Re: [PD] latency

I've managed to get it down to 15ms on a g4 1ghz powerbook with a motu828mkII .. but nothing below that. 12ms almost works.. but 10 and under are a complete mess. is this because of portaudio on os x? or is there something i can do about it? i know that the motu will do 3-4ms with max/msp and reaktor, but not with pd. matt. > > From: plessas(a)sbox.tugraz.at > Date: 2003/11/15 Sat AM 08:58:08 EST > To: pd-list(a)iem.at > Subject: [PD] latency > > dear list, > > who managed to run pd with less than 30 msec of latency? > how do you do that? > > i tried: > osx on a g3 pismo (~500MHz) > osx on a g3 pismo (~500MHz) using an rme/hdsp > win2k on a P4 2.5GHz using asio and an rme/hdsp > and nothing less than 30msec! > > thanks for any replies! > > peter_p > > > _______________________________________________ > PD-list mailing list > PD-list(a)iem.at > http://iem.at/cgi-bin/mailman/listinfo/pd-list > 1

Hi Ive just installed the latest 0.888 pre 1 version of GEM from Chris Cleppers site. Where can one get a list of the updated features? Ive tried getting antialiasing working, using the fsaa message to gemwin, but was getting errors?(this was mentioned earlier on the list by B. Bogart). Is this supported only on certain hardware, or at all on OS X ? If so, what is the syntax? Now that the text objects are compiled in, (and it seems aliasing is enabled for them, at least in the docs..?), is there a way to get the text to have some depth? Ive tried a variety of messages, and nothing seemed to work (except 'depth' in line rendering mode.., which changed the thickness of the lines). Thanks, -dok

More Gem help for Blockhead-Me please?
by Wade McDaniel 25 Mar '04

25 Mar '04

Hello pd-listers~ I was hoping someone could tell me if pix_data can read from a openGl chain (e.g. from the rasterization frame) or if it only works with objects like pix_video? Im writing a patch that will eventually read from a pix_video object and map that onto a cube that fills the screen, and read pixeldata from that, but as I dont have my camera now, I want to test my patch by moving a cube around in 3-space and testing the fields of pixels the patch is looking at in the window. I cant get any data from pix_data with a white cube sitting right in the middle of the window. I tried x:400 y:300 (screen dimentions are 800x600) and x:0.5 y:0.5, both failed. I have the chain hooked up as follows: [gemhead] [translateXYZ] [pix_data] [cube] and I tried: [gemhead] [translateXYZ] | \ [cube] [pix_data] both failed... Also, B. Bogart said that I can change the bounding box of gem by using the [view< message. Whats the syntax for that message? Thanks for the help B and everyone! -wadeislost

pthread_setschedparam problem on OSX + fix
by cgc 17 Jan '04

17 Jan '04

I've been meaning to post this change for a long time, and have been negligent about it. The pthread_setschedparam() hack that helps pd's audio not drop on OSX is absolutely fatal when used with GEM. The reason for this is that OSX uses OpenGL for the entire UI and GL requires context switches to handle multiple applications sharing the hardware. When Pd sets it's pthread priority higher than the UI, this context switch can be blocked resulting in a complete lockout of UI events as GEM grabs all the CPU resources and refuses to relinquish the context. The fix is to add the -rt option as prerequisite and not make this the default action (a check to make sure GEM is not loaded would be good to have as well): #ifdef MACOSX if (sys_hipriority) { struct sched_param param; int policy = SCHED_RR; int err; param.sched_priority = 80; // adjust 0 : 100 post("pd: real-time mode - using pthread_setschedparam\n"); err = pthread_setschedparam(pthread_self(), policy, &param); if (err) post("warning: high priority scheduling failed\n"); } #endif /* MACOSX */

gop's and labels
by mik 01 Jan '04

01 Jan '04

hi there seems to be going something wrong with the labels in gop's. they disappear from the properties box and as a consequence from the gop too. at least, that is the case for bangs (latest pd). i also still have this "bad screen distance" problem with plugin~ which nobody else seems to have experienced up to now (yes, i keep whining about it, because i can't use all those beautiful ladspa-gui's i made anymore). greetings m
