video vlc plugin osx
by Joson Android 30 Oct '12

30 Oct '12

Dear Gem devs! I would really like make use of the possibilities of opening video with vlc backend, but i don*t get the vlc plugin to work. i compiled Gem modifying the configure like this: PKG_LIBVLC_CFLAGS=-I/Applications/VLC.app/Contents/MacOS/include PKG_LIBVLC_LIBS="-L/Applications/VLC.app/Contents/MacOS/lib -lvlc" ./configure --with-pd=/Applications/Pd-0.43.1-extended.app/Contents/Resources/include/pd/ --enable-fat-binary=i386 --with-ftgl-includes=/sw/include/ --with-libvlc-includes=-I/Applications/VLC.app/Contents/MacOS/include --with-libvlc-libs="-L/Applications/VLC.app/Contents/MacOS/lib -lvlc" i get the "gem_videoVLC.so" file but when i start pd through terminal i can read: pattern : ./gem_video*.so dylib loading file './gem_videoDarwin.so'! dylib loading file './gem_videoVLC.so'! library loading returned: dlerror 'dlopen(./gem_videoVLC.so, 2): Symbol not found: _libvlc_media_add_option Referenced from: /Library/Pd/Gem/gem_videoVLC.so Expected in: flat namespace in /Library/Pd/Gem/gem_videoVLC.so' and in Pd there is only the darwin backend found when i create [pix_video] [pix_video]: backend #0='Darwin' : darwin dv iidc analog does anyone know how to solve this? i am not experienced with compiling, so i have no clue how to proceed. I found a list discussion where similar problem was discussed, but not solved. i use OSX 10.6.8 and pd-extended-0.43.1 i compiled Gem from git so it shows at pd startup: GEM: ver: 0.93.git 305f6a6 thanks in advance John ps: i love gem, and vlc would make it even lovelier

temptation for making Gem build with MinGW
by Hans-Christoph Steiner 22 Oct '12

22 Oct '12

This guy has packaged a lot of libs that Gem needs for MinGW on Ubuntu: https://launchpad.net/~tobydox/+archive/mingw It seems quite conceivable that all of Gem's deps could be packaged this way, then the Gem windows builds could be built on GNU/Linux :-D .hc

gem port to opengl-es - initial developments..
by dmotd 22 Oct '12

22 Oct '12

hi gem folks, i've had a bit of free time to begin porting gem to opengl-es. i'm building and testing with a nokia-n900/RX51 tablet - a debian based arm arch which supports both opengl-es 1.1 common and opengl-es 2.0. initial hacking is concentrated on opengl-es 1.1, which is generally compatible to the opengl 1.0 spec. opengl-es 2.0 uses shaders to replace fixed functions so there is a lot more work involved in replacing core gem functions. i'm using the egl spec for windowing/surface/buffer support, it is cross platform (although afaik apple uses its own modification 'aegl'). it provides basic functionality for reading and writing gl functions to buffer (along the lines of glx), and like glx still relies on operating system apis to supply other interfaces (keyboard / mouse etc). so far: -- cloned gem git, checkout 0.93 tag, created es branch. using glues for basic (incomplete) glu functionality using libglutes for basic (incomplete) glut functionality added additional autoconf tricks to find and test libraries merged the latest git ES branch of GLEW which has experimental support for GLES/EGL added egl drop in for GemWinCreate successful build against pd-0.43 using enable-Controls and others disabled. -- reports: -- libxxf86vm doesn't seem to work properly on the tablet, so for the time being the window modelines are hard coded. there are some other window manager hints that are specific to the device too. gemwin successfully creates the egl window buffer and rendering context. gem crashes when glClearDepthf and glFrustumf are called (both are floating-point variations to the base GL functions and part of the GL-ES spec). furthermore looking at the output of 'nm -C Gem.pd_linux' shows that these functions are not present in the compiled lib, what does this mean? commenting these functions out allows the gemwin to complete init and create successfully. a call to render causes a crash somewhere in the rendering chain (GemMan::render), but i have had little success debugging this issue. -- notes: -- i'm developing with an eye on the raspberry pi project which should bring affordable opengl-es architecture to a small form factor, perfect for installations of (audio)visual artwork - but there's no reason why any recent (jailbroken) mobile/tablet technologies wouldn't be applicable for creative repurposing. before anyone get's excited, the apple 'app store' is still afaik not compatible with gpl code, so it is unlikely there will be a 'rjdj' style app using gem, or likewise any gem based vj app, i don't think the same can be said for google's android platform, but i'm not a user or developer of said platform (or the fruit for that matter). i am coding on a linux-amd64 pc, cross-compiling in scratchbox and testing on the device, using git/scp as a go-between.. this is a bit cumbersome/inefficient - can anyone suggest a virtual machine image (linux based) that provides a graphical gl-es environment and a minimal editor/ide to build and test with? -- i'll keep everyone up to speed as i make developments, and if anyone can replicate my dev environment and wants to contribute i'll happily push to a public git sooner rather than later. cheers, dmotd

new libraries on Mac OS X

I just checked out the gem 0.93.3 Debian package and noticed there are a bunch of new build depends. Should I install these on the Mac OS X build servers too? Here's the list: freeglut libdv4 glew sdl libdc1394 libjpeg8 or libjpeg8-turbo .hc

any word on the Mac OS X 1 frame video bug
by Hans-Christoph Steiner 27 Sep '12

27 Sep '12

There is an outstanding bug where many videos don't play with Gem. Right now, this bug in Gem is the only thing holding back the final release of Pd-extended 0.43.1. http://sourceforge.net/tracker/?func=detail&aid=3517368&group_id=64325&atid… Is there a fix for it that I can include in the Gem version included in Pd-extended 0.43.1 (the most recent Gem release). .hc
