Re: [osg-users] [build] [Tutorial] Building osgAndroidExampleGLES1/2 on Ubuntu 11.10
Hi koduri, A silly question... Did you compile ffmpeg for android first? Without osg? You need the ffmpeg library compiled for android in order to use it later to compile against osg. Cheers.

Re: [osg-users] [osgPlugins] FFMPEG plugin Problem on Android
Hi Koduri, There is a submission in osg-submissions that I believe includes a port of the ffmpeg to Andriod including other changes. I've reviewed it a couple of times but haven't merged these changes yet as they are rather intrusive and I'll need to explore further the potential fallout in breaking old builds, for yourself you are best having a look at though as you won't have legacy issues.

[osg-users] R: Multisampling
Hi, I was about to ask the same question. And I tried what you suggest to remove multisampling from one node, but it does not work. I mean, once you set the number of samples in the display settings, and create a rendering context based upon such display settings, then it is impossible to disable multisampling. BTW, I also tried to directly call in the DrawImplementation of my own drawables this statement: glDisable(GL_MULTISAMPLE); but it does not work either. I mean, once set, multisampling seems not to be controllable. Did I miss something? Does it depend on OSG? Or driver bug?

Re: [osg-users] [build] [Tutorial] Building osgAndroidExampleGLES1/2 on Ubuntu 11.10
Hi Koduri, I believe you are simply not compiling the plugin. You should modify CMakeModules/OsgAndroidMacroUtils.cmake and add the ffmeg plugin to the ANDROID_3RD_PARTY macro, or you can also do this ugly hack: go to the root CmakeLists.txt and add FIND_PACKAGE(FFmpeg) after the line 492 after the ANDROID_3RD_PARTY() is called. Hope it helps. Cheers. 2013/1/29 Koduri Lakshmi ankiredd...@gmail.com Hi Jordi Torres, Thank you very much your kind help. I too trying to identify the problem. ... Thank you!

Re: [osg-users] Creating a billboard shader for OpenGL ES 2
Preet, Perhaps the problem is lack of precision in your BillboardRotate uniform (double - float). Maybe you can try a different approach: transform your vertex into View space (or Clip space) and then apply the ModelPosition offsets there. Just an idea. Glenn Waldron / @glennwaldron On Sun, Jan 20, 2013 at 5:35 PM, Preet prismatic.proj...@gmail.com wrote: Hiya, This is somewhat related to my last thread (maybe I should have just explained the situation from the beginning). I'm trying to create a shader that does billboarding for hundreds of objects at once (where using AutoTransform is too slow). I merge all these objects together to reduce the number of draw calls, and pass along specific vertex attribute data (specifically model-space relative vertex data when I want the billboard center to be the model's center) and uniforms (camera vectors) to do the required billboard transform in the shader. This kind of works, but the result is 'jittery' compared to AutoTransform. I don't know whether its the way I specify the uniform update callback or if its related to reduced shader precision (the coordinates I used are all close to the origin though, so I hope that's not the case) or something else entirely. I created a minimal example that reproduces the issue [1]... (just copy-past-compile). The example shows a square billboarded with AutoTransform working perfectly, and my not so great example directly behind it. [1] https://gist.github.com/4582261 * Does anyone know why my example billboard implementation causes that jitter/delay? * Or, has anyone created a better shader that can do billboarding for batched geometry (and if so, could they maybe share how)?

Re: [osg-users] Method for Converting FLT files to use DDS Textures
I'll second Robert's suggestion of simply loading the .FLT file, programmatically changing the texture references, and exporting back to .FLT. This seems like the easiest approach, so you should probably try it first before moving on to more elaborate solutions. The potential problem is that the .FLT importer or exporter might drop some .FLT features that your (non-OSG) rendering software depends on. -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Method for Converting FLT files to use DDS Textures
Yeah, it should be a piece of cake to do a binary search and replace for .RGB and replace them with .DDS in your FLT file. I know of a couple of binary file editors that should be able to do this without damaging the FLT file.

[osg-users] osgviewer - OS X
I'm looking for some help on getting osgviewer working under OS X. Specifically, osgviewer doesn't open a window and display the specified osg (cow.osg). I've read through the FAQ on this question and have set DYNLD_BIND_AT_LAUNCH environment variable. I've also set OSG_NOTIFY_LEVEL=INFO and now OSG_NOTIFY_LEVEL=DEBUG but don't see anything obvious (output below). It looks like it is loading the .osg file, but then just hangs w/o an error. I installed OSG via MacPorts. Debug output indicates that it's finding the libraries and plugins. I'm brand new to OSG. Any suggestions you might have on where to go next in the debugging process would be very helpful and welcome.

Re: [osg-users] [build] [Tutorial] Building osgAndroidExampleGLES1/2 on Ubuntu 11.10
Hi Jordi Torres, Thank you very much for the great help. I changed CMakeList.txt file and started compiling. Now i am getting the following error. Code: In file included from /home/ttpl/Android/OSG/ffmpeg_Plugin/OpenSceneGraph-3.0.1/src/osgPlugins/ffmpeg/FFmpegHeaders.hpp:12:0, from /home/ttpl/Android/OSG/ffmpeg_Plugin/OpenSceneGraph-3.0.1/src/osgPlugins/ffmpeg/FFmpegClocks.hpp:10, from /home/ttpl/Android/OSG/ffmpeg_Plugin/OpenSceneGraph-3.0.1/src/osgPlugins/ffmpeg/FFmpegClocks.cpp:2: /home/ttpl/Android/OSGSupport/ffmpeg/libavcodec/include/avcodec.h:30:33: fatal error: libavutil/samplefmt.h: No such file or directory This problem may solve if I consider the latest submission. But as I am new to submissions I am not able to handle it. I saw a post on submissions about ffmpeg fiexs. But I don't know how to download it and how to replace the download ones in the source code. Please excuse me if it is not worthable question to ask here. ... Thank you!

[osg-users] Fedora 18 with nVidia driver: OSG crashes session
Hi, I recently upgraded a system from Fedora 17 to 18 (64-bit KDE spin). I am using the rpmfusion nvidia drivers and the upgrade (using the new fedup) seems to have gone well. Problem is, now my OSG applications as well as osgviewer crash my session instantly and send me back to the login screen! I didn't have any problem on Fedora 17. I did all the normal post-upgrade cleanups (distro sync, etc.) and all the OSG packages seem to be properly upgraded to the latest 3.0.1.1-3.fc18 versions. There is clearly something seriously wrong here. Any ideas? I'm happy to help debug this further.
