Re: [osg-users] get OpenGL context
Hi, Thanks for you answer Robert. I have already include GLExtensions. I try to use GLX_NV_swap_group and for example, there is this function : Code: typedef Bool ( * JOINSWAPGROUPPROC) (Display* dpy, GLXDrawable drawable, GLuint group); I search to get the current Display*.

Re: [osg-users] get OpenGL context
Thanks ! I 'm not sure i understand what do you mean for modify src/osgViewer/GraphicsWindowX11.cpp I have found an other solution with the function viewerbase::getWindows(Windows ). If i cast the GraphicsWindow into GraphicsWindowX11, i have acces to the function getDisplay() and getWindow(). But i also need an integer for identify the screen ... For example in this function (the second parameter) : Code: Bool glXQueryFrameCountNV(Display *dpy, int screen, GLuint *count); [/code] -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=35584#35584 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] Image cache and manually release

Re: [osg-users] Image cache and manually release
Thank for your help Sukender. I can't use the methods removeExpiredObjectsInCache and clearObjectCache because the rest of my application need the cache. It is very specific for a module : it loads big images. So i test addEntryToObjectCache. - With NULL in object : OSG make an error (Error file does not contain an osg::Object) - if i call the function with a timestamp to 0 or 0.001 ... but my object is not release. Do you have more ideas ?

Re: [osg-users] Image cache and manually release
Yep ! Your first solution works perfectly ! Thank a lot ! I find an other solution : when you read a file whith readImageFile(..), you specify a filename and you can give option. And there is an option to not use Image Cache. Thank you !

[osg-users] [osgPlugins] ffmpeg synchronisation and frame dropping
Hello, I search to understand how the ffmpeg plugin works. I use a video without sound. If the thread is too fast for the video, there is a synchronisation before publish frame : FFmpegDecoderVideo apply a delay with an internal timer. But if the thread is late, is there frame dropping ? or maybe, the plugin up the video framerate ... ?

[osg-users] [build] Errors in cstdio
Hi,
I am trying to compile osg revision 11782 (version 2.9.9), with Visual C++.
In the project Plugins 3DS, i have a lot of errors since :
1C:\Program Files (x86)\Microsoft Visual Studio 8\VC\include\cstdio(25) :
error C2143: syntax error : missing '{' before ':'
I think it is because we used C code... but i don't know how i can compile
correctly.
Some ideas ?
Thank you!
Cheers,

[osg-users] [osgPlugins] use FFmpeg with Visual C++
Hi, I search a plugin to play video with OSG. I'm working with visual C++. I would like to test FFmpeg but i don't find release for VC++. On Windows, FFMpeg compile only with MingGW.
