first email:
"in the current implementation of osgUtil::RenderStage::drawInner() method, there is some wrong assumptions made. The problem is, that whenever one does use multisampling functionality, the Blit operation (which suppose to copy the content of multisampled FBO into the usual one) doesn't perform well in some cases.
I've attached a corrected version of the RenderStage. It do just add one line, which enables the multisampled FBO as a readable just before the usual FBO is set as writable. With these corrections the Blit operation performs now correct and allows using of multisampled rendering results further."
second email:
"There was a problem when blitting the multisampled FBO with internal formats. The default internal format of color buffered multisample FBO was GL_RGBA. This has converted the color values whenever the FBO content was copied. I've added couple of lines, which do just enable the multisampled FBO internal format in respect to the attached color texture's internal format. This makes it possible to blit even float valued texture, so make HDR with multisampling possible ;)"
FREETYPE_INCLUDE_DIR_freetype2.
The error case was that during first cmake run (unspecified
ACTUAL_3RDPARTY_DIR) FindFreeType set these to xxx-NOTFOUND. After
specifying ACTUAL_3RDPARTY_DIR, Find3rdPartyDependencies warn't able
to change these (without FORCE).
I also added freetype237 to the library search list since it is what's
in my binary dependencies for vc90"
I eventually found out that it was now disabled (the mailing list
archive tells me it is because of multithreaded write issues with
vpn). I then decided to use osgarchive to make it myself from the
generated output. However if one of the insert parameters is a
directory, it won't be able to find them. The attached versions
corrects this."
" + "Further improvement for conversion to IVE format. Compressed DDS files are written for IVE output when noTexturesInIVEFile option is defined i.e. osgconv --compressed -O noTexturesInIVEFile dir1/input.osg dir2/output.ive will write images into dir2."

It's really just a cut-paste job from the existing LINE support.
The current dxf plugin architecture isn't very efficient, especially if you
are loading large point clouds (LIDAR)
eg. it makes multiple lookups of the layer name for each vertex.
I don't know if I can improve this for the general case or if I have to add a
special large point cloud dxf reader."
equivalent to the GLSL shaders sample) that displays the forest with
shaders on Intel 945 GM hardware. This card supports OpenGL 1.4 and
ARB_fragment/vertex_program only.
I would be pleased if this change made it into the official set of
examples, as it illustrates the use of ARB shaders quite nicely. I did
not find any other example covering this topic."
It\u2019s a one line change against OSG 2.8.0 (see line 196). I\u2019ve already tested the change, and confirmed it\u2019s fixing the crashes described above."
It basically removes the static init() and exit() functions,and move them inside the observer class (the one that cleans everything up when the last media is unloaded).
It also add an extra check to clean up on exit if the QuickTime env is initialized, but no media is succesfully loaded / written (it might happens with streaming resources).
I tested it under WinXP with zero, one and multiple videos.
Stephan reads in copy: could you kindly check if everything runs smooth under OSX as well? Also, have you got a chance to test it with streaming media?
