It expects 'src_pix_fmt' and 'dst_pix_fmt' to be of type 'PixelFormat' rather than int. The attached cast fixes this (for me).
I've also added Matroska video to the list of supported extensions"

avoid possible trouble, gcc warns about this. Attached modification
fixes the initializer order to silence this warning."
Also, there was also a small bug in osgDB's CMakeLists.txt that was causing an error when I tested with CMake 2.4.4.

Very simple cases of state configuration are supported (all the ones I really need):
- single per pixel not attenuated non spot light source ON/OFF
- exp2 fog ON/OFF
- diffuse texture in rgb + optional specular gloss in alpha (Texture unit 0) ON/OFF
- normal map texture (Texture unit 1 and Tangent in VertexAttribArray 6) ON/OFF
- blending and alpha testing (not in shader pipeline)

ADD_LIBRARY(${TARGET_TARGETNAME} MODULE ${TARGET_SRC} ${TARGET_H})
which gives them .so extensions. Since ".so" != ".dylib" osgDB::listAllAvailablePlugins finds no plug-ins. I believe the correct solution is to use CMAKE_SHARED_MODULE_SUFFIX instead. This builds and runs correctly on OS X but I have not tested on other platforms.
Attached is an updated src/osgDB/CMakeLists.txt based on rev 9915. The change is at line 108. To validate: build and then run bin/osgconv --formats. You should get many screenfuls of plug-in features, extensions and options."
At the company where I work we model literally thousands of 3DS models for all types of objects. Most don't have transparent textures applied to them, but a few do. The issue is that a texture may have an alpha channel defined, yet its 3DS material definition is not marked as being an alpha source, or transparent. This can happen for any number of modelling reasons (so I'm told) but the net effect is that when a 3DS object is loaded with such a material applied, the stateset creation for the 3DS geometry omits to add the GL_BLEND attribute as neither of the conditions that it currently tests for are satisfied under this scenario.
However, one thing that is apparently an indication of transparency/alpha information that we do make use of when modelling, but that the 3DS reader omits to test, is that we assign to the transparent texture to the opacity_map of the 3DS material structure.
Now, having discussed with our modellers the theory behind the opacity map, it seems that it is safe to say that if an opacity map is specified, then the reader should really apply the GL_BLEND attribute as it is an indication of some form of blending being required between materials.
With this in mind, I have made a minor change to the function createStateSet below, from the ReaderWriter3DS.cpp file, that checks for an opacity map having been specified, and in such a scenario the GL_BLEND attribute is applied to the geometry. This fixed our issue, and thought it might be helpful to others."
When 2 geometries are merged, the primitive sets of the second geometry
are copied to the first geometry.
The primitive sets were copied with a std::insert into the first geometry
primitive set vector. It doesn't work when the geometry is using VBOs (because
the element buffer object of the primitive set is not updated).
The correction replaces
lhs.getPrimitiveSetList().insert( lhs.getPrimitiveSetList().end(),
rhs.getPrimitiveSetList().begin(),
rhs.getPrimitiveSetList().end() );
by
for( primItr=rhs.getPrimitiveSetList().begin();
primItr!=rhs.getPrimitiveSetList().end();
++primItr )
{
lhs.addPrimitiveSet(primItr->get());
}"
Node::Node(Node &node, copyop) :

It doesn't call the setStateSet method of osg::Node (or osg::Drawable). So the parent
list of the state set is not updated with the new node (drawable)."
some stuff out into DarwinUtils.h/.mm so both implementations can share
some of the code. There's even a bugfix for GraphicsWindowCarbon, which
fixes some issues with multiple windows on different screens."
On destruction of some static variables, the global referenced mutex is used
to lock access to the parent lists of state attributes, nodes and so on.
This even happens past the mutex is already destroyed.
This change to Referenced.cpp revision 9851 uses the same technique like the
DeleteHandlerPointer already in Referenced.cpp to return an zero pointer for
the global referenced lock if it is already destroyed."
"There is error in WoW shader, you can see it by this simple example:

Clear color may be choosed any with at least one component equals to 0

Note from Robert Osfield, flipped the orienation of the zoom to make the right mouse key zoom and the scroll wheel work in the same direction.
Single features are implemented as bits asother enums in ReaderWriter class already does, so that combinations are possible and fast comparison operations are possible
By default all features are enabled.
I have added this virtual method to the dot plugin to get an idea how to use these features.
With this patch osgconv --formats shows an additional line 'features' for each plugin"
Because there already exists the option to convert slow path geometry to the fast path by computing an internal fast path alternative, I added a new optimizer option that automatically does this. To check the results I also made some changes to the statistics gathering and rendering.
Somewhat unrelated, but also part of the optimizer I disabled removal of CameraView nodes during RemoveRedundantNodes optimization.
As discussed on the ML, CameraViews were removed from the scenegraph. This solves that issue.
Summary:
-Geometry::areFastPathsUsed now also looks at internalOptimizedGeometry
-Added Optimize option to make all slow path geometry compute their internal fast path alternative
-Added fast geometry counter to the statistics
-Disabled removel of CameraViews in optimizer
