i've already tried to make a C++ external from the template but i never reach something which works so if you have a working template please let me know and what about including it in Gem ? as it depends on it (and it may depends on very new feature such as ROI soon) i think it's a better choice + a -- do it yourself http://antoine.villeret.free.fr http://drii.ensad.fr -- Google lit ce mail... si vous refusez cela, utilisez l'adresse antoine.villeret [at] free.fr pour me contacter 2012/12/12 Miller Puckette <msp(a)ucsd.edu>: > I tried and was able to make Gem externals that worked on linux and > Mac OS, but on Windows I wasn't able to link eternals that needed Gem symbols. > This was years ago though, and anyway I might have been missing something :) > > m > > On Wed, Dec 12, 2012 at 01:19:04PM -0500, Hans-Christoph Steiner wrote: >> >> I think the best way to make it easy to find, download and install is to make binaries structured as libdirs and post them on puredata.info/downloads. >> >> I think with a little work that we can make a Gem external template based on the Library Template.

pix_record continues to record, even with rendering turned off
by Antonio Roberts 26 Dec '12

26 Dec '12

I've noticed that [pix_record] will continue to record frames even if the [gemhead] object attached to it is switched off. Is this a bug? I've attached a sample patch, where I'm attempting to take a snapshot from a camera and save it to a video #N canvas 1660 101 564 374 10; #X obj 281 40 gemwin; #X obj 39 118 gemhead; #X obj 39 148 pix_video; #X obj 39 177 pix_texture; #X obj 39 205 rectangle 4 3; #X obj 39 88 metro 10; #X obj 39 59 tgl 15 0 empty empty empty 17 7 0 10 -262144 -1 -1 0 1 ; #X msg 281 10 buffer 1 \, create \, 1; #X msg 189 165 record \$1; #X obj 189 143 tgl 15 0 empty empty empty 17 7 0 10 -257985 -1 -1 0 1; #X msg 137 44 0; #X obj 39 28 loadbang; #X obj 39 285 pix_record; #X floatatom 67 315 5 0 0 0 - - -; #X obj 67 334 change; #X msg 189 205 1; #X msg 189 105 file ./test.mov; #X text 292 104 1- open file; #X text 292 164 2- start record; #X text 292 204 3- capture frame; #X text 422 164 4- stop record; #X text 182 284 Despite rendering not being on \, the pix record object continues to record until it is turned off.

Memory leak in pix_film /pix_movie
by Steffen Kraska 13 Dec '12

13 Dec '12

Hello, i am currently working on a patch that, loads random movie samples into gemwin via pix_film. i reconized memory related crashes, that seem to originate in a memory leak in pix_film. i could reproduce the error with the pix_film helpfile. If you look at pd's used memory, it increases everytime you load a new file and it does not flush, or get empty again. so my pd crashes arround 3GB of ram used my system is a mba 2012 with 8gb ram. pd is 0.42.5 extended (standart download from the website). is there some way to unload the movie, or clear the memory ? any help would be apreciated. greetings steffen

Hello ! Can anyone help ? How can I render a picture with transparent layer ? Or maybe other way to remder and be able to scale and translate picture with no background ? Right now I have to work with 3-D models of the pictures with 0-thick .. but it renders not enough quality as just a picture. But i don;t need backgorund in them and need holes sometimes. Thanks !!
