String editing
by Thomas Sivertsen 02 Jul '04

02 Jul '04

Hello list, I was wondering if there is a possibility in PD to parse a message like "symbol /home/thomas/qt/regnbueromskip.mov" and then remove the "symbol" within that string? It's a simple string. I need to prepend a read message to the specific file to read it into pdp_qt from Yves Degoyons playlist object. For some reason it doesn't send a message, but a message with a symbol identifier in front. prepending it doesn't work. Something like: [symbol /home/thomas/qt/regnbueromskip.mov] <-- messagebox | [remove the symbol and space] <-- ???? object | [prepend read /home/thomas/qt/regnbueromskip.mov] <-- prepend object Any examples? Thanks in advance! .thomas

compilation question
by Peter Plessas 02 Jul '04

02 Jul '04

Hi! i am sitting here with pd 0.37 sources on debian/ppc, and try to run ./configure --enable-alsa --enable-jack the problem is i don't see the line: alsa is....yes/no no lines about alsa at all, so no messages about alsa being detected or not. when i run make i get a pd version without alsa of course.... sorry if this is an old topic perhaps, but for me it's new. :) regards, Peter~

Memento-ifying
by Chris McCormick 02 Jul '04

02 Jul '04

Hey, Frank B - I am taking some time off tongiht to convert a bunch of GOP patches I've made over to your memento/rradical system. I haven't used OSC or memento before, and i'm just wondering before I launch into it if you have any suggestions for simple patches of your own I should look at for examples. Any other advice for learning how the system works? Rgds, Chris. --------------------------------- chris(a)mccormick.cx http://www.mccormick.cx http://www.sciencegirlrecords.com ---------------------------------

hi, this is weird. it's enough to place a gemhead & a pix_film object. if i load the AVI and start rendering i got 100% cpu load. no texturing, nothing else. pix_videoDS causes gem to crash, if i load a MOV nothing happens. pix_image & texturing on a rectangle works. the same AVI-file plays fine with gem0.87 (same patch, same file) & mediaplayer & everything else. got an error message once: ................the memory could not be "read" here is the test-patch: #N canvas 766 1 355 584 10; #N canvas 435 530 318 448 gemwin 0; #X msg 14 163 create; #X msg 14 186 destroy; #X msg 62 211 0; #X msg 87 211 1; #X msg 62 188 bang; #X obj 15 99 t b b b; #X obj 15 79 bng 15 250 50 0 empty create empty 8 -8 0 10 -262144 -1 -1; #X obj 15 122 del 500; #X obj 62 69 loadbang; #X msg 63 122 buffer 2; #X obj 14 234 gemwin 25; #X obj 64 143 del 1000; #X msg 150 79 dimen 720 576; #X obj 15 25 inlet; #X obj 62 25 inlet; #X msg 116 187 frame 25; #X msg 120 122 buffer 1; #X obj 111 26 inlet; #X text 15 1 create; #X text 61 1 destroy; #X text 110 1 bang; #X msg 174 187 print; #X msg 170 296 border \$1; #X obj 151 296 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 0 1; #X msg 170 317 fullscreen \$1; #X obj 151 317 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 0 1; #X msg 149 101 dimen 640 480; #X obj 151 275 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 0 1; #X msg 171 275 lighting \$1; #X connect 0 0 10 0; #X connect 1 0 10 0; #X connect 2 0 10 0; #X connect 3 0 10 0; #X connect 4 0 10 0; #X connect 5 0 1 0; #X connect 5 1 7 0; #X connect 5 2 11 0; #X connect 6 0 5 0; #X connect 7 0 0 0; #X connect 8 0 9 0; #X connect 8 0 15 0; #X connect 8 0 26 0; #X connect 9 0 10 0; #X connect 11 0 3 0; #X connect 12 0 10 0; #X connect 13 0 6 0; #X connect 14 0 1 0; #X connect 15 0 10 0; #X connect 16 0 10 0; #X connect 17 0 4 0; #X connect 21 0 10 0; #X connect 22 0 10 0; #X connect 23 0 22 0; #X connect 24 0 10 0; #X connect 25 0 24 0; #X connect 26 0 10 0; #X connect 27 0 28 0; #X connect 28 0 10 0; #X restore 19 36 pd gemwin; #X obj 19 18 bng 15 250 50 0 empty empty empty 0 -6 0 8 -262144 -1 -1; #X obj 41 18 bng 15 250 50 0 empty empty empty 0 -6 0 8 -262144 -1 -1; #X obj 20 61 ctlin; #X floatatom 20 86 3 0 0 0 - - -; #X floatatom 46 86 3 0 0 0 - - -; #X floatatom 72 86 3 0 0 0 - - -; #X obj 67 18 bng 15 250 50 0 empty empty empty 0 -6 0 8 -262144 -1 -1; #X obj 101 185 openpanel; #X obj 101 167 bng 15 250 50 0 empty empty empty 20 8 0 10 -262144 -1 -1; #X msg 101 206 open \$1; #X obj 166 288 rotateXYZ; #X floatatom 182 269 5 0 0 0 - - -; #X floatatom 217 269 5 0 0 0 - - -; #X floatatom 253 269 5 0 0 0 - - -; #X obj 166 403 rectangle 4 3; #X floatatom 203 385 5 0 0 0 - - -; #X floatatom 240 385 5 0 0 0 - - -; #X obj 166 362 pix_texture; #X msg 114 363 mode \$1; #X obj 114 343 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 0 1; #X obj 166 184 pix_film; #X obj 166 80 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 0 1 ; #X obj 166 116 gemhead; #X floatatom 209 164 5 0 0 0 - - -; #X connect 1 0 0 0; #X connect 2 0 0 1; #X connect 3 0 4 0; #X connect 3 1 5 0; #X connect 3 2 6 0; #X connect 7 0 0 2; #X connect 8 0 10 0; #X connect 9 0 8 0; #X connect 10 0 21 0; #X connect 11 0 18 0; #X connect 12 0 11 1; #X connect 13 0 11 2; #X connect 14 0 11 3; #X connect 16 0 15 1; #X connect 17 0 15 2; #X connect 18 0 15 0; #X connect 19 0 18 0; #X connect 20 0 19 0; #X connect 22 0 23 0; #X connect 23 0 21 0; #X connect 24 0 21 1; cheers rainer _________________________________________________________________ MSN 8 helps eliminate e-mail viruses.

hello, yes, seems to be a problem with pix-objects. i have made a test-patch with 120 cuboids spinning through GL-space without any problem. but if i load an AVI, cpu load is immedialtly at 100%. i've also tried pix_draw & mode 0/1/pix_texture with no performance improvement. just want to use all this new pix-objects... >>What sort of drive(s) do you have? Also, do you have DMA enabled? RAID 0 array, DMA enabled, 1024MB RAM. with gem0.87 everything is fine on the same machine. cheers rainer _________________________________________________________________ Help STOP SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=features/junkmail
