I can trim them later on with mencoder so not a big issue, but i wish i could understand why this is happening. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=507079&aid=2001887&group_…

gem-0.91.0
by IOhannes m zmölnig 12 Jun '08

12 Jun '08

i have bundled whatever there is in current in the current v0-91 branch and put the files online: http://gem.iem.at/releases/0.91.0 like always, this is full of bugs. the one that is bothering me most at the time is RGBA on osx. the entire codebase is full of inconsistencies regarding the byte-order on big- and litte-endian machines. i think that fixing these will take a long time and a lot of code changes and i am not sure whether we should delay a release any longer. i will hopefully be working on this (at least, if chris isn't faster;-)) in the next weeks and eventually release 0.91.1 as a bugfix release. if you agree i will announce the release on the pd-announce. mfgads.r IOhannes

framebuffer and pix_data
by cyrille henry 01 Jun '08

01 Jun '08

hello, i would like to access color data of a framebuffer. just like pix_data, but working with a framebuffer. i'm specially interested with framebuffer because i need to have more than 8 bit/color (i'd like to use RGB32 format). pix_write use successfully the frambuffer, but i can't make pix_snap to work. is there a solution, and if not, what would be the best to do in order to make this possible? thx cyrille

RGBA confusion...
by IOhannes m zmoelnig 01 Jun '08

01 Jun '08

as hinted in my last email, Gem seems to have different hardcoded ideas about what RGBA means (esp. on OSX) the main confusion is about which "type" to use: GL_UNSIGNED_INT_8_8_8_8_REV vs GL_UNSIGNED_INT_8_8_8_8 the solution seems to be simple (_REV on ppc, normal on i686) but it seems to be done inconsistently in the source code, thus resulting in all the alpha problems marius has reported. i have created a wiki-page that tries to explain the technical implementation of Gem's standard colorspaces, which can be found at http://gem.iem.at/documentation/GemWiki/ColorSpace i have filled this page to my best knowledge, but i would be glad if somebody who knows what they are doing could have a look at it and confirm (or correct) everything (esp. those lines marked with "?") fgmasdr IOhannes
