Re: [PD] installing PD on osX
by thewade 03 Jun '05

03 Jun '05

So the 0.39test2-rc0 file is the .app file? Is there an installer for jack on osX with qJackCtl (or some osX equiv)? Could you include zexy in the .app please? Thanks for all the help all! Especially with osX (is it a BSD derivitive BTW?) and not being able to look at the screen. And she that I assist is not really a computer nerd either... yet. I am still working on that! Thanks again! -thewade

DSP schedule problem
by thewade 02 Jun '05

02 Jun '05

Hello list! I am having a problem. I have created a little console patch and I am trying to get the effect send-recieve functionality working. (See picture http://root.aproximation.org/pdProb.jpg ) I am sending out some of the signal from each channel out what would be the effects send to the bank of allpass filters, but when I connect the allpass filters to the effect recieve I get an error - Error: DSP loop detected (some tilde objects not scheduled) - and sound cuts out. How do I get my object to be able to send from two of the 5 outlets, and recieve into two of the 5 inlets? Thanks for the help! I am totally at a loss here. -thewade

[OT] PC hardware recommondations for Linux
by B. Bogart 02 Jun '05

02 Jun '05

Hey all, This is pretty off topic. I'm trying to figure out what PC to buy for my next linux machine. This machine is going to be specifically for PD/Gem stuff, maybe a little video here and there, but is meant to be a machine I don't depend on day to day, but can lease for installations and/or performance stuff. So it has to be solid. My current PC is a duron 800 Abit KT7 with geforce2 card in it. I'm hoping to get some performance getting close to my g4 1.25Ghz powerbook with Radeon 9600. For the graphics I'm looking at the Asus N6600 (256MB, FX6600) but I'm stuck on the mainboard. And will probably be running an AMD XP 3000+ or 3200+ A windows guy recommended the Asus a7n8x-e deluxe which sounds really great but I'm (clearly) worried about linux compatibility. I did a few searches online and found very inconsistant reviews, for some people everything works, for others almost nothing works. If I get this board I would like all features to work, that is all usb ports, the 1GB ethernet, the firewire (for Gem), and the 6 channel audio. So are any linux PDers using this board and would recommend it? Any hoops you had to jump through to get things like the sound to work? all 6 channels? Does the ethernet work without troubles? Also I'm going to be running dual 160GB SATA drives in RAID to get the best disk access bandwidth I can manage. Also I'm considering the debian family, angula, ubuntu and the like. RAID hard to set-up under these? I'm also looking at the A7V880 but Its hard to see the difference between the two boards. So if anyone is using these boards with PD under linux and (hopefully) actually using all the features, like all the audio channels, the firewire input, the Gb ethernet please drop me a line. Or if you just got a comperable PC and are very happy running linux on it let me know. Thanks all. b>

GEM Linux and video codecs
by Etienne Desautels 02 Jun '05

02 Jun '05

Hi list, I'm developing a patch in PD/Gem on Linux where I'll have to play many hi-res videos at the same time. I did some research to find the best codec with the lowest CPU usage on Linux. I found that there's not a lot of well optimize codecs on Linux. Patrick via Ben B. told me that after a lot of testing he found that MPEG2 was the best choice. After some testing I found mostly the same thing: MPEG2 or MPEG4 are the most optimize codecs on Linux. I did also some testing with different libraries for playback. LibMPEG2 (MPlayer is using that one for MPEG2) is the fastest one for MPEG2 follow by FFMPEG. In my case I'll only play the file from start at normal speed, so it's not a problem if the codec have temporal compression. Just to give you an idea, I can play a 800x440 px, 24fps at a really good quality and using less then 15% of CPU on an P4 2,6GHz in MPEG2 with LibMPEG2 ! So here's my questions. I tried to compile Gem with FFMPEG support and it always fail in one manner or another. Or it doesn't build at all, or it build but when I load Gem I got this error message (undefined symbol: ogg_stream_init Gem: can't load library), or everything seems OK but when I try to load a movie, any type, in pix_film, FFMPEG always say that it doesn't support this format. So I can't play MPEG2 or MPEG4 in Gem, except with other less (very less) efficient libraries (it take around 50% CPU to play the same file with LibMPEG3). I did my compilation test on Unbuntu (Debian) and I try with the distro installation of FFMPEG and also with a version I compile myself (this one is more efficient in CPU usage). I tried with both Gem 0.90 and the CVS version. Same result. Could someone help me compiling Gem with a working FFMPEG ? I'm using PD 0.37 Also, what I would really prefer is to had support in Gem for LibMPEG2. Do you think it could be difficult to do ? Is it about creating a filmMPEG2.cpp and filmMPEG2.h files with the good function calls to the library and add the reference into the pix_filmNEW.cpp ? And I would like to know what's the best container (.mov, .avi, .mpg, raw) to playback video in Gem. One last thing, I was not able to use FSAA. My video card is an ATI 9600 and I'm using the binary driver with x.org. I put the lines to enable FSAA in my X86-config-4 file without any success. Any ideas ? Thanks and sorry to ask so much questions in one time. Etienne
