[osg-users] [osgPlugins] ffmpeg plugin and transparency

Hi all, I've been toying with the ffmpeg plugin and osg 2.9.5. As I was hoping, this is definitely a great improvement over the buggy xine plugin. I'm currently adding more playback controls, such as seek and pausing support. I did notice a surprising effect when using a regular

Hi Joe, I recall having similar issues with cross-shared-library casting. I'm not sure this is directly related to your problem, but I thought I'd share. In that case, I was messing up my -shared and -fPIC settings for the g++ compiler. The fPIC setting ensures the generation of

Hi John and Gerwin, I' m also using osgswig... and really would like it kept up with the osg development. Using good python IDE such as SPE, developing osg is much easier (for me) than in C++ . really thanks to all osgswig developers Currently I' m stuck with an svn OSG version (2.9.5)

Hi Gerwin, It's a bit of a tricky situation. The actual content of the alpha channel mainly depends on FFmpeg implementation (and not osg). If I remember correctly, the obsolete colour conversion routines set the alpha value to 1 when the video was only RGB, while the libswscale routines set it

Hi Luigi, Frank and others, FYI I am currently using osgswig with a patched osg 2.9.5. This patch consists of reverting the MixinVector stuff from osg 2.6+ with the standard std:vector alternative in osg 2.4 so osgswig can wrap the VecArrays again. I have tried this only on linux, and I'm not

Re: [osg-users] OSG and shaders

If you add a shader to an object it removes all of the effects of OpenGL's fixed pipeline rendering. As a result if you want any of that fixed pipeline rendering back (such as lighting, texture mapping etc.) you will have to write an equivalent implementation within the shader. K. 2009/8/4

Re: [osg-users] Depth buffer

Sergey, Thanks for the clarification. What happens if you also disable writing to the depth buffer for the icons? You might also have to set render bins to control render order. Earth - icons - objects above earth This will allow all labels to show through the earth, which might not be what

Hi Rick, As well as directly calling Registry to set up the alias, if you know you'll always be using this plugin then you can pre-load the plugin and then you won't need to set up the alias. osgDB::Registry::instance()-loadLibrary(osgDB::Registry::instance()-createLibraryNameForExtension(nsm));

Re: [osg-users] Depth buffer

Here's an idea.. First, apply a ClusterCullingCallback to each icon, with the normal vector being the up-vector at the icon's location. This is prevent icons from rendering behind the Earth . Render the Earth normally, and then also to the stencil buffer. Increase the render bin # of the icons

Hi Alex, You'll need to use a black and white mask over your current texture and blend the two together. To do that you'll need to set the blend function to: osg::BlendFunc( GL_DST_COLOR, GL_ZERO ) and your mask would have a white silhouette of a woman on a plain black background. More detail

Actually having downloaded that picture and loaded it into the GIMP it turns out it's much easier than that. Simply enable blending on the stateset. The image background has an alpha of zero and will then appear transparent. Regards, Kim. 2009/8/4 Kim Bale kcb...@googlemail.com: Hi Alex,
