" message (which will switch from video4linux (0) to df1394) features: capture dv in greyscale, yuv and rgba bugs: very unstable (crashes when stopping the rendering chain and reopening it) no resizing (so only native NTSC/PAL resolution) other bugs mfg.a.sdr IOhannes

Hey all, I got it this morning on the first try, Thanks for the notes of persistance! Anyhow I got gemCVS compiled (under linux) and got this error upon loading: /usr/local/gemcvs/Gem.pd_linux: /usr/local/gemcvs/Gem.pd_linux: undefined symbol: _16pix_kaleidoscope.g_pCurrentCosTable /usr/local/gemcvs/Gem: can't load library Could not mean much less to me, but I thought it would post it. Thanks Ben
