Anyone know a fix here? the simplest _workaround_ is, to create a custom font where all the characters you want to display are mapped into the range 0..255 this obviously won't work, if you have alphabets with a large number of glyphs (like japanese if you want to display every possible character) if anyone has a real fix, i'll be happy to incorporate it into the sources... mfgadsr IOhannes ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] [pdp]/[gridflow] trying to use a webcam
hi all i've run into big troubles trying to use an usb cam with either gridflow or pdp, but it doesn't want to work in both. i wonder if i am doing big mistakes or what combination of drivers and cams work with gridflow. history: # i tried two different models yet: -philips spc900nc -logitech quickcam pro 4000 both are supported by pwc-driver from http://saillard.org/linux/pwc/ . # together with that driver, there is also a usefull tool available 'setpwc', that is used to set some camera-specific settings, that are noth supported by 'dov4l', to commandline tool used to set general web-cam and tv-card settings. # both tools work fine here and i can test the various settings with the program 'camorama'. with camorama i have no troubles to display the picture from the cam and different options work fine (e.g. 320x240/30fps or 640x480/15ps). # but with neither pdp nor gridflow i had luck. for me it is more important that it works with gridflow, also because it is still maintained. that's why i post here only what i tried with gridflow # note: it seems that the according objects in gridflow and pdp [#in] and [pdp_v4l] overwrite some settings in the cam when instantiated. that makes it even more difficult to find a set of settings that just works. # my steps to get a picture with the logitech quickcam pro 4000 and pd/gridflow: -i plug the cam into the usb-plug -'setpwc -d /dev/video1 -p' tells me all actual settings of the cam: - setpwc v1.1, (C) 2003-2005 by [EMAIL PROTECTED] Current device: Logitech QuickCam Pro 4000 VIDIOCPWCPROBE returns: Logitech QuickCam Pro 4000 - 740 Serial number: Resolution (x, y): 320, 240 Offset: 0, 0 Framerate: 10 Brightness: 32256 Hue: 65535 Colour: 32768 Contrast: 0 Whiteness: 0 Palette: YUV 4:2:0 Planar Compression preference: 1 Automatic gain control: -1275 Whitebalance mode: auto Blinking of LED is not supported by the combination of your webcam and the driver.

There are problems with pdp and the pwc driver. pdp was designed with the old closed-source driver and does not work properly with latest open source version. The solution is to remove the pwc-specific code from the pdp source and then it will be treated like any other webcam. Details in this post: http://elists.resynthesize.com/pd-list/2005/07/1505225/ I have a Quickcam Pro 4000 myself and had great success using it with pdp after making this change.

Re: [PD] running PD from a USB stick / drive
Going from scratch for a single purpose USB boot I would go the DSL route because it's so easy, thre's a make USB install script that adds a filesystem, isolinux and installs the rootfs and all that stuff for you. Another script allows you to work on the custom image using apt so it's straightforward to remove lots of stuff to strip it down without falling into dependency hell, then just add the Pd/GEM deb packages. You could probably keep it down below 64M with a bit of care.

There are so many services I was fearful of screwing up my machine. I guess I was now frustrated enough to try anything. I ran services.msc and disabled everything else and pix_video worked!

Re: [PD] CPU cost II
You couldn't reasonably tag every object with a cost because that might change for many reasons, but you can know the load of an object or patch on your current CPU using the [cputime] object which shows a percentage scale. You can usually use it to work out the heavy offenders by muting DSP with [switch~] and seeing what is using up lots of cycles, but it's not really accurate benchmarking.

[PD] curious Pd behavior
Hi all, In my recent performance, I've noticed a peculiar PD behavior. Now, before I ask for your advice, please allow me to state that the problem has not been as pronounced in the past as it was on this performance. Nonetheless, it was more or less persistent. For this reason, I am asking for your thoughts on it. Here's the hw/sw scoop: AMD64 3000+ laptop RME HDSP Multiface Linux 2.6.15 Kernel (real-time enabled, can't recall if it is preempted) ALSA JACK Pd (0.38.4) -rt running MIDI/Display interface for performer/DSP 2 x JACK-RACK with 4 LADSPA plug-ins each 2 x QSynth The entire setup consistently eats approx. 80% cpu (no spikes). Pd also had pyext (0.1.3) and a couple of simpler externals (yes, stuff is a bit outdated...). All audio is diffused (and partially processed) via Pd. What happens during the runtime is two interesting issues: 1) if I start Pd by clicking on a link (no terminal) the pyext does not output anything when DSP is on, but as soon as I turn DSP off, it spits out backlogged data. However, when I start pd from a terminal, everything works ok. Any ideas as to why? 2) when CPU usage climbs above 50%, Pd starts going out of sync by initiating opening queue twice which obviously throws entire piece out of sync. Interestingly, this only happens approx. 50% of the time (randomly). As the CPU usage grows, it becomes worse. This is not a problem when CPU usage is lower. Than 50% and never a problem when using built-in soundcard (this was not a problem before, so it may very well be that it is my setup). 3) when restarting DSP, some of the routed signal going through Pd to the output is lost at random times. This was in part a problem before as well. So, while I am aware very much that this may be peculiar to the versions I used, and/or possibly due to use of a custom (possibly buggy) build of a kernel, I was wondering if anyone had an alternative explanation for this kind of behavior. Many thanks!
